Crypto security incidents · October 2026
This month (Oct 1 to Oct 31), 21 crypto security incidents were publicly reported, with about $124.6M lost: 83% less than last month (36 incidents, $742.8M). The largest was Ledger (Supply Chain) on Oct 9, about $93.0M, caused by a hijacked website frontend. 2 were phishing, a fake website or a rugpull (about $97.2M in total). These happen at the moment of payment, so checking the payee address and the website before paying can stop some of them.
