Threat: Backdoor.Win32.Prorat.lkt
Vulnerability: Port Bounce Scan (MITM)
Description: The ProSpy Server V1.9 malware runs an FTP component
that listens on TCP port 2121. 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.
