The payload source is selected per platform with DNS TXT fallback. - **Trigger:** Any runtime require/import of the package main entrypoint. - **Impact:** Arbitrary attacker-controlled native code can run with the importing process user's privileges. - **Evidence paths:** package.json, index.js, \_bootstrap.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T18:56:16.340Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary staging and detached shell execution. - **Attack narrative:** Requiring index.js loads \_bootstrap.js inside a swallowed error handler. That module silently fetches a platform-specific binary from obfuscated Workers endpoints, or reconstructs one from DNS TXT records under wel1.ru; it writes the bytes to a temporary executable file and launches it detached through cmd.exe or /bin/sh. A timestamp file limits repeat execution and opt-out-like environment variables disguise the behavior as telemetry. - **Rationale:** The package's import-time bootstrap is a concrete remote-code-execution chain unrelated to its declared React button functionality. Lack of an npm lifecycle hook does not mitigate execution on normal import. - **Files touched:** index.js, \_bootstrap.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.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 \_bootstrap.js on every package import., \_bootstrap.js downloads platform-specific payloads over HTTPS or DNS TXT., \_bootstrap.js writes payloads to /var/tmp or Windows Temp, chmods Unix files, then launches them detached., Endpoints are obfuscated Workers hosts with DNS fallback under wel1.ru., Execution is silent and rate-limited via a temporary stamp file. - **Evidence against:** package.json has no lifecycle scripts., The exported button class in index.js is otherwise minimal. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** \_bootstrap.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:** \_bootstrap.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 os = require("os"); ... L46: const COOLDOWN = 19882; 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:** \_bootstrap.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 -> _bootstrap.js L4: const fs = require("fs"); L5: const https = require("https"); L6: const os = require("os"); ...
