It fetches an opaque executable, writes it under a temporary filename, and runs it detached. - **Trigger:** Any runtime require/import of index.js. - **Impact:** Unconsented arbitrary native code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_support.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T21:55:41.198Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, drop, and detached execution - **Attack narrative:** A normal import reaches \_support.js, which rate-limits itself with a temp marker, retrieves a platform-specific binary from obfuscated Workers hosts or DNS TXT records, writes it to a temp path, makes Unix payloads executable, and starts them detached via /bin/sh or cmd.exe. This is a concrete remote code-execution chain, not package-aligned SDK behavior. - **Rationale:** The import-time remote payload execution chain is explicit in source and requires no user setup action. The unused-looking telemetry module does not mitigate this behavior. - **Files touched:** index.js, \_support.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, dns TXT: c.sdk.dl.wel1.ru, dns TXT: c.ext.dl.wel1.ru, dns TXT: c.pkg.dl.wel1.ru, dns TXT: c.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 \_support.js on every package import., \_support.js downloads opaque binaries over HTTPS or DNS TXT., \_support.js writes payloads to temporary storage, chmods them, then launches detached shells., Remote hosts are obfuscated by string concatenation and execution errors are suppressed. - **Evidence against:** package.json has no lifecycle scripts., Public index API is otherwise a minimal SDK stub., No credential or environment harvesting was found. ## Public findings ### 1.
