Heard of Friday ghosts? The ‘Nyxem-D’ and
‘Nyxem-E’ email worms that come with a timer
to strike every month on a precise day, work the same
way. These worms spread via pornographic messages like
‘Kama Sutra pics’, and they are variants of
the ‘Worm.Win32.VB.bi’, first reported by
MicroWorld. Examining the code, our experts have found
that Nyxem works with a timer and is expected strike
on the 3rd of every month.
On the 3rd of February, Nyxem is programmed to overwrite
all infected files. It shrinks files to 20 bytes and
displays an error message when you try to open them.
Though this worm is not sophisticated in nature, it’s
spreading really fast. On a network, this worm can start
spreading from an unprotected PC and can destroy important
files.
Nyxem proliferates by exploiting the human psychology
to get lured by sexual content. Some of the title lines
of the mails are The Best Video clip Ever, School girl
fantasies gone bad, A Great Video etc, Kama Sutra pics,
Arab sex DSC-00465.jpg and likewise. One of the oldest
forms of virus proliferation, this method is nothing
new. However, it’s still effective as the virus
has already infected more than half a million PCs around
the world till Monday morning.
In nature, Nyxem is a mass mailing worm that disables
security software on the computer and harvests email
addresses from infected PCs. It comes with an emailing
engine and installs itself in the registry.
