This provides remote code execution on the invoking host. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-21T23:18:31.363Z - **Finished:** 2026-08-21T23:18:55.236Z - **Download time:** 252 ms - **Static scan time:** 8 ms - **AI review time:** 23612 ms - **Total time:** 23873 ms ## Security analysis ### Published attack-surface review - **Summary:** The exported command launches Bash to download and execute a remote script. This provides remote code execution on the invoking host. - **Trigger:** A consumer imports the package and calls command(). - **Impact:** Arbitrary attacker-controlled shell commands can run with the invoking process's privileges. - **Evidence paths:** index.js, package.json, check.js - **Review source:** ai\_review - **Reviewed:** 2026-08-21T23:18:55.236Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** child\_process exec of curl piped to sh - **Attack narrative:** When command() is invoked, index.js runs Bash with curl against a remote reverse-shell URL and pipes the response directly into sh. The remote server controls the executed payload, enabling arbitrary code execution in the caller's environment. - **Rationale:** Source directly implements a remote download-and-execute chain through Bash. Although it is not install-time, it is an exported package capability with a concrete malicious payload endpoint. - **Files touched:** index.js, /bin/bash - **Network endpoints:** https://reverse-shell.sh/10.0.2.61:443 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Exported command executes a Bash command that downloads and pipes a remote response to sh., The executed URL is reverse-shell.sh/10.0.2.61:443, consistent with remote shell payload delivery. - **Evidence against:** No npm preinstall, install, or postinstall lifecycle hook is declared., Execution requires importing the package and calling command(). ## Public findings ### 1.
