Trojan using webmail to send spam
Captcha systems possibly cracked to automate account creation.
BitDefender has reported a new trojan attempting to bypass security measures on leading webmail systems
Hotmail and Yahoo!, to use their services to send out spam.
The trojan, dubbed 'Spammer.HotLan', downloads instructions from the web, and then either logs into existing
accounts and mails from there, or tries to create new accounts to use. No details have yet emerged of how the
malware bypasses 'Captcha' systems, designed to ensure only human users can set up accounts.
