This year, hackers were able to steal more than $600 million from Axie Infinity’s Ronin bridge by taking advantage of a validator node flaw.
The North Korean group Lazarus went after people who worked for the company that made Axie Infinity, Sky Mavis. They contacted people on LinkedIn on behalf of a fake company, and when people fell for it, they set up multiple fake job interviews and then a “extremely generous” fake pay package.
The scam ended when a senior engineer clicked on a PDF that was supposed to be the official offer. When the engineer’s computer and four of the nine nodes used to verify financial transactions on Sky Mavis’ Ronin blockchain were taken over by hackers, the scam was over.
