Humanity Protocol has suffered a major security breach, resulting in the loss of over $31 million due to a leaked private key from a foundation member. The breach has led to the compromise of hundreds of wallets holding H tokens, with $9 million converted to ETH and $9.9 million remaining in H tokens. The incident has caused the H token price to plummet by over 90%, from 0.7 USDT to a low of 0.052 USDT, before recovering slightly to 0.1368301 USDT. Founder Terence Kwok confirmed the breach and advised users to avoid interacting with the project's cross-chain bridge and liquidity pools until further notice. The team is collaborating with security experts and exchange partners to address the situation. The attack, which involved the minting and selling of 100 million H tokens, highlights ongoing security challenges in the crypto industry, particularly concerning private key management.
