Code Red Back For More

timothy posted about 13 years ago | from the more-bells-more-whistles dept.

Bug 866

Brian Stretch writes: "The Code Red II worm was unleashed early this morning and appears to be very different than the original and far more dangerous. CR2 infected servers only attack servers within their Class A address block and their Class B address block in particular: since 9:11am EST I've logged 148 CR2 attack attempts, 89 of which are from within my Class B subnet, suggesting that only servers within Class A networks that were deliberately seeded are being attacked. The 24.x.x.x range is one of the hardest hit, and as before, it's folks with cable modems and DSL connections that are providing the most victims." Several @home customers have written about slowed service today, but they're definitely not alone.

My IP is 24.17
The modem light is just constantly on. I've even unplugged the modem from my router to confirm it is an external access, and sure enough the modem light is just chattering on constant with incomming traffic. Amazingly, I am still able to get out and the throughput is still very good in SE Michigan.

Does it spread differently / attack more often?
Or is the random number generator better than in the original?

Looking at my logs, the first time I got an "/default.ida?XXX" was at about 9:45am PST. About an hour later I stopped getting Code Red I's NNN's in my logs.

This seems to show that the new Code Red worm kills the old version. I don't have any attempted connections from Code Red I in my logs anymore (since about 11am PST).

Re:A few more details (5, Insightful)

nebby (11637) | about 13 years ago | (#2127731)

I haven't done any analysis of the worm myself, but has anyone questioned the possibility that this new version is phase two of the original worm? Not the same code per say, but perhaps the old code red does something to tell the new code red to "come here" or something?

The fact the old code red is turned off tells me that they might be linked to the same person/organization or something.. if I were some independant cracker I wouldn't bother getting rid of the old one since that's another thing which might break when I launch the new worm.

However, the article mentioned that the worm stuck either within its own class A or its own class B, and I was merely commenting on the sitution in my own slice of class B heaven.

Anonymous Coward | about 13 years ago | (#2113453)

If these viruses/worms/trojans/what have you are designed to make the general public aware of the design faults of the Windows operating system then why don't they write them to do something even more drastic like install Linux or one of the BSDs* over top of the existing OS?

The ideal code red worm in my opinion would take the contents of a website, send it off to another infected host, go about it's business installing an alternative OS and then bring back the data and have the system up and running again with the alternative OS. This would bring up all the uproar about the problems which is what the writer wants, while seemingly solving a problem at the same time. Plus it gives all those administrators that are stuck working with Windows but want to switch to something else thier chance!

* yes I know that Linux and *BSD have thier fare share of security problems too, I am mearly using them as an example.

Re:Why? (0)

BassGuy23 (308297) | about 13 years ago | (#2114057)

Anyone who could write an install program for Linux that worked correctly, worked quickly, was small enough to propogate itself in a reasonable amount of time, and was able to translate the host software config to the new Linux config would be sitting on a fat stack of cash. That would truly be Linux for the masses. Hell, if it could recognize my network card without a major effort on my part, it would be Linux for the masses. Unfortunaetly such a thing will probably never happen. But if it did, it would be even better if it spread itself. Imagine the embaressment at Microsoft when all of a sudden all their servers are running Linux and, due to a "security flaw" in the distro, Windows has become "open source". Just my 2 cents. I should probably be sleeping right now.....

when will you people realize that code red is not just another worm that will fade away soon.. code red makes not only IIS webservers vulnerable.. but any service with an available exploit. i'm talking about the "code red algorithm" that it uses to scan the ip's and spread so fast. this is what makes code red so special.. and this is why we'll be having more of this soooner than you guys think.. its DDOS days all over again..

MavEtJu (241979) | about 13 years ago | (#2119350)

- reverse DNS is not done everywhere. It would be so easy to track things down if forward and reverse DNS were in sync
- email aliases like abuse, webmaster and hostmaster are not common on windows-machines.
- email aliases like abuse, webmaster and hostmaster are not common under domains.
- whois-servers of ccTLD are often hard to find or inoperative (hint to ICANN: we *NEED* whois!)

I really hate these webservers which give me an unreadable (prolly some asian font) page, without any clue on who to inform.

Of the more than 100 unique messages I send out this weekend, more than 80% completly bounced because there was no abuse/webmaster/hostmaster alias.

Anyway, I don't foresee any job-problems for people who try to educate internet-newbies with common rules like reverse dns and aliases for common mail-names...

This Limited Warranty is void if failure of the Product has resulted from accident, abuse, misapplication, abnormal use or a virus.


Some states/jurisdictions do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you.

Admittedly, it being in the same /16 I'd expect to see more attacks from it, but unless it scans the entire /16 every 5 seconds I think it is a sign of a broken random number generator.

Can you either post the source, or a link to the source? I'd like to do the same (I have over 350)

its not the greatest script but its what i used

# Opens logfile and picks the ip's that attempt to pass the code red virus
# Location of Log File
$LOG = "/var/log/apache/access_log";
#begin code
open LOG or die "Cannot open $LOG for read:$!";
$count = 0; # ip count
@ip; # array of ip's
while (){
if(m@GET /default.ida?@){
#sort ip's (this is a slow sort.. beware)
print join "\n", sort {
pack('C4' => $a =~
pack('C4' => $b =~
} @ip;
print "\n\nThis Box Has Had $count Attempts On It By The Code Red Virus.\n";
#end code

For those who are interested in the source:

On another note, a server whose identity I will not name(solaris w/ apache) was hit with 17000 attacks as of yesterday(the server handles a lot of ips).

a quick fix (2, Informative)

Swordfish (86310) | about 13 years ago | (#2128360)

Here's a perverse idea for a quick fix for CR2.

