Virus writers deploy bulk mail software
Hackers have used spamming software to distribute thousands of copies of a new Trojan. Email filtering firm MessageLabs alone has intercepted more than 4,000 copies of the Demonize-T Trojan over the last 24 hours. Demonize-T is a multi-stage Trojan that uses an object data exploit in Internet Explorer (patch here) to download and execute an encoded visual basic script from a website. The Trojan then creates an executable file which appears to download a malicious program from the same website as the original script. Early analysis suggests Demonize-T is similar to previous attacks where malicious code has been used to install key loggers and password stealers. Spammers are increasingly using infected as a platform to distribute spam and this technique has come full circle with virus writers using spam to infect machines in the first place. Full Story
