New spam trojan hits Hotmail and Yahoo
Hotmail and Yahoo accounts have been hijacked to send out tens of thousands of spam messages, according to security firm BitDefender.
The two webmail providers have fallen victim to a new trojan called Trojan.Spammer.HotLan.A.
The malware not only generates new webmail accounts automatically but has also found a way around the anti-spam CAPTCHA system, which requires people to enter the letters depicted in an image.
The trojan reportedly accesses the webmail account, pulls encrypted spam messages from another website, decrypts them and then sends them out to legitimate email addresses. The messages send users to a site selling pharmacy products.
