A malicious Android app that held
people to ransom has been found by US security firm Zscaler. Adult
Player appeared to offer p****graphy, but secretly took pictures of
users with the phone’s front-facing camera. It then locked the user’s
device and displayed a demand for $500 (£330) which was difficult to
bypass.
“One of the reasons for the increase is that it’s very easy to make,” said Raj Samani, chief technology officer for Intel Security in Europe. “There are people you can pay to do the work for you, and it pays really well. One group we tracked made more than $75,000 in 10 weeks.
“Apps
like this rely on the embarrassment factor. If you don’t pay, your
reputation is on the line.” Adult Player was the second example of
p****graphy-focused ransomware discovered by Zscaler. The
app was not available from vetted storefronts such as Google Play, but
could be installed directly from a webpage. Zscaler said the app’s
ransom message kept the phone’s screen switched on at all times, and
reappeared if the handset was restarted.
