Schneier - Distributing Malware By Becoming an Admin on an Open-Source Project

The module "event-steam" was infected with malware by an anonymous someone who became an admin on the project.

Cory Doctorow points out that this is a clever new attack vector:

Many open source projects attain a level of "maturity" where no one really needs any new features and there aren't a lot of new bugs being found, and the contributors to these projects dwindle, often to a single maintainer who is generally grateful for developers who take an interest in these older projects and offer to share the choresome, intermittent work of keeping the projects alive.

Ironically, these are often projects with millions of users, who trust them specifically because of their stolid, unexciting maturity.

This presents a scary social-engineering vector for malware: A malicious person volunteers to help maintain the project, makes some small, positive contributions, gets commit access to the project, and releases a malicious patch, infecting millions of users and apps.
