A recent incident report from the Shiroi project alleges that Marinade Finance has been exploited by malicious validators for over a year. The report claims that over 37,000 SOL in rewards, valued at more than $6.5 million, were siphoned from the protocol. This exploitation is said to stem from Marinade's Stake Auction Marketplace (SAM), which allows validators to bid for stake. Shiroi found that some validators received stake without adequately paying for it, averaging around 28% of the total delegated stake, which undermines the yields advertised to stakers. The report also identifies the top 10 exploitative validators, some of which remain active and appear to have backing from significant entities like Jito and the Solana Foundation. Although Marinade has attempted to address the concerns, including implementing measures against specific attacks, critics underscore the need for a more decisive response. They argue that the findings affirm longstanding concerns regarding validator behavior within the system, highlighting a critical moment for accountability in Marinade Finance.
