Quick answer

Cronos blockchain temporarily suspended operations after a $74M attack on DeFi platform Tectonic: the attacker manipulated the TONIC token price, borrowed assets, and withdrew about $6M in Ethereum.

The Cronos blockchain, affiliated with Crypto.com, temporarily suspended operations following a major attack on the decentralized lending platform Tectonic. The incident led to the manipulation of the TONIC token price, which was artificially inflated 100-fold within just 20 minutes.

Using the inflated TONIC price as collateral, the attacker successfully borrowed assets worth $74 million. However, only about $6 million in Ethereum was withdrawn, as the remaining funds remained locked within the Cronos network. According to security firm PeckShield, most assets were never extracted from the system.

Upon detecting the breach, Cronos immediately froze all transactions and restored the blockchain to its pre-attack state. The team emphasized that these actions were taken under an emergency protocol to protect users.

By the time operations resumed, Tectonic’s total locked value had plummeted from $122 million to under $3 million, indicating a significant liquidity drain. Tectonic confirmed an ongoing investigation and urged users to refrain from interacting with the platform until a final report is published.
