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 highlight a notable shift in the crypto security landscape. More incidents occurred in August, but fewer attacks produced the exceptionally large losses that drove July’s total.
Tectonic Exploit Dominates August Losses
The Tectonic.cro exploit accounted for more than half of August’s estimated losses. The Cronos-based decentralized finance lending protocol suffered an attack that drained 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
If the Tectonic incident is excluded, the other 49 reported attacks generated roughly $62.3 million in combined losses.
Cronos Response Limited Fund Movement
The Tectonic attack also 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. Mean while, investigators continued tracking the stolen assets and potential cross-chain movements.
Security Risks Remain Elevated
August’s lower loss figure does not signal that crypto security risks have disappeared. Instead, the data shows how heavily monthly losses can depend on a handful of major exploits.
The increase to 50 incidents also points to persistent threats across decentralized finance, smart contracts and blockchain infrastructure. For crypto users and businesses, stronger monitoring and rapid incident response remain critical as attackers continue to target digital assets.
