Yearn Finance reported a security breach on November 30 that resulted in approximately $9 million in losses. The attack targeted a vulnerability in a legacy yETH stableswap pool, allowing unauthorized token minting. Blockchain security firm PeckShield tracked roughly $3 million of the stolen funds to Tornado Cash, while the remaining $6 million remains in the exploiter's wallet.

Yearn Finance's yETH vault suffered a security breach that resulted in approximately $3 million worth of ETH being stolen. The attacker exploited a smart contract vulnerability to mint excessive tokens and drain the liquidity pool. Other Yearn vaults remained unaffected, with V2 and V3 operations continuing normally.

Yearn Finance's yETH staking token was exploited on December 1, resulting in approximately $3 million in ETH losses. The attacker minted tokens without authorization and transferred 1,000 ETH to Tornado Cash. Yearn confirmed its V2 and V3 Vaults remain secure and unaffected by the breach.

Democratic staff of the House Judiciary Committee released a 68-page report on November 24, 2025, alleging President Trump and family members built a cryptocurrency portfolio valued between $2.9 billion and $11.6 billion at 2025 peak prices. The document claims White House pardons and regulatory decisions directly benefited entities that invested in Trump-linked crypto projects. The family controls World Liberty Financial, which raised $550 million, and launched the $TRUMP memecoin that reached an $18 billion market cap.

A House Judiciary Committee staff report alleges President Donald Trump's cryptocurrency portfolio may be valued as high as $11.6 billion, with over $800 million in crypto asset sales income recorded in the first half of 2025.

Major layer-1 blockchain networks are incorporating post-quantum cryptography into their technical roadmaps as a long-term security priority. The shift follows NIST's standardization of quantum-resistant algorithms between 2022 and 2024. Teams are addressing potential vulnerabilities in elliptic-curve signature schemes before quantum computers reach cryptanalytic capability.
