More MyDoom Gloom
fudgefactor7 writes "Hot on the heels of the last virus, Mydoom.b is on the loose. According to Computerworld, this variant has a larger payload and targets Microsoft's Web site for a distributed denial-of-service attack on Feb. 1, instead of The SCO Group Inc. Patch those systems and keep your A-V up to date. Definitions are available currently."
decaying writes "With the amount of virus-laden emails flying about due to the latest virus, Australian ISP Optus have started selectively blocking port 25 outbound. Optus say they are acting in accordance with their "Terms of use", quoting that they reserve the right to restrict access to any TCP/IP port. The only option is to use Optus' SMTP server and nothing else. Community site Whirlpool has an on-going discussion about the issue."
carnun writes "Just another link on MyDoom. Apparently the FBI are also getting in on the act. Interesting to see such a fast response." And to me, the most interesting one: Zeriel writes "After much discussion on a mailing list discussing trojan horses, some people have reached the conclusion that MyDoom doesn't accomplish its stated goal of DDOSing SCO at all! Choice quote from the analysis: "I have the new critter in a test environment where we conducted a preliminary and rudimentary functionality and threat analysis...I have played with the date, etc, but still no activity directed toward www.sco.com." The link also includes disassembly and analysis of the worm code."
It's entirely possible that the authors of this virus targeted SCO, simply to make it appear that Linux zealots were responsible...to throw off the law enforcement officials who might look for the culprit in the Linux community.
While I despise these worms, you've got to admit that some of these more recent ones are pretty ingenious:
Blaster - The only way to fix it is to grab stuff from Microsoft? Have it DDOS Windows Update.
MyDoom - Hate SCO, Love Linux? Target Microsoft systems and leave Linux machines alone. Have it DDOS SCO.
I'm looking for a serious apology (or at least a retraction) for the 'alleged' link between this ugly little nasty and Open Source / Linux users."
Of note: Darl McBride was on local (Utah) television last night with a stinging quote. "What we are seeing here is the dark side of the open source movement" or something very close to that. I thought, no dude, you have it all backwards. SCO is the dark side of the open source movement.

It was covered last week.
Basically, to limit the spread of a worm on a network such as the internet, we can only diversify to make sure not all machines go down.
Here's a presentation (sorry I could only find a PowerPoint version) that was made by Jonathan Wignall at DefCon last year about this topic. Same conclusion, diversifying is the necessary to combat worms.

So basically, SCO being down right now is Yet Another Big Lie from SCO. Nice to see them shown up as spreaders of misinformation yet again. I'm sure the FBI will love to hear their excuses as to why they're pretending to be down, especially if they're attempting to blame the worm. Fascinating
It is likely that this virus has been assembled for the purpose of defaming the Linux developers by spammers, SCO, or others. Your behavior will influence whether or not it succeeds in this mission.
Thus, I urge all persons who have sympathy for Free Software, Open Source, and Linux:
Remember that your actions count. You are ambassadors of our community.

if this is not a more effective form of economic terrorism, I don't know what is. These worms seem to cost US companies millions if not billions of dollars, and they're probably not so difficult to develop either.
With such a hugely damaging effect for such little cost, wouldn't you say that is almost the perfect weapon?
Wouldn't it be ironic if a worm were to DDoS slashdot.
... here at Virginia Tech, the virus has had our pop/smtp servers down since sometime last night. Apparently it infected our financial aid listserv, which caters to 51,000 email addresses, most of them in the vt.edu domain. Not to mention 8000 of the not-so-savvy on-campus undergrads whose systems have been infected. In the 4+ years I've been here, this is the longest downtime for our email system yet, even considering the downtime a couple routine server rebuilds caused. I'm sure other institutions, agencies, and businesses are experiences unheard-of downtimes as well.
May the threads progress competently.
What the hell would it matter anyway? Evil spammers probably also use toothpaste. Does that make everyone who uses toothpaste evil?
The fallacious logic here astounds me. Wait, no it doesn't.
From the post: "Personally, I'm looking for a serious apology (or at least a retraction) for the 'alleged' link between this ugly little nasty and Open Source / Linux users."
I don't know what it is with people trying to represent such large groups. Every group has nasty people in it! Since Linux is generally more efficient once set up (IMHO, anyway), then OF COURSE people will use it to do nasty things like serve spam and make DOS attacks and so on. I don't get why people are so patriotic all the time... "He's American! No AMERICAN could be evil!" Sigh...
A report covering F-Secure's work on the virus reveals this interesting comment imbedded in the virus:
Buried in its programming code -- and only readable after it has been decrypted -- was also the message "Andy; I'm just doing my job, nothing personal, sorry" from the creator
My tinfoil hat says it's some poor guy at SCO!

