Downadup Worm — When Will the Next Shoe Drop?
alphadogg writes "The Downadup worm — also called Conflicker — has now infected an estimated 10 million PCs worldwide, and security experts say they expect to see a dangerous second-stage payload dropped soon. 'It has the potential to infect about 30% of Windows systems online, a potential 300 to 350 million PCs,' says Don Jackson, director of threat intelligence in the counter threat unit at SecureWorks. The worm, first identified in November and suspected to have originated in the Ukraine, is quickly ramping up, and while Downadup today is not malicious in the sense of destroying files — its main trick is to block users from accessing antivirus sites to obtain updates to protect against it — the worm is capable of downloading second-stage code for darker purposes."

It's 2009... I can't believe we're still dealing with this crap in 2009.
You are in a maze of twisty little passages, all alike.
".. that I can't get windows apps to do what i want without crashing, but it runs teh evil viruses perfectly?"
Because there is a 100% correlation between a virus crashing and a virus writer's lost profit. With most legitimate software, a crash leaves only one practical option: keep using the crapware and hope it doesn't crash again.
Firefox doesn't let web sites access your clipboard directly. Flash does. The Flash guys consider it a feature, while the Firefox guys consider it a security hole in Flash (or at least I do).
I bet the site is using Flash.
The shareholder is always right.
while Downadup today is not malicious in the sense of destroying files
How quaint! The idea that someone might infect millions of PCs just to delete people's files is so 20th century.

The both of you should probably add "that you know of".
The reality is that Linux boxes are highly prized. Their owners frequently have high speed connections and Linux can do all sorts of fun things.
Linux isn't perfect. There have been any number of security issues that would allow a knowledgeable hacker easy access. It all depends on if you kept your systems up to date and patched, didn't set up and allow unnecessary services, had a good firewall policy with a default deny/drop stance, etc.
Linux comes out of the box now pretty secure but it hasn't always. And individual user habits can also compromise a system. Add to that the fact that one of the big ways into a system now is through add-on things like flash and such, and the knowledge that there have been kernel bugs that let user applications get root with a single command (things like vmsplice), and there is a possibility that your Linux boxes are rooted and you just don't know it.
For the record, I run Linux almost exclusively and am no fan of Windows. But people need to understand that just running Linux is not a guarantee of safety. I'm also not questioning your capabilities. It's just that blanket statements about Linux security should probably be qualified.
Why bother?
Linux is free, and it's easier to learn Linux than how to keep Windows clean.

Well of course deleting files could be crippling. Which is exactly why it would be a stupid thing for a hull breach app to do.
A modern virus/trojan/worm/etc doesn't want to be noticed. It wants to be an available node to be sold to the highest bidder. Just like a biological virus it can't spread if it kills or incapacitates its host.
Deleting files was something a virus did back in the 80's because hackers didn't have much imagination. That's not to say a terrorist organization couldn't buy the next payload and send out a "secure reformat on boot" app, but it would be a massive waste of a resource (a massive botnet is incredibly powerful/valuable tool not to be thrown away) and a foolishly indiscriminate target, even for terrorists. In any case they'd have to outbid the ordinary criminals who want it to spam, hijack, DoS, keylog, skim and blackmail.
You really don't get out much, do you.

It doesn't matter how bad and unsafe Windows is. Microsoft Windows is like the air. People are going to keep breathing it no matter who farted in the room. People live in the most polluted places because that's where they live, that's where they work, that's where they play. I could tell you all day long about this other place... with clean air, that's safe, that's stable and all that... and most people might be intrigued but very few will vacation there and even fewer will actually move there. This is how people work.
Linux needs an Apple logo before the masses will move to it.
