ChainCatcher reported that the private key of the deployer of the cryptocurrency liquidity staking platform StakeDAO (SDT) was leaked, resulting in 5.4 trillion vsdCRV being unauthorizedly issued by a hacker. More specifically, the deployer's private key on the Arbitrum (ARB) network was leaked, and the attacker reportedly swapped the unauthorizedly issued vcdCRV for approximately 43.7 ETH (about $90,000).
