Crypto Hackers Drain $768M In September, Bitget Drives Half The Losses

Hackers stole about $768.4 million in cryptocurrency during September, making it the costliest month for crypto security incidents in 2026.

Key Points:

• CertiK counted 97 incidents with estimated losses of $768.4 million, while PeckShield tracked 55 incidents totaling $766.5 million.
• Bitget and Liquid Network accounted for roughly 92% of the losses in PeckShield’s September tally.
• CertiK’s year-to-date data showed 656 security incidents and about $2.68 billion in losses through September.

Bitget Crypto Losses

September produced the highest monthly crypto loss total of 2026, although the firms recorded different incident counts.

Bitget was the largest single case, with its loss estimate rising from an initial $351.6 million to $387.5 million after investigators confirmed how much cryptocurrency reached attacker-controlled addresses. The exchange’s breach accounted for roughly half of CertiK’s monthly total.

Liquid Network’s Sep. 6 exploit involved a different failure, as a verification flaw allowed an attacker to create around 4,000 Liquid Bitcoin (L-BTC) without corresponding Bitcoin (BTC) backing. The attacker then used the network’s withdrawal process to extract close to 4,000 BTC, cutting its Bitcoin reserve from roughly 4,205 BTC to 197 BTC.
