Thief lays trap to claim 3 million ARB tokens in upcoming airdrop
The crypto criminal sent ether to around 2,400 wallets in order to approve a contract that allows recipients to claim the airdrop, which is set for Thursday. Normally this wouldn’t be a problem, but this person also appears to have access to the wallets' private keys. The approved contract will automatically claim the airdrop on behalf of the thief, bypassing any bots that might be set up to sweep funds that land in the wallets.
Word of the scheme was first brought to light by Arkham Intelligence and a post on GitHub. The ARB token will control the governance of the Arbitrum One and Nova networks through a DAO. Since the bad actor knows the private keys for the wallets, wallet owners can’t necessarily block them. What they can do is revoke the contract that has been set up — but even then they would still need to manually claim the airdrop before the hacker does. In a world often rife with exploits, this attempt to hijack an airdrop is unique. If successful, it means the thief would end up claiming 0.26% of the user airdrop by siphoning them from wallets.
