Another Nasty Outlook Virus Strikes
Goldberg's Pants writes: "ZDNet and Wired are both reporting on a new virus that spreads via Outlook. Nothing particularly original there, except this virus is pretty unique both in how it operates, and what it does, such as emailing random documents from your harddrive to people in your address book, and hiding itself in the recycle bin which is rarely checked by virus scanners." I talked by phone with a user whose machine seemed determined to send me many megabytes of this virus 206k at a time; he was surprised to find that his machine was infected, as most people probably would be. The anti-virus makers have patches, if you are running an operating system which needs them.
I have received the first email sent by that thing three days ago and reported some brief analysis to bugtraq, got a "rejected, send to incidents" response, sent to incidents, and apparently there is still nothing in the archives -- I have no idea why, incidents list posts all kinds of "I have seen a big spider hanging over my keyboard, I think he tried to hack me" stuff.
.For everyone interested, messages with virus and extracted infected documents are here.
Contrary to the popular belief, there indeed is no God.
> Why can't these virus writers do something cool?
You don't want virus writers with imagination. You *really* don't. A truly imaginative virus writer would likely devote all sorts of creative energy toward thinking up nasty things to do to your computer.
I'm still waiting for the trojan that silently installs itself, then once every day looks for spreadsheets on your system and randomly changes three numbers in every fifth file. Or perhaps it finds your Word documents and randomly removes the words "do not" from a few places. Or maybe it flips a few bits in your swap file, or munges your C++ compiler so that your programs randomly destroy the user's partition table one time out of a thousand. Maybe it sends death threats in your name to president@whitehouse.gov, or anonymously tells Microsoft that your company is pirating Windows.
No, I'm quite happy with the current crop of dull, stolid, entirely *un*imaginative virus writers, thank you very much!
I'm on MacOS using _eudora_ and all these sorts of files are dead inanimate matter to me.
Almost a megabyte of dead inanimate matter over a 56K modem just since this afternoon alone...
I am _so_ _pissed_ _off_ at this crap. I've taken to spamcopping the victims, using this note to their postmasters (where applicible):
"Please suspend this user's account. They are propagating the SirCam worm, and that must stop directly.
-postmaster@airwindows.com"
I have it as a clipping ready to be dragged into the spamcop personalize box, which is what I do when I am so overloaded with spam that I can't get time to type, but not so overloaded that I just give up- which has been the case until recently and this is what brought me back into the fray. _I_ _hate_ _this_... can't we declare Outlook illegal or something? Classify it as a weapon for denial of service attacks.
So why doesn't Outlook do this automatically? Seriously - Outlook could set up a dummy user account at installation time and whenever an attachment is to be executed it could use the previously created dummy user to execute it. To all the posters who wrote that setting up a dummy user to execute attachments is too hard for most users, too cumbersome, or too inconvenient, what's the problem if this is built into Outlook and transparent to the user?

absolutely not. One of the things I learned practicing law is that the reason we're not in serious danger from the criminal element is because *criminals are stupid*. They don't draw the connection between crime and punishment. THeir planning is lousy. I actually had one where five of them stole 70,000 (using my client's mother'ss car as a getaway vehicle), and each took their $5,000 share. It took the police ten minutes to get it through to them that the ringleader ripped them off.
Or the one that had to be rescued by the police after getting toasted, robbing a bar with a toy uzi, and then *going back in*, whereupon it was recognized and he was stabbed nearly to death . . .
If they had what we generally think of as "Average intelligence," we'd be in serious trouble (of course, this would in many cases keep them from criminal behgavior, too).
virus writers are just another kind of criminal . . .

Ok, I have to respond to some of the folks here who believe that "Don't run Outlook" is an option. Well, pray tell, what should I do if I'm on a corporate Exchange server? With no other option? It's all well and good to suggest things, but the fact is, if the Exchange Admin won't use LDAP, you're out of luck, and quite stuck.
That said, the SP2 release of Office/Outlook prevents anything from accessing your address book, and will pop up a confirmation. It doesn't prevent idiots from opening the attachments, but it does create some thought beforehand.
I can appreciate the idealism of using Linux for everything (I'm a Debian developer for god's sake) but for my job, I have to use Outlook, so I do, because I like my job, and I'm not going to quit because of that minor inconvenience.
I suppose this qualifies as a rant, and possibly will be modded to "Flamebait" or "Troll" but let's try and tolerate some dissent on this board for a change.

