Incident Details

Web3 cybersecurity firm Hacken had a cybersecurity incident of their own when the private key belonging to a wallet with mint access for the project’s $HAI token was leaked. According to Hacken, the leak was attributable to “human error during architectural changes”. After a malicious party gained access to the key, they minted around 900 million $HAI on the Ethereum and BNB chains, almost doubling the total supply. The attacker only profited around $250,000, but they crashed the token price by around 97% in the process.

Total loss estimated at $250,000.
