Crypto security incidents cost $1.26 billion in the third quarter of 2026, according to a Cointelegraph report published Oct 1, 2026. The figure covers 247 separate incidents.
The biggest single loss was a $387.5 million hack of the exchange Bitget, which the report names as the main reason the quarterly total was so high. That one incident accounts for close to a third of the $1.26 billion.
September was the worst month of the quarter, with about $769 million in losses. The report does not say whether the Bitget hack happened in September.
The report gives no further detail on the hack. It does not say how the attack worked, which assets or accounts were affected, whether user funds were lost, or how Bitget responded.
For anyone already holding a perpetual position on Bitget, the report shows no direct effect. It says nothing about funding rates, trading fees, liquidity or whether Bitget's derivatives trading was interrupted, so based on what is known so far, the cost of holding a position has not changed.
