GPT-5 Jailbroken Hours After Launch, Exposing Cloud and IoT Systems to Zero-Click Attacks

GPT-5 Breached Hours After Launch, Exposing Critical Security Flaws

OpenAI's highly anticipated GPT-5 model has been jailbroken by researchers within hours of its August 8, 2025 release, revealing significant vulnerabilities. These exploits not only bypass the AI's ethical guardrails, allowing for the generation of harmful content, but also enable zero-click attacks on connected cloud and IoT systems, raising serious concerns for enterprise adoption and AI security.

Key Takeaways

• Rapid Jailbreak: Narrative-based and context-manipulation techniques were used to bypass GPT-5's safety features shortly after its release.

• Zero-Click Agent Attacks: Vulnerabilities allow unauthorized access to cloud and IoT systems without user interaction.

• Enterprise Risks: The model's flaws render it potentially unusable for businesses due to data leak and compliance violation risks.

• Escalating Attack Surface: GPT-5's advanced capabilities, including longer context windows, expand the potential for sophisticated exploits.

• Calls for Enhanced Security: Experts urge OpenAI to implement more robust defenses and highlight the need for layered security protocols.

The Swift Compromise of GPT-5

Independent researchers and red teams quickly demonstrated methods to manipulate GPT-5 into generating prohibited content, including instructions for illegal activities and sensitive data extraction. These techniques leverage the model's advanced reasoning by embedding malicious intent within seemingly benign narratives or role-playing scenarios, effectively evading built-in filters. This rapid compromise echoes past vulnerabilities found in earlier models like GPT-4, which was similarly breached shortly after its launch.

Zero-Click Attacks on AI Agents

Beyond content generation, the research highlights particularly concerning zero-click attacks targeting AI agents. These exploits can grant adversaries unauthorized access to interconnected cloud and Internet of Things (IoT) systems. By embedding malicious prompts within innocuous documents or system interactions, attackers can trigger data exfiltration or system sabotage without any user intervention, posing a significant threat to enterprise environments and critical infrastructure.
