Today, I spoted on VirusTotal an interesting Python RAT. They are tons of them but this one attracted my attention based on some function names present in the code: self_modifying_wrapper(), decrypt_and_execute() and polymorph_code(). A polymorphic malware is a type of malware that has been developed to repeatedly mutate its appearance or signature files at every execution time. The file got a very low score of 2/64 on VT! (SHA256:7173e20e7ec217f6a1591f1fc9be6d0a4496d78615cc5ccdf7b9a3a37e3ecc3c).
