Prompt Injection Attacks
+ FollowPrompt injection attacks use malicious instructions to manipulate large language models or AI agents into disregarding their original rules, exposing data or performing unauthorized actions. Recent cases have expanded beyond text prompts to images, workflows, development tools, AI browsers and agent marketplaces. The resulting risks include sandbox escapes, credential theft and malware implantation. OpenAI, Microsoft and cybersecurity companies have rolled out patches, protective modes and red-team evaluations in response. As AI agents gain access to more tools and system privileges, the impact of such attacks could extend beyond the model layer to corporate data, accounts and CI/CD environments, making the threat an important area to watch.
