Embodiments of the disclosure relate to cyber security. More particularly, embodiments of the disclosure related to an electronic device and method directed toward malware analysis using multiple software applications and multiple plug-ins, where the combination of software applications and plug-ins is dynamic.
Over the last decade, network devices that access the Internet or other publicly accessible networks have been increasingly targeted for malicious attack. These malicious attacks may simply involve the use of stolen credentials by an unauthorized person in efforts to gain unauthorized access to information stored within a network device. However, other malicious attacks may be more complex.
In general, one type of malicious attack is an exploit attack. An exploit attack is an attempt, normally through unsuspecting uploading of an exploit (e.g., software, data, command(s), etc.) to take advantage of a vulnerability in a targeted computer by adversely influencing or attacking normal operations of that computer. Typically, exploit attacks are directed to a vulnerability associated with a specific application (e.g., browser application, document reader application (such as a portable document format “PDF” reader), Microsoft® Office® or another type of data processing application, etc.) or a vulnerability found in a specific plug-in associated with the application (e.g., Flash™ plug-in, Java® runtime environment (“JRE”), etc.).
Another type of malicious attack may involve the insertion of malicious software into a computer or another type of computing device. The malicious software may include any program or file that is harmful by design to the computing device. The malicious software may include computer viruses, worms, Trojan horses, adware, spyware, and any programming that gathers or attempts to steal information from a computer or about its user or otherwise operates without permission. The owners of the computers are often unaware that these programs have been added to their computers and are often similarly unaware of their function.
Various processes and devices have been employed to prevent malicious attacks and other security threats. For example, computers often run antivirus scanning software that scans a particular computer for viruses and other forms of malware. The scanning typically involves automatic detection of a match between content stored on the computer (or attached media) and a library or database of signatures of known malware. However, this type of static analysis produces a number of false negatives, as detection is solely dependent on the presence of generated signatures, which may not be available until weeks or months after initial detection of a particular type of malware.
Another type of threat detection solution employs virtual machine instances (VMs) to replay the processing of an object within a sandbox established by those VMs. This solution monitors the behavior of the object during processing within a VM and may signal that the object (e.g., uniform resource locator, a file, etc.) is associated with a malicious attack in response to detecting anomalous behavior(s). One such system offered by FireEye, Inc., the assignee of the present patent application, employs a two-phase malware detection approach to detect malware contained in network traffic monitored in real-time. In a first or “static” phase, a heuristic is applied to an object that appears to be “suspicious” by exhibiting characteristics associated with malware. In a second or “dynamic” phase, the suspicious objects are processed within one or more virtual machines and in accordance with a specific version of an application or multiple versions of that application. Although the two-phase, malware detection solution may offer concurrent processing of two or more versions of an application in order to achieve significant reduction of false positives while limited time for analysis, this analysis may not take into account the totality of the software environment when analyzing the content for malware.
Embodiments of the disclosure are illustrated by way of example and not by way of limitation in the figures of the accompanying drawings, in which like references indicate similar elements and in which:
Various embodiments of the disclosure are directed to a threat (malware) detection system for multiple application (“multi-app”), multiple plug-in (“multi-plugin”) analysis of a suspicious object within a sandbox environment, where the suspicious object may include one or more data elements (e.g., files, documents, etc.) and/or one or more uniform resource locators (URLs). Herein, the sandbox environment features one or more virtual machines, each virtual machine includes launcher logic that is responsible for setting an analysis environment variation framework for analysis of a suspicious object for malware. The analysis environment variation framework, referred to herein as a “multi-app, multi-plugin processing framework,” includes multiple application/plug-in combinations that, when launched, process the suspicious object concurrently (i.e. overlapping at least in part in time) in the virtual machine. During processing of the suspicious object, the behaviors of these application/plug-in combinations are monitored and analyzed to determine whether the suspicious object is associated with a malicious attack.
The setting of the multi-app, multi-plugin processing framework may be based, at least in part, on the type of object for analysis and received configuration data. The configuration data includes one or more priority lists (hereinafter “priority list(s)”) that, for each object type, provides a prescribed order of execution for applications (and/or application/plug-in combinations) on an application basis and/or a plug-in basis. The configuration data may further provide information to control how and when the given object (e.g., file or URL) is processed using multiple versions of an application. For example, a delay between commencement in the processing of a suspicious object by one application/plug-in combination and another application/plug-in combination can change dynamically. Also, the processing of the suspicious object may be halted when sufficient indicators are observed, so that VM analysis time can be conserved.
