Defining Packers, Akamai’s post reads,
Software packing is a method of compressing or encrypting code that makes it unreadable or non-debuggable. As a result, the code changes in an attempt to avoid signature- or hash-based detection.
Certainly, packers aren’t a new thing; rather they previously caught attention in 2008 as well when researchers from Secureworks highlighted the “Packer 2.0” conundrum. Regarding the need for this technique, they stated in their post,
Detecting Packaged Malware
Although, malware obfuscation often effectively bypasses detection. However, Akamai researchers have devised how to detect obfuscated malware too.
It was through this profiling that they spotted 25% of malicious codes hidden via obfuscation. The researchers believe that this technique might facilitate in prompt detection of obfuscated malware in real-time.
