      I wish Mozilla Mail had some setting for this too. It's statistical filtering is great after it's been trained, but it did me no good this morning. By the time I got to work, my inbox had over 5000 new messages. Sure, it's trained now, but I spent over an hour this morning deleting them since I didn't want to delete legit mail too.

      So how did I get 5000 new messages? I know I'm not in the address books of that many people who got infected, so this one must be doing dictionary addressing as well as address book addressing. Since my email address is of the format [first initial][lastname]@[a large company].com, and my last name is very common, I got pummelled. Maybe I should switch to a more obscure address. :)

      Don't need spamassassin for this. If you are using qmail-scanner just set your quarantine-attachments.txt in /var/spool/qmailscan/ like so:

      .exe 0 EXE attachements not allowed
      .vbs 0 VBS attachements not allowed
      .lnk 0 LNK attachements not allowed
      .pif 0 PIF attachements not allowed
      .com 0 PIF attachements not allowed
      .scr 0 SCR attachements not allowed
      .bat 0 BAT attachements not allowed

      Make sure whitespace between the columns is a tab and not spaces. Then rerun your qmailscanner db update and you're good to go.

      Spamassassin is WAY to intelligent to be feeding it filename extensions. This is a lot faster too.

      Are there any other extensions that would be good to block?

        We filter these at the mail server:

        *.com, *.exe, *.bat, *.vbs, *.vbe, *.js, *.jse, *.hta, *.wsf, *.wsh, *.shs, *.scr, *.pif, *.lnk, *.chm

        All are potential vectors.

        http://antivirus.about.com has a bigger list of suspicious attachment types. Some are document types, but others are just special executable types in Windows, such as .chm files, which are compiled help files.

        It isn't these *have been* exploited by virus writers (though many have), but rather that they *could be*, because of their nature. I would never filter all of them, but I've gotta admit after scanning the list, most of these would be surprising to me to find in an email.

    This virus is just a little variation of an older virus, but it differed enough from the older iterations so that anti virus software didn't detect it.

    NO MORE GOODTIMES!
    There's a new virus that will re-write your hard drive. Not only that, but it will scramble any disks that are even close to your computer. It will recalibrate your refrigerator's coolness setting so all your ice cream goes melty. It will demagnetize the strips on all your credit cards, screw up the tracking on your television and use subspace field harmonics to scratch any CD's you try to play.

    It will give your ex-girl or boyfriend your new phone number. It will mix Kool-aid into your fishtank. It will drink all your wine and leave its socks out on the coffee table when there's company coming over. It will put a dead squirrel in the back pocket of your good pants and hide your car keys when you are late for work.

    Goodtimes will make you fall in love with a penguin. It will give you nightmares about circus midgets. It will pour sugar in your gas tank and shave off both your eyebrows while dating your girl or boyfriend behind your back and billing the dinner and hotel room to your Discover card.

    It will seduce your grandmother. It does not matter if she is dead; such is the power of Goodtimes. It reaches out beyond the grave to sully those things we hold most dear.

    It moves your car randomly around parking lots so you can't find it. It will kick your dog. It will leave libidinous messages on your boss's voice mail in your voice! It is insidious and subtle. It is dangerous and terrifying to behold. It is also a rather interesting shade of mauve.

    Goodtimes will give you Dutch Elm disease. It will leave the toilet seat up. It will make a batch of Methamphetamine in your bathtub and then leave bacon cooking on the stove while it goes out to chase gradeschoolers with your new snowblower.

    Goodtimes will prompt your mother to call on Friday and Saturday nights for two months after you make a new girlfriend/boyfriend. It will place your wallet and keys on an obscure shelf in the basement. It will emulate your face and stare into the neighbor's bathroom window.

    Goodtimes has been linked to cancer in laboratory mice. 9 out of 10 dentists recommend Goodtimes.

    Goodtimes will make your bloomers shrink two sizes, and it will make you gain 15 pounds. If this results in a wedgie, then Goodtimes will leave a nasty skid mark.

      Everything. Aside from the concerns that trustworthy computing is doublespeak for restricted computing, even if you assume that MS is talking about the *right* kind of trustworthy computing, this virus is the latest in a well-populated freakin' pantheon of examples of their failure to be able to provide anything of the sort.

      In other words, this is one more chance to ask yourself: why should you trust microsoft?

      Side note: I've had several acquaintances attempt to commiserate with me in the last week about various windows viruses. But I don't feel the pain.

        Your firewall helps with this? What, by blocking the mail port? Or does your firewall parse SMTP and block viruses (hint: if it did, it might be called a mail filter or something)?

        Thunderbird is a good email client and a nice way to avoid the Outlook viruses that people erroneously call email viruses.

        This one has nothing to do with an Outlook vulnerability. It's an e-mail trojan horse. Unless your mail client is unabled to receive files with certain extensions, virus checks them, or executes them under a different permission level (unlikely under Windows), then it's vulnerable.

        You represent the most dangerous class of computer users - confident and uninformed.

