Security company BitDefender reports a new threat, dubbed Trojan.Spammer.HotLan.A, using automatically generated Yahoo and Hotmail accounts to send out spam email.
“There are only about 500 or so new accounts being created every hour,” commented head of BitDefender Antivirus Lab Viorel Canja. “But still, we’ve seen 15,000+ Hotmail accounts being used so far. It’s hard to estimate how many spam e-mails have already been sent.”
