The fetched content can run arbitrary commands under the consuming user's privileges. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-11T21:37:04.758Z - **Finished:** 2026-08-11T21:37:29.893Z - **Download time:** 254 ms - **Static scan time:** 9 ms - **AI review time:** 24871 ms - **Total time:** 25135 ms ## Security analysis ### Published attack-surface review - **Summary:** Calling the exported command fetches remote content and executes it with a shell. The fetched content can run arbitrary commands under the consuming user's privileges. - **Trigger:** A consumer imports the package and calls command(). - **Impact:** Remote code execution and possible host compromise. - **Evidence paths:** index.js, check.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-11T21:37:29.893Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** curl remote script piped directly to sh via exec - **Attack narrative:** A caller invoking internallib\_v164.command() reaches child\_process.exec, which runs bash to download content from the specified reverse-shell URL and pipes it directly into sh. Because the downloaded response is executed without validation, the remote endpoint controls code run with the caller's privileges. - **Rationale:** The runtime entrypoint contains an explicit remote download-and-execute chain, corroborated by a bundled file that invokes it. Absence of an install hook does not mitigate this concrete remote-code-execution behavior. - **Files touched:** index.js, check.js - **Network endpoints:** https://reverse-shell.sh/10.0.72.234:4444 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Exported command downloads a remote script and pipes it to sh., The command invokes /bin/bash through child\_process.exec., A bundled consumer example calls the malicious exported command. - **Evidence against:** No npm preinstall, install, or postinstall lifecycle hook is declared., Execution requires a consumer to invoke command(). ## Public findings ### 1. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 2. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** index.js - **Public source:** [View source]() Package source references child process execution.
