-----BEGIN PGP SIGNED MESSAGE----- Internet Security Systems Security Brief August 1, 2003 "Mimail" Mass-Email Worm Propagation Synopsis: ISS X-Force has detected the spread of a mass-emailing worm named "Mimail". The Mimail worm is currently propagating aggressively across the Internet. Mimail takes advantage of a vulnerability in Internet Explorer to hide an executable program within what appears to be a benign HTML file delivered to recipients via email. Impact: The executable payload of the worm is hidden within a HTML file that is delivered in a compressed ZIP archive. Many Internet users believe that HTML files are not dangerous. The Mimail worm was designed specifically to appear to be benign, and to execute via a flaw in Internet Explorer. Viruses or worms that propagate by exploiting flaws in software are particularly dangerous, and they generally propagate more effectively.
