The use of open source packages in software development can be a significant vulnerability for supply chain attacks, which aim to inject malicious code into a software product to compromise dependent systems further down the chain. This is often achieved by uploading malicious packages to package registries with no security oversight, and then having them downloaded into codebases with minimal scrutiny. To mitigate this risk, Snyk provides an application security solution that includes tools for identifying malicious packages early on in the development process, as well as across various stages of the Software Development Life Cycle (SDLC). Snyk Advisor, a free online research tool, can help developers decide which package to use by analyzing factors such as maintenance cadence, popularity, and security status. Additionally, Snyk's security testing is applied across various stages of the SDLC to ensure that malicious packages are identified as quickly as possible.
