New variant of Android Ransomware 'SimpLocker' spotted


A New variant of the Android Ransomware known as 'SimpLocker' has been spotted by Security researchers at ESET.

This new variant has a few significant improvements including the language in which the fake warning message is written, it is now in English rather than Russian.

The malware is masquerading as a flash player for the Android and tricks users into installing it with administrator privileges .

Once the device is infected, it will show a ransom message saying that your device is locked because you were doing illegal things and demands you to pay around $300.

One of the variant attaches the photo of the victim taken by the front camera in the ransom message.  This trick will definitely scare victims into paying the ransom.

One of the worst features added to this variant is now it encrypts the compressed files such as ZIP, RAR and 7ZIP.  It means even your backup files are being encrypted by this trojan.

ESET has released a tool to decrypt the files that have been encrypted by Simplocker.  The say prevention is better than cure, so better focus on prevention - Be careful while installing apps from unknown sources.

Simplocker : First Android Ransomware that Encrypts files in Your Device

Ransomware is a type of malware that locks you out of your computer until you pay a ransom.  In some cases, it can actually cause more serious problems by encrypting the files on your system's hard drive.

Last year, Symantec discovered an android malware with hybrid characteristics of Fake AV and Ransomware. Last month, Bitdefender identified an android version of Ransomware which was being sold in the underground market.  The malware bluffed victims into paying a ransom but didn't actually encrypt the files.

Until now, there have been no reports of android malware that encrypts the files.

Security researchers at ESET say they have spotted the first variant of Ransomware that encrypts files in your Android Device.

The malware, dubbed as Simplocker, shows a ransom message written in Russian which informs victims that their device is locked for  viewing and distribution child porn.

It scans the SD card for certain file types such as image, document or videos, encrypts them using Advanced Encryption Standard(AES), and demands money in order to decrypt them.


It also gathers information about the infected device and sends to a command and control server.  The server is located in Tor ".onion" domain for purposes of anonymity.

Don't Pay:
"We strongly recommend against paying up – not only because that will only motivate other malware authors to continue these kinds of filthy operations, but also because there is no guarantee that the crook will keep their part of the deal and actually decrypt them" Researchers at ESET say. 

Be careful when You Browse Adult contents in your Android phone

CryptoLocker Ransomware which is so far making trouble for Desktop users by scaring them into pay a fine to unlock their locked hard devices is now started to target Android users.

BitDefender have identified a new mobile version of the Ransomware which is being sold by the same group responsible for the Desktop version of Ransomware malware.

The malware dubbed as 'Android.Trojan. Koler.A' is being served to the mobile devices, when the users are browsing certain adult content websites.

The malware disguise itself as badoink, a video player that needs to be installed to get premium access to porn and tricks users into installing the app.

Once installed, the malware finds the location of victims and shows a fake warning message in their local language.

"Attention! Your Phone has been blocked up for safety reasons listed below.  All the action peformed on this phone are fixed.  All your files are encrypted.  Conducted Audio and Video" The fake message reads.

The warning message informs the victims that their files have been encrypted and they have to pay $300 ransom in order to unlock their device. 

But, No Need to Panic ! The files stored on the device are not actually encrypted as the warning message claims.  By pressing Home button, you can return to Home screen. You will have 5 seconds to Uninstall the app from your device.
