5 Best SCA Tools for Detecting Malicious Open-Source Packages
Compare five SCA tools for detecting malicious open-source packages, from behavioral analysis and install-time blocking to threat intelligence.
Five leading Software Composition Analysis (SCA) tools are available for detecting malicious open-source packages. These tools employ distinct methods to identify security risks within software components. The first tool, Aikido Security, addresses two critical issues. While most scanners focus on known flaws, Aikido identifies malicious packages that contain intentional malicious code.
It utilizes a four-layer exploitability analysis, including dependency, function, contextual, and exploitability assessments. Aikido also leverages the Aikido Intel feed, which contains over twelve thousand known malicious packages. Another tool, Socket, monitors the behavior of code in real-time rather than solely relying on a list of banned names.
It inspects packages themselves, detecting suspicious behavior such as reading sensitive files, using obfuscation techniques, or lacking a matching source repository. Socket operates on a package reputation system, giving lower scores to packages from less established maintainers even if they trigger individual signals. The Socket Firewall blocks malicious packages at the install time, preventing them from reaching the user's machine or CI pipeline.
Lastly, SafeChain is an open-source SCA tool that operates as a CLI and can be integrated into a developer's workflow or CI pipeline. It offers a safe one-click SBOM generation with support for various languages and package managers, including npm, Yarn, pnpm, pip, Poetry, Maven, Gradle, sbt, NuGet, Bundler, Composer, Go modules, Cargo, CocoaPods, SwiftPM, and pub packages.
