| The Nyxem-D worm can pose as pictures of the Kama
Sutra. |
Experts at SophosLabs™, Sophos's global
network of virus, spyware and spam analysis centers, have warned
users to be wary of unsolicited emails claiming to contain obscene
pictures and sex movies.
The W32/Nyxem-D
worm (also known as Email-Worm.Win32.VB.bi, Blackworm, or
W32.Blackmal.E@mm) can spread via email using a variety of
pornographic disguises, in an attempt to disable security software.
If launched it tries to disable a number of anti-virus and firewall
products, and attempts to harvest other email addresses from the
infected computer, in an effort to spread itself further.
Subject lines used in the malicious emails include the
following:
*Hot Movie*

Fuckin Kama Sutra pics
Fw: SeX.mpg
Fwd: Crazy illegal Sex!

"Companies should educate their users to practise safe computing - that includes never
opening unsolicited email attachments and discouraging the sending
and receiving of joke files, pornography and funny photographs and
screensavers," said Graham Cluley, senior
technology consultant for Sophos. "This worm feeds on people's
willingness to receive salacious content on their desktop computer,
but they could be putting their entire company's data at risk."
The W32/Nyxem-D worm has a destructive payload, which triggers
on the third day of any month, destroying DOC, XLS, MDB, MDE, PPT,
PPS, ZIP, RAR, PDF, PSD and DMP files by replacing their contents
with the string:
DATA Error [47 0F 94 93 F4 K5]
