Yet Another Windows Worm
kraksmoka writes "MSNBC is reporting that yet another active worm is taking over computers in 115 countries today. 'Antivirus companies were on high alert Thursday after the rapid spread of a new computer worm that includes particularly malicious snooping techniques. Bugbear.B, a variant of a worm released last year, installs keylogging software, back-door software, and in some cases even attempts to control infected computersâ(TM) modems. Some of the wormâ(TM)s functions are designed to specially target financial institutions.' Yummy!"
The patch for this was out 2 years ago. No excuse.
.exe file. You should block that. No excuse.
The virus comes in as a
AV dat files have been updated already. No excuse.
We've been filtering this all day.... It's not that hard to protect yourself.
This sucker ripped through our campus like nothing. Heuristics missed it, and the definitions weren't updated until a few hours after a few hundred machines got nailed.
the annoying part is that as complex as you can make software, you can't fix the people who are morons, which is where the real problem lies.
oh well.
Yeah, because it's a lot of work to set windows to do updates automatically. Just a troll, nothing to see here.
You obviously don't administer servers with Enterprise Level Code. If you did, you'd know that with Microsoft you can't simply use automatic updates. Microsoft Service Packs break systems all the time. If you run ASP.NET and Sql Server code, you get bitch slapped everytime they release a service pack or "security fix". They consistently change functionality, without warning. Then they just post on their website (three months later) that the service pack changed the way some undocumented feature worked, but you weren't supposed to use it that way anyway, so tough shit.
Ha!! Automatic updates my ass.

...is one involving how it handles MIME types, especially within IFRAMEs. What happens is, the message headers will say it's one type, such as audio/x-midi, while the payload is really an EXE file, sometimes misidentified as a .bat or a .pif. The unpatched Outlook or OE thinks, "Ah, a MIDI file! Let's play it!" and blithely passes it to the OS, which thinks, "Ah, an executable! Let's run it!".
One more example of why HTML doesn't belong in email, aside from web bugs and other BS.
Oh, no! You have walked into the slavering fangs of a lurking grue!
This is precisely the reason why I PGP digitally sign all my email. Almost a year ago, someone on a mailing list for one of my University groups got a virus on their computer sending out spoofed email and/or virus. One of them happened to have my name (email address only) on it. I was lucky to not lose any face from it, but it was very unsettling for me. Now I can say if it doesn't have a signature, it aint mine

Just wait until:
a.) Everybody decides to hate Linus.
b.) Linux machines can be counted in the millions.
a. is unlikely. How can anyone hate free software? Oh yeah, it's putting you out of business. Microsoft does an admirable job of astroturfing congressmen and Slashdot, but they have yet to put out a good free software worm. The intersection of people with the skill to write free software worms and the number of people who hate free software is vanishinly small. Competent people like free software, get used to it. Windoze on the other hand is just about universally hated and just as easy to break.
b. Linux machines can be counted in the millions. Desktop machines. If you figure 10% of US desktops are running some form of free software, you get millions of computers. The rest of the world has plenty of free computers as well. Yet I don't see anything breaking down mutt, pine, balsa or even Mozilla's email client. AOL's windowze messenger once had a problem but only on Microsoft platforms. GAIM and others had no peoblems at all.
To sum it all up for you, nothing is as bad as the Microsoft monoculture of poor quality software. Free software is more diverse, of better quality and is universally loved.
DMCA, Hollings, Palladium. What might have sounded like paranoia is now common sense.
And once again, those of us who know how to configure our windows systems and aren't stupid enough to (a) have open network shares with no passwords and (b) open random email attachments are safe. (emphasis mine)
Please read the fucking article. Not only is the email attachment not random, because it pretends to be a reply to an email that you've recently sent to an infected person (among other tricks), but it also doesn't have to be opened, because it uses an IE exploit to run itself as soon as it shows up in Outlook's preview window.
Yeah, just imagine if something like Apache gets popular, imagine the havoc people could cause with uptimes on those OS's.
Yes, the server community is different from userland and every piece of software will have its flaws, but popularity is not proportional to the amount of worms and viruses, lack of quality is.

