New Massive Botnet Building On Windows Hole

CWmike writes "The worm exploiting a critical Windows bug that Microsoft patched with an emergency fix in late October is now being used to build a fast-growing botnet, said Ivan Macalintal, a senior research engineer with Trend Micro. Dubbed 'Downad.a' by Trend (and 'Conficker.a' by Microsoft and 'Downadup' by Symantec), the worm is a key component in a massive new botnet that a new criminal element, not associated with McColo, is creating. 'We think 500,000 is a ballpark figure,' said Macalintal when asked the size of the new botnet. 'That's not as large as some, such as [the] Kraken [botnet], or Storm earlier, but it's... starting to grow.'"

Auto-update is really annoying, especially if you don't have a very good connection. Its one of the first things I disable when I do a fresh install of XP.

Here, let me turn it back on for you. There. Don't bother thanking me, I've already debited your bank account for my time.

It would be so easy.

[Surreal Puppet]

Every time i see one of these high-yield Windows remote execution holes, I'm tempted to couple a timed network-stack-erasing payload to it (24 hours should be enough for it to be able to infect through vpn-connected laptops and such) and send it cracking. Then i always begin to wonder why this hasn't been done already; is the combination of narcissistic recklessness and technical competence really that rare? It could be argued that it's more fun to play pranks and infiltrate corporate and government networks, but we don't even see things like that (I know it was more common up to the early 90s, when the "criminal prankster hacker scene" still existed outside of small tight groups...)? Or do people just cover it up? You sysadmins out there, have you ever had anything like that happen to you, or anyone you know?

Welcome to the 21st century.

Unlike the 90's, viruses aren't typically coded for the purpose of doing as much damage as possible. Between eBay, Paypal, Amazon, and the other major e-commerce sites, the internet is now worth hundreds of billions - even trillions - of dollars every year. Dollars that would be lost if it went down or that can be stolen by the boatload. By and large, the motive for hacking - including the use of botnets - is all money driven these days. The two most common attack vectors are to either hold a site for ransom, threatening to take it offline via a Denial of Service attack if a certain mount is not paid or to simply use the masses of drones to slow down anti-phishing efforts by distributing the fake page across hundreds of bots (after all, you can run a web server using 500k of RAM and 200k of disk space, plus space for the pages, i.e. a Paypal clone takes up about 5MB on a drone.)

Judging by the size of this one, I'm going to guess its use will be the former rather than the later. 500,000 bots, all launched, say, the week of Christmas, would do a LOT of damage. Many of those systems will be corporate boxes and nobody will be sitting at them to monitor or notice anything, meanwhile a site that offers "last minute" shipping could be taken offline at the...well...last minute, costing them billions in lost sales. $10 mil would be a small price to pay to avoid that.

So yeah, it was more common in the 90's, but hacking solely to cause damage isn't something done any more. At all. The only people doing that would be, for example, if the Chinese were trying to crack a US State Department or Pentagon system (using the drones for brute force remote login attacks). That happens, but even there, the intent isn't to harm the systems, but merely to gain a valid login so you can steal information. This goes on in the corporate world too. After all, don't you think Ford would be willing to cough up $2 mil if someone could hand them a copy of Toyota's future business plan right now?

It's not so much that there aren't people who want to "just cause damage" but rather that those people grew up and realized they could make a lot of money by NOT damaging the systems. They needed jobs and there aren't a lot of positions available for someone with a skill set that includes brute forcing SSH logins. The generation that has come since them, mine (I'm 21, but I have friends who are 18 and 19, and we see each other as about the same) doesn't generally posses the level of skill of those who came before us. Sure, I can crack SSH and brute force NT Hashes with the best of them, but if you sit me and my 60 year old uncle both in front of a binary disassembler only he will know what he's doing, and finding the kind of flaw needed to make this massive botnet will require a very intimate knowledge of one.

Sorry, the script kiddies that bring the world to its knees have grown up and they refuse to work without pay.

There's no profit it in.

Pretty much. The closest was the "I Luv U" email which overwrote media files.

Since then, it's all about profit. Why destroy a computer when you can use it to send spam?

If you want to be really cruel, your "virus" would randomly alter a few numbers on any Excel spreadsheet it could access.

[FunkyRider]

Reminds me an ancient joke:
Windows is same as whores: They both have massive hole and full of viruses.

Dial up users.

[aywwts4]

Indeed, my father in law is stuck on dialup, and wondered why his computer was so slow. (I hadn't been supporting him previously so I didn't look at his patch status) A quick speedtest (20 minutes later) showed he was downloading at less than a kilobyte per second.

