Yearn Finance reported that a legacy yETH product was hit by an exploit that 
allowed an attacker to mint a massive amount of fake tokens and swap them for 
real assets. Related Reading: Bitcoin Miners Face A Harsh December: Rising BTC 
Difficulty, Falling Hashprice According to on-chain alerts and protocol 
statements, the attacker created a near-infinite supply of yETH in a single 
transaction, then used those tokens to pull ETH and liquid-staking derivatives 
from liquidity pools. The incident was first flagged on November 30, 2025, and 
the total impact has been reported at roughly $9 million. #PeckShieldAlert 
Yearn Finance @yearnfi suffered an attack resulting in a total loss of ~$9M. 
The exploit involved minting a near-infinite number of yETH tokens, depleting 
the pool in a single transaction. ~1K $ETH (worth ~$3M) was sent to

PeckShieldAlert (@PeckShieldAlert) December 1, 2025 How The Exploit Worked 
Based on reports, the attacker took advantage of a flaw in the yETH minting 
logic and produced tokens on the order of 235 trillion in one go. Those 
worthless tokens were then swapped for real assets from Balancer and Curve 
pools tied to the product, emptying liquidity in minutes. Chain monitors and 
security researchers showed the mint and subsequent swaps unfolding very 
quickly on the blockchain. At 21:11 UTC on Nov 30, an incident occurred 
involving the yETH stableswap pool that resulted in the minting of a large 
amount of yETH. The contract impacted is a custom version of popular 
stableswap code, unrelated to other Yearn products. Yearn V2/V3 vaults are not 
at risk. — yearn (@yearnfi) December 1, 2025 What Assets Were Taken Reports 
have disclosed that roughly $8 million was pulled from the main yETH stable- 
swap pool, while about $0.9 million was taken from a yETH–WETH pool. In 
addition, roughly 1,000 ETH—valued at about $3 million at the time of 
movement—was sent to Tornado Cash in attempts to obscure the trail. The 
attacker converted fake yETH into a mix of ETH and liquid staking tokens 
before attempting to launder funds. Impact On Yearn’s Core Products According 
to Yearn officials and follow-up coverage, the breach was limited to an older, 
legacy implementation of the yETH product and did not affect Yearn’s main V2 
and V3 vaults. Deposits into the affected pool were isolated while the team 
and outside experts began an investigation. This isolation is said to have 
kept the bulk of user funds in active vaults from being touched. Market 
Reaction And Wider Concerns Crypto markets saw selling pressure as the news 
spread, with traders weighing the risk that comes from combining liquid 
staking tokens with custom swap code. Related Reading: Bitcoin Sentiment 
Sparks CZ Comment: Sell Greed, Buy Fear Yearn Finance said it is working with 
outside security teams to run a post-mortem and to patch the vulnerability. 
Based on reports, teams named in coverage include external auditors and 
blockchain investigators who are tracking the stolen funds and advising on 
recovery options. The protocol’s notice warned users about the affected legacy 
product and urged caution while the review continues. Featured image from
