Crypto security incidents caused approximately $1.26 billion in losses during the third quarter of 2026, marking a 53.9% increase from $819.4 million in the previous quarter. The sharp rise in financial damage highlights escalating risks across the digital asset ecosystem despite ongoing security efforts. A total of 247 security incidents were recorded in Q3, representing a 12.8% quarter-over-quarter increase in attack frequency. The disproportionate growth in losses compared to incident volume suggests attackers are targeting higher-value protocols and executing more sophisticated exploits.
