You are guilty of child porn, child abuse, zoophilia or sending
out bulk spam. You are a criminal. The Federal Bureau of
Investigation has locked you out of your phone and the only way to
regain access to all your data is to pay a few hundred dollars.
That message — or variations of it — has popped up on hundreds
of thousands of people’s Android devices in just the last month.
The message claims to be from the F.B.I., or cybersecurity firms,
but is in fact the work of Eastern European hackers who are
hijacking Android devices with a particularly pernicious form of
malware, dubbed “ransomware” because it holds its victims’ devices
hostage until they pay a ransom.
Seems like some apps do get written for Android first.
