Malware designed to infect Macs too

Friday, July 31st, 2009

malwareQuite often Mac users operate under the assumption that they are immune to viruses and malware attacks.  The truth is, Mac users make up a smaller percentage of overall users, constituting a smaller target, and thus yielding a smaller reward to the attacker.  That is not the same as being bullet proof.  Additionally, Microsoft has continually drawn the fire of the hacking community much more often than other companies offering operating systems and applications.  This has fostered a false sense of security in the Mac user community.  Malware can be written to infect anything, including phones and other handheld devices. 

Our position is that users should be vigilant, regardless of their choice of computing platform.  Patch your systems often and beware of the sites you visit and the offers/warnings you click on.  Below is an example of a website designed to lure in visitors.  Once there, they are prompted to take an extra step in order to play a video.  This is a common action for many sites, but this particular one uses the user action to launch illicit code.  It isn’t only the promise of nudity that is used as a lure for users, so don’t get caught up in being judgmental of the intent of the user visiting this site. 

“Hackers have created webpages claiming to contain the notorious Erin Andrews peephole video in their attempt to infect Mac and Windows computers. It’s no surprise that when news broke that a voyeur had secretly filmed her through the peephole of her hotel room door that the internet would be abuzz…

… If you visit from an Apple Mac we identify the malware as the OSX/Jahlav-C Trojan horse. Windows users are also at risk (I almost didn’t need to say that, did I?). When we tested it on a Windows computer we saw it serving up Mal/EncPk-IF on occasions, and at other times rogue anti-virus product Mal/FakeAV-AY.”

Top 5 Tips to Safeguard Your Computer

Tuesday, June 30th, 2009

1. Be very very afraid! – Don’t trust a link because you know the sender, read it. Does it make sense? If not, try and get to the linked article by manually browsing to the domain. If it was a phishing scam you’ll never find what the email promised.

2. Be very very prepared! – Install software or subscribe to a managed service that can handle virus and malware.

3. Be very very up to date! – Verify that you are patching Windows, and updating your virus and malware definitions.

4. Be very very thorough! – Scan, scan, scan, and then scan again. Make sure that you are aware of what’s been found on your computer then clean it off.

5. Be very very aware! – Don’t go to a site you’re unsure of. Don’t blindly enter your information online without being certain of their privacy policy. You should always be aware of how to remove your information before supplying it.

How risky are you?

Tuesday, June 30th, 2009

shark_waveOne of the most common internet related questions we get at StoneHill, is “Which sites are dangerous?” or “How do I know if a site has spyware or viruses?” It’s a tough question and one that may never have a complete answer. That being said, we have found some the most dangerous search terms in the entire internet. By far the most dangerous search terms you could use would be “free music downloads.” Searching for that phrase seems to put around 20% of web surfers into the hands of websites that distribute malicious software, also known as “malware.” We all love free things but searching for the anything coupled with the word “free” is also one of the most dangerous searches in terms of malicious results.

The study that our researchers found examined 2,600 popular keywords on five major search engines — Google, Yahoo, Live, AOL and Ask — and analyzed 413,000 Web pages. The categories that had the highest risk of run-ins with malware: screen savers, free games, work from home, Olympics, videos, celebrities, music and news. The riskiest specific terms are: word unscrambler, lyrics, myspace, free music downloads, phelps, game cheats, printable fill-in puzzles, free ringtones and solitaire.

When we saw the results of the study, we all scratched our heads and noticed those terms and categories that were the riskiest were definitely not risque. This certainly points to the level of sophistication and social engineering that is going into luring users to these malicious sites. It may explain how your grandma got that virus; she searched for “word unscrambler.”
