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. Separately, tens of thousands of Instagram accounts were hijacked by abusing Meta's AI chatbot to trigger password resets to attacker-controlled emails.

I Think the Military Commissary Freezers Were Hacked

Refrigeration failures at six-plus US military commissaries prompt speculation of a cyber attack on DeCA's remote monitoring systems; Pentagon acknowledges possible disruption.

The author documents near-simultaneous freezer and refrigeration failures at confirmed installations including Fort Huachuca, F.E. Warren AFB, Fort Irwin and Travis AFB on August 26-27, with freezers entering defrost mode that heated and spoiled food. DeCA's Remote Monitoring Control System controls defrost across roughly 182 locations, and an unverified comment attributed the Fort Huachuca failure to a network issue. Stars and Stripes and Military Times independently reported the multi-base failures, and the Pentagon acknowledged a 'possible refrigeration disruption,' though no evidence of hacking has been confirmed.

Trezor Says 347,000 Users Received Phishing Emails After Brevo Hack

Attackers abused Brevo's SAML SSO to access 138 accounts, sending phishing emails to 347,000 Trezor customers and exfiltrating contacts from 43 accounts.

Trezor said 347,000 of its customers received phishing emails with the subject line 'Critical Security Alert: STM32 Entropy Vulnerability' after the attacker compromised the Brevo marketing platform. Brevo said the intruder created an account, enabled SAML SSO, and used its own identity provider to access 138 accounts, exfiltrating contacts from 43 of them. Trezor reported 2,500 users clicked the malicious link before the site was taken offline 20 minutes after detection; potential fund losses are unknown. Swiss wallet maker BitBox and crypto tax calculator CoinTracking also appear affected, and Trezor separately disclosed a ShipMonk breach now affecting roughly 81,000 people.
