The permissions change enabled the attacker to assume the Bridge role and mint collateral tokens directly from the lending pool. Using these illegitimately minted tokens, the attacker borrowed a large amount of assets, effectively draining the protocol’s liquidity.

CrediX announced that an investigation is ongoing and, as a precautionary measure, its website has been temporarily disabled to prevent any new user deposits.

The team assured users that all funds are safe and can still be accessed directly through smart contracts.

According to the statement, full recovery of user funds is expected within 24 to 48 hours.

All users funds will be recovered in full within 24-48 hours
