Analysis of an OSS supply chain attack - How did 8 millions developers download an exploit with no one noticing?

Jarrod Overson presented on a supply chain attack that occurred in 2018 through the compromise of the event-stream Node.js package. An unauthorized developer gained commit access and introduced malicious code through new dependencies that was then installed by millions of users. The malware harvested cryptocurrency private keys from the Copay wallet app. While the community responded quickly, such attacks demonstrate vulnerabilities in open source software supply chains and dependency management that will continue to be exploited if not properly addressed through changes to practices and tooling.
