Polymarket: Private key rotation has been completed, and the next step is to migrate the private keys to a key management service.

According to Huoxun Finance, a representative from the prediction market platform Polymarket stated that the security incident was caused by the leakage of an internal recharge configuration private key that had been in use for six years, resulting in some funds flowing to related addresses. The team has now completed private key rotation, reclaimed all production environment access, and will subsequently migrate all private keys to a Key Management Service (KMS), abandoning the traditional storage method. The platform and UMA contracts were not attacked, user funds are safe, and operations are unaffected.
