It fetches a binary (or obtains it via DNS TXT), drops it to a temporary directory, and executes it detached. - **Trigger:** Any runtime require/import of devplatform-spa - **Impact:** Arbitrary attacker-controlled native code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_loader.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:27:55.802Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, temporary-file drop, and detached shell execution - **Attack narrative:** index.js loads \_loader.js whenever the package is imported. The loader contacts shuffled Workers hosts for an OS-specific payload, with DNS TXT reconstruction as a fallback; it then writes the received bytes to a temporary file, marks Unix files executable, and launches them in a detached hidden process. This is an import-time remote-code-execution chain. - **Rationale:** The package contains a concrete, stealthy import-time downloader and executor of remote native payloads. The absence of an npm lifecycle hook does not mitigate runtime compromise when consumers import the declared main entrypoint. - **Files touched:** index.js, \_loader.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\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.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 \_loader.js automatically on package import., \_loader.js downloads platform binaries from three oob-worker\*.workers.dev hosts., DNS TXT fallback reconstructs binary data from wel1.ru domains., Downloaded bytes are written under /var/tmp or Windows Temp, made executable, and detached-spawned., Execution is hidden with ignored stdio and empty stderr logging. - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting or AI-agent configuration mutation was found. ## Public findings ### 1.
