Which term describes techniques used to prevent dynamic analysis by fingerprinting the emulated system environment?

• A. Anti-goat
• B. Add-on viruses
• C. Persistent virus
• D. Anti-emulation

Answer: (D)

Techniques used to prevent dynamic analysis by fingerprinting the emulated system environment are called anti-emulation. Malware analysts often run samples in sandboxes or virtual machines to observe behavior, but some malware checks for signs it’s in such an environment. It might look for virtualization-related artifacts, odd timing, or other emulator indicators, and if detected, it changes its behavior or stays dormant to avoid revealing its payload. This deliberate evasion is what anti-emulation covers. The other options don’t fit this idea. Anti-goat isn’t a standard term in malware analysis; add-on viruses describe extra code appended to software, not techniques to evade analysis; and persistent viruses refer to how malware survives reboots, not to avoiding dynamic analysis through emulator detection.
