+Julien Malka of the [Institut Polytechnique de Paris](https://www.ip-paris.fr/) published an exciting paper this month on [*How NixOS could have detected the XZ supply-chain attack for the benefit of all thanks to reproducible-builds*](https://hal.science/hal-05326226). Julien outlines his paper as follows:
> In March 2024, a [sophisticated backdoor was discovered in xz](https://en.wikipedia.org/wiki/XZ_Utils_backdoor), a core compression library in Linux distributions, covertly inserted over three years by a malicious maintainer, Jia Tan. The attack, which enabled remote code execution via ssh, was only uncovered by chance when Andres Freund investigated a minor performance issue. This incident highlights the vulnerability of the open-source supply chain and the effort attackers are willing to invest in gaining trust and access. In this article, I analyze the backdoor’s mechanics and explore how bitwise build reproducibility could have helped detect it.
