The cashio protocol on solana suffered an exploit resulting in the loss of around $50 million. The attacker was able to mint an infinite amount of tokens. The solana address for the attacker is 6D7fgzpPZXtDB6Zqg3xRwfbohzerbytB2U5pFchnVuzw. The attacker then used the solana worm hole bridge to swap to the ethereum blockchain where the funds still sit.
