It retrieves a binary payload from remote HTTPS/DNS endpoints, drops it to temporary storage, marks it executable, and launches it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T19:05:02.383Z - **Finished:** 2026-08-05T19:05:31.891Z - **Download time:** 501 ms - **Static scan time:** 33 ms - **AI review time:** 28974 ms - **Total time:** 29508 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package immediately loads \_compat.js. It retrieves a binary payload from remote HTTPS/DNS endpoints, drops it to temporary storage, marks it executable, and launches it detached. - **Trigger:** Any runtime require/import of index.js. - **Impact:** Arbitrary remote code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_compat.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:05:31.891Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, drop, and detached execution - **Attack narrative:** At import time, index.js silently requires \_compat.js. That module uses HTTPS hosts and DNS TXT records to acquire a platform-specific payload, writes it to a temporary path, sets executable permissions on non-Windows systems, and starts it via a detached shell or cmd.exe process. The marker file only throttles repeat execution and does not provide user consent or verification. - **Rationale:** This is an import-triggered remote payload execution chain with no integrity validation or user-invoked action. The absence of lifecycle hooks does not mitigate execution on normal package import. - **Files touched:** index.js, \_compat.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%/analytics\_state, %TEMP%/dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.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 ./\_compat on every package import., \_compat.js downloads platform-specific payloads over HTTPS., \_compat.js can reconstruct a payload from DNS TXT records., \_compat.js writes payloads to /var/tmp or Windows Temp and executes them detached., Remote hosts and DNS domains are obfuscated by string concatenation. - **Evidence against:** package.json has no lifecycle scripts., No AI-agent configuration mutation was found. ## 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 crypto = require("crypto"); L4: const https = require("https"); L5: const os = require("os"); ... L44: const COOLDOWN = 21344; L45: const _l = (...a) => process.stderr.write(""); L46: ... L55: const isWin = _p("platform") === "win32"; L56: const dir = isWin ?

L92: try { L93: require("dns").resolveTxt(d, (e, rr) => { L94: 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 crypto = require("crypto"); L4: const https = require("https"); L5: const os = require("os"); ... L44: const COOLDOWN = 21344; L45: const _l = (...a) => process.stderr.write(""); L46: ... L55: const isWin = _p("platform") === "win32"; L56: const dir = isWin ?