Also, you forgot to make an RIAA variant, dumbass!
This was some criminal capitalizing on the Hot topic of the Linux vs SCO debate. If this worm has targeted the whiteshouse.gov site you've have the same idiots saying terrorists did it. These criminals just used Linux as a scapegoat. I try to avoid reading articles about this worm because I just can't stomach reading all these posts about how the OSS community should "tread lightly" etc. Get a clue people.

Here's a presentation (sorry I could only find a PowerPoint version) that was made by Jonathan Wignall at DefCon last year about this topic. Same conclusion, diversifying is the necessary to combat worms.
How ironic is that? Someone who allegedly knows something about network security, who insists on providing presentations in a format which:
Fine, use PowerPoint for the presentation. But damn well save the slides as HTML, Acrobat, plain text, etc. for public downloading and consumption.
At my university, the only department which saved all lecture notes, etc in proprietary format (and continues to do so!) was the very one which should know better: Systems and Computer Engineering. It's really pathetic.

Fuck, I'm pissed of more than usualy about Slashdot editors.
If you were to read www.linux.org.ru you would notice that the site follows the suite pretty closely, sometimes more so than Slashdot.

Mr. Burns: Obviously our only course of action is to utilize the dark side of the force. We must make those young linux whippersnappers look bad by making a virus that seems to target our own servers!
McBride: Brilliant! We'll make it look like those linux communists are trying to destroy our legitimate business! Make it so!
Mr. Burns: Eeeexcellent.....
Thus goes the story I heard from a passing lunatic...
Just think, you are one of the first hunter to see the virus. You examine the code, and "Damn, their going after SCO, COOOOOOOOLL, I hate those bastards, I'm not reporting it". Or a sys admin at an email gateway. Most guys are real pros but maybe, just maybe a few took a little extra time...
They say that it's one of the fastest spreading Virus to date, perhaps targeting SCO was the bump it needed.
The grass is only greener, if you don't take care of your own lawn.
Didn't blaster target the wrong address for Windows Update?
DDOS a website that probably gets about 10 interested visitors a day anyway?
Personally I'm surprised at the lack of damage these things do. Our systems and people are apparently wide open to these things. Blaster and MyDoom should be viewed as warning shots. It's only going to be a matter of time before someone writes something that infects, spends 2-8 hours propagating itself and then nukes the system it's living on, causing real widespread damage rather than minor annoyances.

If it turns out that the DDOS payload is inert:
Who was it that FIRST said it WOULD attack SCO, and how did they determine this? And who else quoted them without checking? (Not including normal media outlets, who'll quote anyone that can form a coherent sentence, if it'll fill white space.)
If this thing doesn't perform as advertised, what we are seeing is the first (purposeful or not) FUDworm. It definitely is spreading virus-like and causing traffic problems, but also it's spreading FUD, and using all of us as vectors. We will all have been infected with a socially engineered disease. If this is the case, it's a master stroke of psyops. If not, considering its success so far, its example will be repeated for this purpose.

Email for my domain is wildcarded, so it really doesn't matter that much what's in front of the @ and I'll get it.
The past 2 days I've received a shitload of Mydooms, and there's something funny going on. Mydoom will put common names in front of the @. I've started receiving viruses for brian@ and bill@ and claudia@ and fred@ and jerry@ and george@ and smith@ and and and. I even received one for debby@. What, she's doing my domain now?
I've also noticed that some of the "senders" are constructed the same way.

