Bagle Bites Back with New Variant

<p>Bagle Bites Back with New Variant
Bagle.BM already causing a 'serious outbreak' says Avalanche</p>
<p>Melbourne, Mar 1, 2005 – Avalanche Technology Group, authorised reseller for Grisoft and the AVG Anti-Virus family of software products in Australia &amp; New Zealand, says Grisoft Labs today detected another new variation of the Bagle worm:</p>
<p>Bagle.BM. This latest form of the Bagle computer virus is spreading rapidly and has already caused a serious outbreak.</p>
<p>As with previous versions of the virus, Bagle.BM is spreading via the Internet as an attachment to infected email messages. However, this time there is a subtle difference. Bagle.BM doesn’t spread itself but it’s spammed massively to email addresses previously acquired by spammers.</p>
<p>The worm itself is a Windows executable file of 34KB. It is attached to messages that come with an empty subject; body contains “new price” or just “price”.</p>
<p>When a user opens the attachment it activates the worm that, in turn, launches the infected file. The worm then copies itself to the Windows system directory, and registers this file in the system registry. Bagle.BM also terminates processes designed to protect the victim machine and the local network. This leaves the infected machine vulnerable to further attacks by malicious code.</p>
<p>“The new Bagle variant was discovered by our labs overnight,” says Peter Cameron, Director of Business Development at Avalanche. “Users of AVG should be reassured that we have already issued an emergency update that will protect their systems from this latest threat.</p>
<p>“With several months since the last major outbreak, it looks like we may be entering a new period of increased virus activity,” continued Cameron.</p>

<p>About AVG Anti-Virus
AVG Anti-Virus software shields computers from viruses, trojans horses and worms with a multi-layer approach that is more comprehensive than most protection programs. Following extensive pre-processing to scan data for patterns of virus code, AVG moves on to examine files using generic detection to root out new strains or variants of known viruses. Two levels of heuristic analysis are performed –
dynamic and static. The dynamic level uses code emulation to evaluate in a secure virtual environment the behaviour of the program or file being tested. Static heuristic analysis locates programming code associated with certain types of virus propagation. AVG then performs an integrity check. Certain data associated with each scanned file is stored in its internal integrity database and used to heal infected files, potentially restoring information, which may have been lost during infection. AVG supports all Windows operating systems, from Windows 95 through</p>
<p>the latest version of Windows XP, and provides users with extremely fast and efficient database updates to meet the latest viral threats.</p>
