Microsoft’s security update MS10-015, one of thirteen issued this month on Patch Tuesday, was blamed for a number of crashes of XP SP2 and SP3 computers – but as the story unfolds, it appears that the real culprit is a rootkit called Alureon. It was found to be on the XP machines that crashed. Now the authors of the malware have created an update to Alureon. The new version doesn’t cause the crashes when MS10-015 is installed. How weird is that? 64 bit Windows 7 and Vista were not affected, because PatchGuard (kernel patch protection) and Kernel Mode Code Signing thwart the malware.
