Leaked documents reveal Israel’s spy agency used Microsoft’s cloud to store Palestinians’ phone calls and target them.

Israel’s elite cyber-intelligence unit stored vast volumes of intercepted Palestinian phone calls on Microsoft’s cloud servers, according to a joint investigation by The Guardian, +972 Magazine and Local Call.

The surveillance system, operational since 2022, was built by Unit 8200, the Israeli military’s secretive intelligence branch. It enables the unit to collect and retain recordings of millions of daily phone calls from Palestinians in Gaza and the occupied West Bank.

The revelations initially reported on Wednesday stem from leaked Microsoft documents and testimonies from 11 sources, including from Israeli military intelligence and the company.

According to the leaks, a large amount of the data appeared to be stored on Microsoft’s Azure servers located in the Netherlands and Ireland, the Guardian reported.
