Bugbear Windows Virus Making the Rounds

lysurgon writes "CNN.com is reporting that the "BugBear" virus (Windows/Outlook only) is spreading quickly. Unlike ILovYou-type viri, instead of deleting files or just propagating itself, this animal disables firewall software and opens a port to receive remote commands. The article doesn't draw this conclusion, but this effectively sets up slave machines for DDoS uses. Also worth noting is the puzzlement of anti-virus guys as to why they haven't been able to make the virus spread in the lab. "One of the theories is that this requires an Internet connection in order to spread." Gee, you don't say?"

The main difference between legitimate traffic and the viral traffic is the lack of a broadcast bit (real ms network traffic will be sent broadcast, the virus sends machine to machine), and a source port of 1024-1030 rather than 137.

      We had one get into our network. It didn't disable NAV on the machine and it was pretty easy to remove (just clear out the "Startup" folder in %root_drive%:\Documents and Settings\%username%\Start Menu\Programs, reboot and backup to a known-good registry. You keep a known-good registry backup, right?... If not, delete any keys in HKLM->Software->Microsoft->Windows->RunOnce)

      Also, run Task Manager and kill-9 (or whatever the Windows equivalent is) any random 3- or 4-letter processes after you've cleared the Run Once keys and Startup folder.

      I think the executable is printing its own binary when it tries to infect a printer.

It is a pretty interesting read on what it does. It seems to be a klez variant with some extra functionality. So like klez it trys to disable antivirus software and it has added more processes to kill read symantec read on it. Though I believe sometimes symantec overstates virus threats, this one seems to do a lot in a little package.

      The keyboard logging and the open port 80 makes it very interesting to see if it is waiting for a cracker to come along or if it is waiting for other payload from another infected machine or from a variant.

      It is written in the Microsoft Visual C++ 6 programming language and is compressed with UPX v0.76.1-1.22."

      "The third thread that the worm creates is a backdoor routine. It opens port 36794 and listens for commands from the hacker. The commands permit the worm to perform the following actions:

      Delete files.
      Terminate processes.

      Copy files.
      Start processes.

      Windows version:
      Memory information:
      Local drives, their types (e.g., fixed/removable/RAM disk/CD-ROM/remote), and their physical characteristics

      List network resourses and their types, and deliver the list to the hacker.

      If the operating system is Windows 95/98/Me, the worm attempts to obtain access to the password cache on the local computer. The cached passwords include modem and dial-up passwords, URL passwords, share passwords, and others. This is done using an officially undocumented function-- WNetEnumCachedPasswords--that exists only in Windows95/98/Me versions of the Mpr.dll file.

      One of the commands permits the Trojan component to deliver data using HTTP port 80. The results of the backdoor activity may be represented in the form of HTML pages. This gives a hacker a convienient way to browse the compromised computer resources.

      The fourth worm thread replicates across the network. To do this, the worm lists all of the resources in the network. If it locates open administrator shares, it attempts to copy itself to the Startup folder of the remote computer. This leads to the infection of the compromised network computers as soon as they are restarted.

      Because the worm does not properly handle the network resource types, it may flood shared printer resources, which causes them to print garbage or disrupt their normal functionality."

Out of the box, Outlook XP requires you to screw around to shoot yourself in the foot -- it warns you when you try to open an attachment, it'll tell you when there's possibly malicious script in a message and not let you view it in the preview pane, and so on. In short, you actually have to take action to get infected by a virus if you're using Outlook XP.

    There are a number of bits of that page that make it clear that the author doesn't actually know Latin.

    And we certainly don't grab for genitive singulars for the plurals when we've started out with a nominative.

    Except that viri (from vir, mentioned just above) uses the same thing for the genitive singular and nominative plural, as do all regular 2nd declension masculine nouns that don't end in -ius. For that matter, spoken English doesn't normally distinguish the singular possessive from the nominative plural (written uses an apostrophe, which doesn't affect pronunciation).

    As far as how such a noun should work in the plural, there's a perfectly good example: cetus (whale) has a perfectly normal plural ceti, following the masculine pattern despite being neuter, just like virus.

    On the other hand, the plural of virus is not attested in any form. The logical conclusion of this fact is that virus is a word like "sheep" or "fish", which doesn't have a distinguished plural form. It makes more sense, anyway, because you're not generally dealing with individual copies; you're dealing with an infection as a whole.

    Of course, if you really want a plural that's obviously a plural and refers to multiple different entities, use "worms".

    It's been a bad day, so - ::begin true it-happened-to-me BOFH-style rant:: ::Sorry for the length, but I feel better now::

    Yanno, I've been telling my users for years now that the easiest way to stay safe is to keep updating. I even (choke cough sputter) turned on "Automatic Update" in Windows, just so it would keep them up-to-date. They disabled it, claiming "Every once in a while things would get slow for a bit, but now it's fine" or my favorite "I got funny messages". (PS: Also had to reimage 7 machines because somebody decided he was a geek and he could just copy his registry between machines).