    Let's not forget that this is a worm. It requires that a user launches the executable so it can infect the system. Let's also not forget that many users are using non NOS's such as Windows Me (I'll admit that was a big mistake, however). Users that receive this worm must actually execute it and, since there is not concept of "administrator" on many flavors of Windows (or perhaps the users are the only user of, say, WinXP and are in the Administrators group) so the worm can do whatever it wants - the user did, after all, execute it as an administrator.

    The point is - it's the user's fault! Not Microsoft's. Something like this could just as easily happen on a *nix box if the user has sufficient privileges.

    Several of the users at work on the network I manage have gotten such worms before, but because they didn't have sufficient privileges, the worms were ineffective. In most of those cases, the virus scanner picked it up anyway.

    So, if the user doesn't have sufficient privileges, some worms don't work. Sure, this one would because it runs in userland, but the user still executed it! Besides, they should have a virus scanner anyway. Again - it's their fault.

    When it comes down to it, a worm such as a this (trojan horse) requires a stupid user to execute it - so blame the user for once.

      Let's not forget that this is a worm. It requires that a user launches the executable so it can infect the system.

      A worm is a program that propagates itself over a network, reproducing itself as it goes [catb.org]. While this worm may require user intervention, there exist plenty of worms that do not (the most infamous being the Morris Worm [snowplow.org].) A malicious program that masquerades as a legitimate application is a Trojan horse [catb.org].

      SoBig.F appears to be a Trojan with some worm-like qualities. Of course, in the world of Microsoft mail exploits, the lines are blurred, but a worm is generally not a user-launched process.

      Pedantic, I know, but worms are a special interest of mine, and they generally take a fair bit more skill to create than your average Trojan horse.

    However, the large number of "Your message to xyz@zyx.com contained a virus" is filling my mail spool faster than any spammer. Seems one of my email addresses is a popular one to spoof.

      We occasionally get an important message with an executable attached. We can either let executables through and hope nobody clicks on them, or send a message back to the supposed sender letting them know it didn't go through. Deleting a message without telling anyone is not an option, even though most of those notifications aren't going to valid addresses, whether it's from Spam or Viruses.

      Those notifications are just a way for a company to save themselves a lot of work, at the expense of others. So, we take the risk so we don't have to pollute the 'net with (almost always) useless notifications. So I would say the call to admins should be tweak your filters and educate your users, and then turn off the notifications. Becasue you know the first important message to an officer of the corp that gets deleted without any notification is going to get someone fired, and they're not going to take that risk.

      I feel your pain - I'm getting swamped myself. But at least I'm getting an idea of how many viruses are going out in my name.

      As far as I'm concerned, you can blame all of this on the spammers. Look at the schedule of these SoBig releases and deactivations. I believe this is a response to more and more open relays getting shut down. These viruses are the new open relays, and the only way to stop them is to stop Spam itself - by beating the living crap out of anyone you know who buys anything from a spammer :-)

    There has been a very large outbreak here, inside the firewall this morning.. This is probably the largest that I can remember, since we do not use Outlook/Outlook express we seem to dodge the big ones. I didn't even think this looked that bad at first glance, it doesn't really try to exploit any security holes to infect the machine. What got us was that the virus scanners were just old enough not to catch this until it was too late. All it really took was one or two people opening the attachment. The new engine didn't get pushed until at least an hour after the first internal case was discovered. By then though, it had spread so quickly that many other hosts had been infected.

      ...that just because you're not using Outlook or Outlook Express, you still may be vulnerable to worms or email viruses?

      All it takes is one user to click the attachment who has an LDAP-enabled address book of the entire company, and poof! you're screwed.

      The only sensible way to kill these worms is to block them at the mail server. If you block them at the mail server, you don't have to try to train people or keep hundreds of anti-virus clients up-to-date. Do yourself a favor and set up XWall [dataenter.co.at] if you have Exchange (this is about the coolest spam-blocker/email filter program I have ever used, BTW) or SpamAssassin [spamassassin.org]/MailScanner [soton.ac.uk] if you have Linux/UNIX. This will save you a ton of headaches in the future, and won't require you to worry about hundreds of clients being up-to-date as much as focusing on whether a few email servers are up-to-date. (Block the standard Microsoft "bad executable" list [microsoft.com] and you should be fine.)

      Seriously, in the year 2003, there's no excuse for "But my 400 clients weren't up-to-date!" Block these things at the server, which is something you as the network administrator should have complete control over, and which is where the worms should have been blocked to begin with.

    There's a spam/address verificiation message I saw that other day that was pretty clever, though. Some spammers sent a reasonably official-looking letter with Citibank headers, layout, and images telling people to click a link to view and accept a new ToS, or their checking account would be suspended. The link looked something like this:

    http://www.citibank.com:A78F...(random hex crap)...A812@127.0.0.1/cgi-bin/c.pl?user=youraddre ss@yourserver.com

    So they were logging you in as user www.citibank.com to server 127.0.0.1 (changed, obviously) and sending your email address to a verification script. Damn clever.

    I know this is anti-Microsoft land but I have been searching all morning and have found nothing, so I'll ask you.

