Israeli intelligence using Microsoft servers to store intercepted phone call data

ISRAELI INTELLIGENCE IS USING Microsoft’s cloud service to store recordings and metadata from millions of intercepted telephone conversations placed by residents of Gaza and the West Bank, according to a new investigation. The investigation was jointly conducted by British newspaper The Guardian and Israeli weekly magazine Sikha Mekomit (Local Call), which published it last week.

Citing conversation with 11 sources from Microsoft and within Israel, the investigation reveals that Israel Defense Forces (IDF) Unit 8200 is the primary force behind the interception and data storage project. Operating under Aman, Israel’s military intelligence directorate, Unit 8200 is responsible for collecting signals intelligence (SIGINT), cyber warfare, and code decryption, among other tasks.

Israeli security sources cited in the report explain that the commander of Unit 8200, Brigadier General Yossi Sriel, approached Microsoft because the Israeli intelligence unit lacked enough storage space and processing power to store “billions of files”. General Sriel has led a large-budget project that has significantly expanded the scope of information-gathering on Palestinians and has integrated various databases.

In November 2021, an meeting, described in the report as “extraordinary”, took place at Microsoft’s headquarters in Seattle, Washington. On one side were Microsoft Chief Operating Officer, Satya Nadella, and other company executives, while on the other side were General Sriel and other senior officials of Unit 8200. The agenda centered on a plan, promoted by Sriel, to transfer intelligence information held by the Unit to the computing giant’s servers. According to an internal Microsoft document, which was leaked by The Guardian, Sriel requested the transfer to Microsoft’s cloud of 70% of the unit’s data, including “secret and top secret” data.

The meeting allegedly led to the development of one of the world’s most invasive surveillance systems, which has been employed by Israel to monitor Palestinians in Gaza and the West Bank. According to documents cited by The Guardian, as of July this year, 11,500 terabytes of Israeli military data—equivalent to 862 billion documents or 195 million hours of audio—were stored on Microsoft Azure public cloud servers in the Netherlands. A smaller portion of the data was stored in Ireland and Israel. Read more of this post