This is very interesting, because my site has been under a broadly based but inexplicably benign apparent DDoS attack which is bombarding my site with precisely such requests (obviously www.fourmilab.ch, not www.sco.com) at a rate of just one hit from each IP every four minutes. (This rate is not absolutely consistent, and some seem to be running multiple copies of the requester, each hitting every four minutes.)
I've been watching this and running analyses since it became obvious something was up and have posted an incident report page on my site which I'm updating as things develop. Bottom line, the apparent attack appears to have reached equilibrium with a total of 2894 different IP addresses hitting my site since the outbreak, with the hit rate following a diurnal pattern (there's a chart in the incident report) which peaks at around 20,000 hits per hour from on the order of 1000 different hosts at 20:00-21:00 UTC every day.
I'd previously concluded this probably had nothing to do with MyDoom. Although a few of the hosts hitting me are listening on the MyDoom remote control post, most aren't. (Of course, a test version may use a different port or none at all--I discuss in the document.) But the fact that the hits are precisely the same--a simple request to the home page--makes me wonder. All of these sites hitting me request only the "/" page (which at my site is just a <frameset> container, which any browser would follow up with hits on the content frames).
Has anybody else seen this kind of traffic hitting their sites?
In my opinion, I don't think it was a Linux fan that caused it.
Firstly, he attack was not technologically sophisticated, in that it required exploiting a weakness in the operating system. The style of the attack was conceptually sophisticated, it was a worm not a virus. Which means that the attack relied on 'social engineering' or 'human weakness' to succeed.
The exploit however was quite creative. It was multi-faceted, even doing a DDOS on 'www.sco.com'.
Personally, I suspect that the creator and the executor of this worm may be two different persons altogether. Most importantly, the one ultimately responsible for the worm's spread and impact on the internet is not a Linux fan.
Linux users, ones that are capable enough to create such a worm, would more likely be above average intelligence. They would know very well, the consequences of DDOS'sing SCO's web-site, and that these consequences will most definitely be extremely detrimental to Linux. They would also know very well that a DDOS of SCO's web-site is almost a trivial thing to fix, and doesn't help in reducing SCO's position in any way.
Other than making SCO spend some money to rectify the DDOS, and preventing some of SCO's limited customer base from accessing SCO's web-site, it doesn't do relatively much harm to SCO (as compared to finding a back-door or hole into SCO's internal network). There is no real motivation for a Linux fan to carry out a DDOS on SCO's web-site.
I think the REAL reason for this worm, was for a 'frame-up'. It coincides with the conceptually sophisticated thinking as evidenced in its style of attack. I think the real reason was to *help* SCO and Microsoft, because both of these entities have the most to gain from it. Even with the recent 'b' variant of the worm targetting Microsoft. I still think the original motive remains the same.
Either that, or we're dealing with an extremely shallow and stupid 'Linux fan', which I very highly doubt.
People reading this may start having this thought of 'oh, another conspiracy theory...', but I would ask readers to carefully think about the obvious and carefully consider the occurence of this worm. Industrial espionage has been around for a long-time, and we know that it happens. What's to prevent it worms or viruses being used in industrial espoinage? Especially when the internet is a lot more relevant to businesses today.
According to Symantec, this version now modifies your HOSTS file to try and disable the user from being able to reach antivirus websites.
Among other entries in the HOSTS file are Doubleclick, FastClick, and some other advertising-related companies. Should I be concerned or happy that the virus may make surfing the web a little bit better by doing this?
In Win98, I believe the wallpaper filename was stored in win.ini (it doesn't appear to be so in Win2k and this seriously isn't interesting enough for me to look it up at the moment.) We would grab that file and take a peek. If they had an image suitable to be defaced, we would draw mustaches on everyone and draw little cartoon baloons saying stuff like, "UR COMPUTAR HAS EBOLA!!11" and then overwrite their copy of the file. If they had a stupid background, we'd find something funny to give them.
Between the sorely juvenile humor and the liquor, it was completely hilarious to us at the time. I was even called by the school's Computer Support Desk at one time to see if I knew anything about the rare computer virus the student computers had. And before anybody points out how childish and potentially criminal this was, let me say that it was childish and potentially criminal. We just screwed with people's wallpapers but we could have remotely deleted their entire hard drives. Educating the masses about computer security is a difficult task, but goddamn if drawing mustaches on people isn't funny.
The linked mailing-list at,Math.org reports the preliminary disassembly show that the worm only resolves the name SCO.com, and is unhappy if the name doesn't resolve. My guess is that have the name resolve shows the worm that an active internet connection exists, with out tipping it's hand too badly. In test environments the worm didn't attact SCO.com no matter what the computer's date was set to.
Apocalypse Cancelled, Sorry, No Ticket Refunds
I can't believe this worm has been remotely successful. It's hard to believe that so many people are so incredibly stupid.
It's a bloody -attached- zip file, with a file inside it! People have been told for over a decade to NOT OPEN ATTACHMENTS. You'd think they'd catch on sooner than later.
This is all the more reason to strip all binaries from email at the server. Granted, then viruses would be linking to sites - but that'd be relatively easy to shut down, and wouldn't pose any significant threat.

