Abstract

A computerized method for analyzing an object is disclosed. The computerized method includes obtaining, by a cybersecurity system, an object and context information generated during a first malware analysis of the object conducted prior to obtaining the object. Thereafter, the cybersecurity system performs a second malware analysis of the object to determine a verdict indicating maliciousness of the object. The scrutiny of the second malware analysis is adjusted based, at least in part, the context information, which may include (i) activating additional or different monitors, (ii) adjusting thresholds for determining maliciousness, or (iii) applying a modified rule set during the second malware analysis based on the context information.

Claims (28)

1. A computerized method for analyzing an object within an enterprise network, the method comprising:

obtaining, by a cybersecurity system, an object and first context information generated during a first malware analysis of the object conducted prior to obtaining the object; and

performing, by the cybersecurity system, a second malware analysis of the object to determine a verdict indicating maliciousness of the object, wherein a scrutiny of the second malware analysis is adjusted based at least in part by (i) activating additional or different monitors, (ii) adjusting thresholds for determining maliciousness, or (iii) applying a modified rule set during the second malware analysis based on the first context information,

wherein the second malware analysis is based at least in part on an origination of the object, the origination being a vector by which the object entered the enterprise network, and wherein the origination is determined by parsing the first context information for origination information associated with the origination of the object.

2. The computerized method of claim 1 , wherein prior to performing the second malware analysis, modifying a set of predetermined rules associated with the second malware analysis based at least in part on the first context information to produce the modified rule set.

3. The computerized method of claim 1 , wherein prior to performing the second malware analysis, activating the additional or different monitors by at least activating a particular set of process monitors based at least in part on the first context information.

4. The computerized method of claim 1 further comprising:

performing the first malware analysis of the object by a first cybersecurity system being a first network device, wherein the first malware analysis produces the first context information that includes at least the origination information of the object corresponding to a manner by which the object entered the enterprise network and additional information detailing performance of the first malware analysis.

5. The computerized method of claim 1 , wherein the first context information further includes a result of the first malware analysis, a hash of the object and one or more rules implicated during the first malware analysis.

6. The computerized method of claim 1 , wherein the object is a modified object including the first context information.

7. The computerized method of claim 6 , wherein the modified object is an email including a modified header of the email including the first context information, the modified object being provided to an agent on an endpoint conducting the second malware analysis of the modified object.

8. The computerized method of claim 4 further comprising:

uploading, by the first cybersecurity system, the first context information to a storage device communicatively coupled to the enterprise network; and

obtaining, by the second cybersecurity system, the first context information by causing a query to be transmitted to the storage device.

9. The computerized method of claim 1 , wherein the vector corresponds to information identifying a manner in which the object entered into the enterprise network.

10. The computerized method of claim 1 , wherein the performing of the second malware analysis is conducted based, at least in part, on an origination and object type of the object.

11. The computerized method of claim 9 , wherein the vector includes a mode of entry into the enterprise network including (i) email traffic, (ii) network traffic, or (iii) a removable storage device.

12. A non-transitory storage medium including software that, when executed, by a processor performs operations including analyzing an object within an enterprise network, comprising:

obtaining, by the processor, an object and first context information generated during a first malware analysis of the object conducted prior to obtaining the object; and

performing, by the processor, a second malware analysis of the object to determine a verdict indicating maliciousness of the object, wherein a scrutiny of the second malware analysis is adjusted based at least in part by (i) activating additional or different monitors, (ii) adjusting thresholds for determining maliciousness, or (iii) applying a modified rule set during the second malware analysis based on the first context information,

wherein the second malware analysis is based at least in part on an origination of the object, the origination being a vector by which the object entered the enterprise network, and wherein the origination is determined by parsing the first context information for origination information associated with the origination of the object.

13. The non-transitory storage medium of claim 12 , wherein the software, prior to performing the second malware analysis, conducts an operation of modifying a set of predetermined rules associated with the second malware analysis based at least in part on the first context information to produce the modified rule set.

14. The non-transitory storage medium of claim 12 , wherein the software, prior to performing the second malware analysis, conducts an operation of activating the additional or different monitors by at least activating a particular set of process monitors based at least in part on the first context information.

15. The non-transitory storage medium of claim 12 , wherein the software, upon execution by the processor, further obtains additional information detailing performance of the first malware analysis along with the origination information.

16. The non-transitory storage medium of claim 12 , wherein the first context information further includes a result of the first malware analysis, a hash of the object, and one or more rules implicated during the first malware analysis.

17. The non-transitory storage medium of claim 12 , wherein the obtained object is a modified object including the first context information.

18. The non-transitory storage medium of claim 17 , wherein the modified object is an email including a modified header of the email including the first context information, the modified object being provided to an agent on an endpoint conducting the second malware analysis of the modified object.

19. The non-transitory storage medium of claim 12 , wherein the vector corresponds to information identifying a manner in which the object entered into the enterprise network.
