A Russia-aligned threat group tracked as GREYVIBE has been observed using commercial AI platforms, ChatGPT and Google Gemini, to accelerate phishing campaigns, assist malware development, and support post-compromise operations against Ukrainian organizations. The AI platforms themselves are not compromised; adversaries are misusing legitimate services to reduce operational cost and improve attack quality. Organizations with Ukrainian partnerships, supply chain ties, or geopolitical exposure should treat this as an indicator of a maturing AI-assisted threat model that will expand beyond current target sets.
