The report (opens in new tab) from ESET says that the ‘Android/Filecoder.C’ malware has been active since July 12 and first cropped up on Reddit. According to the researchers, the virus is typically disguised as an X-rated online game, but can also come masked as a more PG-13 tech app.

New Android nasty emerges
If the infected .APK file is downloaded by an unsuspecting user, it then connects with a server and taps into the victim’s contact list. This allows it to start spreading itself via SMS text message in up to 42 different languages, but at the same time it’s also encrypting files on the host device so that the user can’t access them. Those who fall prey to the virus are instructed to pay a ransom of between $94 and $188 in Bitcoin. Once a transfer is received, a private key is sent allowing the victim to decrypt the locked files. The attackers threaten to destroy the files in 72 hours if the ransom isn’t paid, though ESET says its research indicates that isn’t always the case.
Protecting yourself from malware
The best way to protect yourself against malware like Filecoder.C is also the simplest: don’t download unknown files to your device. In the case of Android, this means being particularly care of where you download APK files from. Outside of the Google Play Store, this means sticking to downloading apps from trusted sites like APK Mirror. Likewise, read your texts carefully before clicking on any links they may contain. Does it really sound like something your friend would say? Do you normally use SMS to communicate, or WhatsApp? Questions like these can help you decide if there’s something fishy about the message you received.
