Incident Overview
On the main website, there was false information concerning collaboration with Lloyds Bank. The YFDash project used the same token ticker as the legitimate YfDFI Finance to confuse the audience. The project team promised that it would be listed on Uniswap immediately following the token sale event. The token contract deployer created 20K tokens, of which 4K were transferred to an EOA wallet and 2318 were exchanged for 103 ETH:

The project's website is no longer operational, and its Twitter account has been deactivated.

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.
What Auditors Should Check
If you're auditing a protocol with similar architecture to YFDash, these are the critical security checks that could have prevented this incident (December 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
