Get that firewall up!
New worm on the loose
(old news - 07:30PM Monday Aug 11 2003)
tags: security
It appears that a new worm (for now we're calling it msblast after its executable, msblast.exe) has surfaced today. It attacks port 135/tcp (that's Netbios), creates lots of RPC noise - some users report random machine shutdowns and reboots - and once it takes up residence in your computer, it proceeds to scan a random IP range and propagate itself to unprotected machines. Since this worm is brand, spanking new it may not be detected by (even recently updated) anti-virus software.. so get that firewall up and secured!

Based on analysis posted by users psloss and Steve in our security forum, this worm will start a DDOS attack against port 80/tcp (which is basically web) of windowsupdate.com on August 16th. In other words, if you wanted to update your windows this weekend - today may be a good day to do it after all.

Check out the ongoing thread in our Security Forum for newest analysis and information.

Port 135?!

Whoever has any numbers below 1024 open is really asking for it!

Matter of fact whoever has any ports open is asking for it!

Re: Port 135?!

Let me ask you this,

I run my Norton Anti Virus and keep it updated (Even though this is new, so I doubt Norton has updated itself for this as of yet) and also run my network at home behind NAT. What else can I do to take even more precautions in regards to this?

TIA,
Whiteice

If you are behind NAT that you are pretty much okay. If you dont have port 135 forwarded to any computers for a VPN or something (not required anyways because of the tunnelling blah blah blah).

So you should be fine. Only people running their machines with ports open like others here, or no NAT firewalls at all, would have something to worry about.

You really dont even need a software firewall with NAT but it depends on your browsing habits. OI only get email from 10 people tops, no attachments (mostly) and never any .vbs, exe. pl or whatever that can execute.

Re: Port 135?!

Sounds like the football calls. Blue 80, Blue 22 Hike. I got my Linky up and running, My Norton AV fully updated, Zone Alarm going, and for safe measure, why not try a fresh & friendly DSLR port scan. Have the techies run free if I don't secure it. GOD I hope I don't have to reformat again its been my 3rd time this month, since I installed Satan's Pack I from Windows Update.

Zone Alarm has been blocking 73.165.128.151 to port 2268 TCP Flags SYN all of two weeks now. I haven't looked it up yet, I was about to and saw this thread.

I had Linksys hooked up but due to some computer diagnostic's it isn't right now. I ended up having to re-format the hard drive.

Guess I should hook it back up post haste?

Yeah keep the linksys on at all times. I had only 1 computer and I had a NAT box. I dont ever update my machine unless I need to. I havent updated ANY of my computers to patch the worm because I am behind NAT. The firewall is good encase it somehow makes it onto your network, you will see it trying to download the meat and potatoes to your computer. The msblast.exe alone doesnt harm your machine (or so others say), only when it can get out onto the web and start reaking havok on your connection. NATs really cant protect against outgoing connections (although you can block incoming and outgoing ports).

So I'm going to hook it up. What ports if any should I block (and how) on the Linksys?

When you say keep the Linksy's on at all times, do you mean as well as the modem? Someone told me to keep them both on all the time and I thought they were in idiot.

I used to always keep the Linksy's on but turn the modem off, sometimes un-plug it.

Hee hee! Why would anyone even own a pc for that matter? 95% of worms, virii, and nasty scripts are written for the M$ platform. The other 5% are diviied up between Mac and Linux. I haven't run a virus scanner on my Mac in years. My pc I find I'm constantly checking for all kinds of crap. I spend more time doing maintenance on it than anything else. What fun is there in that? I'm way more productive on my Mac.

Alky-

You are preaching to the choir here. My desk is surrounded with 2 Mac's (G3/G4 OSX) and 1 Intel Linux (RedHat 9) Desktop, 1 Linux RedHat Notebook.

(almost) Everyone in my office building is running around like heads with their chickens cut off. Some offices have high-end firewalling using outboard NetScreen & IPIX iron, but the worm still got through.

Here is the funny part; I had a scheduled sales presentation (remote data disaster recovery services) today and one of the "competitors" whose pitch was 2 hours before mine ran my meeting late...his laptop PP presentation wouldn't fly...his PC laptop kept going into a forced shutdown. My StarOffice demo ran like clockwork.

Why people continue to put up with this "platform" escapes me.

Hey Alky,

Thats the same argument most people have used just before they got AIDS.

