Secret bridge exploited for $4.67 million a week before anyone notices

The bridge between the Cosmos-based Secret network and Axelar network was exploited via an infinite mint bug that went unnoticed for a week. An attacker exploited a smart contract in order to mint a large quantity of wrapped Axelar tokens on the Secret network, which they then redeeemed for around $4.67 million.

The exploit, which occurred on June 10, went unnoticed until June 17, when a transaction failed with a message suggesting that more tokens had been bridged out of the Secret network than had been bridged in.

Secret has warned, "If you hold Axelar-bridged saXXX tokens on Secret, please be aware their backing was affected and your funds may be lost."
