China-linked SweetSpecter targeted OpenAI employees
OpenAI reported that a suspected China-linked adversary publicly tracked as SweetSpecter, active since 2023, attempted to use ChatGPT accounts and spear-phishing emails to support offensive cyber operations. In May 2024 the actor sent malicious emails with an attachment that decrypted and executed Windows malware called SugarGh0st RAT if opened; OpenAI's security controls and industry partners blocked the emails before employee inboxes were compromised. OpenAI identified and banned on-platform accounts tied to the campaign, mapped the attacker’s model-usage to LLM-themed TTPs proposed for MITRE ATT&CK, and used ChatGPT to help analyze adversary interactions. The report highlights threat-intelligence sharing and platform defenses against malicious uses of LLMs.

PRC-linked 'Tech and Tariffs' campaign targets US tech policy
OpenAI reported and removed a cluster of ChatGPT accounts likely originating in China that used the models to generate short comments, political cartoons, and bulk content to influence debates about US tech policy, tariffs, and geopolitical competition. The operators used Simplified Chinese prompts, VPNs, and terminology associated with China’s public security system; they posted generated English and other-language content via likely inauthentic X accounts and a related X network that spread false claims about ChatGPT data compromises. OpenAI assessed the activity as limited (Breakout Scale Category One) with little observable engagement and could not conclusively tie operators to formal PRC institutions. The case mirrors earlier PRC-origin influence operations targeting rare-earth companies and occurred amid heightened US–China technology tensions in late 2025–mid 2026.
