Joey Escamilla

Passionate security researcher based in Seattle. I build secure software and break insecure software. I write security tools in Go, Python, and C++ and compete in CTFs.

I'm looking for work! Let's connect on LinkedIn.

Employment

  • Tech The Right Way: Fullstack Engineer (July 2025 - Present). Built a browser-based SIP softphone and operator switchboard using SIP.js, WebRTC, Next.js, and TypeScript. I also do code reviews with Semgrep and built infrastructure automation in Go using the Proxmox API and Ansible.

Organizations & Events

  • Port 22 SSH Hackerspace: Board member. Cybersecurity non-profit in Tacoma, WA.
  • HushCon - Seattle / NYC: On the CFP board and handling sponsorships since 2025. Invite-only cybersecurity conference with hush rules on all talks.
  • Seattle Locksport: I've been going to the Seattle locksport meetup since 2025.
  • DC253: I've been going to DC253 since 2024. DEFCON group in Tacoma, WA.
  • BSides Seattle: Good local cybersecurity conference. I've competed in the Attack/Defend CTF here.

Security Tools

  • lazyRecon: Recon automation tool in Go. Subdomain enumeration, alive checks, technology detection. My go-to for starting bug bounty recon.
  • snoops: Packet analyzer with a TUI in Go. For when Wireshark is overkill.
  • stepper: WIP tool to grab CTF flags from binary registers. C++.
  • HookTesting: Windows hooking research. Inline hooks and registry hooking in C++.
  • superblue: Turning a Spotify CarThing into a handheld Bluetooth hacking tool. WIP.
  • LeViBot: Bot I wrote in JavaScript.
  • AvYara: YARA rule scanner in C++. Scans and classifies files.

Writeups

  • Hyde-street-writeup: Writeup for the Hack-A-Sat 4 Quals "Hyde Street" challenge. This was a signals/space challenge.
  • gonna-lift-em-all: HTB Crypto CTF writeup. Crypto challenge from the 2022 Cyber Apocalypse event.

Competition Participation

I mostly focus on web and misc challenges in CTFs.

  • Spokane Cyber Cup 2026: I was a coach for this one, helped people out when they got stuck on challenges.
  • The Diana Initiative CTF 2025: Got 2nd place even though I started a few hours late.
  • Trace Labs Search Party 2025: OSINT CTF focused on finding missing persons.
  • BSides Seattle Attack/Defend CTF 2024: 2nd place. Attack/defend format where you're exploiting other teams while defending your own boxes.
  • Hack-A-Sat 4 Qualifiers 2023: 20th out of 381 teams. Satellite hacking CTF run by the US Air Force and Space Force. Challenges involve RF, signals, and space systems.
  • Hack The Box Cyber Apocalypse 2023: Top 5%. Mostly did web and misc challenges.
  • SkillsUSA CyberSecurity: Qualified for nationals.

Conference Speaking

  • HushCon West - Seattle, WA (2024): Talked about polyglot file techniques to 300+ people. Polyglots are files that are valid as multiple file formats at the same time, which gets weird fast from a security perspective. Slides are on GitHub. I'd love to do more talks in the future.

Certifications

  • CompTIA Security+

Other Interests

  • openpilot: Fork of comma.ai's openpilot. Car hacking is fun.
