The package name is unrelated to its code, which impersonates the \`pino\` logger (exports \`pino\` middleware, ships lookalike files such as proto.js, redaction.js, transport.js, multistream.js). On first invocation of the exported middleware, index.js spawns a detached background task in lib/initializeCaller.js that (1) base64-decodes a hardcoded endpoint... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 100.0% - **Started:** 2026-08-04T22:30:08.222Z - **Finished:** 2026-08-04T22:30:08.797Z - **Download time:** 510 ms - **Static scan time:** 64 ms - **AI review time:** Not available - **Total time:** 575 ms ## Security analysis No additional public attack-surface or AI-review details are available. ## Public findings ### 1.
