Secret Network Bridge Hacked for $4.7M Using an 'Infinite Mint' Bug — Here's What Went Wrong
51d ago · 1 source
An attacker exploited a vulnerability in Secret Network's cross-chain bridge, minting unlimited tokens and draining approximately $4.7 million in funds. The exploit leveraged an 'infinite mint' bug, a type of vulnerability that allows an attacker to create tokens without limit, effectively stealing value from the protocol and its users.
WHY IT MATTERS
Think of a cross-chain bridge like a currency exchange booth at an airport — you hand over dollars on one side and receive euros on the other. Now imagine someone found a glitch in the exchange booth's computer that let them print unlimited euros without handing over any dollars. That's essentially what an 'infinite mint' bug does. The attacker created tokens out of thin air and traded them for real money, stealing $4.7 million. This matters because bridges are a critical part of how different blockchains communicate, and when they get hacked, real people lose real money. It's a reminder that in crypto, the technology connecting blockchains is often the weakest link in the chain.
