According to ChainCatcher, the full-chain NFT protocol Holograph released an update on a recent security incident, saying that a former contractor exploited a vulnerability to mint an additional 1 billion HLG tokens on Mantle, causing the protocol to be temporarily locked.

The team is developing strategies to mitigate the impact of the vulnerability and working with security experts to prevent similar incidents from happening again. The attacker's exchange accounts on Bybit, Gate, KuCoin, Bitget, and Backpack have been frozen, and at least 200 million of the 1 billion additional HLGs have been frozen.

At the same time, relevant trading platforms have suspended all HLG deposits and withdrawals. Next, the official will conduct a third-party audit of the protocol and continue to promote the full-chain tokenization infrastructure and applications.
