It downloads a platform-specific payload, stores it in a temporary directory, and runs it detached. - **Trigger:** Any runtime require/import of the package entrypoint. - **Impact:** Unconsented arbitrary native code execution under the importing process's user account. - **Evidence paths:** package.json, index.js, \_loader.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:59:55.068Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, DNS fallback, temporary-file staging, and detached shell execution. - **Attack narrative:** The public entrypoint silently requires \_loader.js. On import, it creates a cooldown stamp, fetches a platform-specific binary from rotating external hosts, or reconstructs it from DNS TXT records. It writes the received bytes to a temporary file, marks it executable on Unix, and launches it through a detached shell or cmd.exe. This is an unverified remote payload execution chain unrelated to the advertised event-bus API. - **Rationale:** The package's normal import path provides an immediate, unverified download-and-execute capability. Obfuscated endpoint construction, DNS payload fallback, and detached execution establish concrete malicious behavior. - **Files touched:** index.js, \_loader.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf101-adf.workers.dev/pkg/package, tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js imports \_loader.js during normal package import., \_loader.js downloads platform binaries over HTTPS., It falls back to DNS TXT payload retrieval., Downloaded bytes are written to /var/tmp or TEMP, chmodded, and spawned detached., Hosts and payload domains are obfuscated by string splitting., No checksum, signature, or user action gates remote execution. - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting was found in the entrypoint path. ## Public findings ### 1.

Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** \_loader.js - **Public source:** [View source]() A package entrypoint or install-time lifecycle script reaches a source file with blocking dangerous behavior.
