Flare researchers describe an underground forum advertisement for 'Mycelium Framework,' a botnet claiming to classify infected machines by compute, GPU, stolen AI API keys and local models, then route AI inference, social engineering and other tasks accordingly. No source code or proof of execution was provided, and most individual techniques are previously documented, so the AI-as-a-service claims remain unverified.
