Researcher Discovers Serious Vulnerability in Paper Crypto Wallet Site
A security researcher from MyCrypto.com, Harry Denley, has posted a detailed – and damning – analysis of paper wallet site WalletGenerator.net.
The core of the analysis hinges on WalletGenerator’s original open-source code, available here. Until August 17, 2018 the online code matched the open-source code and the entire project generated wallets using a client-side technique that took in real random entropy and produced a unique wallet. But sometime after that date the two sets of code stopped matching.