First, see here [] for how to telnet into the back door left by all CR2 infections. Second, write a script to telnet to all infected hosts which probe you on port 80 and shut down the offending machine. Third, run this script on your web server so that all hosts probing your site get shut down.

If everyone did this, then CR2 would disappear off the net within 24 hours, and we could all rest easy!

Re:a quick fix (2, Funny)

dozing (111230) | about 13 years ago | (#2136777)

Wouldn't the best and quickest fix be to telnet into the machines and give 'em the old:
c:\deltree windows

maybe we could even install scripts on our own servers to automatically do this each time we recieve a new attack. Automated windows repair solutions.

New Code Red Variant (1)

cfreeze (146454) | about 13 years ago | (#2134662)

I sent this in as an anonymous story, but it looks like this one got posted instead. According to [] there is a new variant of Code Red (of which this would be the third version). This one installs a backdoor. As someone else posted here, the tell tell sign is that the buffer overwrite payload is now a string of 'X's and not 'N's as in the previous two versions of Code Red. The stakes have been raised folks.

@home problems... (2)

garett_spencley (193892) | about 13 years ago | (#2136085)

Slow service? I don't know about other @home customers (I'd like to hear) but my net connection was completely _down_ for about 8 hours this afternoon. As a matter of fact I just got back on.

The interesting thing was that the "cable" light on my cable modem was still on when usually when I can't get on the net it is off.

So I wonder what the problem really was. If maybe the routers were all up but the dhcp servers were down or something....

Anyone else have similar problems?


Re:@home problems... (1)

jmitchel! (254506) | about 13 years ago | (#2133155)

I noticed this afternoon that my recieve light was always on on my cablemodem too. It is continual arps, which I just realized were the product of infected computers trying to scan non-existent addresses, which the routers have to try to resolve.

The benifits of friendly neighbors (1)

dozing (111230) | about 13 years ago | (#2136089)

I see a couple people saying they are getting a lot more of these hits than the original code red. Considering that someone earlier posted that it attacks the largest percentage of the time in its own netblock I'm happy to have my server living in an exclusivly linux netblock. I've only seen one of this new variant so far (from if anyone's interested.) According to my snort logs its come accross my /24 network only 18 times. It pays to have nice neighbors.

Why don't they... (4, Insightful)

Greyfox (87712) | about 13 years ago | (#2138054)

Modify the code red code to apply the security patch to the vulnerable IIS servers and reboot the system? While this is potentially destructive to your system (I'm told -- MS security patches and all that) it would pretty well take care of this problem...

Re:Why don't they... (1)

jgaynor (205453) | about 13 years ago | (#2118513)

That is probably the smartest thing I've ever heard anyone say on slashdot. Ever. Someone Show their skills and write a variant that will run the patch (obviously not locally if they dont have it) from a remote server. Yeah you can hate MS all you want but until someone does something about it we're all going to be sucking bad HTTP requests.

cisco 675 hanging. (1)

Teratogen (86708) | about 13 years ago | (#2146669)

I have port 80 on my Cisco 675 router turned off.
In fact, it was the first thing I did when I configured the router. But somehow this Code Red worm is still hanging the router occasionally, so that I have to power cycle it. Anyone know why this is happening?

Hypothesis (2)

nebby (11637) | about 13 years ago | (#2146670)

I bet they launched it on Saturday morning on purpose (or Friday night even.) By the time Sunday is over, the hacker(s) will have root access to a shitload of computers, and the sysadmins who hesitated patching showing up Monday morning will have long been 0wned.

Like someone said elsewhere, the best (and only I think) way to partially fix this problem is to write a variant of the worm (Code Green? :)) that fixes all the servers before it gets out of hand. Apache server or not, if 100,000 computers are infected, the traffic costs of Code Red 1, 2, etc. hits alone will be enough of a incentive to fix the IIS servers. (Though it is kind of exciting to think of Microsoft having egg on their faces Monday morning when they get DoSed by 100,000 cable modems in one deafening yell.. but I digress)

Do you think the RIAA cares what happens to their web server? They'd love it if the entire Internet went down in flames, which we're told is what will happen if code red or some variant that actually worked would clog every pipe entirely. Their puny web server would be a small price to squeeze out all the bandwidth being used by mp3s.

Free r00t for all! (1, Insightful)

whatnotever (116284) | about 13 years ago | (#2150030)

So here we basically have thousands of boxes with open backdoors, _broadcasting_ their presence to the world.

And with people so nicely distributing their logs here in this forum, the collection of ips is easier than ever!

Now that they have the backdoors, though, how hard would it be to patch them remotely? I'm thinking that if you put up a single exe on any old webserver, you could tell each infected host to just download and execute it. The only problems are writing the exe (not too hard), and figuring out how to get the host to download it, using the backdoor (probably trivial).

Re:Free r00t for all! (1)

testify (174404) | about 13 years ago | (#2120744)

Yes, and where you have an unpatched IIS install, you often get a wide-open FTP server running as well. It's been making for some interesting browsing.

Re:Free r00t for all! (1)

krogoth (134320) | about 13 years ago | (#2127570)

just write a win2k .bat to install the patch, and write a perl script to telnet in to any IP and use it if possible. It might cause data loss, but if there is no other way to fix sysadmins, it should be done.
