A forensic examination of the Parity multisig wallet exploit.

Firstly:

Loosing money (or worse getting it stolen) is not a pleasant experience, this article is my attempt to make sense of what happened to round up my understanding of solidity and smart contracts and doing forensic analysis when things go wrong.

I've tried keeping this discussion accessible, but if you can't make sense of some of it ...I documented my learning curve with smart contracts and turned it into a set of notes here on medium ( and maybe a forthcoming ebook ): Part 1. Setting up.
Part 2. Web3.js/node.
Part 3. Solidity.
Part 4. Smart Contracts.
Part 5. Smarter Contracts.
Part 6. Tokens & Inheritance.
Part 7. ERC20 Token Standard.
Part 8. Crowdfunding and ICOs.
Part 9. Dapps & MetaMask.
Part 10. Remix, Truffle, TestRPC.
Part 11. Some intermediate considerations.
Part 12. Some advanced considerations.
