Previously we had attackers using hijacked npm libraries to steal credentials. In this case the libraries or the maintainer wasn’t compromised. In fact it was the maintainer who deliberately introduced bugs into his libraries, thereby breaking thousands of apps that depends on it. There’s no easy solution to this dependency problem. For now use pinned versions and manually approve upgrades.
Users of popular open-source libraries ‘colors’ and ‘faker’ were left stunned after they saw their applications, using these libraries, printing gibberish data and breaking. Some surmised if the NPM libraries had been compromised, but it turns out there’s more to the story.
