Alex Hinchliffe, principal risk researcher at Unit 42, the risk intelligence and incident response arm at Palo Alto Networks, says, “Very primary or particular detection mechanisms, similar to hash-based scanners, are thwarted by polymorphism however it’s price noting that every time a bug is compiled — e.g., into an executable — it would yield a brand new distinctive fingerprint or hash. Add to this the plethora of free and commercially obtainable compressor, packer, and protector instruments, which might be utilized to a compiled program, and the ‘identical’ program will yield but extra variations and permutations of the identical fingerprint.”
Polymorphic malware additionally typically makes use of encryption to cover its payload, additional complicating detection and evaluation.
