In October 2023, anti-Israel hackers published classified data, causing severe damage to Israel's cybersecurity infrastructure.
Anti-Israel hackers have published extensive amounts of classified data targeting military, defense contractors, hospitals, and government ministries, overwhelming Israel's cybersecurity infrastructure. The leaked data, which began on October 7, 2023, appeared on Telegram, complicating Israeli authorities' efforts to remove it. The true extent of the damage is not yet known, but the leaks are believed to be the most severe in Israel's history. Israel has attempted to mitigate the damage through legal steps and direct talks with tech giants like Google, Amazon, and Meta, while the founder of Telegram, Pavel Durov, was detained by French authorities on an arrest warrant issued over the lack of moderation on the platform.
