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]

Twitter Gets Swamped With Weekend Worms

Spring break is here, and, apparently, Twitter had a little too much fun over the weekend, waking up with a couple of nasty bugs. Thankfully, if the pieces of malware that made the Twitter rounds this weekend were STDs, they would be crabs -- annoying, but curable, and not particularly dangerous.

The first attack came Saturday, originating with a couple of accounts specifically created to spread the StalkDaily worm. By simply visiting an infected profile, a user would find her account hijacked and sending automated Tweets with a link to a Twitter-like service called StalkDaily. By the end of the day, Twitter had cleaned up most of the infected profiles, had deleted the offending messages, and had apparently plugged the security hole that allowed the exploit.

Then, on Sunday morning, a second attack hit, taking advantage of the same flaw. Oops. The new worm, called Mikeyy, simply sent out automated messages containing the word "Mikeyy," and mocked Twitter's inability to fix its vulnerability. Mikeyy spread even faster than the StalkDaily worm, and, in no time, people's Twitter feeds were clogged with messages such as, "Twitter please fix this, regards Mikeyy" and "Man, Twitter can't fix sh*t. Mikeyy owns. :)."

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]

Facebook 'Koobface' Viruses Getting Smarter, More Dangerous

Facebook Viruses Getting Smarter, More Dangerous

Back in October we reported on a virus by the name of Koobface, a nasty trickster that appeared in the form of messages pointing to supposedly racy videos. Click the link in the message and you'd be directed to download a new video player, which was in actuality the virus, itself, quickly taking over your profile and spreading to your friends. Koobface is sadly still around, now in its 28th revision, and is getting smarter and trickier, but no less annoying.

Have you ever been the victim of a computer virus?



The basics are still the same: It's still shown as a link to a supposed video that prompts you to install a new version of Adobe's Flash player, the most common format used for Web videos. These days, though, that ambush page is a lot sneakier, showing the profile picture of the user whose compromised profile got you in the mess in the first place, and making the whole scam look more genuine. If you install the downloaded file, the virus will look into the stored information on your computer from Facebook, compromise your profile, and send itself to all your friends -- likely making them a little less than thrilled with you.

Conficker Virus to Attack Southwest Airlines Web Site


Oh that Conficker virus, it just won't go away. Despite its authors having a bounty placed on their heads by Microsoft, the thing is still spreading, updating itself, and becoming even more prevalent. That spells bad news for Southwest Airlines, discovered Mike Wood, a security expert at SophosLabs. In a recent SophosLabs corporate blog post, he explained that millions of computers infected with the virus are set to start accessing, and thus attacking, the Southwest's Web site on March 13.

Have you ever been the victim of a computer virus?



When the infected hoard begins hitting the Southwest.com site, Conficker will have effectively started a distributed denial-of-service attack, or DDoS attack. The intent is to flood the servers hosting that page and bring them offline, so that anyone else who attempts to browse to that site receives only an error message.

Assuming the attack takes place, it shouldn't impact the overall ability of the airline to launch flights and handle passengers, but online check-in will almost surely be unavailable, as well as any other functionality the airline provides online. So, plan ahead, because you might need to get to the airport a little earlier than you'd like! [From: CNET News]

It's Alive: Actual Worm Crashes Man's Computer

Real Earthworm Causes Problems for Man's Computer
We've had no shortage of reports about worms lately, with the Conficker virus making its way into the core of computers around the world, spreading fear and hate, and even grounding a few planes along its way. Today, though, we present a story about a very different type of worm: a real, live, earthworm. Well, it was alive, before being killed by the heat inside a man's laptop.

Experiencing computer problems, 45-year-old Englishman Mark Taylor recently received a message stating that the cooling fan on his machine wasn't working correctly. He took it to a computer technician, who took a look inside and discovered the problem -- a five-inch earthworm that had crawled in through one of the cooling vents and, ultimately, jammed the fan. Taylor suspects that one of his cats brought the worm into the house, and that, looking for a warm hiding place, the worm made its way into the laptop. In the end, all it found was its doom, meaning that this is one worm we don't have to worry about spreading. [From: The Telegraph]

Storm Worm Reborn as Malicious Valentine's Day Greeting

Waldec -- The Second Coming of the Storm Worm
As if the threat of the Conficker hanging over our heads weren't enough, now we've got the second coming of the Storm Worm, called Waledec, to watch out for.

Waldec spreads via e-mails claiming to have a Valentine's Day greeting for you. Clicking on the link contained in the message takes you to a page containing dozens of hearts with the message "guess which one is for you? Clicking on any of the hearts prompts you to download and install an .exe file containing malicious code that spams other e-mail addresses it finds in your inbox.

Paul Ferguson, a researcher at Trend Micro, maker of anti-virus software, says he believes that Waldec and Conficker are the work of the same group. There are hints in the coding that suggest the same organization worked on both viruses.

Waldec should be a little easier to avoid than Conficker because of its reliance on unsolicited e-mails, which we're hoping you've learned to ignore by now. [From: CNET]

What Is the Conficker Virus and Should You Be Worried?

Everything You Wanted to Know About Confiker, But Were Afraid to Ask

What is Conficker?
Conficker, also known as Downadup or Kido, is the latest super virus to spread around the Internet and has security experts in a panic. When last we checked, about a week ago, Conficker had already spread to 9 million PCs, with little sign of slowing. Now it has infected at least 10 million PCs and experts believe there may be up to 350 million vulnerable computers out there.

The worm isn't just exploiting a networking hole, however; it features a sophisticated method of cracking administrator passwords, making it difficult to remove, and also copies itself to USB drives so that it can spread even when the online flaw is plugged.

