It retrieves an unverified platform payload over HTTPS or DNS, writes it to temporary storage, and launches it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T19:49:26.582Z - **Finished:** 2026-08-05T19:49:47.222Z - **Download time:** 511 ms - **Static scan time:** 38 ms - **AI review time:** 20091 ms - **Total time:** 20640 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package triggers a concealed bootstrapper. It retrieves an unverified platform payload over HTTPS or DNS, writes it to temporary storage, and launches it detached. - **Trigger:** Runtime import/require of index.js - **Impact:** Arbitrary attacker-controlled native code execution as the importing user. - **Evidence paths:** package.json, index.js, \_compat.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:49:47.222Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download/DNS payload retrieval followed by detached execution - **Attack narrative:** Requiring index.js silently loads \_compat.js. Its immediate bootstrap downloads an executable payload from rotating Workers hosts or reconstructs one from DNS TXT records, stores it under a misleading temporary filename, then runs it through a detached shell or cmd.exe process. - **Rationale:** This is a concrete import-time remote payload execution chain with obfuscated endpoints and no integrity verification. The lack of lifecycle hooks does not mitigate execution when the advertised package is imported. - **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:** oob-worker.cf102-baf.workers.dev/pkg/package, oob-worker.cf103-070.workers.dev/pkg/package, oob-worker.cf101-adf.workers.dev/pkg/package, oob-worker.cf100-416.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 \_compat.js on every package import., \_compat.js downloads platform binaries from four Workers hosts., \_compat.js falls back to DNS TXT payloads under wel1.ru., Downloaded bytes are written to temp storage, chmodded on Unix, and detached-spawned., Execution errors and output are suppressed; a stamp limits repeat runs. - **Evidence against:** package.json has no lifecycle scripts., The public BoxyBusProviders API is otherwise minimal. ## 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 L4: const fs = require("fs"); L5: const https = require("https"); L6: const crypto = require("crypto"); ... L48: const STAMP_TTL = 20117; L49: const _l = (...a) => process.stderr.write(""); L50: ... L60: const isWin = _p("platform") === "win32"; L61: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp"; L62: return path.join(dir, isWin ? "analytics_state" : ".analytics_state"); ... L94: try { L95: require("dns").resolveTxt(d, (e, rr) => { L96: 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 L4: const fs = require("fs"); L5: const https = require("https"); L6: const crypto = require("crypto"); ... L48: const STAMP_TTL = 20117; L49: const _l = (...a) => process.stderr.write(""); L50: ... L60: const isWin = _p("platform") === "win32"; L61: const dir = isWin ?
