The Verge reports: On Wednesday night, someone drained funds from multiple cryptocurrency wallets connected to the decentralized finance platform BadgerDAO. According to the blockchain security and data analytics Peckshield, which is working with Badger to investigate the heist, the various tokens stolen in the attack are worth about $120 million.
While the investigation is still ongoing, members of the Badger team have told users that they believe the issue came from someone inserting a malicious script in the UI of their website. For any users who interacted with the site when the script was active, it would intercept Web3 transactions and insert a request to transfer the victim’s tokens to the
attacker’s chosen address. Because of the transparent nature of the transactions, we can see what happened once the attackers pounced. PeckShield points out one transfer that yanked 896 Bitcoin into the attacker’s coffers, worth more than $50 million.
