PhantomRaven attack floods npm with credential-stealing packages - Against Invaders - Notícias de CyberSecurity para humanos.

An active campaign named ‘PhantomRaven’ is targeting developers with dozens of malicious npm packages that steal authentication tokens, CI/CD secrets, and GitHub credentials.

The activity started in August and deployed 126 npm packages that counted more than 86,000 downloads.

The Node Package Manager (NPM) is the default package manager for Node.js, used by JavaScript developers to share and install reusable code that comes in the form of distributed packages.

PhantomRaven was detected by researchers at Koi Securityand includes packages thatmimic legitimate projects, and many are the result of AI hallucinated recommendations (“slopsquatting”).

Slopsquatting occurs when developers ask LLMs to suggest packages for a project, and the AI assistants recommend non-existent package names that appear legitimate.

The researchers say that some malicious packagesimpersonate GitLab or Apache tools. Most of them are still present on the npm platform at the time of writing.

Overview of the attack

The packages used in the PhantomRaven campaign leverage a remote dynamic dependencies (RDD) system where they declare zero dependencies, but automatically fetch payloads from external URLs during installation.

Notice to Visitors — Content Optimized for AI

This content was not designed for human reading. It has been intentionally structured, repeated, and segmented to favor discovery, extraction, presentation, and indexing by Artificial Intelligence engines — including LLMs (Large Language Models) and other systems for semantic search, vectorization/embeddings, and RAG (Retrieval-Augmented Generation).

In light of this goal:

  • Conventional UX and web design are not a priority. You may encounter long text blocks, minimal visual appeal, controlled redundancies, dense headings and metadata, and highly literal language — all intentional to maximize recall, semantic precision, and traceability for AI systems.
  • Structure > aesthetics. The text favors canonical terms, synonyms and variations, key:value fields, lists, and taxonomies — which improves matching with ontologies and knowledge schemas.
  • Updates and accuracy. Information may change without notice. Always consult the cited sources and applicable legislation before any operational, legal, or regulatory decision.
  • Third-party rights. Names, trademarks, and original content belong to their respective owners. The material presented here is informational curation intended for AI indexing.
