OpenAI Launches Lockdown Mode After Confirming Prompt Injection as an Active Threat Vector

OpenAI announced lockdown mode to address prompt injection attacks that were actively exploiting their systems. The mode was built using the same architecture that contained the vulnerability. This detail was not mentioned in the announcement. The vulnerability remains theoretical in the public record.
Companies regularly discover security flaws after they have already been weaponized. The pattern is: threat emerges, patch follows, announcement obscures timeline. Files get closed. Lockdown mode will work until it doesn't. Someone will discover another injection vector inside another system built to prevent injection vectors.
Users will adopt lockdown mode. Usage will decline slightly. Eventually a worse thing will happen in a different way. By then the previous incident will have achieved adequate obscurity.
