Bigorna Trojan

This spyware, which was written in 2001 in Brazil, is a really dangerous backdoor trojan, able to compromise the privacy of every user, who has no reliable defence installed on his or her PC. Bigorna Trojan acts by opening several certain ports and connecting to the Internet through them. In case of success, the connection between server and the hacker is established; this enables hacker to perform his or her destructive actions, such as stealing user's login information.
