Android Simplocker Holds Files For Ransom

First things first.  You should update the software on your Android phone.  I’m not talking about your apps.  Update your Android Operating System.  It doesn’t cost anything to stay up to date.  If you keep your Android OS updated then you are far less likely to fall victim to these malware nasties.  This goes for Apple iPhone owners as well.

Simplocker is similar to the Cryptolocker malware I discovered last year on a workstation owned by a local client.  Luckily for them, the computer didn’t host any files and the network had not been compromised.  No ransom was paid and the PC was reinstalled.  Crisis averted.

Now, just months on the heels of the alarming news of a malware that infected Windows PC’s and held the files for ransom, comes more bad news.  Android phones (that have not been updated) are vulnerable to Simplocker, which will scan your SD storage card for common files including pictures, documents, photos & videos.  Simplocker then encrypts your files and tells you that you must pay to regain access.

The ransom note isn’t as high as the Cryptolocker demands, but one thing I noticed about Cryptolocker was that the ransom increased as the malware successfully infected more and more devices.  Files with a type extension of jpeg, jpg, png, bmp, gif, pdf, doc, docx, txt, avi, mkv, 3gp, or mp4 are encrypted using AES.  Find out more here & here.
