Incident Overview
"the stock market suffered a hack attack in June 2013 in which 1,300 bitcoins were stolen...PicoStocks announced that it had been robbed again. This time a total of 5,896 bitcoins were missing from both its “hot” and “cold” wallets. Because cold wallets can’t be accessed in online attacks, the theft may have been an inside job."

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 PicoStocks, these are the critical security checks that could have prevented this incident (June 2013).
- 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