There is a principle in the Toyota Production System that goes something like this: "If a worker makes a mistake once, it may be the workers fault. If a worker makes a mistake twice, it is the supervisors fault. If a worker makes a mistake three times, it is management's fault".
Most human beings on the face of the earth are not technically minded and DO NOT WANT to understand the details of how the tools they use work. If every time Joe Homeowner flipped on a light switch there was a 1% chance of a nuclear power plant melting down, we wouldn't be using much electricity, now would we?
While Microsoft is to blame for creating insecure tools (keeping in mind that larger market share means more attaraction for attackers), responses along the line of "stupid users don't understand how to use e-mail" are not acceptable, either.

Bleh!
I've been using Outlook for far too long and get far too much functionality out of it to switch to another app because macro viruses for it are spreading. I've got the ultimate in Outlook macro virus protection-- it's called a BRAIN.
.vbs, yet somehow others cannot? These viruses are the tamest you could ask for-- don't run the damned script file and you won't be infected! Oh wow! True genius, I know!
First off, the only way to make macro capabilities even worth a damned was to include functionality that could also possibly be used for - *gasp* - viruses! Oh no! Shit man, big deal. Why is it that I can look at the attachments on my emails and plainly see an attachment that ends with
I certainly understand that these viruses are capable of creating better disguised files (such as spreadsheets with autorun macros), but every Office app has an option to NOT autorun macros. IIRC, this is the default option (at least on Office 2000-- havent touched XP). And beyond that, that virus started off at some point as a script file. It took some jackass who wasn't paying attention to get it going.
As well, the only reason this is even an issue is because of the number of people that use Outlook. Say someone wrote a "macro virus" for some Linux GUI mail client which supported scripting of some kind (Python, for arguments sake). It could disguise itself into other files, send random files to random people and generally spread itself just like these Outlook ones do. The only reason we'd never see news about something like that is because there arent the numbers of people using such clients that are using Outlook clients and as such, I imagine there aren't very many virus kiddies out there looking to target the Linux geeks of the world.
Now, don't get me wrong. I'm no GO MICROSOFT! guy or anything, but at the same time I realize that when it comes to them, many people on this site don't even give a second thought before finding them guilty of murder...

Why can't these virus writers do something cool? Like install the SETI@home client on every infected machine? Or install something to DOS the RIAA/MPAA/Bad-guy-of-the-week (how about having the DOS daemon check Slashdot to determine who the current bad guy is)?
I'm sure that someone can come up with even more interesting things than this...

I'm sure a lot of people here are going to go out and blame Microsoft for the Outlook-virus-of-the-week. But the fact is, Microsoft is just giving the user what they want.
Good Lord.
This reminds me, almost word for word, of statements typically made by rapists and child molesters. While the situation is vastly different (thankfully), the behavior of the guilty party, Microsoft, is appallingly similar: refuse responsibility for one's own actions and blame the victim.
The cause of these (now almost cliched) viruses is, quite simply, the appallingly lax security in the Microsoft Operating System and mail utilities, a lack of which is unequaled anywhere else in the computing world. Whether by design, negligence, or simple incompetence the fact remains: if you run any version of Windows, IIS, or Outlook, you are vulnerable to this sort of thing regardless of how savvy or cautious a user you are, and there is little or nothing you can do to protect yourself. Indeed, by the time you know of the exploit (assuming you are savvy enough to keep up on such things, which IMHO is asking far more of the user than simply learning a few basic commands a la GNU/Linux or DOS, much less a few GUI variations from with Windows paradigm a la Mac, KDE, or Gnome) chances are the malicious crackers have been exploiting it for weeks or even months.
Contrast this with the rest of the computing world, in which exploits are published and fixed as soon as they are found (and usually found by the product developers and/or testers before they are exploited), and in which the basic security paradigms allow one to secure the system in as paranoid a fashion as the situation requires, and the mind truly boggles at Microsoft's inability to at least match the quality of competing products such as Mac OS/X, the various *BSD flavors, and GNU/Linux.
It is bad enough that Microsoft appears incapable of building a secure system. It is even worse that they knowingly market an insecure and unstable system as though it were secure and stable (were there still any kind of "truth in advertising" requirements they would certainly be paying hefty fines for falsly marketing their products). It is unconscionable that they refuse to accept responsibility for their own engineering, choosing instead to blame the victims of its failure: their customers.

