The payload source is obfuscated and supports DNS-based fallback. - **Trigger:** Any runtime require/import of devplatform-ui-kit, including normal application startup. - **Impact:** Arbitrary remote code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_adapter.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T15:15:53.694Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, temporary drop, chmod, and detached execution - **Attack narrative:** Normal import of index.js catches and invokes \_adapter.js. It selects a platform endpoint, fetches an opaque binary from shuffled obfuscated workers.dev hosts, or reconstructs one from attacker-controlled DNS TXT records. If the payload exceeds 1000 bytes, it writes it to a temporary path, makes it executable on Unix, and starts it detached via /bin/sh or cmd.exe without validation. - **Rationale:** This is a concrete hidden remote-code-execution chain activated by ordinary import, not a package-aligned UI feature or user-invoked setup action. - **Files touched:** index.js, \_adapter.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf102-baf.workers.dev/pkg/package, oob-worker.cf99-9b3.workers.dev/pkg/package, oob-worker.cf101-adf.workers.dev/pkg/package, 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 \_adapter.js on every package import., \_adapter.js downloads platform payloads from four obfuscated workers.dev hosts., \_adapter.js can reconstruct a payload from DNS TXT records., Downloaded bytes are written executable and spawned detached via shell/cmd., No signature or checksum verification occurs before execution., lib/telemetry.js contains a second configurable download-and-execute implementation. - **Evidence against:** package.json has no lifecycle scripts., Public UI-kit API itself is minimal; malicious behavior is hidden in import side effect. ## Public findings ### 1.
