Secret Network bridge exploited in $4.7 million ‘infinite mint’ attack
Secret Network’s bridge was exploited in an attack that went undetected for about a week. The attacker moved the funds into Ethereum and later to exchanges.
What happened?
Secret Network’s bridge was exploited in an attack that went undetected for about a week. The attacker moved the funds into Ethereum and later to exchanges.
Why it matters
The incident matters because bridge exploits remain one of the most damaging attack vectors in crypto, affecting users, protocols, and liquidity across multiple chains. When bridged assets are compromised, the impact can extend beyond the targeted network and create broader security concerns for the ecosystem.
Secret Network’s bridge was exploited in a $4.7 million attack tied to an “infinite mint” bug, with the activity going unnoticed for about a week. According to the source, the attacker then moved the stolen assets into Ethereum and later sent them to exchanges.
The incident matters because bridge exploits remain one of the most damaging attack vectors in crypto, affecting users, protocols, and liquidity across multiple chains. When bridged assets are compromised, the impact can extend beyond the targeted network and create broader security concerns for the ecosystem.
In this case, the delay in detection gave the attacker time to move the funds through other networks and into exchange venues, which can make recovery more difficult. The report highlights how quickly cross-chain vulnerabilities can ripple through connected platforms once an exploit is underway.
Secret Network has not been described in the source as the only protocol facing this kind of risk, but the case adds to a long list of bridge-related incidents that have tested confidence in cross-chain infrastructure. It also underscores the operational challenge of monitoring complex systems for subtle bugs that can remain hidden after deployment.
