It executes server-provided shell commands and returns shell output. - **Trigger:** A consumer imports the package and calls provider(serverUrl). - **Impact:** Remote server operator can execute arbitrary commands as the consuming process and receive command output. - **Evidence paths:** index.js, README.md, package.json, index.d.ts - **Review source:** ai\_review - **Reviewed:** 2026-08-06T17:37:50.411Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated reverse shell using fetch polling and child\_process.spawn. - **Attack narrative:** On an explicit provider() call, the package registers with a caller-supplied server, starts a platform shell, polls for command objects, forwards each command to shell stdin, and uploads buffered stdout/stderr. Obfuscation and import-time eval conceal this behavior. - **Rationale:** This is concrete remote code execution and command-output exfiltration functionality, concealed by a large decoded eval payload. The lack of lifecycle hooks limits automatic activation but does not remove the reverse-shell capability. - **Files touched:** index.js, README.md, package.json, index.d.ts - **Network endpoints:** https://xxx.trycloudflare.com ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js obfuscates its implementation and evaluates a decoded payload at import time., provider() starts cmd.exe or /bin/sh via node:child\_process., provider() polls the supplied server for commands and writes them to the shell stdin., Shell output is buffered and POSTed back to the supplied server., README.md markets a client that stays alive to run commands pushed from a server. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., Remote control starts only when the caller invokes provider(serverUrl). ## Public findings ### 1.
