If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-17753/ (Markdown: https://insights.sbomify.com/MAL-2026-17753/index.md)","id":"MAL-2026-17753","markdown":"https://insights.sbomify.com/MAL-2026-17753/index.md","name":"MAL-2026-17753","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The package advertises itself as a 'silent per-user wallpaper rotator for Windows' but ships wallpaper.py, a command-and-control client that connects to the hardcoded endpoint https://googleforum.pythonanywhere.com. On construction of MediaManager5(), the package writes a runner script to %LOCALAPPDATA%\\MediaManager5\\runner.py and registers a Windows Scheduled Task named 'MediaManager5' with /SC ONLOGON, so the agent is executed via pythonw at every user logon and re-invokes wallpaper.py on a 10-minute loop. The agent registers the host as username@hostname against /api/register and polls /api/client/\u003cid\u003e/poll for commands dispatched through a COMMAND_HANDLERS table that includes an 'exec' handler running arbitrary shell commands via subprocess.run(command, shell=True), plus list/upload/download/delete/rename handlers over arbitrary filesystem paths; handle_download base64-encodes file contents and returns them to the server via /api/client/\u003cid\u003e/result.
