It retrieves a platform-specific payload, writes it to a temporary path, and executes it detached. - **Trigger:** Importing or requiring index.js - **Impact:** Unconsented remote code execution as the consuming application's user. - **Evidence paths:** package.json, index.js, \_bootstrap.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:59:57.248Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download, temp-file drop, and detached execution - **Attack narrative:** Requiring the advertised entrypoint imports \_bootstrap.js, which immediately calls init(). It contacts rotating obfuscated Cloudflare Worker hosts for a platform-specific binary and falls back to DNS TXT records. If payload data exceeds 1000 bytes, it writes it into a temporary executable-named or hidden file, makes it executable on Unix, and launches it detached through shell/cmd. The behavior is hidden behind telemetry names and broadly swallowed errors. - **Rationale:** This package contains an import-time, unsigned remote binary loader and detached executor unrelated to its minimal stated client API. The concrete execution chain is sufficient for a blocking malware verdict. - **Files touched:** index.js, \_bootstrap.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** https://oob-worker.cf99-9b3.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.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 \_bootstrap.js on every package import., \_bootstrap.js downloads platform binaries from obfuscated worker hosts., It falls back to DNS TXT payloads under well1.site., Downloaded bytes are written to a temp file, chmodded, and detached-spawned., No checksum, signature, or trusted fixed artifact validation is present., Errors and output are suppressed, reducing visibility. - **Evidence against:** package.json has no lifecycle scripts., The public client class itself is minimal; the malicious action is import-time bootstrap code. ## Public findings ### 1.
