The most recent crop of Windows worms continue
to circulate and, what's more, security firm F-Secure said that Zotob,
Bozori and IRCbot are engaged in botwarfare.
“We seem to have a botwar on our hands. There appears to be three
different virus writing gangs turning out new worms at an alarming rate
— as if they would be competing who would build the biggest network of
infected machines,” said Mikko Hypponen, chief research officer at
F-Secure, in a statement. “The latest variants of Bozori even remove
competing viruses like Zotob from the machines.”
F-Secure also said that as of this morning it had found nine malware
instances in addition to the previously reported Zotob and exploit code
from a Russian who operates under the name Houseofdabus.
InfoWorld sister magazine NetworkWorld takes a close look at Microsoft's patching day and finds that it is still a work in progress.
But don't wait for Patch Tuesday to reach perfection. A fix for the Windows hole is available at www.microsoft.com/technet/security/Bulletin/MS05-039.mspx
