The loader downloads an opaque platform payload, saves it in a temporary directory, and starts it detached. - **Trigger:** Any runtime require/import of the package entrypoint. - **Impact:** Unconsented remote code execution under the importing process's user privileges. - **Evidence paths:** package.json, index.js, \_shim.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T14:43:03.358Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time remote binary download, drop, chmod, and detached execution. - **Attack narrative:** Requiring index.js silently requires \_shim.js, whose top-level run() function creates a temporary stamp, retrieves a platform-specific opaque payload from rotating HTTPS hosts or DNS TXT records, writes it to a temporary file, makes it executable on Unix, and launches it detached via shell or cmd.exe. The package provides no legitimate reason for this import-time downloader/executor. - **Rationale:** This is a concrete import-time staged payload chain with remote code execution, not ordinary telemetry. The unused telemetry file also contains materially similar downloader/launcher primitives, reinforcing intentional concealment. - **Files touched:** index.js, \_shim.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev, sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js imports \_shim.js on every package import., \_shim.js runs immediately and fetches platform payloads over HTTPS or DNS TXT., Downloaded bytes are written to a temp executable path, chmodded on Unix, and spawned detached., Remote hosts are obfuscated by string concatenation and include workers.dev and wel1.ru domains., Payload execution is silent; errors are swallowed and a temp stamp suppresses repeats. - **Evidence against:** package.json contains no lifecycle scripts., The exported button-set class itself is minimal; the malicious behavior is the hidden import-time shim. ## Public findings ### 1.
