Nimiq Hit with $50k Loss as Exploit Exposes Smart Contract Vulnerability

Nimiq's blockchain protocol has suffered a significant loss due to an exploit in its ERC20PermitHTLCHandler smart contract. The incident resulted in a loss of approximately $50,463.

The vulnerability was identified by @SlowMist_Team on CryptoTwitter and highlights the importance of robust security measures in smart contract development.

The exploit occurred when an attacker manipulated the contract's execution flow, allowing them to siphon funds directly from a victim's balance. The ERC20PermitHTLCHandler failed to conduct necessary parameter checks, which enabled the attack.
