Incident Overview
In October, well over 3,700 Bitcoins went missing. Unlike the previous hack, the reason for this loss seems to come from having entrusted a malicious individual – Moolah’s CEO Alex Green is accused of having stolen almost $1,500,000 from Mintpal clients.

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 MintPal, these are the critical security checks that could have prevented this incident (October 2014).
- Verify all logic paths related to Access Control are guarded by proper access controls and input validation - see the Access Control 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
