OpenAI's GPT-4o is a version of the GPT-4 family deployed on OpenAI's platform with advanced capabilities (including multimodal processing in supported contexts).
OpenAI's GPT-4o is a technology platform tracked across 2 threat clusters and 1 intelligence report mention on ThreatCluster. First observed November 14, 2025; most recent activity November 14, 2025.
OpenAI's GPT-4o is a version of the GPT-4 family deployed on OpenAI's platform with advanced capabilities (including multimodal processing in supported contexts). A recent report details a hole in its AI guardrails that can be exploited by crafting input strings such as =coffee to bypass safety controls, illustrating a prompt-injection risk. This matters in cybersecurity because it shows how attackers could subvert safety mechanisms in AI-enabled workflows and potentially obtain unsafe outputs or access restricted information.
Security researchers from HiddenLayer have developed a new attack method called EchoGram, which targets the guardrails of large language models (LLMs). By using specific phrases like '=coffee', attackers can bypass…
Researchers from HiddenLayer have identified a new attack technique called EchoGram that can bypass AI guardrails designed to filter harmful input in large language models (LLMs). This technique allows users to…
