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 company has said an internal review found “no evidence to date” that Azure or its artificial intelligence (AI) tools were “used to target or harm people”.
The revelations come after the United Nations special rapporteur on the situation of human rights in the occupied Palestinian territory, Francesca Albanese, issued a report mapping the corporations aiding Israel in its occupation and war on Gaza.
