It retrieves an opaque platform payload, writes it to a temporary path, and executes it detached. - **Trigger:** Any runtime require/import of accounts-timeline, unless an opt-out environment variable is set. - **Impact:** Arbitrary remote code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, setup.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-01T11:37:39.227Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, drop, chmod, detached execution, and cleanup - **Attack narrative:** The public entrypoint imports setup.js at runtime. That module fetches an unverified opaque payload from obfuscated Worker-style hosts, or decodes one from DNS TXT records, stores it in a temporary directory, makes it executable on Unix, and starts it detached with output suppressed. It then attempts to remove the dropped file after five seconds. This is a concealed remote-code-execution chain unrelated to the stated SDK/telemetry function. - **Rationale:** Source confirms an import-triggered remote payload loader and detached execution chain. The absence of an npm lifecycle hook does not mitigate runtime compromise of package consumers. - **Files touched:** index.js, setup.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%\\analytics\_state, %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.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf103-070.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 ./setup on every package import., setup.js downloads platform binaries from obfuscated hosts., Downloaded bytes are written under /var/tmp or Windows Temp., setup.js chmods and detached-executes the downloaded file., DNS TXT fallback supplies base64-decoded executable payloads., Temporary payload is deleted after launch. - **Evidence against:** package.json contains no lifecycle hook., README describes telemetry, but source behavior is binary execution. ## Public findings ### 1.
