MyDoom and Bagle return once more

Users would be well advised to make sure their PC security is up to scratch as the latest anti-virus warning from MicroWorld Technologies is that the notorious MyDoom and Bagle worms have again reared their heads.

Users would be well advised to make sure their PC security is up to scratch as the latest anti-virus warning from MicroWorld Technologies, publisher of eScan and MailScan, is that the notorious MyDoom and Bagle worms have again reared their heads.

The latest MyDoom variant, known as MyDoom.N, spreads both through file-sharing P2P networks such as Kazaa and via infected attachments.

According to Govind Ramamurthy, managing director of MicroWorld Technologies, MyDoom.N worms have a built in SMTP engine (Small Mail Transfer Protocol), which allows the virus to send e-mails independently of the user. E-mails carrying MyDoom-N appear as if they are automated mails. The worm then opens a backdoor in the infected machine, allowing hackers to access it and use it to hack other machines or launch spam attacks.

Govind also explained that variants of the internet worm Bagle, after running through the alphabet from A to Z, have begun appearing in the double alphabets with the latest variant being Bagle.AI. This worm forges sender addresses to confuse the recipient about the worm's origin. With this AI variant, its subject and message bodies give the impression that the enclosed attachment contains pictures, music or information about certain animals, a ploy that seems to be targeted towards younger innocent users who may open the attachment. This Bagle attachment can also arrive inside a password-protected Zip file with the relevant password also enclosed.

Windows Middle East advises you to keep your systems safe by installing and regularly updating anti-virus software, activating Windows’ own advanced security settings and never opening any unexpected e-mail attachments.
