Summary

Attackers are compromising open source packages to spread malware. Cyber defenders are asked to review Modern software development has transformed how software is created, shared and reused – but recent attacks on these tools highlight the rapidly growing risks of using modern software ecosystems. Attackers are compromising open source packages at scale to spread malware in ways that can be difficult to detect and can do extensive damage. This blog, aimed at cyber security professionals, exposes the insidious nature of recent attacks, underlining the growing threat from software supply chains, and how attackers are able to exploit them. We explain how organisations can check if they have been affected by such a supply chain attack, and recommend actions to take to mitigate compromise and This blog helps cyber defenders to better understand, mitigate and more effectively respond to the new open source Software supply chain attacks are evolving Widely used platforms and ecosystems enable developers to develop, collaborate and re-use software at a global scale. This allows teams to build software faster and reuse widely trusted components, that are secure, reliable and maintainable.
