Bubbel

Several versions appeared from January 2001 to February 2005. A Remote
Administration Tool is a special kind of hacker malware, used for
remote access and control of other people's PCs. The attacker
infects the PC via the e-mail or File and Print Sharing. A "server"
allows him to connect via a "client" on his own machine. The functions
of a RAT may vary, depending on the needs of the hacker. Some RATs
can't really harm your PC and the only purpose they were made for is
hooliganism. But some versions can steal vital information, remove
files and even crash your computer. You can find this pest in the
internet under such names as Bubbel
