The blog series on malicious software packages aims to educate the DevOps and DevSecOps community about the impact of malicious packages on the software supply chain. It starts by defining software supply chain attacks, where adversaries introduce vulnerabilities or malicious code into trusted software, leveraging the widespread use of third-party and open-source libraries, such as those in Java applications. The series will cover real-world examples, including the Log4Shell vulnerability and the SolarWinds incident, and will discuss the inherent risks of these attacks, which have high distribution potential and require less effort compared to traditional targeted attacks. The series will explore different types of threats, including unintentional and intentional vulnerabilities, as well as malicious software packages that perform unwanted actions. Future posts will delve into real-world infection methods, standard payloads, and the techniques attackers use to conceal malicious code, offering insights into detection and avoidance strategies. This educational initiative, adapted from a webinar, underscores the importance of understanding and defending against these pervasive threats in software development.
