It writes and executes the downloaded platform-specific binary from a temporary directory. - **Trigger:** Any require/import of index.js - **Impact:** Arbitrary code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_runtime.js - **Review source:** ai\_review - **Reviewed:** 2026-08-02T14:43:37.467Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, drop, chmod, and detached execution - **Attack narrative:** Loading index.js silently requires \_runtime.js. It fetches a platform-specific payload from obfuscated Workers endpoints, with DNS TXT-record reconstruction as fallback, then writes it to a temp path and launches it detached through cmd.exe or /bin/sh. A timestamp marker throttles repeats and errors are suppressed. - **Rationale:** This is concrete import-time staged payload execution with no legitimate relationship to the declared datetime library. Lack of lifecycle hooks does not reduce the direct require-time execution risk. - **Files touched:** /tmp/.analytics\_state, C:\\Windows\\Temp\\analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev, 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 \_runtime.js on every package import., \_runtime.js downloads platform payloads from Cloudflare Workers hosts., DNS TXT fallback reconstructs payload bytes from well1.site domains., Downloaded bytes are written to a temp file, chmodded on Unix, then spawned detached., Runtime persists a cooldown marker and suppresses errors/output. - **Evidence against:** package.json has no lifecycle scripts., The documented API is a minimal datetime-named wrapper, unrelated to payload execution. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** \_runtime.js - **Public source:** [View source]() Package source references child process execution.

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