Trojan.Spammer.HotLan.A uses automatically generated email accounts,
suggesting that spammers have found a way to bypass so-called Captcha systems.
Captcha works by preventing new accounts being created until the creator
correctly identifies the letters depicted in an image.
Every active copy of the Trojan accesses an account, and pulls encrypted spam
emails from a website. It then decrypts the emails and sends them to valid
addresses taken from yet another website.
"There are only about 500 or so new accounts being created every hour," said
Viorel Canja, head of BitDefender's antivirus lab.
"But we have seen at least 15,000 Hotmail accounts being used so far. It is
hard to estimate how many spam emails have already been sent."
The spam currently being distributed attempts to lure users to a site
advertising pharmacy products. Common spam techniques are used in the email
body, such as random word generation and a random email subject.
