Frequently Asked Questions
What are anti-debugging techniques?
They are checks malware uses to detect that it is being debugged, such as reading the PEB BeingDebugged flag, measuring execution time or inspecting debug registers. When detected, the sample changes or stops its behaviour.
How does malware detect a virtual machine?
Malware looks for VM artefacts like specific drivers, registry keys, MAC address prefixes, low resources or CPU instruction behaviour. If it finds them, it may refuse to run so the sandbox sees nothing malicious.
Can anti-analysis checks be bypassed?
Yes. Analysts patch the checks, hook the relevant APIs or harden the analysis environment so the malware runs normally. This advanced room on Codelivly is free and shows these bypasses hands-on.
