BSE Trojan

The author of this virus is a German hacker called BSE. It was written
in Assembler applicationming language. The origination date is February
2000. It affects Windows 95/98/ME/NT/2000 computers. The principle of
such application is simple: the attacker infects his victim via the e-mail
or File and Print Sharing with a server application. Once in the computer,
the virus opens a default port TCP 25 and awaits commands from the
intruder. He can connect to the infected PC via a client application.
However this virus can not be classified as danreroius, because the
server is visible.
