Which of the following tools can be used to perform polymorphic shell code attacks?

ADMutate takes existing shellcode and applies polymorphic transformations, such as variable NOP sleds and encoded payloads, producing functionally equivalent but signature-different shellcode on each run. This technique is used to bypass IDS/IPS systems that rely on static shellcode signatures.

TrueCrypt is a full-disk and volume encryption utility with no capability to generate or mutate exploit shellcode.

Fragroute is a network packet fragmentation tool used to evade network-level inspection by splitting packets, not to generate polymorphic shellcode.

Mendax is not a recognized tool for polymorphic shellcode generation and is not associated with this attack category.