The adjustment and substitution of different plug-in combinations provides a secondary variance to a multiple application malware detection analysis. Depending on the object type and the selected applications (and version), the plug-in types may be changed so that different versions of applications that process the suspicious object with the VMs also utilize different plug-ins or different plug-in combinations. This plug-in multiplexing enables a threat detection system to be dynamically programmable, which allows the system to mimic application/plug-in combinations that may be utilized by a targeted customer (e.g., enterprise or other organization protected by the threat detection system) as well as application/plug-in combinations that may be more susceptible to malicious attack or the most fortified (e.g., patched or otherwise updated) application/plug-in combinations—thus providing ability to detect both new and older malicious attacks.
It is contemplated that the priority list(s) may include, besides different versions of a plug-in for a particular application type or version, different versions of an operation system (OS) that may be more susceptible to a malicious attack on a particular application and/or plug-in. Hence, the priority list(s) may feature different OS, application, and/or plug-in combinations. For simplicity, however, the priority list will be described in connection with application/plug-in combinations.
In the following description, certain terminology is used to describe various features of the invention. For example, the terms “logic,” “engine” and “component” are representative of hardware, firmware or software that is configured to perform one or more functions. As hardware, logic (engine/component) may include circuitry having data processing or storage functionality. Examples of such circuitry may include, but are not limited or restricted to a hardware processor (e.g., microprocessor with one or more processor cores, a digital signal processor, a programmable gate array, a microcontroller, an application specific integrated circuit “ASIC”, etc.), a semiconductor memory, or combinatorial elements.
Logic (engine/component) may be software such as one or more processes, one or more instances, Application Programming Interface(s) (API), subroutine(s), function(s), applet(s), servlet(s), routine(s), source code, object code, shared library/dynamic link library (dll), or even one or more instructions. This software may be stored in any type of a suitable non-transitory storage medium, or transitory storage medium (e.g., electrical, optical, acoustical or other form of propagated signals such as carrier waves, infrared signals, or digital signals). Examples of non-transitory storage medium may include, but are not limited or restricted to a programmable circuit; non-persistent storage such as volatile memory (e.g., any type of random access memory “RAM”); or persistent storage such as non-volatile memory (e.g., read-only memory “ROM”, power-backed RAM, flash memory, phase-change memory, etc.), a solid-state drive, hard disk drive, an optical disc drive, or a portable memory device. As firmware, the logic (or engine/component) may be stored in persistent storage.
The term “multi-app” is used to represent multiple versions of an application and/or different applications. Similarly, the term “multi-plugin” is used to represent multiple versions of the same and/or different plug-ins.
The term “object” generally relates to any type of information, including a Uniform Resource Locator (URL) or a data element, which is broadly defined herein as a collection of data, whether in transit (e.g., over a network) or at rest (e.g., stored), often having a logical structure or organization that enables it to be classified for purposes of analysis for malware. Examples of different types of data elements may include a self-contained element, one or more flows, or a self-contained element within a flow itself. A “flow” generally refers to related packets that are received, transmitted, or exchanged within a communication session. For convenience, a packet broadly refers to a series of bits or bytes having a prescribed format. Further, a data element may correspond to a collection of data that may take the form of an individual or a number of packets carrying related payloads, e.g., a single webpage received over a network.
As a self-contained element, the data element may be an executable (e.g., an application, program, segment of code, dynamically link library “dll”, etc.) or a non-executable. Examples of non-executables may include a document (e.g., a Portable Document Format “PDF” document, Microsoft® Office® document, Microsoft® Excel® spreadsheet, etc.), an electronic mail (email), downloaded web page, a file retrieved from a storage location over an interconnect, or the like.
The term “electronic device” should be generally construed as electronics with data processing capability and/or a capability of connecting to any type of network, such as a public network (e.g., Internet), a private network (e.g., a wireless data telecommunication network, a local area network “LAN”, etc.), or a combination of networks. Examples of an electronic device may include, but are not limited or restricted to, the following: a security appliance that includes any system or subsystem configured to perform functions associated with malware detection on an incoming object; a server, a mainframe, a firewall, a router; or an endpoint device (e.g., a laptop, a smartphone, a tablet, a desktop computer, a netbook, a medical device, or any general-purpose or special-purpose, user-controlled electronic device).
