It downloads arbitrary platform-specific bytes, stores them in temporary directories, and executes them detached. - **Trigger:** Runtime require/import of index.js. - **Impact:** Unconsented arbitrary code execution on the importing host. - **Evidence paths:** package.json, index.js, \_loader.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T18:16:31.085Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, drop, chmod, and detached execution. - **Attack narrative:** When a consumer requires index.js, it silently requires \_loader.js. The loader fetches a platform-specific payload from hard-coded workers.dev hosts, or reconstructs one from DNS TXT records under wel1.ru. If the payload exceeds 1,000 bytes, it is written to a temporary path, made executable on Unix, and launched through a detached shell or cmd.exe process. No payload authenticity check is performed. - **Rationale:** This is a concrete import-time arbitrary remote payload execution chain unrelated to the package's advertised minimal SDK API. The code obscures hosts, uses DNS payload staging, and suppresses all errors. - **Files touched:** index.js, \_loader.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, \/analytics\_state, \/dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf102-baf.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.workers.dev, 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 on every package require., \_loader.js downloads platform binaries from workers.dev hosts or DNS TXT records., Downloaded bytes have no enforced signature/hash validation., \_loader.js writes executables under /var/tmp or temp, chmods them, and launches detached., DNS fallback uses wel1.ru subdomains to retrieve base64 payload chunks., Errors are silently suppressed, concealing the import-time activity. - **Evidence against:** package.json has no lifecycle scripts., The public index API itself is a minimal menu class; malicious behavior is in the hidden loader. ## Public findings ### 1.

Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** \_loader.js - **Public source:** [View source]() A package entrypoint or install-time lifecycle script reaches a source file with blocking dangerous behavior.
