RPC DCOM Cleanup Worm Appears

Posted by simoniker on from the someone-with-twisted-sense-of-humor dept.

UnderAttack writes "This morning, the SANS Internet Storm Center posted a note about an increase in ICMP traffic, including a quick initial analysis. As it turns out, yet another worm, this time the W32/Nachi.worm, is going around taking advantage of the RPC DCOM vulnerability. The twist this time: the worm will actually clean up machines. It tries to download the correct patches from Windows Update and remove the Blaster worm."

    Basically, No. Nothing happened.

    If I would make a guess, it's most likely this. Pretty slick; it allows you to scan IP subnets.

    For those Windows sysadmins that don't know, you can use SUS (free from Microsoft) on a local server to distribute updates via Automatic Updates. The clients need to be configured, through Group Policy (or manually, if you wish), to use your server instead of Micosoft's, but it can scale quite easily to enterprise level.

    It needs IIS to run, but it runs the IIS Lockdown Tool at the same time.