According to one embodiment, the term “malware” may be broadly construed as any content (e.g., code, data, command(s), etc.) or activity that initiates a malicious attack and/or operations associated with anomalous or unwanted behavior. For instance, malware may correspond to a type of malicious computer code intended to harm or co-opt operation of an electronic device or misappropriate, modify or delete data. In the alternative, malware may correspond to an exploit itself, namely (i) content that attempts to take advantage of a vulnerability in software and/or (ii) an action by a person gaining unauthorized access to one or more areas of an electronic device, where the exploit causes the electronic device to experience undesirable or anomalous behaviors. The undesirable or anomalous behaviors may include a communication-based anomaly or an execution-based anomaly which, for example, could (1) alter the functionality of an electronic device in an atypical manner or (2) provide unwanted functionality which may be generally acceptable in another context (e.g., uploading a contact list to cloud storage, but this upload is without receiving permission from the user).
The term “interconnect” may be construed as a physical or logical communication path between two or more electronic devices or between different logic (engine/components). For instance, a physical communication path may include wired or wireless transmission mediums. Examples of wired transmission mediums and wireless transmission mediums may include electrical wiring, optical fiber, cable, bus trace, a radio unit that supports radio frequency (RF) signaling, or any other wired/wireless signal transfer mechanism. A logical communication path may include an inter-process communication (IPC) mechanism that allows for the exchange of content between different logic.
The term “computerized” generally represents that any corresponding operations are conducted by hardware in combination with software or firmware.
The term “plug-in” may be broadly construed as a software component that adds a specific feature or features to another computer program, which is intended to include add-ins, add-ons, or extensions as well. In other words, the operation of a computer program can be altered or customized through incorporation of select individual plug-ins. Typically, a computer program is designed to support plug-ins. Various types of plug-ins, for example, are available for use in popular web browsers to add features such as search-engines, virus scanners, or the ability to open a previously unsupported file type.
Lastly, the terms “or” and “and/or” as used herein are to be interpreted as inclusive or meaning any one or any combination. Therefore, “A, B or C” or “A, B and/or C” mean “any of the following: A; B; C; A and B; A and C; B and C; A, B and C.” An exception to this definition will occur only when a combination of elements, functions, steps or acts are in some way inherently mutually exclusive.

Herein, the electronic device 100 comprises one or more hardware processors (referred to as “processor(s)”) 110, a memory 120, one or more network interfaces (referred to as “network interface(s)”) 130, and one or more network devices (referred to as “network device(s)”) 140 connected by a system interconnect 150, such as a bus. These components are at least partially encased in a housing 160, which is made entirely or partially of a rigid material (e.g., hardened plastic, metal, glass, composite, or any combination thereof) that protects these components from environmental conditions.
The processor(s) 110 is a multipurpose, programmable component that accepts digital data as input, processes the input data according to stored instructions, and provides results as output. One example of a processor may include an Intel® ×86 central processing unit (CPU) with an instruction set architecture. Alternatively, a processor may include another type of CPU, a digital signal processor (DSP), an Application Specific Integrated Circuit (ASIC), a field-programmable gate array (FPGA), or the like. The processor(s) 110 and operating system (“OS”) 185 within memory 120 operate as system resources for virtualized hardware that may control operability of one or more virtual machines operating with a dynamic analysis engine, described below.
The network device(s) 140 may include various input/output (I/O) or peripheral devices, such as a keyboard, key pad, touch screen, or mouse for example. Each network interface 130 may include one or more network ports containing the mechanical, electrical and/or signaling circuitry needed to connect the electronic device 100 to a network to thereby facilitate communications to other remotely located electronic devices. To that end, the network interface(s) 130 may be configured to transmit and/or receive messages using a variety of communication protocols including, inter alia, Transmission Control Protocol/Internet Protocol (TCP/IP), Hypertext Transfer Protocol (HTTP), or HTTP Secure (HTTPS).
The memory 120 operates as system memory, provided by non-persistent storage or persistent storage. From a logical perspective, the memory 120 includes a plurality of locations that are addressable by the processor(s) 110 and the network interface(s) 130 for storing logic, including a first analysis engine 170 and a second analysis engine 175. When deployed, the first analysis engine 170 performs a static analysis of a selected object by analyzing its characteristics. The second analysis engine 175 conducts a more in-depth analysis of the object through the use of one or more virtual machines 1801-180N (N≥1), which may be configured in accordance with a selected multi-app, multi-plugin processing framework.
