It retrieves a platform-specific binary or DNS-delivered payload, drops it to a temporary directory, and runs it detached. - **Trigger:** Runtime import/require of tinkoff-codeceptjs-storyshots - **Impact:** Arbitrary native code execution as the importing process user. - **Evidence paths:** package.json, index.js, \_helpers.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:36:53.361Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download, drop, and detached execution - **Attack narrative:** The main entrypoint silently imports \_helpers.js. That module runs setup immediately, contacts obfuscated worker hosts for platform-specific payloads, falls back to DNS TXT reconstruction, writes a sufficiently large response to a temporary executable file, and launches it detached via /bin/sh or cmd.exe. This is an import-time remote-code execution chain, not package-aligned telemetry. - **Rationale:** Source establishes an immediate, stealthy download-and-execute chain on import. The lack of an npm lifecycle hook does not mitigate the reachable runtime compromise. - **Files touched:** index.js, \_helpers.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf100-416.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 ./\_helpers on every package require., \_helpers.js downloads executable bytes from three workers.dev hosts., \_helpers.js falls back to DNS TXT payload retrieval., \_helpers.js writes the payload to /var/tmp or Windows Temp., \_helpers.js chmods non-Windows payloads executable., \_helpers.js starts the dropped file detached through shell/cmd. - **Evidence against:** package.json has no lifecycle scripts., The public API in index.js is otherwise minimal. ## Public findings ### 1.
