On October 7, BNB Chain announced suspending operations due to irregular activity, and a potential exploit.
Due to irregular activity we're temporarily pausing BSC. We apologize for the inconvenience and will provide further updates here.— BNB Chain (@BNBCHAIN) October 6, 2022
Thank you for your patience and understanding.
Later, the team confirmed they had detected an exploit on a cross-chain bridge BSC Token Hub. As a result, extra BNB coins were created. The Binance team announced that customer funds remained safe.
According to initial estimates, hackers were able to withdraw funds worth between $100 M- $110 M. However, due to the community response, $7 M has already been frozen. The validators confirmed their status and the community infrastructure updates after the issue was contained. Currently, the BNB chain is back to normal.