Thats when I noticed it was downloading SP2 every single time he connected to check his mail. It has probably been downloading SP2 since it came out, years prior.

I think he was almost 70% complete with sp2 it probably would have been done in another year of intermittent use, but not before sp3 came out ;)

I now give him service packs on CDs

Re:Go vigilante

[alohatiger]

ISP action is definitely appropriate. If they can tell who is using torrent software, they should be able to tell who is sending spam and which machines are part of a botnet.

Filtering/quarantine at this level is like shooting down a scud missile on the way up instead of on the way down.

Not sure why this was modded funny, as this seems to be far and away the predominant mentality of windows users...

Re:Idiots

Which this particular patch qualifies as.

"Some think they know better what updates to install than Microsoft suggests."

When updates stop breaking other software, and Microsoft stop bundling DRM as 'critical updates', then I suspect people will start trusting Microsoft to tell them what updates to install.

Personally I like to see what Microsoft are doing to my computer before I install it.

Re:Idiots

[Hal_Porter]

I don't know why people complain about Genuine Advantage. If you buy the software it is unlocked. If you pirate it it will still work, even though it knows it is pirated, but it won't work 100%. I.e. pirate copies are partially locked.

Genuine Advantage would be better if they had a sense of humour about it. Like instead of black screening pirate copies they could shrink the desktop slowly surrounded it by a dirty border and have photorealistic DirectX 10 cockroaches in the border. When you unlocked the workstation they'd scatter, but you still see the odd leg or antenna poking out from the edge of the monitor. Every so often one would run across the screen when you were hard at work. Hell, maybe you'd let people crush them with the mouse pointer but it would leave a nasty yellow blob on the screen. The longer you held out against buying a license, the more bold the roaches would become, and the more hit points they would have.

Essentially Microsoft discovered a way to make people RAGE! by accident with Clippy. They should put that knowledge to use annoying pirates and making everyone else laugh at them. Most people have a fear of being mocked for being cheap, they should put that fear to use.

Re:Idiots

[Architect_sasyr]

Whilst I happen to be highly entertained by your idea about GA I should like to recount a little story:

Fully registered and licensed domain of XP machines (~60 or so). Update Windows Genuine Advantage. 58 of them claim to be pirated and cease to work at any level that can be considered acceptable for a corporation.

Stories like that are why people complain about GA.

Re:Analogy

[NicknamesAreStupid]

What if I buy a rosebush and plant it in my garden, then somebody uses it to deface little kids and old ladies with its thorns? Am I kinda liable for that?

Is a computer more like a gun or a rosebush? I guess that depends on whether it is running Windows or Linux.

Re:Idiots

[mixmatch]

Why should corporate customers have to call up Microsoft every time they fuck up Genuine Advantage? Activation/IP protection schemes are hugely hated for the very reason that they don't bother the pirates but they do hassle the paying customers. Its great that you have time to play around on your pirated laptop copy, but come back when you have a bottom line to worry about.

Re:Analogy

[Bane1998]

Computer to 'Some simple concept' analogies are stupid as hell. Get over your elitism. Most people don't understand the first thing about computers, and they don't have to. Just like most people use a TV, VCR, whatever, without any clue how it works, they just use it to play movies. Blinking 12:00.

Your analogy fails because leaving a gun out is gross negligence. It's a dangerous thing, and that's fairly obvious. A computer isn't. I suppose an argument could be made that computers are dangerous. It would be quite a stretch though. In that case there should be mandatory licensing to operate one, you know... like a car. But there isn't. So, either make the argument that computers are dangerous and should be controlled (and make sure you understand the actual ramifications of that argument), or stfu and realize that no, most people don't understand Computer Security or why it's important, and they never will.

And then, as an expert in the field, learn that you aren't smarter than mom and dad using their computer, you just have a specialized skill set. Most nerd kids like prolly half the slashdot crowd are or were.. started out with computers coming naturally to them. It's easy to assume then that it shoudl come naturally to everyone. And when you see it doesn't, your first reaction is that something is broken in them. After that nerd grows up a bit in the world, that person learns that no... they aren't idiots. We just have an aptitude for something that others don't. And that doesn't make them dumb. They probably have skills we don't. Say... socializing for example. So my guess is your (and all those who always come to slashdot posting the same song and dance) maturity level hasn't quite evolved yet.

And to not be elitist myself... I can admit I was once the same way. I grew out of it, as will you. :)
