Portal of Doom
Portal of Doom (abbreviated as PoD and sometimes spelled all one word, as PortalOfDoom) is a Trojan horse that hijacks the computers of unsuspecting Windows users running old operating systems. Computers running Windows 95, 98, ME, NT, XP and Vista are vulnerable to the Trojan.
PoD affords the attacker near-complete remote control of the target system. The Trojan enters through a back door on vulnerable machines, typically through TCP ports 9872-9875 and UDP ports 10067, 10167. Port 9875, in particular, is notorious for being exploited by this malware and as a result is sometimes referred to as the Port of Doom.
The Trojan launches from the registry key HKLM\Software\Microsoft\Windows\CurrentVersion\Run. Portal of Doom can enter without causing any behavior that alerts the user and does not have to trick the user into running an executable file manually. It typically installs to C:\windows\system and its running process names can vary.
Malicious hackers can use PoD to look for sensitive data, such as credit card numbers and information that enables identity theft, or just to cause mischief. PoD was written in MS Visual Basic.
