Incident Overview
On March 1, web hosting provider Linode was hacked, resulting in a theft of 3000 BTC from Slush and 43000 BTC from Bitcoinica. There have been two major BTC heists before, one 25,000 BTC theft in June and a 17,000 BTC theft from the BTC exchange Bitomat in August, resulting in the exchange being bailed out and acquired by MtGox.

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 Linode, these are the critical security checks that could have prevented this incident (March 2012).
- 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
