Crypto Hacks Jump 67% in August as Losses Fall to $136.3 Million
Key Takeaways
- •PeckShield counted 50 major crypto hacks in August, a 67% increase from July.
- •Estimated losses dropped to $136.3 million in August, down 49.5% from about $270 million in July.
- •The Tectonic.cro exploit drained about $74 million and represented more than half of August’s total losses.
- •Other notable August incidents included Moonwell, Term Labs, Coinsbuy, and TAC, each with losses of about $7.5 million to $8.7 million.
- •Cronos validators paused block production after the exploit, and the attacker moved about $6 million to Ethereum before the halt.
The crypto industry recorded 50 major hacking incidents in August, a 67% increase from July, according to PeckShield. Despite the sharp rise in attack frequency, estimated losses fell 49.5% month over month to $136.3 million from about $270 million.
The figures point to a notable shift in the crypto security landscape. August saw more incidents, but fewer attacks produced the exceptionally large losses that drove July’s total, underscoring how monthly damage can be driven by a small number of outsized exploits rather than incident count alone.
Tectonic exploit accounts for more than half of August losses
The Tectonic.cro exploit accounted for more than half of August’s estimated losses. The Cronos-based decentralized finance lending protocol was attacked and drained of about $74 million.
The incident ranked as the fourth-largest crypto theft of 2026 so far. Other major August incidents included:
- Moonwell: about $8.7 million
- Term Labs: about $8.5 million
- Coinsbuy: about $7.9 million
- TAC: about $7.5 million
Excluding the Tectonic incident, the other 49 reported attacks generated roughly $62.3 million in combined losses.
Cronos response limited fund movement
The Tectonic attack triggered a rapid response from the Cronos network. Validators paused block production after detecting the exploit.
The attacker moved about $6 million to Ethereum before the network halted. Most identified funds remained on Cronos at that point, limiting the amount that could move across networks.
Cronos later restored the network to a state preceding the exploit. Meanwhile, investigators continued tracking the stolen assets and potential cross-chain movements.
Security risks remain elevated
August’s lower loss figure does not indicate that crypto security risks have disappeared. The data shows how heavily monthly losses can depend on a small number of major exploits.
The increase to 50 incidents also points to persistent threats across decentralized finance, smart contracts, and blockchain infrastructure, areas where rapid detection and coordinated response can materially affect how far an attack spreads. For crypto users and businesses, stronger monitoring and incident response remain critical as attackers continue to target digital assets.
