Find and Call: Leak and Spam

Yesterday we were contacted by our partner MegaFon, one of the major mobile carriers in Russia. They notified us about a suspicious application, which was found in both the Apple App Store and Google Play. At first glance, this seemed to be an SMS worm spread via sending short messages to all contacts stored in the phone book with the URL to itself. However, our analysis of the iOS and Android versions of the same application showed that it’s not an SMS worm but a Trojan-Spy that uploads a user’s phonebook to remote server. The “replication” part is done by the server – SMS spam messages with the URL to the application are being sent from the remote server to all the contacts in the user’s address book.

OS X Mass Exploitation – Why Now?

Market share! It’s an easy answer, but not the only one. In 2011, Apple was estimated to account for over 5% of worldwide desktop/laptop market share. This barrier was a significant one to break – Linux maintains under 2% market share and Google ChromeOS even less. This 15 year peak coincided with the first exploration by the aggressive FakeAv/Rogueware market targeting Apple computers, which we discovered and posted in April 2012 and later in May 2011, which no longer seem to be such an odd coincidence. Also, the delay in Apple malware until now most likely was not because Apple exploits were unavailable, or because the Mac OS X system is especially hardened. Read Full Article

SabPub Mac OS X Backdoor: Java Exploits, Targeted Attacks and Possible APT link

we can confirm yet another Mac malware in the wild – Backdoor.OSX.SabPub.a being spread through Java exploits. This new threat is a custom OS X backdoor, which appears to have been designed for use in targeted attacks. After it is activated on an infected system, it connects to a remote website in typical C&C fashion to fetch instructions.

Are Mobile Advertisers Getting Too Aggressive?

Many of the apps we enjoy are free. Well, to call them free is a bit misleading. You pay for the apps by looking at advertisements. This is a platform we should all recognize from the sidebar of Facebook, or Google, or almost any service that doesn’t charge a premium to use it. Advertising has paved the way for many services to gather a huge audience audience and still profit. Read Full Article

The Top 10 Security Stories of 2011

As we turn the page to 2012, it makes sense to sit back and take a look at what happened during the past twelve months in the IT Security world. If we were to summarize the year in one word, I think it would probably be “explosive.” The multitude of incidents, stories, facts, new trends and intriguing actors is so big that it makes it very hard to crack into top 10 of security stories of 2011. What I was aiming for with this list is to remember the stories that also indicate major trends or the emergence of major actors on the security scene. By looking at these stories, we can get an idea of what will happen in 2012. Read Full Article

What to Do About Carrier IQ

Is .info the new .cc?

In April, the .co.cc and .cz.cc sub-domains were absolutely littered with malware distributing web sites, and the unusually telling DNS registration setup on .co.cc and .cz.cc had forecast the previously upcoming Apple FakeAv. That DNS setup later led to FakeAv downloads for the Mac as forecast. But FakeAv distribution has been steadily declining since the beginning of the year, and a few related major events have occurred over the past six months. Blackhole operators have migrated to .info domains, along with other related malicious site operators. Have they pushed .info to become the new .cc?

Sweden is under attack – mass infection and new exploits!

In September we saw a 3700% increase in JavaScript-based redirection scripts, specifically Trojan.JS.Redirector.ro. This malicious redirector went from 908th place to 15th place in the list of the most detected malware in Sweden in one month. This code only redirects users to another URL, and I thought it was strange that we did not really see an increase of detected malware in September? Read Full Article
