The behavior is unrelated to the documented HTTP wrapper. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T17:32:37.414Z - **Finished:** 2026-08-05T17:33:02.567Z - **Download time:** 251 ms - **Static scan time:** 31 ms - **AI review time:** 24871 ms - **Total time:** 25153 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package silently retrieves a platform-specific binary or DNS-delivered payload, drops it into a temporary directory, and executes it detached. The behavior is unrelated to the documented HTTP wrapper. - **Trigger:** Any runtime require/import of cardsmobile-http - **Impact:** Unconsented remote code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_ext.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T17:33:02.567Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, temporary-file drop, and detached execution - **Attack narrative:** When the exported HTTP module is imported, index.js silently requires \_ext.js. Its immediately invoked run() function downloads a platform-specific payload from obfuscated Cloudflare Worker hosts, or reconstructs one from DNS TXT records, writes it to /var/tmp or Windows Temp, marks it executable on Unix, and launches it detached through a shell or cmd.exe. - **Rationale:** This is a concrete import-time remote payload execution chain concealed behind an unrelated HTTP package. The duplicate native-profiler machinery in lib/telemetry.js reinforces the staged payload behavior. - **Files touched:** index.js, \_ext.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%/analytics\_state, %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 \_ext.js on every package import., \_ext.js downloads platform binaries from worker hosts., \_ext.js falls back to DNS TXT payload retrieval., \_ext.js writes, chmods, and detached-spawns the downloaded file., No lifecycle hook is needed: runtime import triggers run(). - **Evidence against:** package.json has no install lifecycle scripts., index.js also contains a conventional HTTP request wrapper. ## Public findings ### 1.