"Hey, I only get involved with 5% of the people I date, I am OK" "What fun is there in protection" "I am way more active doing it my way"

Oops, sorry we are talking about computers, not people here.

All of my ports are blocked using Norton Internet Security. Have been using this firewall for over two years now. A port check via the Symantec website lists all of my ports as "stealth." Anyone who uses the Internet, especially via a broadband connection is foolish to not be using a firewall.

Disable system resore if using XP or Windows ME.

Open registry editor, go to:

Software
Microsoft
Windows
Current Version
RUN

delete the entry for Windows Update which has a value that executes MSBLAST.EXE

Restart in safe mode, delete the file MSBLAST.exe from C:\Windows\System32
or
C:\Winnt\system32

Reboot and then apply the patch from Windows Update and update antivirus software.

you need to lock the door

goto start button then control panel then to preformance and maintance then to Administrative Tools then Computer management then sub under adminstrative tools click local users and groups in the left hand side on the right hand side it will show a list of diffrent logins to your computer any you did not make delete the 2 that it will not allow deletion ones Administrator the other a guest account password protect them then goto c:\winnt\system32 look for msblast.exe delete it then goto registry delete the reg key for it there then go back to the system32 directorie and look for any folders with out of place nameslike (inetserv comserv saved uploads dloads) you should also check for files and folders in the c:\winnt\system32\drivers\etc folder
you could do a search for files ending in .sah .bak .pid .bat these files are common to sdbots and to msblast.exe as there seems to be 3 parts to this bot 1st a ftp 2nd a irc xdccbot 3rd a self contained scanner and auto rooter very fancy piece of programming to bad i found all three peices man people will be mad at me lol

people just goto the computer management and then to the sub dir user and group accounts close and password all you accounts and delete the ones the windows makes at instal.
then go find the msblast as you call it its actually a sdbot you can remove it by finding the host folder it usually is c:winnt/system32/drivers/etc or c:/winnt/system32/config
best idea is look for folders that just do not belong eg Certserv or Jobs Cpuidle these folder will be in system32 folder so look there they will be hidden folders and files look in the reg and edit the HKEY which controls rundll32.exe Microsoft does know about this pronlem but chooses not to fix it

The article is wrong, port 135 is not NetBIOS, those are reserved for 137-139.

Port 135: Microsoft's DCOM (Distributed, i.e. networked, COM) Service Control Manager (also known as the RPC Endpoint Mapper) uses this port in a manner similar to SUN's UNIX use of port 111. The SCM server running on the user's computer opens port 135 and listens for incoming requests from clients wishing to locate the ports where DCOM services can be found on that machine.

It's "close enough" - though it's not strictly part of NETBIOS in the sense of file mapping and the like, it's so intricately related to "windows networking" that most of us have long considered RPC portmapper to be part of NETBIOS. Perhaps this is sloppy, but not much.

I got hit by this worm this morning. My roomate was playing project IGI 2 when I saw for a brief second the message informing you that the system will shut down in 60 seconds. I told him to save the game and quit. Sure enough as soon as he exited out of the game it rebooted.

When my computer came back up (XP PRO SP1) I noticed that the activity lights on my router were going nuts. I enabled the firewall packaged with XP and checked the log. Sure enough my computer was scanning class A networks in the 19.xx.xx.xx range on port 135. I checked my task manager and started killing things until the network traffic died. As soon as I killed MSBLAST.EXE my network traffic stopped. I did a search on my C drive and found 2 files - MSBLAST.EXE and MSBLAST.EXE-09FF84F2.pf a prefetch file.

I moved msblast.exe to my desktop and changed the extension from .exe to .txt

subsequent running of the program prompted more network traffic which was confirmed by my firewall logs.

so YES GET YOUR FIREWALLS UP!!

and do a search on your hard drive for 'msblast' to see if you have been infected. and delete it quickly.

I did a search on msblast.exe in all search engines and came up with nothing. I must have been one of the first hit by this worm. It is very small only 8K and the prefetch file is only 16K so it is easily propagated even on dialup.

Changing the administrator password won't help in this case. This worm works by hijacking a process (DCOM server) that's already running as administrator. Once it's running in place of the DCOM code, can do whatever it wants, no password required.

it is not a worm it is a trojan designed to serve MIRC it is designed to root new hosts etc but it also serves movies games and what ever else its master wants it to serve. if you remove the reg key and you delete the files close the admin account it will stop the bot... i have post other responces with very percise insturctions as to how to stop these intrutions...

