Odaily Planet Daily reports that Yearn Finance has released a detailed post-incident report on last week's yETH vulnerability attack, pointing out a three-phase numerical error in its legacy stableswap liquidity pool. This error allowed attackers to "mint" LP tokens indefinitely and steal approximately $9 million in assets from the liquidity pool. Yearn has confirmed that, with the assistance of the Plume and Dinero teams, they have successfully recovered 857.49 pxETH, approximately one-quarter of the stolen assets. The team plans to distribute the recovered funds proportionally to yETH depositors. The decentralized finance protocol stated that the vulnerability occurred in block 23,914,086 on November 30, 2025. The attacker, through a complex sequence of operations, forced the internal resolver of the liquidity pool into a divergent state, ultimately triggering an arithmetic underflow. The attack targeted a custom stableswap pool aggregating multiple liquidity staking tokens (LSTs), as well as a yETH/WETH Curve pool. Yearn emphasized that its v2 and v3 vaults and other products were unaffected. To address these issues, Yearn released a fix plan that includes implementing explicit domain checks on the resolver, replacing unsafe arithmetic in critical sections with checked arithmetic, and disabling bootstrapping logic after the pool comes online.

According to SlowMist, the decentralized finance protocol yearn suffered a hacker attack on December 1st, resulting in a loss of approximately $9 million. The SlowMist security team analyzed the incident and confirmed the root cause as follows: The vulnerability originates from the `_calc_supply` function logic used to calculate the supply in the Yearn yETH Weighted Stableswap Pool contract. Due to insecure mathematical operations, this function allows for overflow and rounding errors during calculation, leading to a significant deviation in the calculation of the product of the new supply and the virtual balance. Attackers can exploit this flaw to manipulate liquidity to a specific value and over-mint liquidity pool (LP) tokens, thereby illegally profiting. It is recommended to strengthen boundary scenario testing and adopt a securely verified arithmetic operation mechanism to prevent high-risk vulnerabilities such as overflows in similar protocols. Previously, Yearn issued a statement saying that its yETH stable pool was attacked at 21:11 UTC on November 30. The attacker minted a large amount of yETH through a custom contract, resulting in the loss of approximately $8 million in assets in the pool. Another $900,000 in losses came from the yETH-WETH pool on Curve.

Odaily Planet Daily reports that Yearn issued a statement saying its yETH stablecoin pool was attacked at 21:11 UTC on November 30th. The attacker minted a large amount of yETH through a custom contract, resulting in a loss of approximately $8 million in assets within the pool. An additional $900,000 in losses came from the yETH-WETH pool on Curve. Yearn stated that the affected code is unrelated to other products, and V2/V3 Vaults were unaffected. The company also noted that the complexity of the incident is similar to the previous attack on Balancer. The team has joined forces with SEAL911 and the auditing firm ChainSecurity to conduct an investigation.

Odaily Planet Daily reports that Yearn Finance's yETH product appears to have been attacked today. Attackers exploited a vulnerability that allowed for the "unlimited minting" of yETH, rapidly draining the entire yETH pool in a single transaction. According to on-chain data, approximately 1,000 ETH (about $3 million) were subsequently transferred to Tornado Cash. The attack appears to have been carried out through multiple newly deployed contracts, some of which self-destructed immediately after the transaction. The extent to which the approximately $11 million in the original yETH pool was affected remains uncertain. The incident was initially discovered by X user Togbe while monitoring large transactions. Yearn officials stated they are investigating the matter and emphasized that their V2 and V3 Vaults were not affected. The situation is still developing.

According to Odaily Planet Daily, Schlag, a member of the yearn community, posted on the X platform that Stream's losses were due to high leverage, directional trading, and a lack of transparency in fund usage. He emphasized that DeFi projects should focus on standardization and information disclosure, and that vault operations should not only pursue returns but also strengthen risk management. In response, Aave founder Stani.eth retweeted and commented that the immutable oracle price feed and interest rate curve mechanisms mentioned in the article are "highly alarming," and that this combination of designs could potentially be disastrous for lending protocols. He pointed out that some asset managers, in pursuit of competitive advantage, have taken on excessive risk, further amplifying the industry's hidden dangers. Stani stated that building a secure and robust DeFi system is inherently challenging, currently not only because investors lack sufficient due diligence, but also because of insufficient risk awareness at the protocol integration level. He called on the industry to work together to improve transparency and prudent management, and jointly build a safer and more sustainable decentralized finance ecosystem.
