TAC Releases August 22 Security Incident Review Report

TAC released its August 22 security incident review report and said the event involved a transfer rather than new issuance, with total supply unchanged and only TAC tokens affected. According to Foresight News, the recovery plan will restore staking balances through targeted state corrections instead of a block rollback, while the portion that entered the market and cannot be recovered on-chain, about 1.258 billion tokens, will be fully covered by the TAC Foundation treasury. The company said the disposal plan for assets still held by the attacker on BNB Chain remains under discussion and will be announced later. The cross-chain bridge between BNB Chain and TAC remains paused in both directions. TAC said the attacker used a vulnerability in the Cosmos EVM shared module to transfer 2,985,651,403.40 TAC from the staking pool, or about 28.6% of total supply, before bridging the tokens to BNB Chain and TON for phased selling. The attacker reportedly cashed out about 1.0058 million USDT in total, while about 1.662 billion TAC remained in the attacker’s BNB Chain address and about 65.1 million TAC were frozen on the TAC chain after the chain was paused.
