Over the past few years, software supply chain attacks have surged, raising significant cybersecurity concerns as attackers insert malicious code into trusted software or hardware to infiltrate organizations further down the chain. This article explores the intricacies of these attacks, highlighting how modern applications, composed of numerous layers of open-source libraries and components, present complex vulnerabilities. Notable incidents such as the SolarWinds, Codecov, and EventStream attacks illustrate different vectors of compromise—from trusted systems with privileged access to software deployment tools and dependencies—demonstrating the attackers' strategic targeting of high-value assets. Although achieving complete security is impossible, organizations can mitigate risks by adopting best practices like using trusted dependencies, scanning for vulnerabilities, implementing intelligent patching, segmenting networks, enforcing advanced authentication with least privilege access, and ensuring code repositories are free from secrets. These measures aim to limit the damage and reduce the likelihood of becoming a victim, acknowledging the interconnected nature of today's software ecosystems.