What havoc has it wreaked so far?
So far this schizophrenic virus hasn't caused any serious damage. Its primary effect has been to prevent people from installing Windows updates and anti-virus software that could potentially thwart the malware. What worries security experts, though, is Conficker's ability to launch a second stage, downloading additional code that could hijack computers completely, steal personal information, or commit basic extortion -- demanding money for fake anti-virus software claiming to remove the infection.

Tricky Windows Worm Spreads to 9 Million PCs



Remember this nasty worm with multiple-personality disorder we reported on last week? Well, apparently, it is still spreading, and is now responsible for an estimated nine million infected computers! So far it hasn't done anything especially nasty, beyond finding its way onto machines, but that doesn't mean you want it lurking on yours!

Security experts at F-Secure believe the piece of malware may not be acting as the hackers who designed it intended. The firm believes that the worm was meant to give false alerts saying that malicious software had been discovered on a user's PC and then encourage that user to buy fake anti-virus software. So far, this behavior hasn't been seen, but that doesn't mean that Conficker, Downadup, Kido -- whatever it wants to call itself -- isn't leaving open a back door for hackers to steal passwords and other personal information.

Microsoft has already released a patch to battle the worm, however one of its effects is to disable automatic updates on infected machines. So head to WindowsUpdate.com, if you haven't already, to make sure you get this latest patch! [From: FOXNews.com]

Tricky Windows Worm Hits 3 Million Computers


Have you updated your Windows machine lately? If not, as always, you certainly should! Word is coming from a number of virus and malicious software experts that a certain piece of nasty software with a number of names has gone on to infect three million Windows machines around the world, with the most infected being in places like China, Brazil, Russia, and India.

The software is known as Conficker, Downadup, or Kido, but by any name, it's a worm, which is software that infiltrates machines and then spreads itself from there. This one is particularly shady and deceptive, renaming itself with every install and also connecting to random online servers, making it very difficult to detect. Once on your machine, it has the power to do whatever it likes, including steal your passwords and private information.

Have you ever been the victim of a computer virus?




Thankfully Microsoft has released a patch ensuring your machine will be safe, and most virus manufacturers can detect it. So, make with the updating already! [From: BBC News]

McDonald's and Other Big Brands Used to Spread Computer Viruses

McDonald's and Other Familiar Brands Used for Viruses
Yeah, we know, it always seems like another day, another virus around these parts, but we feel it's our duty to keep you informed of any threats to your security (ID theft, computer viruses, etc). So, we hope you're paying attention to yet another warning of a nasty virus that uses some seriously deceitful means to trick you. The latest is a series of trojan viruses that show up in your e-mail in-box purporting to be coupons, but, in reality, are just another means to install malicious software.



As seen in the above picture, one of those says it's from McDonald's and is delivering you "FREE giveaways and AWESOME savings." Actually, all it's giving is a file that, if you run it, will give hackers control of your machine and access to your data. According to CNET, similar e-mails are appear to come from Coca-Cola and Hallmark as well -- the latter even including a goofy-looking holiday card! It, too, is just another delivery means for corrupt software. So, update that anti-viral software and, as always, watch where you click! [From: CNet News]

Microsoft Releases Critical Security Patch for Windows

Microsoft Releases Critical Security Patch for WindowsAhh, another day, another major security flaw affecting millions of computers worldwide. Microsoft is the one at fault this time, with a new vulnerability discovered that impacts every version of Windows from XP and earlier, a flaw so serious the company felt compelled to break out of its usual routine of releasing updates on the second Tuesday of every month.

The flaw is in the Remote Procedure Call, or RPC portion of Windows, which could enable a hacker to run software on your machine without having to be physically close to the computer -- in other words, hackers could run software on your machine from the other side of the globe. You wouldn't even have to visit a corrupted Web page or download any software; This virus would come to you, similar to how the Blaster worm of 2003 spread... and spread. The patch fixes the issue, and you should update your machine soon through Windows Auto Update, lest you become a statistic. [From: USA Today]

ASUS Pre-Installs Computers With MaIicious Worm, Issues Recall


Uh oh. ASUS just issued a recall for all Eee Box PCs sold in Japan due to a nasty pre-installed worm. The malicious code dubbed "recycled.exe" may attempt to download additional malware while attempting to replicate itself to attached USB storage devices at the first opportunity.

Of course, this isn't the first time that ASUS has been embarrassed by its image burns. Who could forget the the illegal keygen and confidential documentation shipped on those brand new laptops last month? Apparently, only ASUS who has yet to clean house.

Valentine's Day "Storm Worm" Virus Coming

Storm Clouds
...And the Storm Worm strikes again. Like a computerized Tet Offensive, the team behind the now infamous Storm Worm uses holidays as an excuse to launch attacks on unsuspecting e-mailers. Christmas, New Year's, and now the computer criminals are prepping for an electronic Valentine's Day massacre.

The nature of Valentine's Day may make the attack much less effective. New Year's and Christmas are holidays in which people often reach out to family and friends they don't speak to on a regular basis, where as Valentine's tends to be celebrated privately by couples.

The attack is also not very sophisticated and can be easily thwarted by even the least computer savvy of users. The worm presents itself in the form of an e-mail with a Valentine's Day subject and a body consisting of a simple IP address. Clicking on the IP address takes you to a page that displays a heart and the message "your download should begin shortly." If your download doesn't automatically start it instructs you to click a download link and run the file.

The attack probably won't be as successful or as widespread as past outbreaks, but some sad lovers are sure to be infected.
