Attacks like those experienced by SolarWinds and CodeCov show that adversaries can employ social engineering to execute supply chain attacks, as demonstrated by the backdoor introduction in the XZ Utils open source utility. This incident, along with warnings from the Open Source Security Foundation, highlights the need for vigilance in safeguarding open source projects.
The meeting notes highlight a concerning trend in the open source software supply chain, where adversaries have been exploiting social engineering tactics to introduce backdoors and malicious code into widely used projects and components. The incident with the XZ Utils open source data compression utility in Linux systems serves as an example, where individuals using multiple personas pressured the maintainer into granting commit access to introduce the backdoor.
The attack involved a prolonged and covert manipulation of the XZ Utils project, with personas such as “Jia Tan,” “Jigar Kumar,” “Dennis Ens,” and “Hans Jansen” working to gain control and introduce the backdoor binary into the utility. The coordinated effort to gradually pressure the maintainer and integrate malicious code underscores the need for heightened vigilance and early threat recognition within the open source community.
The Open Source Security Foundation (OSSF) and OpenJS Foundation have issued alerts urging open source maintainers to be alert for social engineering takeover attempts and to take steps to protect their projects. The incident serves as a reminder of the challenges in maintaining the security and integrity of open source projects, highlighting the importance of additional data sources and investigations to uncover the identities and tactics involved in such attacks.
It’s crucial for the open source community to recognize the vulnerabilities exposed by this incident and take proactive measures to safeguard against future social engineering attacks in the software supply chain.