Pretty simple really; for Windows 2000:
For other versions of Windows, click on the link (it has instructions for 95, 98, NT and 2K; I'd imagine XP is similar to 2K but it was written in 2001 prior to XP's existence).I'm trying to find instructions for modifying the security in Outlook 2000 as well, so it doesn't do anything automatically without a) my approval at the very least, or b) me asking it to run an attachment.
If anyone has pointers/links to articles on Outlook security, please post. Thanks!
I feel fantastic, and I'm still alive.
Backdoor routine
The worm also opens a listening port on port 1080. A hacker can connect to this port and perform the following actions:
If a program was able to tell the OS that it could be shut down by programs signed by keys A, B, and C, that would suffice. You modify the PE or Elf format to include signatures. Mandatory Acess Controls can also prevent one program run by user D from killing another program run by user D.
Making users non-administrators and running virus checkers as seperate users would also prevent some potential problems. Mail clients could use IPC to pass emails to the virus checkers and get a thumbs-up or thumbs-down.
Now, as far as Palladium goes, I think there's a pretty simple alternative.
Really what I'd like to see is L4 or another nanokernel and a few low-level drivers in the frimware along with a Forth interpreter for OpenFirmware. Your firmware would be a viable but minimalist OS, where before booting you could edit the fingerprintsof PKs allowed to sign kernels. Booting would simply be playing two-kernel-monte with the firmware kernel and a signed kernel off the HD. 1 MB and 2 MB EEPROMs are cheap enough that putting a viable OS in the firmware is looking quite attractive. Imagine having a rescue floppy built into your mobo. The QNX demo floppy shows you can do a hell of a lot in 1,440 KB.
My SGI Indy firmware loads the Linux kernel directly off the HD and directly executes it. The firmware doesn't have a fully functional kernel like LinuxBIOS, but it suffices for a bootloader in firmware. It would be easy to add signature checking to the process, along with a small menu for entering/deleting PK fingerprints. If you ship with the fingerprints from the dozen most common OS vendors, 99.99% of people will not touch the settings or know they're even there, but you still get all of the integrity guarantees of Palladium. You would of course make NVRAM locked out at a hardware level durring the boot process, wich could only be undone by triggering a POST. This solution requires no new harware besides the NVRAM lockout, and the NVRAM lockout really isn't that important if you can assume the OS will prevent writing to NVRAM. The NVRAM lockout could be skipped in the first generation for the sake of easing adoption.
Like I said earlier, my SGI firmware already does most of what's needed, as does LinuxBIOS. Apple and Sun firmware is already quite advanced and I don't imagine adding the required functionality would be that hard. Really the only advantage Palladium adds over current hardware with a BIOS upgrade is DRM. Palldium also carries a lot of baggage. I would love to see AMD come out with an improved x86-64 BIOS that includes most of the bootloader along with signature checking, if not a full nanokernel OS in firmware. Hardware NVRAM locking would also be nice.

First, run Office Update so you have at least Outlook SP1 (SP2 has been out for a while, in fact). Next, add the following value to the registry:
i on s/Mail
HKCU/Software/Microsoft/Office/10.0/Outlook/Opt
REG_DWORD: ReadAsPlain = 0x01
Outlook will convert all HTML to plain text before rendering it, and turn all embedded images, etc into attachments.
Thought I'd share that little tidbit.
In recent Mozilla versions, from the View menu while in Messenger, you can choose Message Body As/Plain Text. Works like a charm...
Oh, no! You have walked into the slavering fangs of a lurking grue!
In this case, other sites that covered this week's pair of Microsoft worms first -- and they'll cover next week's first, and so on. ZDNet, eWeek, Infoworld, Reuters, the Register and others covered it first. ZDNet has the bad habit however of sliding stories that reflect badly on MS quickly off the top pages and into obscurity.
Worms like sobig and bugbear only affect products with design flaws. Brian Valentine, senior vice president in charge of Microsoft's Windows development, said it best:
In short, there's nothing you can do to improve your security except upgrade to a different client: Mozilla or Opera instead of MSIE, Eudora or others instead of OutLook, OpenOffice.org or WordPerfect instead of MS-Office. Usually by upgrading you get better functionality, ease of use in addition to stability.Beta is broken and the link to classic doesn't work. Stop wasting our time or there won't be anybody left here.
That's bullshit. You'll notice these things don't just use any old extension, they use executable extensions. If you setup your mailserver to strip .pif, .scr, .vbs etc you'll be in a much better world.
When was the last time you got a legitimate email with a .pif attachment? Never, that's when. I setup this on all of my clients networks and have yet to have grabbed a single legit email.
How is this insightful? Last I checked Mozilla's mail client (and many others) don't have any kind of scripting enabled by default. You have to click attachments to get them to do anything, and by default it asks you to Save rather than open. So even if someone clicks on it and then Clicks OK, they just saved it somewhere.
Even cookies are off by default in the mail client. And you can turn off images.
So yeah I suppose people could "try" and target mozilla but I honestly don't think there is a whole lot of damage they could be allowed to do. The stuff that could potentially cause harm is off by default and the and people smart enough to turn it on are smart enough not to execute worms and viruses!
