Subseven.21 is a backdoor type Trojan that allows hackers to gain remote access to the infected computer in order to carry out actions that can compromise the user’s confidentiality and impede the tasks performed on the computer.
The effects of Subseven.21 are the following: it opens or closes the CD-ROM tray, it moves the mouse pointer and opens chat servers.
This Trojan consists of two programs:
- Server, which is installed in the attacked computer.
- Client, which is installed in the attacker’s computer.
These programs are connected to one another through a port opened by the Trojan, which is TCP port 27374 by default.
An indication that Subseven.21 may have infected your computer is the mouse pointer moving for no apparent reason or the CD-ROM tray opening and closing without user intervention.
