Hackers Steal $7.5M in Ether from Arbitrum-based Jimbos Protocol

Arbitrum-based DeFi protocol Jimbos was hacked on May 28

Arbitrum-based DeFi protocol Jimbos was hacked on May 28, resulting in the loss of 4,000 Ether (ETH) worth approximately $7.5 million.

The attack was carried out by exploiting a vulnerability in the protocol’s liquidity conversion mechanism. The attacker was able to reverse swap orders for their own gain, resulting in the loss of funds.

Jimbos Protocol is a relatively new protocol, having only been launched in April 2023. The protocol aims to address liquidity and volatile token prices through a new testing approach.

However, the protocol’s mechanism was not adequately developed, leading to the logical vulnerability that was exploited in the attack.

The price of the underlying token, Jimbo (JIMBO), has plummeted by 40% as a result of the attack.

Hacking incidents in DeFi protocols are not a novel phenomenon. While reports indicate a significant decline in the number of attacks compared with previous years, the community continues to be exposed to numerous exploits.

Despite efforts to enhance security measures, the DeFi ecosystem grapples with the persistent challenge of safeguarding against potential vulnerabilities and unauthorized access.

The Jimbos Protocol hack is a reminder of the risks associated with DeFi protocols. Users should carefully evaluate the security of any DeFi protocol before investing funds.
