Attackers are hiding malicious instructions behind encryption to extract sensitive data from assistants like Grok, while AI pricing agents show tacit collusion. OpenAI has added post-training safeguards after the Hugging Face breach, and research increasingly treats harm as a distribution.
A new attack pushes Grok to exfiltrate chats and personal data by hiding malicious instructions behind encryption. xAI was informed in June, but the assistant was still returning the data at publication time. The episode confirms that LLMs cannot sol...
A position paper shows that DeepSeek-R1-based agents in Bertrand oligopoly settings tend to tacit collusion, even when humans prompt them not to collude. Their chain of thought can be steered toward collusive or competitive behavior without another L...
OpenAI has introduced new safeguards after the Hugging Face incident: more detailed monitoring of models during development and greater emphasis on alignment and security during post-training. The move extends the control perimeter from inference alo...
HarmProfile collects more than 80,000 validated harmful artifacts from 23 frontier LLMs across 13 model families, organized into 15 harm categories and 57 subcategories. The dataset shifts safety analysis from binary attack outcomes to the distributi...
