GENEVA -- The critical MS08-067 vulnerability used by the Conficker worm to build a powerful botnet continues to be a lucrative security hole for cyber criminals.During a presentation at the Virus Bulletin 2009 conference here, a trio of Microsoft researchers dissected the malware attacks linked to MS08-067 and found that criminal gangs are still exploiting the flaw to plant data-theft Trojans on vulnerable Windows machines.
Microsoft today released a peck of patches to cover at least seven documented worm holes in the Windows operating system. The most serious of the vulnerabilities addresses could lead to remote code execution complete system takeover attacks.
Just one week after Microsoft issued a fix for a worm hole in the Windows Internet Name Service (WINS), malicious hackers have started launching attacks against unpatched systems.The attacks, first spotted by the SANS Internet Storm Center, are hitting Microsoft Windows users who have not yet applied the MS09-039 update.
As expected, the April 1st activation date for the Conficker worm passed without much noise but, as Microsoft and others are explaining, the botnet associated with the worm is very much alive -- and still potentially dangerous."[This threat] should remain a manageable cause for concern and it doesn’t go away after April 1," says Microsoft's Christopher Budd.
Microsoft has announced an alliance of various industry partners whose goal is to fight the Conficker worm. The announcement is short on actionable methods for stopping the worm, but it does include one gem: a $250,000 (US) bounty for information leading to the capture of those responsible for the worm.
