Research on anti anti-virus technology based on Shellcode
Nan Wu, Yixi Li · 2023
With the development of the internet, enterprises and individuals pay more and more attention to network security. Various anti-virus software, active defense and other protection products have developed rapidly. It is not ideal to use traditional Anti Anti-virus technology. In this paper, we propose a Anti Anti-Virus (AAV) technology based on shellcode. First, generate shellcode using Cobalt Strike. Then, by using encryption obfuscation, sandbox evasion, API substitution call technologies, shellcode is encapsulated secondary. At last, compile it into executable file with Golang. Test the executable file on the local anti-virus software. At the same time, upload it to VirusTotal for multi-engine online testing. Testing results indicate that the executable file can run, and it is suitable for penetration testing in daily.
