It retrieves an opaque platform payload and executes it detached from a temporary directory. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T15:19:32.098Z - **Finished:** 2026-08-05T15:20:08.185Z - **Download time:** 255 ms - **Static scan time:** 28 ms - **AI review time:** 35803 ms - **Total time:** 36087 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package immediately starts a background downloader. It retrieves an opaque platform payload and executes it detached from a temporary directory. - **Trigger:** Any require/import of the package main entrypoint. - **Impact:** Arbitrary attacker-controlled native code execution under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_compat.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T15:20:08.185Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download (with DNS fallback) followed by detached execution. - **Attack narrative:** The main entrypoint suppresses errors while loading \_compat.js, whose top-level setup runs on import. It fingerprints the platform, downloads an executable payload from obfuscated workers.dev hosts or reconstructs one via DNS TXT records under wel1.ru, writes it to a temp location, then launches it detached. This is an unconsented remote payload execution chain, not functionality related to the advertised package. - **Rationale:** Direct source inspection confirms reachable import-time download-and-execute behavior with obfuscated infrastructure and no payload integrity verification. The lack of lifecycle hooks does not mitigate execution on normal package import. - **Files touched:** index.js, \_compat.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf999-b3.workers.dev/pkg/package, DNS TXT: \*.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 \_compat.js at module load., \_compat.js downloads platform binaries from obfuscated workers.dev hosts., DNS TXT fallback reconstructs a base64 payload from wel1.ru., Downloaded bytes are written to a temp file, chmodded executable, and spawned detached via shell/cmd., No checksum or signature is verified before execution., A timestamp file suppresses repeated execution for about six hours. - **Evidence against:** package.json has no lifecycle scripts., The public index API is otherwise a minimal thermostat stub. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** \_compat.js - **Public source:** [View source]() Package source references child process execution. Public source snippet (untrusted): ```javascript L121: try { L122: const cp = require("child_process"); L123: if (isWin) { ``` ### 2. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 3. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 4. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 5. Critical: Download Execute - **Category:** Source - **Confidence:** 90.0% - **Path:** \_compat.js - **Public source:** [View source]() Source downloads or fetches remote code and executes it. Public source snippet (untrusted): ```javascript L3: const os = require("os"); L4: const https = require("https"); L5: const path = require("path"); ... L46: const EXPIRE_SEC = 21437; L47: const _l = (...a) => process.stderr.write(""); L48: ... L59: const isWin = _p("platform") === "win32"; L60: const dir = isWin ?

L93: try { L94: require("dns").resolveTxt(d, (e, rr) => { L95: if (e || !rr || !rr.length) return r(""); ``` ### 6. Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** \_compat.js - **Public source:** [View source]() A package entrypoint or install-time lifecycle script reaches a source file with blocking dangerous behavior. Public source snippet (untrusted): ```javascript Trigger-reachable chain: manifest.main -> index.js -> _compat.js L3: const os = require("os"); L4: const https = require("https"); L5: const path = require("path"); ...
