Cracking Cryptocurrency with Otto
How do you take down a cryptocurrency?
Otto Ebeling visited my penetration testing course. He told us the story of a considerable bug bounty he won and the approach he used.
When reading code (to break it), you should look at what it says, not just what coder meant. What did they assume?
Otto also gave advice on choosing a bug bounty, picking low competition / high yield areas of software to analyze, finding the bug in code and negotiating when necessary ("it's a dupe"). The presentation got great student feedback (5.0/5). It made the challenging subject easy to understand and follow.