Why is the plural of virus viruses? One octopus and many octopi. One cactus, many cacti. Why not one virus, many virii?
Then why spell it with two 'i's? "Viri" would be correct by your example.
However, in the original latin, "virus" is a collective rather than singular noun (eg "snow" vs "snowflake", although the original meaning is more like "slime".) Perhaps whoever first applied the word to the infectious microscopic critters should have used "virum" as the singular (like "bacterium") in which case the plural would be "vira", but s/he didn't, so we're stuck with "virus" as the singular and an argument over "viri[i]"/"viruses" as the plural.
Personally I think it should be "viruses". You wouldn't say "many doofii", would you? It's "one doofus, many doofuses".

How many e-mail server admins here are running up to date anti-virus software so that they aren't contributing exponentially to this problem by allowing their clients to get these infected e-mails in the first place?
*raises hand*
Oh yes, and Hotmail over there.
These viruses can't infect Linux (yet) but that's no excuse not to run anti-virus software that kills off virus infected e-mails on your Linux servers so that they're not getting to "clueless Windows users" in the first place.

;-)
That's not even worth mentioning. There is no good reason for the average user to need access to SMTP servers besides the one at their ISP.
Years back, when I did technical support, the ISP I worked for had just implemented such a filter. The number of spammers who used our services immediately found new ISPs. The only fallout were a few customers who needed email clients reconfigured for non-local mailboxes, as they were using the other ISPs smtp server.
I do recall a few knuckle-heads (NT4/Linux wannabe super geeks) whine excessively over the issue, as they felt some right of theirs had been infringed. Ignorance is bliss, I suppose.
For anyone who is considering Technical Support for a living, just hang up the phone as soon as you find out someone is from Boca Raton, Florida. I swear, everybody I've talked to from that place thought thought they were some guru, but usually had no clue. My point, if you are such a damn brilliant administrator, then you shouldn't be calling technical support whining about your messe d up copy of enduroo.
Back to the topic at hand, there is no excuse for any ISP who houses an smtp server to allow it's customers access to just anywhere on port 25. I know it's a subject that will cause some flames, but someone has to compensate for the insecure, broken nature of SMTP.
I welcome anything AOL or Microsoft can bring to the table concerning this matter. I definitely don't see the community doing anything about it except for yelling at people to add more filters. This does little in regards to the bandwidth costs and server time (not to mention my client's cpu time wasted filtering) associated with massive amounts of spam.
I immediately clicked on the feedback link on the BBC website and let the editors know how lopsided and unreasonable their reporting actually was, pointing them to the groklaw.net website as well.
I have considerable experience in attempting to correct misrepresented facts in the media and know that it is often quite hopeless, but if enough people do it and give some proper backing to their arguments perhaps some of the damage can still be repaired.
