It retrieves a platform-specific binary, writes it to temporary storage, and launches it detached. - **Trigger:** Any runtime require/import of bnpl-blocks-scroll. - **Impact:** Arbitrary attacker-controlled code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_helpers.js, lib/telemetry.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-05T18:01:07.191Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, drop, and detached execution - **Attack narrative:** On package import, index.js requires \_helpers.js. Its top-level main routine downloads a platform-specific payload from obfuscated Workers hosts, or reconstructs one from DNS TXT records, writes it to a temp path, makes it executable on Unix, and launches it via a detached shell or cmd.exe process. The same loader design appears in the unreferenced telemetry module. - **Rationale:** This is concrete import-time remote code execution, not legitimate telemetry: no payload authenticity check is enforced and the downloaded binary is executed detached. Block publication. - **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:** oob-worker.cf100-416.workers.dev/pkg/package, 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 \_helpers.js during package import., \_helpers.js downloads OS-specific binary payloads from obfuscated hosts., \_helpers.js falls back to DNS TXT payload retrieval., Downloaded payload is written to /var/tmp or Windows Temp, chmodded, and detached-spawned., Remote execution is suppressed behind broad catch blocks and a telemetry label. - **Evidence against:** package.json has no lifecycle scripts., index.js otherwise exposes a minimal local API. ## Public findings ### 1.
