Android Trojan Found in Targeted Attack

In the past, we’ve seen targeted attacks against Tibetan and Uyghur activists on Windows and Mac OS X platforms. We’ve documented several interesting attacks which used ZIP files as well as DOC, XLS and PDF documents rigged with exploits. Several days ago, the e-mail account of a high-profile Tibetan activist was hacked and used to send targeted attacks to other activists and human rights advocates. Perhaps the most interesting part is that the attack e-mails had an APK attachment – a malicious program for Android. Read Full Article

Vidro: How deep and mobile is the rabbit hole?

The appearance of a new Android malware family is not that surprising at all today.

Find and Call: Leak and Spam

Yesterday we were contacted by our partner MegaFon, one of the major mobile carriers in Russia.

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.

Android Security Suite Premium = New ZitMo

On the 4th of June 2012 we found 3 APK files of ~207 kb in size each heuristically detected by our engine as HEUR:Trojan-Spy.AndroidOS.Zitmo.a. All these applications are malicious and were created to steal incoming SMS messages from infected devices. SMS messages will be uploaded to a remote server whose URL is encrypted and stored inside the body of the Trojan. We found 3 more APK files with exactly the same functionality on 8th, 13th and 14th of June. So there are at least 6 files which pretend to be ‘Android Security Suite Premium’ but in fact were created only for stealing incoming SMS messages. Read Full Article
