What is OSX/Koobface.A?

If you've ever wondered what the heck Facebook and other security news sites are talking about when they mention "Koobface," I decided this might be a good blog entry to explain the OS X version in simple terms. Koobface is a computer worm that first targeted users of social networking sites Facebook and Twitter.

Intego’s most elite Mac Virus hunters determined the Trojan horse OSX/Koobface.A affects the Mac OS X platform, too. Someone might encounter Koobface.A from links on Facebook, MySpace and Twitter, or from some other dark corners of the inner-webs. If you're one of these unfortunate, unsuspecting Mac users, then you would be taken to a page so you can view a video, which is when the malicious Java applet loads.

As normal with Mac security, first you would be alerted to this by way of the standard Mac OS X Java security alert. Allow the malware to run on your Mac and it will attempt to download files from one or more remote servers. If your Macs have Anti-Spyware activated, which they say comes with antivirus for Mac, I know that Intego software will alert you to an outgoing connection by Java.

If your Macintosh does not have anti-virus threat filters, and malicious files are downloaded, Mac security experts say these files include elements designed to infect Mac OS X, Windows and Linux. According to Facebook Security and Intego's most elite Mac Virus hunters, there is evidence of several malware infections in the wild.

If you think you're infected, you might be asking yourself: Does my Mac have a Virus?

Credit Card Number STOLEN on the Internet?

Greetings Mac user! Has your debit or credit card number been STOLEN on the Internet? 

Check it now! 

OK, so this probably won't work on the better 99.9% of us Mac users on the Internet. The truth is most of us know how to keep our privacy on the Internet, but is smarts enough security to keep us most safe? Not all scams are so obvious to ask nicely: Can I have your credit card number? 

Lost credit cards or stolen debit card numbers are liability issues, and ID thieves do exist and they are looking for your stolen credit card number. One way for them to get your stolen credit card number on the Internet is simply to ask you, disguised as a kind, gentle (or perhaps fun) software program, completely unlike the Mac OS X malware that it is. The bad news is that this tactic has become more common on the Macintosh platform.

Mac malware code writers have become quite sophisticated and sneakier in their approach to get you to give up your credit and debit accounts. A sophisticated hackers tactic? The evil Trojan horse. According to SearchSecurity, a Trojan horse may be widely redistributed as part of a computer virus. This type of Mac malware is bad news for any Apple Mac, plain and simple, and it sucks if your computer gets infected with it. 

Using stolen credit card numbers is obviously a crime, yet criminals use stolen credit card numbers all the time. The most widely known Trojan horse for Macs is MacDefender, which Intego's Mac Virus hunters discovered in May 2011. The MacSecurity / MacGuard / MacDefender / MacShield fake antivirus (Trojan horse) worked like this: 

The best Mac security recommendation is to not give hackers a chance! But what do you do about it? Some Mac OS X users ask: Antivirus for Mac, really? Protecting your Mac and data is important, and I know of a few ways to keep you safer on the Internet and away from having a lost or stolen credit card number. There is no 100% method. However as I mentioned before, I am here to answer one question: Do we really need Anti-Virus for Mac?
