And that's what the Ronin Bridge did.
It moved value from the Ronin blockchain to Ethereum.
So enormous amounts of cryptocurrency were constantly sitting inside the Ronin Bridge.
And it wasn't just a choke point for North Korean hackers.
That made this bridge a massive honeypot.
Those bridges are often less secure than the blockchains they connect.
And North Korea realized this before most of the security community.
North Korea exposed just how vulnerable these bridges were, but they're not without security.
The Ronin Bridge required our old friend, multi-sig validation, a quorum of approvals from designated signers.
But in this case, the quorum was pretty small, just five signatures out of nine.
That meant that if hackers could compromise only five validators, they could drain the bridge.
And that's exactly what happened.
They had to have a quorum to approve this.
But a majority of those were actually just controlled directly by Axie.
So if you were able to penetrate Axie's machine, you got access to like five or six of these signatures.
And how did they get there?
They went after the developer.
They used social engineering and our human weaknesses.
It wasn't technical brilliance.
It was social engineering mastery.
