Simplocker – Android Ransomware Alert!

Last year, we came across a malware named Android Defender. This malware, once inside the victim’s phone, locks the device and demands a ransom to unblock it. This malware is classified as a screen-blocker type ransomware. But now, it seems like hackers have stepped up their game. A new Android malware is doing the rounds on the Internet. And it is being dubbed as the first Android ransomware that encrypts the infected device’s data and demands ransom to decrypt it. It is known as Simplocker.

What does Simplocker Look Like?

Once installed in the phone, Simplocker displays an icon named “Sex xonix,” as shown in the image below.

Android Ransomware Simplocker

What Does Simplocker Do?

– Simplocker is a Trojan horse that masquerades as a harmless application for Android devices. Once installed in a device, it displays a message in Russian. The message informs the user that his data has been encrypted and demands a ransom to decrypt it.

– The ransomware disables the Back and Home button on the compromised device, when it displays its message on the screen. This makes it difficult to uninstall it. The malware is also designed to start every time the device boots.

– Simplocker scans the SD card of the infected device for various files including pdf, doc, mp4, png, jpeg, etc., and starts encrypting them. In other words, the malware converts files, videos, music files, pdfs, text files, and images into a form that cannot be read or used by the user.

– The Trojan sends the IMEI (International Mobile Station Equipment Identity) of the infected device to a remote server. This way, the attacker can know when the victim pays the ransom.

Some Important Facts About  Simplocker

– Simplocker, currently, is only prevalent in the Ukrainian region.

– It has not been found in Google Play store.

– It demands a ransom of 260 Ukrainian hryvnias (£13) to decrypt the encrypted data of the victim’s phone.

– The level of encryption used by Simplocker is weaker compared to that used by CrytpLocker, the ransomware that targets the Windows platform.

Safety Tips to Prevent Simplocker Infection

1. Always install apps from Google play and official sites.

2. Turn off Bluetooth if not in use.

3. Install a reliable mobile security software that automatically scans apps before they run for the first time.

4. Take regular backups of your important data on your phone on cloud or external storage devices.

5. Before connecting your mobile devices to any computer, ensure that the latter is secure with a multi-layered antivirus software.

6. Avoid clicking links in unknown and unsolicited emails and SMSs.

7. Have your mobile apps updated to their latest version. And ensure that your mobile OS is updated too.

    All of we must know the fact that we must install software from legitimate sources. Use of security software like Quick Heal is recommended. People often think that why they have to invest on security software, due to cost factor, speed issue etc. but they are wrong.

    Hey, i have been using Quick Heal since 4 years now and i really like it. Recently i tried to scan my nokia lumia 625 for virus but it seems that my licensed copy of Quick Heal Total Security version 15.00 doesn’t recognize it as a mobile phone. Can u help me out??

    • Rahul Thadani Rahul ThadaniJuly 15, 2014 at 10:05 AM

      Hi Karan,

      Firstly, thank you for being our valued customer for 4 years and having faith in our products for your security. With regards to the PC2Mobile Scan feature for your mobile phone, there are some models which are near impossible to get support for due to a lack of cooperation from the OEM’s side, in this case, Nokia. The reasons for this are manifold and often cannot be found out accurately. We are constantly trying to provide support for every device that comes out but sometimes, this is not achievable without adequate support. We hope that soon enough we will be able to provide support for your specific device, Nokia Lumia 625. Apologies for the inconvenience.

      Best regards.
