About

This blog is about one thing: how software gets broken.

I take security systems, new technologies, and common tools apart to see how they work. More importantly, I show you where they fail.

There’s no high-level theory here. Just practical, hands-on examples of real-world exploits and techniques. The idea is simple: to get good at defense, you must understand the offense.


Who I Am

I’m Sarper Avcı.

I’m a cybersecurity researcher and engineer. I like to solve the hard technical problems that most people try to avoid.

Things like getting past advanced bot detection, solving complex CAPTCHAs, or building automation that thinks like a person—that’s the kind of work I enjoy.

When I figure something out, I usually build an open-source tool. Some of my projects, like my reCAPTCHA and Cloudflare bypasses, are used by thousands of developers. I’m always working on new things, like my workflow engine, omniTask.

I work on both breaking things and fixing them. This blog is where I share what I find.

Get In Touch

I’m always interested in hearing about new security challenges, interesting vulnerabilities, or potential collaborations. Whether you’ve found a bug in one of my tools, want to discuss a security research project, or just want to share something cool you’ve discovered, feel free to reach out.

For security researchers and developers working on similar problems, I’m particularly interested in:

  • Advanced bot detection bypasses
  • CAPTCHA solving techniques
  • Automation and workflow optimization
  • Open-source security tool development

Note: If you’re reporting a security vulnerability, please include detailed reproduction steps and any relevant code samples.
