Bugbear, also known as Tanatos, doesn't destroy files like its viral cousins "Melissa," "Michelangelo" and "Iloveyou." Instead, it disables popular firewall and anti-virus protections and prepares a port that can receive instructions from remote users.
That is what makes the virus so dangerous, experts say. Hackers aware of this vulnerability will search for open ports on infected computers. Once found, attackers can access passwords, view or destroy data and get reports of keystrokes being entered – including credit card numbers and other sensitive information. All of this happens without the knowledge of the hacked computer owner or business.
