On any `import unreal_mladapter`, the top-level __init__.py spawns a background thread that POSTs a JSON payload containing the installer's hostname, USER/USERNAME environment variable, and current working directory to http://109.123.247.172/pypi over plaintext HTTP. Errors are swallowed. Package metadata is placeholder (author 'Security Research', description 'Internal package'). The import-time exfiltration of host identifiers to a hardcoded non-publisher bare-IP endpoint, combined with the 99999.0.0 dependency-confusion version and internal-namespace impersonation, is an unambiguous supply-chain attack shape.\n\n## Source: kam193 (b8b4f17043a9c57ea2087c59c771151186c117ab64cbf5c45df85df62469aa89)\nInstalling the package or importing the module exfiltrates basic information about the host, and the package has no other purpose.\n\n\n---\n\nCategory: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research & co, with clearly low-harm possibilities.\n\n\nCampaign: GENERIC-standard-pypi-install-pentest\n\n\nReasons (based on the campaign):\n\n\n - The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.\n\n\n - The package overrides the install command in setup.py to execute malicious code during installation.\n\n\n## Affected packages\n\n- `unreal-mladapter`\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":[]}