The problem here isn't even gullible users. It's the fact that under Win9x, you're running as god all the time, and can seriously hurt yourself. Under Linux, I can create a temporary user in about 30 seconds, go crap all over the resulting sandbox, and I *might* release a forkbomb or fill up /home... if I was being lazy. If I was really worried about it, I could ulimit the bejeezus out of the new userid, and whatever little surprises lay in that exe wouldn't get past first base.
And it's not just Linux, or other Unixes... VMS, NOS, NOS/VE, VM/CMS... IS there another OS out there that DOESN'T have proper ACL's and CPU/process limits? BeOS, MAYBE?
Yes, there are a lot of clueless Windows users. There is still no excuse for deliberate insecurity on the part of the OS. As for Microsoft "giving the users what they want"... As Norm Schwartzkopf would say, bovine scatology. See previous comment.
Actually, there is a simple cure to this, and it has even been used by Code Red: operate in two phases:
- A spreading phase, where you don't do anything malicious, except infect other machines. Best if done as low-key as possible: only attempt to infect those people that use Outlook (analize headers of recently received mails), attach yourself to documents that the user sends, rather than making up documents of your own, etc.
- An active phase, where the fun really starts: DOS the withehouse, mail out confidential
.doc files, thrash the BIOS and hard disk, etc.
The difficult part of course is timing. If the active phase starts too early, you may not have enough of an "installed base" to really wreak havoc. And if it starts too late, a cure may already exist by then.Good idea... but who assigns virus names? It was my understanding that the names under which a virus is known is usually not chosen by the author, but by the anti-virus community once it is "discovered". Thus, it would be rather hard to scan for its name, as it will not be known at the time of writing...
This isn't a problem with Outlook, it's a problem with idiot users clicking on every damn thing they're emailed.
Outlook Express, at least, has a horrible user interface for attachments. First, *any* attachment with *any* extension will trigger the dialog, which means users will ignore the dialog after seeing it several times. Second, it conveys the possible threat from the file type only by displaying the extension, and many users haven't memorized what extensions are safe and which aren't. Third, it only asks that you "be certain that [the] file is from a trustworthy source", which doesn't help much if the "trustworthy source" is infected by the same attachment.
The shareholder is always right.
This sort of trojan can theoretically be ported to any platform that has an email client and an address book.
It is exactly the same as if the user downloaded the trojan from an FTP site or through Gnutella, it's strictly an application. It doesn't rely on being received via email, all it needs is for the user to choose to execute it. Now if that application (trojan) happens to be a Linux executable, it's going to run when the user tells it to run. It's going to go ahead and read whatever address book it can find and spam everyone with a copy of itself.
It's naive to think this problem only affects Windows users. It's only a matter of time before someone creates a Mac or Linux port.
Of course, then the headline would have to be "Idiot Users Still Exist, Nobody Surprised" -- doesn't really have the same aire of panic though, does it?
Joe emails a rogue application to Jane, Jane runs the code which then emails itself (and an arbitrary document) to people in Jane's address book. Sounds like something that could be implemented on any OS, doesn't it? You can't patch user stupidity.
Anyhoo, let the Microsoft bashing begin! Everyone get your pitchforks and flaming torches, but leave your dictionaries at home.
Right. They only have to understand how to use them, and that includes understanding possible consequences of using them incorrectly.
Morale: "Messer, Schere, Gabel, Licht, ist für kleine Kinder nicht." Don't give someone who does not know how to use it, a tool that could become hazardous.
Just as an example: Today's internet is swamped by users who want to send e-mail "cuz its c00l" but probably don't know what an attachment is. They don't need to know - as long as their email client does not support attachments.. As soon as they get the possibility to send attachments, they must learn

One thing I've noticed is that it's always my work address that seems to get the viruses. In the 10+ years that I've had personal email addresses, I think I've only had maybe 2 even delivered to any account. (This includes free Outlook-enabled web accounts).
There's only a couple conclusions I could draw from this:
1) I am a supreme personal system administrator and do not let any common mundane virus issue affect the harmony of my smoothly oiled machine. (you do you oil computers, right?)
2a) All of my personal friends are apparently not as stupid as they look (this one is hard to believe).
2b) All of my work collegues are definately more stupid than they look (ok this one isn't so hard to believe). heh
3) There is some kind of shield made up of impervious virus-fighting smurfs that protect my personal computer 24 hours a day.
4) Karma (no not that kind)
or most probable:
5) Someone has been reading and deleting my personal email for years.
"It relies on the user executing the attachment, it doesn't execute itself."
Unless, of course, it's something like Javascript code, or an unruly image tag. Exploits of this nature have been discussed on BUGTRAQ (more recently as an example of how poor PHP programming can cause security problems [duh!], so don't think I'm picking on Outlook here). Any mailer that displays even plain HTML as soon as you view the message can be attacked, and ones that do Javascript are INSANE.

