An updated version of an old worm is targeting the same Microsoft
vulnerability exploited by variants of Conficker.
This time around, MS08-067—a
patched flaw in the Windows Server service—is being targeted by a new variant
of the Neeris worm. Neeris first appeared in 2005, but is now back on the scene
with new
functionality similar to the Conficker worm.
“It is interesting to note that this new variant of Neeris spiked on late
March 31st and during April 1st,” officials at the Microsoft
Malware Protection Center stated in a blog post. “However it was not
downloaded by any Conficker variant and there’s no evidence that it’s related
to Conficker.D’s April 1 domain algorithm activation.”
Conficker.D is also referred to by other vendors as Conficker.C, Downadup.C
and other names. The worm is estimated by many security researchers to
have infected millions of PCs.
