The security research and talks worth your time.

Substack Cybersecurity Weekly Updated Sep 2026

About

tl;dr sec rounds up the security research, conference talks, tools, and writeups worth a practitioner's time, filtering an overwhelming field down to a manageable weekly list. It leans toward application security and offensive research, with links chosen for technical depth rather than headline value.

Each issue groups recommendations by topic (talks, write-ups, tools, and CTF-adjacent material) so readers can jump to what's relevant to their work. It has become a reliable channel for security engineers who want to keep up with the field's fast-moving research output without trawling conference archives themselves.
