Golden Finance reported that the native token of the Holograph protocol, HLG, fell by more than 60% after a malicious attacker exploited a vulnerability to mint 1 billion HLG. Data shows that this incident caused the market price of HLG to fall sharply. The attacker successfully minted an additional 1 billion HLG tokens by exploiting a vulnerability in the Holograph operation contract. The Holograph team has fixed the vulnerability and is working with several exchanges to block malicious accounts. According to on-chain data, the wallet acc01ade.eth involved in the vulnerability also shows on its Github page that it is one of the contributors to the Holograph project. At present, the team is conducting further investigations and contacting law enforcement agencies. The Holograph protocol aims to achieve a unified contract address on all Ethereum Virtual Machine (EVM) blockchains to ensure the consistency, interoperability and secure transfer of cross-chain assets of tokenized operations.
