A new version of the Neeris worm is exploiting the same Microsoft flaw as Conficker. The Neeris worm dates back to 2005, according to Microsoft. “It is interesting to note that this new variant of Neeris spiked on late March 31st and during April 1st,” stated Microsoft Malware Protection Center. “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.” The new Neeris variant is detected by Microsoft as Win32/Neeris.gen!C. Earlier versions of the worm exploited MS06-040, which addressed a vulnerability in the same Server service as MS08-067.
