Computer Hijackings Increase by 50% in 2008

Computer Hijackings Increase by 50 Percent in 2008

There are plenty of malicious programs that can do plenty of nasty things to plenty of computers, but, far and away, the most common type of attack results in what is known as a zombie. A zombie is a hijacked computer that can be remote-controlled by the attacker and made to do his or her bidding. According to a recent study by security firm McAffee, there were 50-percent more zombie computers on the Internet in 2008 than there were the year previous.

The report goes on to state that a frightening 18-percent of all computers in the U.S. are infected, meaning that, almost certainly, one of the computers you use (or one of the computers your friends use) is infected. Largely responsible are malicious programs like Conficker that trick users into installing or running them and then run in the background, responding to signals sent out by zombie ringleaders. Some can exploit flaws in an application's security, injecting themselves into your computer without your ever having prompted them.

To avoid being a sad statistic, always keep your computer up to date, and always, always, run a virus scanner. [From: BBC News]

New Worm Targets Cell Phones, Turns Them to Zombies

We've covered plenty of posts on rogue botnets, which are collections of virus-infected computers that hackers use to fulfill their evil whims, usually by unleashing denial of service attacks on sites they don't like. These compromised computers are often referred to as zombies. Now, with cell phones getting smarter and more capable, the belief is that it won't be long before hackers have fleets of zombie phones at their disposal, too. Well, folks, that very thing may already be happening.

Zombie botnets are usually created by worms like the recently infamous Conficker virus. These worms spread themselves from one computer to another, usually by tricking people into downloading and installing the virus by passing it off as a video or piece of software. There's a new worm, for example, called Yxes.A (a.k.a. "Sexy View"), that's targeting some Nokia handsets. Right now, the virus only collects information about the user, including their phone number and their handset's serial number, but it could realistically do anything it wants -- including place unwanted long-distance calls.

This is only the first phone worm, keep in mind. And it infections usually only hit phones onto which you can install third-party apps, which is increasingly more phones (the iPhone, Nokia Symbian-OS-based phones, Windows Mobile phones, BlackBerrys, Android, etc). Surely, more will be coming. Unfortunately, at present, you're on your own for cell phone virus protection. But you should be just as careful when following links and downloading software there as you are on your home computer. [From: New Scientist]

Scammers Baiting Internet Users with Fake Obama Web Sites


If you receive an e-mail or visit a Web page asking you to look at BestBarack.com, JoBarack.com or TheBarackSite.com, just don't do it. According to Panda Security, an Internet security firm, scores of malicious Web sites are running a fake news story entitled "Barack Obama has refused to be a president."

People who go to the sites are asked to download a file, which (of course) is a virus that will turn your computer into a so-called zombie. What is a zombie, you ask? We've got a nice description here, but, basically, a zombie is an infected computer that can be controlled by a far-away hacker. Not nice.

Throughout the presidential campaign and lead-up to the inauguration, enterprising ne'er-do-wells used the names and images of President Obama and John McCain to trick people into downloading viruses or falling for scams.

Zombify Your Photos

http://www.switched.com/2008/10/30/danny-elfman-launches-our-greatest-fear-political-video/
Since it's Halloween, we can't help but get in the spirit with a little bit of zombie making fun.

The online photo editor Picnik has added a fun seasonal tool under effects to "zombify" an image. The steps are simple, upload a picture with one or more people in it where the face is clearly visible. Then go to the create tab and select "effects." Then you can use a slider increase the level of zombification applied.

It's all the fun of being a zombie with out all the brain eating. [From: URLesque]

Hackers Increasingly Turning Computers Into 'Zombies'

Zombie PCs Are Spreading
A plague of computers turned into zombies sounds like a plot for a techno-horror-thriller summer blockbuster film -- though it probably wouldn't be a very good one. This is no film, though, as it's happening for real: According to the Shadowserver Foundation, which tracks malicious software, computers worldwide are increasingly becoming infected with spyware and other covertly malicious software, enabling hackers to control these 'zombie' computers from afar.

About a half-million computers worldwide are estimated to be infected, and disconcertingly that number is accelerating, not slowing, as those who run these underground zombie networks seem to be consolidating their forces for greater harm. Computers are typically infected through browser exploits, such as the one recently uncovered in Google's Chrome. But the number one way many computers are infiltrated remains human gullibility -- hackers still do their best work when they trick people to download software they think is one thing but is actually something bogus.

Your best defense is to simply be careful where you surf and what you download -- and, of course, to install a virus scanner. [Source: BBC News]

Celebrity Bait-and-Switch Twitter Post Leads to Hacker Takeover

Be Careful What You TwitterThought Twitter was just innocent (and frequently inane) updates about what your friends and associates? Think again. Enterprising online criminals have apparently started to zero in on the service as a way to distribute their bogus wares.

In this case, an apparently Brazilian Twitterer posted a link to a video purporting to be of a celebrity caught in a private moment. Naturally there was no video, only malicious software to take over your computer.

Clicking on the link prompted you to install what was supposed to be a version of Adobe's Flash, said to be required before you could view the video. The app was actually a fake, turning your machine into a zombie and letting those hackers take it over, use it as part of a distributed denial of service attack. That's a rather less enticing prospect than what was promised, so aren't you glad you don't install whatever websites tell you to? [Source: BBC News]

Computers, Back to School

Hackers Using Facebook Wall to Spread Viruses

Facebook Wall Used for MalwareUsually walls are used to keep things out, you know, like the wind, or bugs, or barbarian invaders. Ironic, then, that Facebook's iconic Wall, the thing that helped to set it apart from MySpace and grab a huge share of the online social networking space, is actually being used by some to spread malicious software capable of turning your machine into a zombie, so that others with bad intents can control it and make it do their bidding online.

The "attack" is actually rather unsophisticated -- just a link posted to the wall to a site that supposedly has a video of, what else, a celebrity caught in a private moment doing naughty things with a special someone. Naturally the site doesn't have any such video, just a fake version of the Flash plugin that is actually the malware itself. You're prompted to install it to view the video and, once installed, your machine is theirs for the taking.

So, as always, be careful where you click, keep your virus scanner up to date, and only install plug-ins like that from official sources, like Adobe.com. [Source: PC World]

Kremlin Hackers Squashing Free Speech?

Kremlin Empire Attacking Rebel Sites?

Enemies of the Kremlin have suddenly found themselves under attack by hackers; their Web sites crippled under a siege of coordinated and widespread attacks the scale of which only the Kremlin could finance, they say.

The victims, which include opposition parties and independent media outlets are being hammered with Distributed Denial of Service attacks, which is when computers that have been hacked are remotely controlled and tasked with inundating a Web site with request after request after request until it the site finally blows a fuse and shuts down. The attacks being waged against these groups is sometimes a million computers strong, and is strikingly similar in nature to the attacks unleashed on Estonia early last May after a political dust up with the Kremlin over a Soviet-era war memorial. A Russian political analyst has even gone on record claiming that it's a senior associate of Russian President Vladimir Putin who's behind the hack warfare.

Surprise, surprise: The Kremlin has denied any involvement.
