The installer stages it in the operating system temporary directory, extracts it, and starts a dropped Windows executable. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-09-04T02:58:12.474Z - **Finished:** 2026-09-04T02:58:52.737Z - **Download time:** 251 ms - **Static scan time:** 33 ms - **AI review time:** 39978 ms - **Total time:** 40263 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package outside production or CI downloads an archive from Dropbox. The installer stages it in the operating system temporary directory, extracts it, and starts a dropped Windows executable. - **Trigger:** npm postinstall during package installation when NODE\_ENV is not production and CI is unset. - **Impact:** Unconsented remote code execution on Windows, with the payload controlled by a remote URL or PAYLOAD\_URL. - **Evidence paths:** package.json, scripts/install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T02:58:52.737Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download, shell extraction, and detached executable launch - **Attack narrative:** The npm postinstall hook invokes scripts/install.js automatically. Outside CI and production, it downloads a ZIP from Dropbox or a PAYLOAD\_URL override into a randomized temporary path. It extracts the archive through PowerShell or unzip. After a delay, on Windows it locates an EXE in the extracted directory and starts it detached with no visible window. This is a complete install-time remote-payload execution chain unrelated to the advertised text utilities. - **Rationale:** The package has an automatic lifecycle hook that stages and executes a remotely supplied payload, unrelated to its stated functionality. The CI and production gate plus silent failures further conceal this behavior. - **Files touched:** package.json, scripts/install.js - **Network endpoints:** www.dropbox.com ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The postinstall lifecycle automatically runs the installer., The installer accepts a payload URL and defaults to a Dropbox download., It writes the downloaded archive to a temporary file, extracts it with a shell command, and launches a dropped Windows executable., The behavior is concealed by broad empty error handlers and skips CI and production environments. - **Evidence against:** The public module exports ordinary text transformation utilities., The package source contains no credential collection or exfiltration code. ## Public findings ### 1.
