They extorted money after the personal details were compromised
Japan was the scene of a high-profile malware incident, resulting in the arrest of six individuals (including two IT executive and one former tech executive), reports TechEye.
They were arrested in connection with an Android malware campaign, which stole more than $265,000. An incident of this sort is the first that has happened, landing the perpetrators in jail. The app disguised itself as a video player & circulated through an adult website. Presumably offering adult materials, the app, once installed, stole users’ personal information, including email addresses & phone number. These were then stored in a server outside of Japan.
After the data was stolen, the app would display a message, demanding a payment of $1,260 per person, every five minutes.
The app was, however, not distributed through the official Android app store, Play. Only third-party sites were believed to have them.
