Crypto Hacks Affected More Than $1.17 Billion in Q3 2026

Crypto-related hacks and exploits affected approximately $1.174 billion in assets from July 1 through Sept. 30, with major incidents spanning exchanges, blockchain infrastructure, lending protocols and hardware wallets.

The figure measures the gross value of assets affected when each incident occurred. No definitive net-loss total was established.

Bitget’s Sept. 24 breach was initially estimated at $351.6 million after unauthorized transfers were detected at 2:31 p.m. ET (18:31 UTC). The affected amount was later revised to approximately $387.5 million after assets on Zcash and Tron were included.

The breach involved hot and warm wallets, while cold wallets remained secure and user account balances were unaffected. Bitget said, “User funds are safe.”

The Liquid Network incident involved approximately 4,000 Bitcoin (BTC) released through its peg-out mechanism on Sept. 6 at 11:53:10 a.m. ET (15:53:10 UTC). The Bitcoin was not backed by reserves, and approximately 3,400 BTC was returned on Sept. 7.

The Tectonic exploit on Aug. 30 involved approximately $120.4 million in borrowed assets after the attacker manipulated the price of TONIC by about 195 times. Approximately $9.19 million that left Cronos before the chain halted remained unrecovered.

A firmware flaw in Coldcard weakened seed generation and led to the draining of approximately 1,816 BTC from more than 5,200 addresses beginning July 30. The quarterly tally valued the incident at approximately $100 million, while a separate estimate put the value of the drained Bitcoin at about $116 million.

The AFX Bridge incident involved the transfer of 24.15 million USD Coin (USDC) on July 22 after validator infrastructure was compromised.

The incidents will continue to shape the recorded 2026 gross affected-value tally as additional events are documented through the end of the year.
