Fortinet protects against latest MyDoom variant

  • 15 November, 2004 09:12

<p>SYDNEY – November 15, 2004 – Fortinet – the confirmed market leader in Unified Threat Management and only provider of ASIC-accelerated, network-based antivirus firewall systems for real-time network protection – today announced that its FortiGate™ systems protect against the latest MyDoom worm variant, W32/Mydoom.AH-mm, also known as Bofra B.</p>
<p>The latest MyDoom variant, which is similar to the previous MyDoom worm named W32/Mydoom.AG-mm and also known as W32/Bofra.C, uses the same infection vector targeting pre-Windows XP Service Pack 2 machines, including machines running general Microsoft Windows and systems offering TCP services.</p>
<p>W32/Mydoom.AH-mm is a mass-mailing worm that implements a Microsoft Internet Explorer IFRAME buffer overflow vulnerability. The worm sends an email to targets, including a hyperlink to the infected system. If recipients of the message follow the hyperlink, the infected system then delivers exploited HTML content, downloads a copy of the virus to the target’s machine and runs the virus. Fortinet currently rates the latest MyDoom variant a Level One worm, but notes it has the potential to be a higher threat in the future.</p>
<p>Fortinet issued the following new signatures to help block the buffer overflow by the latest MyDoom variant:
103022610 IE.IFRAME.BufferOverflow.A
103022611 IE.IFRAME.BufferOverflow.B
103022612 IE.IFRAME.BufferOverflow.C
103022613 IE.IFRAME.BufferOverflow.D</p>
