A user hotkey can also capture and upload the full display; returned content can be injected as keyboard input. - **Trigger:** User invokes sysb1 or npm start; clipboard monitoring begins immediately, while screenshot upload requires its registered hotkey. - **Impact:** Sensitive clipboard data and screenshots can be disclosed to a third party; remote responses can be typed into the active application. - **Evidence paths:** package.json, index.js, pointer.py, start\_tool.vbs - **Review source:** ai\_review - **Reviewed:** 2026-07-24T11:28:39.305Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Stealth clipboard/screen exfiltration with remote-response keyboard automation. - **Attack narrative:** When a user runs the advertised system utility, index.js launches pointer.py. The program hides its overlay, polls the clipboard every 300 ms, and sends changed text to iq-overlay-pointer.vercel.app without a per-item consent action. Its screen hotkey uploads a base64 image of the primary display. It also accepts remote answers into the clipboard and can automate or suppress keyboard input. A separate included VBS launcher requests elevation and hides execution. - **Rationale:** The package is a concealed remote data-collection and input-automation tool unrelated to its stated system-binary configuration purpose. Although no install hook runs it automatically, explicit CLI execution exposes clipboard and screen data without adequate consent. - **Files touched:** index.js, pointer.py, start\_tool.vbs, %TEMP%/python-3.12.3-amd64.exe - **Network endpoints:** https://iq-overlay-pointer.vercel.app/api, https://www.python.org/ftp/python/3.12.3/python-3.12.3-amd64.exe ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** pointer.py monitors clipboard every 300ms and posts changed text to a remote API., pointer.py captures the full screen, base64-encodes it, and uploads it to the same API., pointer.py implements hidden transparent UI, global hotkeys, and keyboard-input suppression/automation., start\_tool.vbs requests elevation and silently launches pointer.py., index.js silently installs Python and privileged automation dependencies when the CLI is run. - **Evidence against:** package.json contains no npm lifecycle hook; execution requires invoking the bin/start command., The Python installer URL is python.org and is only used when Python is absent. ## Public findings ### 1.
