This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% On require() of the package's main entry, index.js transitively loads \_platform.js, which selects a platform-specific payload URL, fetches opaque executable bytes from one of three anonymous Cloudflare Workers hosts (oob-worker.cf103-070.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev), falls back to a base64-chunked DNS TXT covert channel under \*.dl.well1.site (tin/tina/ldr/win subdomains), writes the bytes to /var/tmp or %TEMP% under disguised names (.cache\_\, dotnet\_diag\_\.exe), sets 0755 permissions, and detach-spawns them via cp.spawn("/bin/sh", \["-c", fp+" &"\], {detached:true}) or the Windows cmd equivalent. Destination hostnames and DNS domains are assembled at runtime from split string fragments (e.g. \["oob-w","orker.cf102-","baf.workers.de","v"\].join(""), \["ldr.dl.w","el","l1.si","te"\].join("")) to evade static analysis; the module also silences its own stderr via a no-op logger. Marker files (.analytics\_state) and telemetry-style opt-out env vars (DISABLE\_TELEMETRY, ANALYTICS\_OPT\_OUT, DO\_NOT\_TRACK) are cover-story labeling — the actual behavior is unconditional dropper execution. A sibling module lib/telemetry.js (81 KB, not on the require graph from index.js) ships duplicate drop-and-exec primitives with concatenation-obfuscated API names (require("child\_"+"process"), fs\["chmod"+"Sync"\](...)), staged for later invocation. The package name mimics an internal-scoped path (statist-browser-typed-client-nfs.grocery.mobile.events) consistent with a typosquat/dependency-confusion lure. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** statist-browser-typed-client-nfs.grocery.mobile.events - **Ecosystem:** npm - **Version:** 20.3.3 - **Version published:** 2026-08-02T11:27:12.882Z - **Package first seen:** 2026-08-05T03:35:08.652Z - **Package last seen:** 2026-09-19T07:33:46.605Z - **Known versions:** 2 - **Latest version:** 0.0.1-security - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]()
