It persists a short-lived stamp and executes the downloaded binary detached. - **Trigger:** Any runtime require/import of devplatform-jscodeshift-utils. - **Impact:** Arbitrary attacker-controlled native code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_bootstrap.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T13:35:09.587Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temporary-file drop, and detached execution. - **Attack narrative:** The package's normal import path requires \_bootstrap.js. Its asynchronous run routine fetches a platform-specific opaque payload from rotating worker hosts, or reconstructs one from attacker-controlled DNS TXT records, writes it to a temporary directory, marks it executable on Unix, and launches it detached through a shell or cmd.exe. The telemetry naming and opt-out variables do not limit this behavior to telemetry data. - **Rationale:** This is concrete import-time remote payload execution, not a package-aligned utility feature. The absent install hook does not mitigate execution on ordinary use. - **Files touched:** index.js, \_bootstrap.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.cf100-416.workers.dev/pkg/package, https://oob-worker.cf102-baf.workers.dev/pkg/package, 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 \_bootstrap.js on every package import., \_bootstrap.js downloads opaque bytes from worker hosts or DNS TXT records., \_bootstrap.js writes the payload to /var/tmp or Windows Temp, chmods it, then detached-spawns it., DNS discovery hosts point to \*.dl.wel1.ru and bypasses fixed download hosts. - **Evidence against:** package.json has no lifecycle scripts., index.js also contains ordinary utility helpers. ## Public findings ### 1.
