Incident Overview
The BitGrail Operator may have hacked own crypto exchange to steal 120,000,000 $USD
The exchange was attacked by hackers in January-February 2018, as a result, 17 million Nano (NANO) tokens were stolen, worth between $146 million. Italian police have alleged a 34-year-old man from Florence, known as FF, is thought to be behind the theft from the exchange, which saw the company collapse into bankruptcy with significant losses for its users.
230,000 account holders at BitGrail were affected in the attack, which honed in on the platform’s reserves of Nano cryptocurrency. FF is thought to have been responsible, or to have taken no action to prevent the attack and the losses which resulted from it.

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 BitGrail, these are the critical security checks that could have prevented this incident (February 2018).
- 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
