A new worm is making the rounds to machines which haven’t been kept up to date with security updates. The worm works because of an exploit which was patched in October’s Out-of-Band patch MS08-067, which I blogged about.
To ensure you don’t pick this up this new worm, make sure you are up to date on patches and have an updated antivirus on your machines.
