OpenAI blocks state-sponsored hackers from using ChatGPT

OpenAI removed accounts associated with state-sponsored threat groups (e.g., Forest Blizzard/Strontium, Emerald Sleet/Thallium, Crimson Sandstorm/Curium, Charcoal Typhoon/Chromium, Salmon Typhoon/Sodium) after Microsoft provided intelligence showing these actors used ChatGPT for military- and intelligence-related research, spear-phishing content, tooling/scripting assistance, and evasion techniques; the report states the usage was mainly exploratory and supportive rather than direct malware development, and OpenAI and Microsoft will continue monitoring and disrupting such abuses of LLMs.
