The whole earth has been corrupted through the works that were taught by Azazel: to him ascribe all sin. -- 1 Enoch 2:8
Azazel is a userland rootkit based off of the original LD_PRELOAD technique from Jynx rootkit. It is more robust and has additional features, and focuses heavily around anti-debugging and anti-detection.
- Anti-debugging
- Avoids unhide, lsof, ps, ldd detection
- Hides files and directories
- Hides remote connections
- Hides processes
- Hides logins
- PCAP hooks avoids local sniffing
- Two accept backdoors.
- Crypthook encrypted accept() backdoor -- Full PTY
- Plaintext accept() backdoor -- Full PTY
- PAM backdoor for local privesc and remote entry
- Log cleanup for utmp/wtmp entries based on pty
Using netcat to communicate with a remote PTY isn't the best idea. See below for a better PTY client written by InfoDox, or use socat with a command similar to the following and then just paste the password into the session, otherwise socat send the first char making the passwords not match.
socat -,raw,echo=0 TCP:target:port,bind=:61040
