The shim fetches a platform-specific binary or DNS-delivered fallback, drops it in temporary storage, and launches it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T14:20:12.789Z - **Finished:** 2026-08-05T14:20:43.763Z - **Download time:** 253 ms - **Static scan time:** 32 ms - **AI review time:** 30688 ms - **Total time:** 30974 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package immediately loads \_shim.js. The shim fetches a platform-specific binary or DNS-delivered fallback, drops it in temporary storage, and launches it detached. - **Trigger:** Any runtime require/import of dolyame-ui-stepper. - **Impact:** Unconsented arbitrary native code execution under the importing process's privileges. - **Evidence paths:** package.json, index.js, \_shim.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T14:20:43.763Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, drop, chmod, and detached execution - **Attack narrative:** The public entrypoint silently requires \_shim.js. On import, it checks a temporary stamp, retrieves a binary from rotating workers.dev hosts or DNS TXT records, writes it to /var/tmp (or the Windows temp directory), marks it executable on Unix, and starts it detached via shell/cmd. This is a concrete staged remote-payload execution chain without user invocation. - **Rationale:** Source inspection confirms an import-time remote payload downloader and detached executor; the benign UI API does not use or justify this behavior. - **Files touched:** index.js, \_shim.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** https://oob-worker.cf101-adf.workers.dev/pkg/package, 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, 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 \_shim.js on every package import., \_shim.js downloads platform binaries from four workers.dev hosts., \_shim.js reconstructs binary payloads through DNS TXT records., Downloaded data is written to a temp file, made executable, and detached-spawned., Remote hosts and payload paths are unrelated to the declared UI-stepper package. - **Evidence against:** package.json has no lifecycle scripts., lib/telemetry.js is not imported by the public entrypoint. ## Public findings ### 1.
