Compromised @joyfill npm Packages Deliver RAT on Import
- Engineer — Act: Supply-chain compromise with import-time execution is an immediate threat to any project pulling these beta versions; audit node_modules and lockfiles for @joyfill/layouts@0.1.2-2773.beta.0 and @joyfill/components@4.0.0-rc24-2773-beta.4, remove them, and inspect CI/CD build artifacts from affected hosts for signs of RAT persistence.
- SOC/IR — Act: The DEV#POPPER malware family has prior campaign IOCs — hunt for outbound connections and process spawns originating from npm install/build steps on developer workstations and CI runners; prioritize any host that ran builds pulling @joyfill packages since these beta versions were published.
- Leader — Plan: Confirm whether engineering teams use @joyfill beta packages and use this incident to validate that npm supply chain controls — lockfiles, dependency auditing, and private registry mirroring — are enforced across your development pipeline this quarter.
