MyDoom.BQ/Mytob.ED opens backdoor IRC channel
Security experts have warned of a newly intercepted worm spreading throughout Europe which allows hackers to take remote control of infected PCs.
MyDoom.BQ, also known as Mytob.ED, arrives as an attachment in an email claiming that the user's email system has been "locked" for security reasons.
Once the attachment is opened the worm harvests email addresses to send itself on, and installs a backdoor channel to IRC that allows remote control of the PC.
