Incident Overview

Boris Wagner's Discord was compromised, which the hacker took advantage of by posting a phishing link with airdrop through his account.

The Bored Ape Yacht Club is a collection of 10000 unique Bored Ape NFTsβ€” unique digital collectibles living on the Ethereum blockchain.

After gaining access to the employee’s account, scammers shared a phishing link from Vagner’s Discord account into the official BAYC, MAYC and Otherside groups. The community, without suspecting anything suspicious, without hesitation followed the link and clicking on the "get airdrop" button signed a transaction to give all their funds to the scammers.

What the Attacker Needed to Succeed

Understanding the prerequisites for this type of attack helps auditors identify protocols that are most at risk and helps developers build better defenses.

Technical Knowledge Deep understanding of phishing and Solidity and EVM internals
Capital Required Seed capital to cover gas and initial position setup
On-Chain Access Ability to interact with smart contracts and deploy a custom exploit contract
Protocol Analysis Identification of the exploitable vulnerability in BAYC & OtherSide's contract logic - root cause: nft
Execution Speed Precise transaction ordering and timing to exploit the vulnerability within a single atomic block
Obfuscation Plan A strategy to launder and move stolen funds - typically through mixers, cross-chain bridges, or decentralized DEX swaps to resist tracing

What Auditors Should Check

Could this have been caught in audit? Likely β€” with a thorough Phishing audit checklist and test coverage

If you're auditing a protocol with similar architecture to BAYC & OtherSide, these are the critical security checks that could have prevented this incident (June 2022).

  • Verify all logic paths related to Phishing are guarded by proper access controls and input validation - see the Phishing Attacks attack class for patterns
  • Review privileged functions (owner, admin, governance) for potential abuse vectors - centralization risks should be documented and bounded with timelocks or multi-sigs
