🔍Crypto exchange Kraken has recovered nearly $3 million in digital assets that went missing due to a bug bounty exploit. The saga began when blockchain security firm CertiK, initially referred to as a "security researcher", discovered a vulnerability and withdrew the funds. Kraken accused CertiK of extortion, while CertiK claimed they were testing the limits of Kraken's protection and risk controls. After a public back-and-forth, the funds were returned, minus transaction fees. CertiK insists no user funds were at risk as the exploited funds were "minted out of air".
