One of our servers got hit. Still trying to figure out what to do about that.

My servers are getting blasted already. Good thing they're OpenBSD.

This could be very serious. At least one web security firm is issuing strong warnings that this new worm (dubbed 'Nimda') is spreading far more rapidly than Code Red, and that at least a million IIS servers are at risk.

A /. thread here has more info:

You just reposted the original link twice.

Love, a safe little Mac User. (Oh, yeah.)

But I sympathize, really. ;-)

I know. My bad.

Even safe little Mac users aren't safe -- even though you won't get infected, you will still get hit with the traffic to all your favorite websites, no matter what server you are running them on. My safe little Apache sites got hammered this morning and the traffic keeps on coming. Worms don't discriminate. We all get screwed because of Microsoft's security holes.

It's called W32.Nimda.A@mm

I'm getting hit too. Thank God for FreeBSD...

The entire internet is getting slammed by this worm: http://www.internettrafficreport.com/

One security email I received noted that it started just about to the minute of exactly one week since the first plane hit the WTC.

damn... just looked at my logs and... damn.

In support of the theory (re: LeiaS's email):

We cannot discount the coincidence of the date and time of release, exactly one week to (probably to the minute) as the World Trade Center attack.

Of course, I also heard this was a hoax to cover up the slowdowns caused by Carnivore ;)

Honestly, I have a hard time feeling sorry for all the people out there who are hit with this, seeing as they are still vulnerable to a bug found on October 17, 2000. Maybe this is the Darwinian equivalent in the computer world -- you don't patch your servers, and they don't survive.

I know that our server that was affected was up to date at least as of Code Red (it is not my duty to keep up with the patches). We ran the Microsoft tool for checking that all patches were up to date then (and probably since, I just am not aware of exact times). Is Nimda finding an unknown exploit?
posted by LeiaS at 2:41 PM on September 18, 2001


This is a very aggressive attacker. Reports are that the Nimda worm tries to exploit 16 different known vulnerabilities in IIS, contains an FTP component (that is used to install a DLL) and an SMTP server to send emails with attachments, and maybe worst of all, exploits an IE bug that allows a multipart MIME file to execute and infect a machine, simply by viewing a web page.

Here's the Microsoft Security Bulletin about it.

The clones of this worm are gonna be *really* interesting to see...

cfj:

this patch seems to be the most recently recommended for the problem at hand.

Why doesn't somebody cook up a worm that causes physical damage somehow to unpatched IIS servers? That would seem to get admins off thier asses.

Yes, but unlike Darwinian natrual selection, when one species kicks the bucket, it usually doesn't turn around and beat the hell out of all of the stronger species around it...

Trend Micro posted a free cleaner for "Nimda". This cleans the infected *.exe(s), and deletes the many *.eml, for starters. It did not seem to remove the added javascript from *.htm(l) and *.asp though. It got us back up.

The other major virus companies I have tried simply delete all infected files - some fix! I personally tried Norton, InoculateIT, and McAfee to no avail. What do they want the big money for?