Although not shown, the application/plug-in combinations of the multi-app, multi-plugin processing framework are set based, at least in part, on the type of object being processed. While a virtual machine (e.g., virtual machine 1801) is running, the suspicious object is processed concurrently by the application/plug-in combinations and the behaviors of each application/plug-in combination are monitored for analysis. An optional virtual machine monitor (sometimes referred to as a “VMM” or a “hypervisor”) 190 may be stored within memory 120 as well.

For this illustrative embodiment, however, the interface 220 may be configured to capture the object 224 for analysis, and perhaps its corresponding metadata (or generate metadata based on the captured object 224). According to one embodiment of the disclosure, the metadata may be used, at least in part by formatting logic 230, to determine protocols, application types and other information that may be used by logic within the threat detection system 200, such as a scheduler 235 or other logic such as a VMM (not shown), to determine a particular software profile used for virtual machine (VM) configuration and/or VM operation scheduling. As an example, one or more software profiles may be used for initial configuration of guest software of one or more VMs 1801-180N operating within dynamic analysis engine 175. Fetched from a storage device 240, these software profile(s) may be directed to different OS/ServicePacks, where different stored applications (e.g., different versions of the same application type, different application types, etc.), and/or different plug-ins (e.g., different versions of the same plug-in, different plug-in types, etc.) may be provisioned differently within each VM 1801-180N. Logic (launcher) within each VM 1801, . . . , or 180N may reconfigure the run-time operations to support a selected multi-app, multi-plugin analysis, as described below.
As further shown in

It is contemplated that the static analysis engine 170 may further include processing circuitry (not shown) that is responsible for extracting or generating metadata contained within or otherwise associated with formatted object 226 from the formatting logic 230 (e.g., network traffic, downloaded data). This metadata may be subsequently used by the scheduler 235 for initial configuration of one or more VMs 1801-180N within the dynamic analysis engine 175, which conducts run-time processing of at least some of the information associated with the formatted object 226.
Although not shown, for a multiple VM deployment, a first VM 1801 and a second VM 1802 may be configured to run concurrently, where each of these VMs may be initially configured with different software profiles. As an alternative embodiment, the first VM 1801 may be configured to run multiple application instances concurrently or sequentially (e.g., configuration data 265 imposing prescribed run-time delays), each application instance configured according to a selected application/plug-in combination. One of the application/plug-in combinations is selected to mimic an anticipated operating environment supported by one or more electronic devices targeted to receive the incoming data 222. One or more of these VMs, such as the first VM 1801 for example, includes logic that is adapted, during run-time, to configure a multi-app, multi-plugin processing framework with at least the application/plug-in combination that mimics the anticipated operating environment. The multi-app, multi-plugin processing framework may be dynamically configured based on the type of object being analyzed and on the contents of configuration data 265.
More specifically, after analysis of the formatted object 226 has been completed, the static analysis engine 170 may provide at least some of the information associated with the formatted object 226 (hereinafter generally referred to as “suspicious object” 228) to the dynamic analysis engine 175 for in-depth dynamic analysis by the VMs 1801-180N. For instance, according to one embodiment of the disclosure, a first VM 1801 may be adapted to conduct a multi-app, multi-plugin analysis, where the suspicious object 228 is a file path and is analyzed in accordance with a selected multi-app, multi-plugin processing framework. The multi-app, multi-plugin processing framework selects a software profile based, at least in part, on (i) the type of object being analyzed (e.g., certain type of data elements such as a PDF document or Microsoft® Office® document, a URL, etc.) and (ii) configuration data 265 including one or more priority lists that identify a prescribed order of execution on an plug-in basis and/or an application basis as shown in
According to one embodiment of the disclosure, the dynamic analysis engine 175 features one or more VMs 1801-180N, where each VM 1801, . . . , or 180N processes the suspicious object 228 within a run-time environment. For instance, as an optional feature, the dynamic analysis engine 175 may include processing logic 270 that is configured to provide anticipated signaling to the VM 1801-180N during processing of the suspicious object 228, and as such, emulates a source of or destination for communications with the suspicious object 228 while processed within that VM 1801, . . . , or 180N. As an example, the processing logic 270 may be adapted to operate by providing simulated key inputs from a keyboard, keypad or touch screen or providing certain signaling, as requested by the suspicious object 228 during run-time.
