Six Japanese men have been arrested for allegedly using a virus-laden porn app to infect Android phones and swindle more than $250,000 from their victims.

The malware, which posed on an adult content site as a free video player app for Android devices, stole personal information such as phone numbers and email addresses of the smartphone users who downloaded it, the Yomiuri Shumbun reported. The infected app also launched a screen that every five minutes demanded fees up to 99,800 yen per user, (about $1,264).

The infected Android phones displayed the ransom screen even with their phones turned off. The Yomiuri Shimbun said a total of 9,252 people in Japan downloaded the infected Android app  since it appeared on the adult site on Dec. 30. Of this group, 211 people paid about 21 million yen (about $250,000) in fraudulent fees.

Of the six people arrested in connection with the scam, three are either current or former executives at information technology firms.

To help keep your phone, your identity and your wallet safe, make sure you review the permissions each app requests before you download it; if you feel the app is asking for too much access, don't download it. Also, read the user reviews to see if the app has been flagged for suspicious behavior.
