I built a vulnerable app and spent $1,500 seeing if LLMs could hack it
I spent $1,500 testing if LLMs could exploit my app. Here's what actually happened.
Why it matters
Practical security research on LLM capabilities vs. real-world vulnerability exploitation reveals gaps between hype and actual threat levels—critical intel for teams building defensible AI systems.
