Ankr ankrFLOW contract was attacked, and the Flow Foundation will make up the funds

Flow blockchain officially announced that at approximately 06:18 UTC today, there was a vulnerability in Ankr's ankrFLOW liquid staking contract, allowing attackers to create about 8.6 million uncollateralized ankrFLOW. This is not a vulnerability of the Flow EVM or the Flow protocol and does not affect the Flow token economics.

The attackers subsequently used ankrFLOW as collateral to deplete approximately 15.5 million WFLOW reserves on the MORE Markets lending protocol, valued at about $410,000, and made a profit of about $246,000 after slippage. Some reports incorrectly stated that the impact was around $9.3 million. Ankr and MORE Markets have suspended the related contracts, and some exchanges have proactively suspended FLOW deposits.

The Flow Foundation will work with Ankr to replenish the stolen WFLOW reserves and rebalance the liquidity pool. The Flow network is operating normally, and ankrFLOW staking and MORE Markets lending will be suspended until Ankr deploys a fix upgrade. User funds are safe, and no action is required.