    Is there any free software that will filter attachments in Exchange 5.5 and let me block emails with attachments such as *.vbs, *.pif and so on? I have not had much luck finding out how to do this without buying Norton or some other such thing and I can't afford to do that right now.

    I know I could set up a relay / filtering box in front of it, but I don't have the time or resources to do that today and this latest virus outbreak is driving me nuts.

    My company requires me to run an Exchange server, mainly because our execs love Outlook and the calendering features. I have to run Exchange. I can't change it. I would love to run something else but I can't. Please don't suggest I do.

    Thanks for any helpful answers you have.

      There are command line utils in Exchange 5.5 that can help delete these attachments totally. Look on the installation CD for details.

      Starting with Office XP you'll see that Outlook automatically blocks attachments ending in PIF, BAT, EXE, etc. This is an absolute that can only be modified through admin policies out in an Exchange folder.

      If you are looking for this type of deal I *think* Outlook 2000 has a service pack that installs the attachment blocking.

      Hope this helps!

    I find it funny that once again a virus is being blamed on Microsoft. The only way to spread this is to open the attachment and run it. How is Microsoft supposed to stop people from opening attachements? If you use MS Outlook you are actually immune to this virus, as Outlook blocks most executable attachments. Please explain to me why a user running a file (which then opens it's open SMTP server and emails itself to people) is Microsoft's fault? This same thing could happen on Linux, there is nothing stopping a Linux user from running a file attachment. This isn't a MS problem, it is a user education problem.

    Alright Michael! Way to blame MS for a user issue.

    Seriously, there are competant NT admins in the world.

    This should be a no-brainer, but if you run MS systems and you often have problems with worms or virii:

    1. Keep your virus definitions current. This goes double for any laptop users with broadband at home.
    2. More often then not, MS has already released a patch for a security hole before a worm or virus hits. Keep your systems up to date! Again, this goes double for laptop users with broadband.
    3. If you're behind a firewall, and you really should be, Only allow outgoing SMTP from your mail server(this keeps the worm from spreading FROM your organization).
    4. If you think you don't have time to do these things, make time. You'll waste a lot more time putting out fires than you will doing some fireproofing.

I already had *.pif files blocked (I'll give any of my users a free beer if they could even tell me what a *.pif files was used for, more or less why they should be receiving it). In 2hrs a dial-up ISP in california, the University of New Hampshire, the Indiana University of Pennsylvania, Piglet.DisneyOnline.com, a verizon DSL node, and an adelphia cable modem node had all been shut down and cleaned. Soon as I recognized what was coming in, I traced the source IPs, called the contacts, and talked to their IT people. With the exception of Disney, all were quite co-operative, had their machines down with-in minutes of notification, and back up after cleaning the virus.

    The nature of these Sobig virii/viruses are that they repeatedly hit the same addresses. Take a few seconds, look at the header, get the IP, look up the DNS, get the contact name, call and explain and you'll save yourself (and countless others) a lot of unnecessary hell.

    And in other news... Microsoft announced today that, thanks to a Bill Gates Declaration From On High (tm), every line of code in every Microsoft product, dating back to the company's foundation, has magically, spontaneously, and retroactively fixed itself. This has rendered all of Microsoft's code absolutely secure and error-free. And thanks to the mystical nature of these fixes, end users and sysadmins don't have to patch their systems!

    I'm sure most people here assume the opposite, but Outlook 2002 and 98/2000 with the security update applies are completely immune to this attack. They automatically strip executable attachments. Very recent Outlook Express versions also do this, although I'm not sure this is the default setting.

    Think about how long it's been since there has been a large Outlook attack. It's been at least a couple of years. This tells me that the people spreading Sobig not only have no antivirus protection, they're using ancient and unpatched software.

    Yay for trustworthy computing.

    MS jokes aren't innovative, but can still be fun, but not as fun if they aren't trying to relate to the truth very much. Read up about trustworthy computing [microsoft.com] and learn how it is a process that has barely taken off today, but is an effort that will show up more in Longhorn, etc. DRM and NGSCB are two technologies that have a lot to do with trustworthy computing that aren't even implemented in today's versions of Windows.

    At 2002, MS said:

    "It may take us ten to 15 years to get there, both as an industry and as a society."

    Trustworthy computing is in many ways only at the concept stage this far.

    Sure, one might wonder what's making them think it will take a time period as long as an outrageous 15 years to get these things straight and one might think DRM is Bill Gates' worst idea ever, but then one should comment about this instead. This may seem that I'm defending Microsoft, although I'm in this case just being annoyed by a joke I've seen numerous times before, and that must have been made up by some uninformed person.

      No application scripting language should be able to perform in an "untrusted" mode. There is no reason for it but due to functional designs someone at MS came up it has to be there. Someone demanded that Office documents integrate into Outlook seemlessly and this is what you get.

      Attached is a perl script with my message in it. Please extract and run it to read it.

They then proceed to include the original headers which clearly show the offending e-mail came from somewhere else. They suggest, "If this virus did originate from one of your users, you may want to consider adding virus protection to your mailserver." Uh, I won't be installing their software, that's for sure.
