Forensic Analysis Avoidance Techniques of Malware
Murray Brand · Australasian Journal of Paramedicine · 2007
Anti-forensic techniques are increasingly being used by malware writers to avoid detection and analysis of their malicious code. Penalties for writing malware could include termination of employment, fines or even, imprisonment. Malware writers are motivated not to get caught and are actively using subversive techniques to avoid forensic analysis. Techniques employed include obfuscation, anti-disassembly, encrypted and compressed data, data destruction and anti-debugging. Automated detection and classification work is progressing in this field. This includes analysing statistical structures such as assembly instructions, system calls, system dependence graphs and classification through machine learning.
