Panda Software, a leading international developer of computer security software, reported that W32/Bugbear reaches computers in an e-mail message which is very difficult to recognize. Bugbear randomly makes up the subject, contents and the name of the attached file. Cleverly disguising itself, it is hard for computer users to detect the worm, making computers easy targets for infection.
Additionally this is a malicious code designed to send itself out in a file attached to an e-mail message. The name of the attachment and the e-mail subject and message are variable. This opens the door to a hacker who could come in and take control of the computer and potentially cause unassailable damage.
According to Panda Software, W32/Bugbear takes advantage of a vulnerability found in MS Internet Explorer 5.01 and 5.5 SP-1 that allows files attached to an e-mail message to be automatically run.
None of Panda's Antivirus users have reported infection as Panda Antivirus subscribers are protected by daily signature file updates from Panda Software. In order to avoid infection, Panda Software recommends that computer users update their antivirus solutions immediately.
The multinational antivirus developer has already made the corresponding update for its antivirus available to computer users. This update, which detects and removes Bugbear, can be downloaded from Panda Software's Virus Encyclopedia at http://www.pandasecurity.com/default.htm.
The worm's main action consists of attacking files used by antivirus programs and firewalls. For in-depth reports on files affected by this worm go to: http://www.pandasecurity.com/default.htm.
