While the description states it\u0027s a monitoring tool, the automated start, capabilities targeting secret values suggest malicious intentions.\n\n\n---\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\n\nCampaign: 2025-03-yolov8mini\n\n\nReasons (based on the campaign):\n\n\n - infostealer\n\n\n - exfiltration-generic\n\n\n - dependency-confusion\n\n\n - exfiltration-browser-data\n\n\n - The package contains code to execute remote commands (probably limited to a specific set) on the victim\u0027s machine.\n",
