Crypto security incidents · week 44, 2026 (Oct 26 to Nov 1)
This week (Oct 26 to Nov 1), 11 crypto security incidents were publicly reported, with about $6.37B lost: 269 times last week (8 incidents, $23.6M). The largest was Binance CEX on Oct 29, about $6.36B, caused by a hijacked website frontend. 5 were phishing, a fake website or a rugpull (about $6.36B in total). These happen at the moment of payment, so checking the payee address and the website before paying can stop some of them.
