Kama Sutra In Your Email

by CXOtoday Staff    Feb 02, 2006

A new worm W32.Blackmal.E@mm has started infecting systems and threatens to launch attack on third of every month, with the next attack expected on 3rd February. The mass-mailing worm is also referred to as Kama Sutra worm due to the content of the email it sends.

Blackmal.E attempts to disable and remove Internet security software. When executed the worm attempts to overwrite user files such as Microsoft Office documents and PDF documents. It has infected more than thousands of machines over the past week; most from unsuspecting users who do not yet know they are infected.

Like most worms, Blackmal.E propagates via email attachments and network shares, including popular P2P file sharing services. It also gets transmitted via email through social engineering techniques, including the promise of pictures, pornographic content, or a joke to entice users to open the corresponding attachment.

Blackmal.E is also known as Email-worm, Win32.Nyxem.e, Email- Worm.Win32.Nyxem.e, W32/MyWife.d@MM, Win32/Mywife.E@mm, W32/Small.KI@mm, Tearec.A, W32/Nyxem-D, WORM_GREW. {A, B} Nyxem, Mywife, and CME-24.

The systems that are likely to be affected by this worm are Windows 2000, Windows 95, Windows 98, Windows Me, Windows NT, Windows Server 2003 and Windows XP.

Security precautions for users include not opening unknown or unexpected e-mail attachments, keeping Internet security software up-to-date, using strong passwords and backing up crucial data.
