Maintainer Burnout and the Human Weakness in Open Source
One of the most dangerous myths in software security is that supply chain risk is mainly a code problem. Sometimes it is a human fatigue problem first. In Twenty Twenty-Four, the xz Utils backdoor attempt showed that clearly: a deeply embedded compression library, a long-trusted project, and a maintainer, Lasse Collin, who had been carrying too much of the load for too long. The exploit itself was sophisticated. The opening was more ordinary. A critical project had too little slack, too little support, and too much trust concentrated in too few hands.

This pattern did not begin with xz. In Twenty Eighteen, the npm package event-stream was handed to a new maintainer and later used to smuggle malicious code aimed at users of the Copay cryptocurrency wallet. In Twenty Twenty-Two, the maintainer behind colors.js and faker.js sabotaged his own packages after years of frustration over unpaid dependency labor. These were different stories with different motives, but they pointed at the same structural weakness: modern software depends on small components maintained by people who are often exhausted, isolated, or treated like invisible infrastructure.
That is what leaders still miss. Open source risk is not only about whether a package has a vulnerability. It is also about whether the people behind it have enough time, backup, funding, review support, and institutional respect to keep making good decisions. An overworked maintainer may not need to turn malicious to become part of the risk story. They only need to be tired enough to miss the wrong commit, accept the wrong helper, or walk away at the wrong moment.
The supply chain runs on code, but it is governed by human attention. If a dependency is critical to your business, but its future still depends on one burned-out maintainer working nights and weekends, is that really someone else’s risk?