Today 2 of my friends told me of this problem, sounded weird their computer would shut down after a time-limit thing expired.

I thought it was a coincidence, than later THREE more of my friends told me they had the same thing going on. I KNEW this was something new, and it looks like I was right.

I have this problem too, but after installing a firewall it was fixed. Later, I installed this: »www.microsoft.com/technet/treevi···-026.asp patch, turned off my firewall, and it was fixed aswell.

Hello scsiguru, yes actually I go to school there .

I've already installed the Sygate Firewall and it is up and running, I posted the other message on my old computer while I was researching the best way to rid myself of the worm, thanks for all the help guys.

I know it a pain in the butt.. but lesson learned... install OS/Drivers/firewall while unplugged from the net.. plug in and then update everything - an unpatched OS or firewall might be vulnerable but it will stop the the old stuff that is still out there probing away until you get everything up to date.

If its one of the new ones that can exploit your firewall/OS before (but not after) you patch, you probably would've gotten hit even if you didn't rebuild unless you save your patches to backup so you can apply them in the event of a reinstall prior to reconnecting to the inet.

Yea unfortunately I have this POS virus and my norton system works isnt picking it up even thought I've ran live update 20 times...I managed to contain it somewhat...I deleted the two msblast files and deleted the registry string...How can I block port 135??? It may already be blocked, but how would I go about doing it on my router?? I have a D-Link DI-804...Man this sucks...I also read that embeded in the virus was a sentence that read, "I Love SANS!!! billy gates why do you let us do this. Stop making money and fix windows!!". "SANS" refering to its alias Lovesans i'm assuming.

Turns your workstation into a DDoS client against predominantly IRC servers -- port 80 has little to do with it. There was a major network-wide (all servers) attack on all EFnet IRC servers with over 50,000 compromised Windows machines.

Who did it? One person. *One*.

Recommendation: do not try to get rid of this thing, just format and re-install. *shrug* It's just not worth the risk.

EDIT: Here's an applicable URL over at CNet that contains information about what it actually does. Yes, it installs a service, registry keys, and all sort-of other fun stuff.

MAKE SURE YOU CLOSE THE DOOR

my freind this will definetly get it out but if you do not fix the cause it not gonna help ya at all....
you must close the DOOR people to do this you must add a password to the Administrator account that windows makes at install.... you find that in the control panel, preformance and maintenance, Administrative Tools, Computer Management then sub dir system tools you see local users and groups go through there and any account you didn't make delete the 2 it will not allow you to delete you need to password protect... this will stop it from happening it will also allow you to see if the rest of it is still working... there are 3 parts the ftp the sdbot and the ddos bot part of it... to see this activety open up windows task manager by pressing alt ctrl delete one time all at same time... do not do repeatedly or computer will reboot...

About closing the door. Isn't there a program that allows you to close certain ports?

I got it first a few days ago, and then today it was a constant flood of them causing my computer to shut itself down constantely. Here's the thread I started early today:

»[2K3] Windows Keeps shutting itself Down!!!

I installed the patch supplied by microsoft, and that seems to have worked just fine. I just can't imagine what kind of impact this has on 2k3 servers on some buisness machines...the kind that never shut down, will now be constantely shutting themselves down unless patched. I did log some activity once I started up Zone Alarm, all the connect attempts on port 135 were from my local ISP, so I'm guessing the code in the worm is set to start a port scan orginating from it's public ip, and scan from there. This is a widespread worm as I logged 20 different connect attempts from 20 different clients on my ISP's network (as well as 2 from another SBC network) We'll see the real effects in a few days.

They, and their connected clients, should be inside of a good hardware firewall perimiter - if not, they shortsightedly set themselves up for just this sort of problem. Servers that for some reason have to have a network connection direct to the outside or have ports like that forwarded through the firewall, need to have arrangements in place for constant monitoring and maintenance. Any business that has to run servers has to set up and maintain them properly and safely, just like any other piece of equipment. You can make an argument about whether home users should have a hardware firewall with a broadband connection, but not a business running servers.

Re: Port 135

If DMZ is not setup, generally yes, but you should block the port 135 and 4444 in your Router just in case.
4444 block is in case you have the worm, so you dont spread it.

Re: no wonder....

not sure what firewall you are using but in ZA Pro/ZA Free there is a log link, and it shows the log, under Destination IP and after the IP address is the port number.
