Vulnerability: Authentication Bypass Empty Password
Description: ReverseTrojan by satan_addict listens on TCP ports, 12000 and 21. The malware accepts empty credentials for authentication as the default settings are set to blank. Third-party attackers who can reach an infected host can potentially gain access to the machine before or if no password is set.
