An investigation by The Guardian has revealed that Israel's Unit 8200 has developed a system to collect and store millions of mobile phone calls made daily by Palestinians in Gaza and the West Bank. This mass surveillance operation, which has been ongoing since 2021, utilizes Microsoft's Azure cloud platform, with data reportedly stored on Microsoft's European servers. The surveillance reportedly processes around one million calls per hour, accumulating to approximately 200 million recorded hours. The system has been linked to facilitating Israeli military operations in the region. The report highlights the close cooperation between Microsoft and Israel's military intelligence unit, raising concerns about the use of commercial cloud services for extensive intelligence gathering and its implications for the Palestinian population.
