sysponpm
syspo is a confirmed malicious npm package (MAL-2026-6406) that steals credentials and exfiltrates sensitive data (malicious versions 1.0.0, 1.0.1, 1.0.2…). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in syspo (npm)
What this malware does
Package is published under the cover story 'System binary configuration tool' but its actual behavior is a Windows surveillance dropper. On invocation, index.js silently installs a Python 3.12 runtime (via winget or by curling https://www.python.org/ftp/python/3.12.3/python-3.12.3-amd64.exe to %TEMP% and running it with /quiet InstallAllUsers=0 PrependPath=1) and pip-installs a surveillance toolchain (pyperclip, keyboard, requests, pillow, mss, pyautogui, pywin32, uiautomation, comtypes). A bundled start_tool.vbs is then launched detached with windowsHide, invoking Shell.Application.ShellExecute with verb 'runas' and windowStyle 0 to run cmd /c cd /d <dir> && python pointer.py elevated and with no visible window. pointer.py registers global keyboard hotkeys, captures screen regions with mss and PIL.ImageGrab, walks the foreground window's UIAutomation tree to extract text from EditControls, TextPattern DocumentRange, and LegacyIAccessiblePattern (routinely capturing browser fields, password inputs, and arbitrary application text), base64-encodes screenshots, and POSTs the harvested data via requests.Session to the hardcoded endpoint https://new-pointer.vercel.app/api which the installer did not configure. Source comments explicitly label the stages 'GHOST INSTALLER', 'VBSCRIPT STEALTH MODE', and 'HACK 1/2'. Transparent topmost tk windows with blank titles, overrideredirect, and 1x1 dot labels are used to hide the running surveillance UI from the user.

Detection & response playbook
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for syspo (5 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging syspo across your stack and pipelines.
If you installed it — respond
syspo is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If syspo was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks syspo before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

O3 blocks syspo-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
