Despite promising to help determine what happened with the hacks targeting journalists and activists in Italy, Israeli American spyware maker Paragon has reportedly not responded to authorities’ requests for information.

Researchers have found a new case where government authorities used a fake Android app to plant spyware on a target’s phone. The company that allegedly developed the spyware was not previously known to sell this type of software.

Italian authorities are making progress in their investigation into a wide-ranging spyware scandal in Italy involving Paragon spyware. But the mystery of who hacked two Italian journalists with Paragon spyware continues.
