ComputerWorld: New 'Cholera' virus spreads automatically

(Other stories by Matthew Nelson)

"A new combined worm and virus threat, called Cholera, has been posted to a hacker's Web site and has antivirus vendors scrambling to provide protection before an epidemic spreads akin to Melissa and Worm.ExploreZip."

"The worm/virus is currently listed as a medium threat, as it hasn't been found 'in the wild' infecting user systems, but will automatically be upgraded to a high threat as soon as it is..."

"Cholera is similar to Worm.ExploreZip as it unleashes a worm-style attack that will automatically send itself to any e-mail address it finds on an e-mail system, and therefore carries the potential to clog and shut down e-mail servers. Cholera is also not platform-dependent and can operate off of any e-mail system... At this time, Computer Associates is still investigating what payload, if any, the virus will deliver."

"The worm becomes resident when the infected system is rebooted. Once activated, the worm installs itself by adding keys to WIN.INI on Windows 9x and the registry on Windows NT. The worm will also try to copy itself to any shared drives to which the user is currently connected. Then it proceeds to infect executables in the directory from where it is launched with a virus named W32/CTX."

" 'It's sort of a dual thing because of the virus and worm aspect, so it's sort of screaming, 'Build a variant of me,' ' [CA antivirus product manager Narender] Mangalam said.' "
