Android phone users are warned about a new strain of malware that encrypts the data on the phone … then demands payment to unlock it.
Once the device is infected with the Simplocker malware, it scans the phone's SD memory cards for certain files, including images, PDFs, audio files and other documents. When the scan is complete, Simplocker encrypts the data so that it cannot be viewed or edited until the user agrees to pay to have it unlocked.
The ransomware demands a payment equivalent to decrypt victims' files, not dissimilar to Cryptolocker – the widespread Windows ransomware that is currently the subject of global warnings.
How to protect your Android device and data from malware
– Install applications only from official app stores such as Google Play.
– Make sure you install a reputable internet security program to scan all new apps automatically before they run for the first time.
– Regularly back up all of your data on your phone, either manually or by connecting to a PC which you know to be free from malware.
– Ensure you are running the latest update of Android available to make sure you get the latest security benefits.
– Treat your smartphone like a PC: never click on suspicious links or download unsolicited attachments.
– If your smartphone or computer becomes infected with ransomware, do not be tempted to pay the ransom as there is no guarantee the cybercrimnals will unlock your data – instead seek professional IT advice and report it to Action Fraud.
If you have lost money or information – or your mobile device or computer has been taken over by a phishing or malware attack – report it to Action Fraud at www.actionfraud.police.uk or by calling 0300 123 2040.
