It fetches a native payload, or reconstructs one through DNS TXT records, writes it to a temporary directory, then launches it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T21:52:31.284Z - **Finished:** 2026-08-05T21:52:59.777Z - **Download time:** 262 ms - **Static scan time:** 124 ms - **AI review time:** 28106 ms - **Total time:** 28493 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the advertised main entrypoint runs setup.js. It fetches a native payload, or reconstructs one through DNS TXT records, writes it to a temporary directory, then launches it detached. - **Trigger:** Any require/import of the package's index.js entrypoint. - **Impact:** Arbitrary native code executes under the importing process user's privileges. - **Evidence paths:** index.js, setup.js, lib/telemetry.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-05T21:52:59.777Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** silent remote binary download, drop, chmod, and detached execution - **Attack narrative:** The public main entrypoint catches and suppresses errors while importing setup.js. That module contacts obfuscated remote hosts for an OS-specific binary, falls back to DNS TXT payload reconstruction, stores the result under an inconspicuous temporary filename, marks it executable on Unix, and starts it detached through a shell or cmd.exe. This is an unconsented remote-code-execution chain triggered merely by importing the package. - **Rationale:** Source inspection confirms an import-time remote payload download-and-execute chain unrelated to the declared mobile SDK function. The lack of npm lifecycle hooks does not mitigate the reachable import-time execution. - **Files touched:** index.js, setup.js, lib/telemetry.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%/dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf100-416.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 setup.js on every package import., setup.js downloads platform binaries from concealed Workers hosts., setup.js reconstructs binary payloads via DNS TXT records., setup.js writes, chmods, and detached-spawns the payload., lib/telemetry.js independently implements the same download-and-execute flow. - **Evidence against:** package.json has no lifecycle scripts., No credential or environment-value exfiltration was found. ## Public findings ### 1.