As shown in
According to one embodiment of the disclosure, the classification engine 250 is configured to receive the SA-based results 280 and/or the VM-based results 285. Based at least partially on the SA-based results 280 and/or VM-based results 285, the classification engine 250 evaluates the characteristic(s) within the SA-based results 280 and/or the monitored behaviors associated with the VM-based results 285 to determine whether the suspicious object 228 should be classified as “malicious”. The engine may receive one or more features as input, either individually or as a pattern of two or more features, and produces a result that may be used to identify whether the suspicious object 228 is associated with a malicious attack. The evaluation may be based on data acquired through experiential knowledge or machine learning.
For instance, the classification engine 250 may conduct a probabilistic modeling process that assigns risk levels to different monitored behaviors of the suspicious object 228 being processed within at least a first VM 1801 operating in accordance with multi-app, multi-plugin processing framework. The risk levels may be aggregated to produce a value (e.g., a probability score or risk designation) that denotes whether the suspicious content 228 is malicious (i.e. associated with an exploit attack). Upon determining that the content 228 is associated with a malicious attack, the classification engine 250 may provide information 290 to identify the malicious object, including information that identifies one or more of the monitored activities, to the reporting engine 260.
Furthermore, a detected malicious attack may be classified based on its associated application, plugin combination. Such classification may assist in identifying vulnerabilities currently be exploited for certain application, plug-ins or application/plug-in combinations. The same is true where OS/application or OS/application/plugin combinations are being supported by the multi-app, multi-plugin processing framework.
The reporting engine 260 is configured to receive information 290 from the classification engine 250 and generate alert signals 292, especially in response to the suspicious object 226 being now classified as malicious. The alert signals 292 may include various types of messages, which may include text messages, email messages, video or audio stream, or other types of information over a wired or wireless communication path. The reporting engine 260 features an optional user interface (e.g., touch pad, keyed inputs, etc.) for customization as to the reporting configuration.

According to one embodiment of the disclosure, the correlation logic 300 is communicatively coupled to the scheduler 235 of
In response to categorizing the suspicious object 228 as a URL type, the correlation logic 300 provides the suspicious (URL) object 228 and one or more parameters 310 to assist the launcher logic 350 in selecting a particular browser application (e.g., Internet Explorer, FireFox®, Chrome®, etc.) as part of the multi-app, multi-plugin processing framework 370. These parameters 310 may include, but are not limited or restricted to one or more of the following: (1) information that identifies the browser application type and version number when available (hereinafter “object type parameter 312”); (2) information to indicate whether the particular web browser type (and version number when available) has been pre-launched (hereinafter “pre-launch parameter 314”); (3) information to indicate whether plug-in switching functionality in the launcher logic 350 should be disabled in response to the malicious attack being solely based on the application type (hereinafter “plug-in switch parameter 316”); and/or (4) an identification of one or more plug-ins that are currently associated with (supported by) the browser application type identified in the object type parameter 312 (hereinafter “plug-in parameter(s) 318”).
In the event that browser application type (or version number) is not available to the scheduler 235, it is contemplated that the correlation logic 300 may be configured to analyze the suspicious object 228, and based on such analysis, categorize the suspicious object 228. For example, the correlation logic 300 may analyze the content of the suspicious object 228 and categorize the suspicious object 228 as a URL type based on for the presence of a “scheme” and/or “path” portion. The “scheme” includes a sequence of alphanumeric characters followed by a colon (:), where examples of schemes include “http”, “https”, “ftp”, or the like. The “path” contains data, usually organized in hierarchical form, which appears as a sequence of alphanumeric characters separated by slashes (/). Thereafter, the correlation logic 300 associates the suspicious object 228 with information representing a default browser application type that may be provided as the object type parameter 312 to the launcher logic 350.
Likewise, the correlation logic 300 may be configured to categorize the suspicious object 228 as a data type based on receipt of the file extension (e.g., .pdf, .doc, .docx, etc.) associated with the suspicious object 228 from the scheduler 235 or an analysis of the content of the suspicious object 228 for a file extension. In response to determining that the suspicious content 228 corresponds to a particular data type, the correlation logic 300 provides the object file path 320 to the suspicious object 228 stored locally and one or more parameters 330 to assist the launcher logic 350 in selecting a particular type of application (e.g., PDF reader, version of Microsoft Office®, etc.) as part of the multi-app, multi-plugin processing framework 370. For instance, one of these parameters 330 may include an object type parameter 332 that identifies a determined category of the object (e.g., Winword®; PDF, etc.). The object type parameter 332 may be referenced by the launcher logic 350 to select appropriate applications from priority list(s) within the configuration data 265 (described below).
