Anti-virus and pen-testing
Another good reason for obfuscating files or generating shellcode with ZSC is, that it can be used during your pen-testing. Malicious hackers use these techniques to bypass anti-virus and load malicious files in systems they have hacked.
Anti-virus work with signatures, in order to identify harmful files. When using very well known encoders such as msfvenom, files generated by this program might be already flagged by Anti-virus programs.
Our purpose is not to provide a way to bypass anti-virus, instead, we want to provide pen-testers a way to challenge the security provided by Anti-virus programs and Intrusion Detection systems during a pen test.In this way, they can verify the security just as a black-hat will do ;-).
