Software Supply Chain Risk in Package Managers, Including AI-Driven Slopsquatting

ENISA published a March 2026 technical advisory on the secure use of package managers, warning that modern development workflows (e.g., npm, pip, Maven) can pull in far more code than developers expect due to direct and transitive dependency resolution. The advisory highlights how applications inherit large dependency graphs—often including unused modules—that still introduce vulnerabilities, maintenance and provenance risk, and expanded trust assumptions across the software supply chain. ENISA recommends secure practices for selecting, integrating, monitoring, and remediating vulnerable third-party dependencies as part of the SDLC.

Separately, security researchers and industry commentary describe slopsquatting, a supply-chain technique that exploits AI coding assistants’ tendency to hallucinate plausible-but-nonexistent package names. Attackers can register those “phantom” names in public repositories and publish packages that appear to match the expected functionality while embedding malicious payloads, turning AI-generated suggestions into a predictable package-name acquisition strategy. The risk is positioned as distinct from typosquatting (human error) and is framed as requiring additional detection approaches beyond traditional controls, including more behavioral and validation-focused checks before adopting AI-suggested dependencies.