Another parameter may include a pre-launch parameter 334, which is information identifying any applications corresponding the object type parameter 332 which have been pre-launched (e.g., Windows® Office® in a certain version, Windows® Office® in another version; Adobe® Acrobat® reader, Foxit® PDF reader, etc.). Applications can be pre-launched to take advantage of memory sharing among multiple VMs. Yet another parameter may include a plug-in switch parameter 336 that is used to enable or disable plug-in switching functionality in the launcher logic 350. The plug-in switching functionality is enabled when it is unclear whether a potential malicious attack may be directed to an application or plug-in while the plug-in switching functionality may be disabled when the malicious attack is solely directed to a particular application or plug-in in order to optimize performance of the first VM 1801. Lastly, another parameter includes the plug-in parameter(s) 338, which identifies one or more plug-ins that are currently associated with this data type.

It is contemplated that the prescribed configuration scheme is designed to provide a more robust VM-based analysis by processing the suspicious object 228 using a variety of different application/plug-in combinations. These application/plug-in combinations are selected to increase the likelihood in detecting (1) whether the object includes malware (analysis using application/plug-in combination(s) that may be more vulnerable to malicious attack or currently targeted by malware), (2) whether a targeted electronic device is susceptible to a malicious attack (analysis using application/plug-in combination(s) that represent the operating environment of the targeted destination for the suspicious object 228), and/or (3) whether the malicious attack corresponds to a zero day attack (analysis using the most fortified application/plug-in combination(s) to determine whether the suspicious object 228 is conducting anomalous behaviors that signify that the object is associated with a previously unknown malicious attack).
As an illustrative example, the configuration scheme may be directed for configuring a first application/plug-in combination 372 for the multi-app, multi-plugin processing framework 370 in accordance with the particular operating environment in which the suspicious object 228 is intended to be processed (e.g., application/plug-in version of an electronic device targeted to receive the object; most common application/plug version for a targeted enterprise; etc.). Thereafter, a second application/plug-in combination 374 for the multi-app, multi-plugin processing framework 370 may be configured based on which application/plug-in combination is currently found to be susceptible to a malicious attack (e.g., the least recent available version of the application (i.e., available within or for download to the threat detection system) along with the least recent plug-in version; any legacy (other than most recent) version of the application along with legacy versions of one or more plug-ins that are currently being attacked more frequently than other combinations based on research provided from machine learning or external resources such as forensic or third-party analysis). A third application/plug-in combination 376 may be configured in accordance with the most fortified application/plug-in combination (e.g., the most recent available version of the application along with the most recent plug-in version) for use in zero-day detection.
As shown in
Alternatively, as shown in
Herein, the priority scheme for the ordering of the applications 4101-410M may be dependent on one or more factors including, but not limited or restricted to prioritizing applications that are currently determined, on a selected basis (e.g., per customer, per multi-customer, per industry, per region, or per country basis), to be more frequency targeted for malicious attack than other applications of the same category type. Another priority scheme may be based on application release date or the popularity of certain versions of the applications being deployed within devices routinely connected to an enterprise network that is being monitored by the threat detection system 200 of
Similarly, as shown in
As an alternative embodiment, as shown in

Additionally, the launcher logic 350 may set the second application/plug-in combination 374 for the multi-app, multi-plugin processing framework 370 by accessing content with the application listing 400 to determine whether the application currently found to be susceptible to a malicious attack (which may be positioned at a predetermined location within the application listing 400 or associated with a predetermined priority designation), has not already been used as part of the multi-app, multi-plugin processing framework 370 for processing the object. If not, the application and corresponding plug-ins are selected. However, if the application has already been used in an application/plug-in combination that is part of the multi-app, multi-plugin processing framework 370, the next lower priority version of the application is selected along with the plug-ins having the highest priority that have been identified for that application.
Subsequently or concurrent to these operations, the launcher logic 350 may set the third application/plug-in combination 376 for the multi-app, multi-plugin processing framework 370 by accessing content with the application listing 400 to determine whether the most fortified application (e.g., most recent version of the application and corresponding plug-ins) has been used in the multi-app, multi-plugin processing framework 370. If not, that application and corresponding plug-ins are selected. However, if the application has already been used, the next lower version of the application is selected along with the plug-ins identified for that application as having the highest priority.
