Aethir Contains Bridge Hack While Losses Stay Below $90K

Aethir said it remains fully operational after containing an attack on its ATH bridge contracts. 

The company said the exploit did not affect the main ATH supply on Ethereum, while user losses stayed below $90,000.

Aethir said it detected a malicious attack targeting ATH bridge contracts that connect Ethereum with other chains. The company said it disconnected all affected contracts soon after finding the issue and stopped further damage.

The team added that the ETH-ARB bridge on Squid was not affected during the incident. It also said the main ATH supply on Ethereum remains intact, which helped prevent wider disruption across the network.

Aethir said it will share a full compensation plan next week. The company also said it is working with authorities and exchange partners to trace the attacker and block related funds.

“A full attacker wallet list will be posted in Discord as we monitor the funds,” Aethir said, in its update.

It added that a detailed memo will explain what happened, which users were affected, and how compensation will work.

Aethir credited several exchanges for acting quickly after the exploit. The company named Binance, Upbit, Bithumb, and HTX among the platforms that blacklisted identified wallets tied to the incident.

The project also thanked ZeroShadow for helping with analysis during the response. Aethir said that early action from partners helped limit the scope of the losses and support the ongoing investigation.

PeckShield had flagged the exploit a day earlier and initially estimated losses at about $400,000. The blockchain security firm also said the attacker moved funds from BNB Chain to Tron through several addresses.

That early estimate differed from Aethir’s latest figure of under $90,000 in user losses. The gap places more attention on fund tracing and the final accounting of the incident.

Crypto attacks continue to pressure the market

The Aethir case comes as crypto security breaches keep hitting the market. PeckShield recently said losses from 20 security incidents reached about $52 million in March, nearly double the February total.

The firm also pointed to a growing pattern where one exploit can spread stress across linked DeFi platforms. Those events can weaken liquidity, create bad debt, and strain lending markets beyond the first target.

PeckShield cited ResolvLabs and Venus Protocol as recent examples of wider fallout after exploits. It also noted targeted attacks on individuals, including a multimillion-dollar theft tied to social engineering on Kraken. The trend has carried into April as other platforms deal with new attacks.
