YFI +5.33% as Yearn Finance Recovers $2.4M Post-Hack

On DEC 2 2025, YFI rose by 5.33% within 24 hours to reach $3775, despite a 6.03% drop in the last seven days and a broader decline of 51.18% over the past year. This short-term rebound coincided with a partial recovery of assets following a major exploit of the Yearn Finance (YFI) protocol in late November.

Recovery Underway After $9M yETH Exploit

Yearn Finance announced the recovery of $2.4 million from the $9 million lost in a critical exploit that targeted the yETH stableswap pool on November 30. The exploit exploited a flaw in Yearn’s legacy contract, allowing attackers to mint a large amount of yETH and drain funds from two pools. Engineers from Yearn, along with security teams from SEAL 911 and ChainSecurity, responded rapidly to mitigate the damage and begin recovery efforts.

Through collaboration with Plume and Dinero, the team managed to retrieve 857.49 pxETH, valued at approximately $2.39 million, and pledged to return these funds to affected depositors without requiring legal or extended negotiation processes. The protocol emphasized that its V2 and V3 vaults—holding over $600 million in assets—were not impacted and remained secure.

Post-Mortem and Ongoing Security Efforts

Yearn Finance is currently conducting a full post-mortem of the incident, which will be released once audit partners finalize their review. In the meantime, affected users are encouraged to seek support via the project’s Discord channel. The team also noted that older contracts are being systematically reviewed to prevent similar vulnerabilities in the future.

The incident highlights the ongoing challenges DeFi projects face in maintaining security amid rapidly evolving infrastructure. Yearn’s prompt response and transparency have helped stabilize sentiment around the ecosystem, with the YFI token partially recovering after a sharp drop immediately following the exploit.

Yearn Finance continues to play a central role in the DeFi space, and its ability to manage this high-profile incident will be closely watched by both users and the broader crypto community.
