Problem I see is people are confusing code reasoning with hacker intuition. To understand where LLMs fit in AppSec vuln research, firstly we need to categorize the cognitive load of vulnerabilities: 1. Pattern Matching Tracing user input for XSS, IDORs, Injections etc. If your…

When the POC comes out, it’ll be a humbling moment for LLMs and how we use them. What’s circulating is extremely naive and incorrect. Experienced engineers are sharing plausible-sounding hallucinations from frontier models. Reminder to bump React, Next & frameworks.

This. Alert & CVE fatigue are real. Perpetually growing backlogs of bugs means no one gives a shit anymore. We need clear writeups that consider exploitability, and include a patch. If you can automate finding bugs, you can automate submitting fixes.

Denial of Attention is a real security threat in the AI era and I am surprised we don't hear about this more
