GAQM Exam CPEH-001 Topic 1 Question 67 Discussion

ADMmutate is using a polymorphic technique designed to circumvent certain forms of signature based intrusion detection. All network based remote buffer overflow exploits have similarities in how they function. ADMmutate has the ability to emulate the protocol of the service the attacker is attempting to exploit. The data payload (sometimes referred to as an egg) contains the instructions the attacker wants to execute on the target machine. These eggs are generally interchangeable and can be utilized in many different buffer overflow exploits. ADMmutate uses several techniques to randomize the contents of the egg in any given buffer overflow exploit. This randomization effectively changes the content or 'signature' of the exploit without changing the functionality of the exploit.
