Leaks, data breaches, and ransom notes: The worst hacks of 2026 so far

TechCrunch's 2026 roundup covers SSA data exposure, Iranian water-utility attacks, Klue breach hitting ~200 firms, and Meta AI chatbot account hijacks.

TechCrunch's mid-year roundup highlights a whistleblower claim that DOGE uploaded a live Social Security database copy to an unsecured third-party server, which House Democrats called potentially the largest US breach in history. CISA reported Iranian hackers targeted over 100 US water providers over the summer, while Russian-linked attacks hit Polish, Swedish, and Norwegian energy and water infrastructure. Market research firm Klue was breached via a stale 2022 pilot credential, exposing cloud keys of ~200 customers including Jamf, HackerOne, and LastPass to extortion gang Icarus.