    So I capitulated, and started sending everyone reminders by email when they had to update. I included the URL to windowsupdate and copious instructions. "It's too hard, I don't know what to do", they whined. I tried sending them the enterprise update exe's. They downloaded them, alright... put them right on their desktop, and forgot about them. I rewrote the reminder emails to include a script to do everything for them. It worked, for a bit... then I started noticing machines not being updated, and virii floating around that shouldn't. Turns out they'd started sending my emails right to the trash. "It didn't seem to do anything", they said, "it just popped up some box and then went away, so I figured I didn't need it." The box, of course, said "PERFORMING AN IMPORTANT UPDATE ON WINDOWS, PLEASE WAIT."

    Exasperated, I set up the NT login script to push the updates to the user (which I'd been avoiding, it involved actually getting the NT server working). It seemed to work fine, until one day I browsed the network by accident (hit the wrong button), and noticed that I had 65 computers in the group in an office of almost 200. Turns out some genius had found his way into Network properties and changed the setup to skip login to the NT server. "It was really annoying", they said, "I'd start up my computer in the morning, and then I'd have to wait for, like, a whole minute or two! Sometimes it wasn't even done when I got back from getting coffee! This is so much easier, we just hit 'escape' when the login screen comes up. Why didn't you do this in the first place?". It was at this point that I found out no-one was using the network drives either ("We have a network? Like an internetwork?"), thereby rendering pointless my copius virus scans and backups and RAID setup that I'd blown my monthly budget on. Fine, I say to myself, I'll show these buggers.

    So I set up a dummy machine, with which to do nothing but keep running perfectly and with all updates and latest drivers installed. I burned a bootable CD image from it, and whenever someone called in with a virus complaint, I'd go to their machine, pop in the CD, reboot, and go for an extended coffee break. The image had a boot virus scan to clean everything else up. Happy, was I, as I noticed the drop in virus calls. Soon, they dried up. I was actually starting to feel good, untill one day the VP called me in to find out why we were sending no less than 9 different virii to our clients every day. Their excuse? "When you did that thingy with the thingy, it made all our games disappear, and I've almost gotten to the second level!" Yes, indeed, they were just ignoring the virii now, even though they were getting messages from the antivirus program. Seems they believed clicking "Quarantine" would mean that I'd take their computers away and lock them in the server (clean) room for a while.

    So I tried locking down with PolEdit and SysEdit. They brought in their own windows CD's and reinstalled, because "something was broken and it wasn't letting me do what it used to". I pulled the CD drives (no use for them here anyways, except for games), and came out of the IT room late one night to find one of the file clerks studiously pulling hard drives from the cases to reimage at home and return the next morning. I drilled holes in the side panels and put a padlock on them. The users started bringing in laptops to do their work on from home, which even made the problem worse. I screamed bloody murder, demanded to know what the source of these problems were. Everyone played dumb. I felt my brains rotting and leaking out of my ears.

    Then, salvation. The VP mentions that he's seen alot of people emailing lately, and he wants to make sure that it's all company business. Would I monitor employee email usage, he asks? I try to suppress my snoopy-dance of joy as he gives me the escape clause from the moral dilema I'd been facing about finding out what the problems were. I monitor, I read, I find out who's sleeping with who (including a schedule for a tryst in the closet behind my server room. I consider installing a hidden camera), but most importantly, I find out the source of my headaches. An industrious middle manager has discovered the joys of wholesale computer warehouses, and has been joyously selling the employees games to play at work, and later, the laptops they brought in. I wonder how exactly he managed to charge people $25 to "upgrade their L4 cache so their games go faster". I admire his inginuity, but I know he must go. I feel good about this decision, mostly because I know he's screwing around with my computers, but also because I can justify it as "doing the best thing for the company". That, and productivity has gone in the tank, and everyone is blaming their computers, and at his direction, me. I'll make BOFH yet, I tell myself.

    That was a long time ago, at least in computer years. Once he left, things bounded back up to normal. People started doing what they should, not avoiding security so they could play games all day long. Why do I tell you this long story? Because that is my experience with users, and that is the pain that is caused when they don't do what they're told to. So, as someone who's told users for years to do their updates, I feel no sympathy for users hit by this particular (and moderately ingenious) virus. If they were good users, they would do their updates like their SysAdmin tells them to. They are bad users, users like the ones from above, and so I say "No PC for you!". I wouldn't feel like this, except the story specifically states that this virus takes advantage of known vulnerabilities. I don't see it as a bad thing, I see it as a chance to see who listens to me, and who'll get "upgraded" to a new 486 next month. I'm in a BOFH mood today, can you tell?

    In closing, I reflect on my outing of the middle manager. I printed out his more venemous emails regarding me, along with copies of invoices for illegally imported computer components and computer games charged to his expense account. I wrote a touching resignation letter for him to sign, explaining how he was leaving for "personal reasons". I left these on his desk as he was out to lunch, pointed his desklamp at them, turned it on, and turned off the room light. On top, I left a short note:
