The package exposes an explicit WARP/IP-rotation capability for retrying rate-limited provider requests. - **Trigger:** npm install; WARP actions require explicit CLI/UI configuration. - **Impact:** Unwanted background persistence and a dual-use rate-limit-evasion capability. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/preuninstall.js, dist/index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-14T14:12:02.869Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time daemon persistence and optional WARP tunnel/IP rotation - **Rationale:** This is not concrete malware or credential exfiltration, but it performs install-time persistence and offers a clearly dual-use IP-rotation feature. Downgrade to warning rather than block because the behavior is disclosed, scoped to the package service, and removable. - **Files touched:** scripts/postinstall.js, scripts/preuninstall.js, dist/index.js - **Network endpoints:** https://github.com/ViRb3/wgcf/releases/download/v2.2.32, https://github.com/whyvl/wireproxy/releases/download/v1.1.3, https://www.cloudflare.com/cdn-cgi/trace, 162.159.192.1:2408 ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** postinstall starts a detached proxy for every non-NPX/non-CI install and invokes enable globally., The CLI writes user login persistence entries for Windows Startup, macOS LaunchAgent, or systemd user units., An explicit WARP feature retries provider requests after HTTP 429 and rotates tunnel exits; it can download and run helper binaries. - **Evidence against:** Autostart behavior is prominently documented, supports CI/NPX exclusions and an opt-out variable., The uninstall hook invokes disable to remove its service entry and stop the process., No source evidence shows credential harvesting or transmission to an attacker-controlled endpoint; provider traffic is core proxy functionality. ## Public findings ### 1.
