On December 2, 2021, Badger DAO suffered a $120M hack when an attacker used a compromised Cloudflare API key to inject malicious code into the frontend. Users unknowingly approved token transfers via spoofed UI, allowing the attacker to drain approximately 2,100 BTC and 151 ETH from ~200 accounts.

The decentralized organization Badger DAO was attacked by hackers, and user assets were transferred without authorization. According to the developer's initial inventory of damaged assets, 136,000 bcvxCRV, 64,000 bveCVX, 38 ibBTC/sBTC, 13 bibBTC/sBTC, and 19 DIGG have been lost in this incident.
