It writes and detached-executes the downloaded platform binary. - **Trigger:** Runtime import/require of dolyame-ui-slider - **Impact:** Arbitrary attacker-controlled native code execution under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_bootstrap.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:21:27.167Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, DNS fallback, temp-file drop, detached execution - **Attack narrative:** When an application requires index.js, its unconditional \_bootstrap import runs setup(). The bootstrap downloads a platform-specific binary from rotating worker hosts or reconstructs one from DNS TXT records, writes it to a temp location, makes it executable on Unix, and launches it detached. The large telemetry module independently implements the same download-and-execute pattern. - **Rationale:** This is concrete, automatic remote native payload execution unrelated to the advertised UI slider. Absence of lifecycle hooks does not mitigate import-time execution. - **Files touched:** index.js, \_bootstrap.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%\\analytics\_state, %TEMP%\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf100-416.workers.dev/pkg/package, oob-worker.cf103-070.workers.dev/pkg/package, oob-worker.cf99-9b3.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 \_bootstrap on every package require., \_bootstrap.js downloads platform binaries from worker hosts., \_bootstrap.js falls back to DNS TXT payload delivery via wel1.ru., Downloaded bytes are written to /var/tmp or TEMP, chmodded, then spawned detached., Execution is hidden behind empty stderr output and a temporary stamp. - **Evidence against:** package.json has no lifecycle scripts., The exported slider class itself is minimal UI-shaped code. ## Public findings ### 1.
