Plaintiff launches lawsuit against Dapper Labs for allegedly selling NFTs as unregistered securities
NBA Top Shot developer Dapper Labs has been sued for allegedly selling NFTs as unregistered securities. The allegations are based on the "personal knowledge" of lead plaintiff Jeeun Friel, according to a May 12 filing in New York Supreme Court. The filing claims "NBA Top Shot moments" are securities because their value increases with the success of the program. Plaintiffs claim that Dapper Labs should therefore register with the US SEC, which Dapper Labs failed to do. The company also allegedly used its control over NBA Top Shot to prevent investors from withdrawing their funds "for months on end," ensuring that funds remained on the platform to "prop up" its value. Dapper Labs has 30 days to respond to the subpoena. (CoinDesk)

PeckShield: DeFi Protocol bEarn Fi Hacked, Losing Nearly $11 Million
According to PeckShield's early warning, bEarn Fi, a cross-chain smart income and liquidity aggregator, was attacked and lost nearly 11 million US dollars. PeckShield reminds investors to invest cautiously.
According to the slow fog zone, xToken was attacked and lost nearly 25 million US dollars. The two modules that were hacked this time were the xBNTa contract and the xSNXa contract, which suffered from "counterfeit currency" attacks and oracle manipulation attacks respectively.
DeFi smart investment agreement Rari Capital released an analysis report and compensation plan after being attacked. Hackers stole about 2,600 ETH, or about $10 million, from the Rari Capital Ethereum fund pool, accounting for 60% of the fund pool. The DAO currently only holds 1% of the RGT supply, not enough to bail out platform users. In the proposal RIP-1 passed 5 months ago, it was proposed to reserve 2 million RGTs to expand the team size. At present, all protocol contributors choose to return these tokens to DAO to compensate users affected by the attack. As well as rewarding future contributors to the protocol. Next, users can propose compensation proposals to the DAO. Rari Capital will then check the security of the integrated protocol, conduct more audits, take measures to prevent deposits and withdrawals in the same block, and provide failsafe.
