Incident Overview
“In July 2013, BitFunder’s software was said to be hacked, enabling the theft of 6,000 bitcoin from Montrol’s companion fiat-to-crypto platform, WeExchange. Montrol allegedly failed to communicate the lost monies with investors or regulatory authorities. On one occasion, he promoted the operation as “commercially successful” instead of insolvent.”
Improper storage combined with a lack of transparency enabled this operation to continue for many years as an insolvent firm. This also shows the very real tendency of some exchange operators to hide key details of hacks that occur, which is why a mandated level of transparency is so critical. Regular audits alone are only effective if the results are communicated and verifiable by the general public.

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 WeExchange, these are the critical security checks that could have prevented this incident (July 2013).
- Verify all logic paths related to Other 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
