Prompt Injection Poses Major AI Security Risk, but Mass Exploits Remain Constrained

Prompt injection has become the top threat in AI security because large language models cannot reliably distinguish legitimate user instructions from malicious commands hidden in third-party content. This vulnerability allows attackers to surreptitiously inject commands that the LLM will follow.

Developers rely on guardrails to mitigate damage rather than fix the root cause. Currently, most prompt injections are 'push' attacks targeting individual victims, limiting their ability to achieve large-scale exploits.