If you think that's bad, take a look at this virus/trojan that was floating around IRC a while back. The thing is indistinguishable from a text file at first glance, even if you're bright enough to check the extension. When it executes, it even opens a contained note in Notepad so you don't think anything is wrong.

this virus has already been spreading actively since last thursday or something...
;)
anyway, one stupid thing is that all the reports call it "privacy" sensitive because it sends out personal documents from your drive... but from all the stuff I received over the weekend, I noticed it's just the name of the document it uses... the actual content is the virus itself; an executable disguised as a document...
of course, since lots of windows users use 50% of the document contents in the name of the file, it could be quite emberassing if it picks the right document

It seems just about every damn virus nowadays spreads via Outlook or Outlook Express which is too bad
But has anybody (specially Timothy) actually paid any attention to the damn stories?
Nowhere in these stories is it claimed that Sircam uses Outlook to spread! Maybe Timothy got the idea from reading this CNN article.
Geez, people, do you believe everything that CNN says? It's not like I really expect CNN to get this right, but /. readers are supposed to be better than that!
In fact, the Wired news clearly says that the virus serves as it's own SMTP client. A lot about this virus in fact resembles how the Judge Disemboweler virus operates.
The only thing that can be interpreted as using Outlook to spread itself is the fact that it takes its e-mail addresses from Windows Address Book files; however it will also try to get addresses from some files in the 'Temporary Internet Files' folder. This means it should be able to spread without any need for Outlook (just some e-mail client and a user naive enough to run the attachment) and without Windows Address Files.
All the usual sources of virus information seem to agree about this virus serving as its own SMTP client. Please check for yourselves:

Another Nasty Outlook Virus Strikes
Score: -1 (Redundant =)
-Kef
I am a moron. I admit it - I caught this last wed. Even had Norton running. It didn't blink. The email came from a client during the day. The attachment was an excel spreadsheet that I had sent her earlier. Yes, I should have read the email and then I would have been suspicious, yes Norton should have caught it, but I open maybe 15 excel spreadsheets a day sometimes from this client. I don't read every email - or I didn't.
My personal firewall blocked their smtp program from sending - but then it attached itself to ie and ran through IE's security area in my firewall. It is set to send thru the smtp server you have setup in your mail program. It sent thru my local email. The only reason I noticed was paranoia and running netstat.
This virus can and does attack more than just outlook. I run Pegasus. If it infects an outlook machine it sends to emails in their address book, in my case it went thru the cache of IE. I had to send apologies to a bunch of tribes players. It doesn't parse emails very well as I got 10-20 obviously broken emails bounced back.
Norton would not remove it and at that time their was no mention on any site or newsgroup so I was forced to remove it myself. Hiding in the recycle bin took me a second time to catch.
If you read your email from a web client you can still get infected and it can still send out depending on your setup.
If you run an email server - you can block this virus very easily as the text comes in two flavors an English and Spanish version. Here is the text:

I don't know enough about it to determine the extent to which it can affect non-Outlook clients. I do know that, according to CNET, it does try other means of spreading as well.

For those unfamiliar with the Bliss Virus, it is/was a research virus written as a proof of concept (complete with all sorts of safety features, like an auto-removing feature) which eventually accidently was released on the net. ig the adminsitrator ran:
bliss --disinfect-files-please
the virus would remove itself from the system (good responsible code design-- it cleans up after itself).
My point is that writing viruses != computer vandalism. They usually coincide but not always. This virus we are following is pretty clearly one covered under computer valdalism (who writes Outlook viruses as proof of concept anymore anyway-- it is too easy and would not do any good). ANY virus with a payload is malicious and probably a criminal offense in most countries. This worm carries a payload, so its intents are clear.

This will not be the last time we see a Slashdot headline of this nature (and I seem to recall that it's not the first either...)
The underlying problem here is that people have come to accept executable attachments as the norm. Years of silly Flash greeting cards, "snowball fight" games, and Joe Cartoon crap sent across offices since the mid-1990's have hooked Windows users on native-binary attachments. The only way that this sort of activity can be stopped is by making it socially unacceptable (improper netiquette) for anyone to send executables through email. Think about what would happen if one of your colleagues sent you a random Linux binary through email and claimed it was a greeting card - would you run it? Well, the drooling masses will run any .exe that a "known" source sends to them, and that is the crux of the problem.
Unfortunately, it is in content producers' best monetary interest not to change their distribution strategy to use a format that requires less trust (such as .swf or even .html). That would artificially limit the quality of their goods, and closes the door to including "value-added features" (like spyware) to their attachments. Therefore, the situation shows few signs of changing anytime soon, and users will simple work around any stopgap measures in their email software so that they can continue to play their "frog in the blender games" in perpetuity.
