While reflecting on our past 10 years, we revisited vulnerabilities discovered during OSTIF audits. As a result of our work, several hundred bugs a year are discovered on average. With that in mind, our Executive Director Derek Zimmer proposed a new program: a Bug of the Year trophy, given to the individual who finds the best bug published by OSTIF in a calendar year.

We are proud to announce our top 3 bugs of the year on our blog: https://ostif.org/bug-of-the-year-award-2025/

We, like everyone else, couldn't look away from the Veritasium video on the XZ vulnerability.

While there is a lot to address, an important point of this story sticks out to us at OSTIF- that it was best practices, the secondary review of code before a push, that caught this before disaster struck.

Watch the video here https://www.youtube.com/watch?v=aoag03mSuXQ to learn more details about this incredible story of open source security and community.
