Problems with Syscall Proxies

Conclusion

In this chapter, you learned how to do a runtime patch via shellcode. Instead of creating simple connect-back shellcode, which can be easy for an IDS to discover, subtle runtime patching makes an excellent stealth attack on a penetration test. We also covered the concept of syscall proxies in great detail, because most shellcode will likely be implemented in syscall proxies in the future.
