Q3 Crypto Hacks Reach $1.2B

Cryptocurrency hacks soared to $1.18 billion across 107 recorded incidents in the third quarter of 2026, according to security company Hacken. The four largest incidents included the $387 million Bitget hack, the $320 million Liquid Network exploit, the $120 million Tectonic exploit, and the Coldcard firmware vulnerability.

Causes of the Hacks

About 77% (about $906 million) of the quarter’s total losses were attributed to compromised suppliers or developer tools, publicly disclosed fixes that had not been deployed, or other components outside security reviews.

#

Industry Response

Hacken urged industry participants to strengthen the cybersecurity of third-party suppliers, developer tools and other external infrastructure that may fall outside security audits. The company also recommended that protocols expand security audits to include oracles, bridgers, custody systems, signing authorities and other privileged components.
