  • Detecting obfuscated malware variants
    Patent number: 11449609
    Abstract: A threat management facility analyzes a plurality of instructions in computer code for redundancy. When redundancy is found, the threat management facility determines whether the redundancy has characteristics of deliberate obfuscation consistent with malware techniques such as server-side polymorphism. Measures of redundancy, such as one or more of a degree of redundancy or a pattern of redundancy, may inform this process, and my usefully aid in distinguishing legitimate code redundancies from malware. Where an inference of malware is supported, the threat management facility may initiate remediation of the computer code. Further, or instead, the type of remediation applied to the computer code may be based on one or more aspects of the detected obfuscation.