Thereafter, the suspicious object 228 is processed by the multi-app, multi-plugin processing framework 370 and behaviors of the each of these application/plug-in combinations is monitored. For the situation where the object is a URL being processed by different versions of a specific browser application and certain anomalous behaviors are being detected, the correlation logic 300 may signal the launcher logic 350 to formulate another multi-app, multi-plugin processing instance for a different browser application type.
As stated above, the processing of the suspicious object 228 may be halted when sufficient indicators are observed, so that VM analysis time can be conserved. Stated differently, the multi-app, multi-plug-in analysis can change course depending on the object behavior and analysis results (e.g., stop analysis after certain suspicious behaviors have been detected, use another application type after certain behaviors have been detected or after a prescribed time has elapsed for this analysis, etc.).
Referring to
The object-launching logic 530 is responsible for configuration of the multi-app, multi-plugin processing framework 370 by initially determining a first application and version that would likely correspond to an application running within an operating environment targeted by the suspicious object 228. Herein, based on the pre-launched parameter 314/334 provided by the correlation logic 300, the object-launching logic 530 initially determines whether the first application is pre-launched. If so, the object-launching logic 530 queries the pre-launched application identifier logic 550 for a handle corresponding to the pre-launched (first) application. The handle is used by the object launching logic 530 to open the object 228.
In response to the pre-launched application identifier logic 550 being unable to return a handle associated with the first application, which has been identified as being pre-launched by the object-application mapping table 510, an error condition exists. During this error condition, a default application corresponding to the object type is used along with default plug-ins. Plug-in switching logic 570 may be temporarily disabled as no plug-in switching is to occur during the error condition.
In response to the pre-launched application identifier logic 550 returning the handle associated with the first (pre-launched) application and plug-in multiplexing not being disabled that is signaled by content in the plug-in switch parameter provided by the correlation logic 500, the object launching logic 530 checks if the plug-in parameter(s) 318 or 338 is provided. If the plug-in type(s) and version(s) is(are) provided in the priority list 340, the object launching logic 530 may instruct the plug-in switching logic 570 to set the OS setting to use the identified plug-in type(s) and version(s). However if no plug-in parameter(s) 318/338 is provided or no matching plug-in versions are found in priority list 340, the object launching logic 530 selects a plug-in or a series of plug-ins based on the returned application type, such as the highest priority plug-ins for the returned application type.
Prior to launching the first (pre-launched) application by passing a command with the returned handle and the object to the first (pre-launched) application using the IPC mechanism, the object-launching logic 530 may communicate with the guest OS to alter plug-in system settings to register the plug-ins with the OS (e.g., into a Windows® registry for a Windows® OS or into p-lists for an iOS® deployment). Such registration may include altering the services names assigned to these plug-ins and maintaining the altered service names and/or setting appropriate registry values and/or changes to file system entities for the plug-ins.
In response to the pre-launched parameter 314/334 identifying that the first application (hereinafter “Application1_v1”) is not pre-launched, the object launching logic 530 accesses the priority list 340 to select an application/plug-in combination for processing the object 228 in accordance with a targeted operating environment. The targeted object environment may be determined based on an external parameter provided with the object 228. After the plug-in(s) are selected, the object launching logic 530 communicates with the guest OS to alter system settings to register altered services names assigned to these plug-ins with the OS (e.g., into the Windows® registry for a Windows® OS or into p-lists for an iOS®). Thereafter, the object launching logic 530 starts the first application/plug-in combination 372 using a launch process (e.g., CreateProcess( ), ShellExecute, etc.) in which the object 228 (URL or path to the file or document) is passed to the first application 372 (Application1_v1) to launch this application/plug-in combination.
Concurrently or subsequent to the launching of the first application/plug-in combination 372, the object launching logic 530 accesses the priority list 340 to select the second application/plug-in combination 374 for processing the object in accordance with a selected configuration scheme. As an example, as shown, the priority list 340 identifies in the application listing that a second version of the first application is currently found to be susceptible to malicious attack. The second version of the first application (hereinafter, “Application1_v2”) supports two plug-ins where “plug-in1_v2” and “plug-in2_v2”) are assigned the highest priority for suggested use as part of the multi-app, multi-plugin processing framework 370.
Thereafter, the object launching logic 530 accesses the pre-launched application identifier logic 550 for a handle corresponding to the second application. In response to the pre-launched application identifier logic 550 being unable to return a handle associated with the second application where the second application is not pre-launched, the object launching logic 530 may communicate with the OS to alter the system settings to register altered services names assigned to plug-in1_v2 and plug-in2_v2 and initiate a CreateProcess( ) or ShellExecute( ) in which the object (URL or path to the file or document) is passed to the second application (Application1_v2) to launch the application/plug-in combination.
