Unit 8200 is the unit of the Israel Defense Forces (IDF) responsible for signals intelligence. With an estimated 5000 active duty soldiers, it is the largest military intelligence unit in the IDF. It handles open-source intelligence, threat assessment, cryptanalysis, and cyberwarfare. In terms of technical expertise, Unit 8200 has been described by experts as on par with the U.S. National Security Agency (NSA). Unit 8200 is believed to have played a key role in dramatic operations ranging from the Stuxnet virus that crippled Iran’s nuclear centrifuges in the 2000s to the September 2024 attacks on Hezbollah via compromised pagers and other communications devices rigged with explosives. Alumni of Unit 8200 have also played a key role in the Israeli software and startup sectors: they have founded hundreds of cybersecurity companies, including Check Point, Palo Alto Networks, CyberArk, Wiz, and the controversial NSO Group, as well as successful consumer tech startups like Viber and Waze. Since the renewed outbreak of war in the Middle East caused by the October 2023 attacks on Israel by Hamas, Unit 8200 has been a key organization applying new artificial intelligence technologies to problems in warfare.
