W32.Mydoom.B@mm [Symantec-2004-012816-3647-99] (2004.01.28) - mass-mailing worm that opens a backdoor into the system. The backdoor makes use of TCP ports 80, 1080, 3128, 8080, and 10080.
W32.HLLW.Deadhat [Symantec-2004-020619-0805-99] (2004.02.06) - a worm with backdoor capabilities. It attempts to uninstall the W32.Mydoom.A@mm and W32.Mydoom.B@mm worms, and then it spreads to other systems infected with Mydoom. Also, it spreads through the Soulseek file-sharing program.
Multiple buffer overflows in Thomas Hauck Jana Server allow remote attackers to cause a denial of service and possibly execute arbitrary code via an HTTP GET request with a long major version number, an HTTP GET request to the HTTP proxy on port 3128 with a long major version number, a long OK reply from a POP3 server, and a long SMTP server response.

Trojan.Win32.SkynetRef.x / Unauthenticated Open Proxy - the malware listens on TCP port 3128. Third-party attackers who can connect to the infected system can relay requests from the original connection to the destination and then back to the origination system. Attackers may then be able to launch attacks, download files or port scan third party systems and it will appear as the attacks originated from that infected host.