Concurrently or subsequent to the launching of the first or second application/plug-in combination, the object launching logic 550 accesses the priority list 340 to select the third application/plug-in combination 376 for processing the object in accordance with the selected configuration scheme. For instance, as shown, the most fortified (or most recently released) application within the application listing of the priority list 340, namely a third version of the first application, is determined. The third version of the first application (hereinafter, “Application1_v3”) supports a single plug-in “plug-in1_v3” as the third version of the application may not support functionality offered by the second plug-in type (“plug-in2”).
Thereafter, the object launching logic 530 accesses the pre-launched application identifier logic 550 for a handle corresponding to the third application. In response to the pre-launched application identifier logic 550 being unable to return a handle associated with the third application, as described above, the object launching logic 530 may communicate with the OS to alter plug-in system settings to register altered services names assigned to plug-in1_v3 and initiates a CreateProcess( ) or ShellExecute process in which the object (URL or path to the file or document) is passed to the third application (Application1_v3 376) to launch the application/plug-in combination.
The same operations are conducted for launching the second application group 378 that is part of the multi-app, multi-plugin processing framework 370, including a first version of the second application (Application2_v1) and a second version of the second application (Application2_v2).
It is contemplated that, during monitoring of the behaviors of the application/plug-in combinations 372, 374, 376, 378 during processing of the suspicious object 228, certain types of anomalous behaviors may signal the correlation logic 300 to notify the launcher logic 350 to discontinue launching any additional application/plug-in combinations as the multi-app, multi-plugin analysis may already conclude that the suspicious object 228 is associated with a malicious attack or is clearly benign.
Likewise, it is contemplated that, during monitoring of the behaviors of the application/plug-in combinations 372, 374, 376, 378 during processing of the suspicious object 228, certain types of anomalous behaviors may signal the correlation logic 300 to notify the launcher logic 350 to generate a new multi-app, multi-plugin processing framework using a different application type. For instance, a current multi-app, multi-plugin processing framework may be based on a first type of application, where a secondary analysis conducted by a new multi-app, multi-plugin processing framework based on a second type of application that is different from the first type of application. This secondary analysis is conducted to confirm the finding of malware that is not isolated to a certain application or plug-in type.
Referring to
Thereafter, a determination is made as to whether the application selected for launching as part of the multi-app, multi-plugin processing is pre-launched (block 615). If so, a handle associated with the pre-launched application is obtained by the launcher logic (blocks 620 and 625). Otherwise, the application selected for launching will need to be launched through a launching application.
Prior to launching the selected application, a determination is made as to whether plug-in switching has been disabled (block 630). If so, the default plug-ins for the particular application type is selected (block 635). Otherwise, the plug-in listings of the priority list that correspond to the selected application are read and plug-in system settings in the OS are set so that these plug-ins are loaded with the launching of the selected application (blocks 640, 645 and 650).
Thereafter, the priority list is accessed to select application/plug-in combinations based on the configuration scheme selected for the multi-app, multi-plugin processing framework (block 655). This process is iterative for additional data elements received for malware analysis.
Referring to
However, if the browser application (and version) can be determined, a first determination is made as to whether the browser application selected for launching as part of the multi-app, multi-plugin processing is pre-launched (block 715). If so, a second determination is made as to whether the handle for the pre-launched browser application can be retrieved (block 720). If not, an error condition has occurred and the analysis completes (path 725). If the handle can be retrieved, the handle associated with the pre-launched browser application is obtained by the launcher logic (block 730). If the selected browser application is not pre-launched, the configuration data (priority list) is read to identify the best match for the first application type (block 735).
Prior to launching the selected application, a determination is made as to whether plug-in switching has been disabled (block 740). If so, the default plug-ins for the particular application type is selected (block 745). Otherwise, the plug-in listings of the priority list that correspond to the selected browser application are read and plug-in system settings in the OS are set so that these plug-ins are loaded with the launching of the selected application (blocks 750, 755 and 760).
Thereafter, the priority list is accessed to select application/plug-in combinations based on the configuration scheme selected for the multi-app, multi-plugin processing framework (block 765). This process is iterative for additional URLs received for malware analysis.
In the foregoing description, the invention is described with reference to specific exemplary embodiments thereof. It will, however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope of the invention as set forth in the appended claims.
