Ongoing since 10:46 AM UTC, affecting Solana Validator.
Between 26 and 27 October, Blockdaemon identified that operator keys for a small set of our oldest running Solana validators were compromised. The attacker was able to change the withdrawal authority on the impacted validators and move a limited amount of operational assets from their operational accounts. Your delegated SOL is safe. There is no indication of loss or risk to staked principal. Delegated SOL remains in each delegator’s own stake account and was not moved. Reward impact: Because we cannot fund the voting accounts on the compromised validators, they will not earn rewards starting with epoch 1070. Recommended action: The impacted validators must be replaced. A new validator is being prepared, and we will post its details here as soon as it is available. We are working directly with affected customers to move stakes to newly created validators quickly and minimise gaps in rewards. If you need help deactivating, withdrawing or re-delegating, please contact Blockdaemon support - [email protected] Full details and live updates are published here: https://www.blockdaemon.com/incident-reports/operational-impact-on-solana-validators
