Vulnerability: Weak Hardcoded Credentials
Description: The malware listens on TCP ports 51966 and 23. Authentication is required, however the password "mama" is weak and found within the PE file. Moreover, the FTP server running on non standard port 23 also uses same password. Trying to execute a program incorrectly you get reply like, "STATUS I can't run program", as it requires the full path to the file to execute.
Vuln ID: MVID-2022-0617
C:>nc64.exe x.x.x.x 51966
Enter your password:
STATUS: unknown command "WHOAMI"
STATUS: program runned
