Incident Overview

The project was holding a presale in 2 ways:

1. Funds were transferred to the contract deployer's address:

https://bloxy.info/ru/txs/transfers_to/0x6fb20901…7ac728?currency_id=1

2. Funds were transferred to the contract deployer's address through a separate contract which was used for the presale:

https://etherscan.io/address/0x6fb20901…7ac728#internaltx

The stolen ETH was transferred to the external address, marked as Phishing:

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 rugpull and Solidity and EVM internals
Capital Required Seed capital to cover gas and initial position setup
On-Chain Access Ability to interact with ethereum smart contracts and deploy a custom exploit contract
Protocol Analysis Identification of the exploitable vulnerability in Santa DAO's contract logic - root cause: other
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? Hard to catch — private key / OpSec failures are outside smart contract audit scope
Audited by Audit Report 1 — still lost $204K. Prior audits don't guarantee safety, especially after post-audit code changes.

If you're auditing a protocol with similar architecture to Santa DAO, these are the critical security checks that could have prevented this incident (October 2020).

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