Owen Pierce

Security Engineer: cloud, DevSecOps, and offensive security.

LinkedIn HTB CPTS and CDSA

Terminal session. $ whoami -> owen, security engineer at Ally. $ cat ~/.history -> sre: ran production AWS with Terraform and CI/CD; soc: worked the queue as the team's AWS SME; sec eng: cloud and pipeline security, internal offensive testing. $ ls ~/focus -> ai-security, cloud-security, devsecops, infrastructure-as-code, pipeline-security, offsec.

I sit on a team with threat hunting, detection engineering, and automation engineering. My lane is cloud and DevSecOps security: hardening AWS and CI/CD, writing the occasional detection, and assessing our own platforms the way an attacker would.

Things I've built

Project What it does
reaper
TypeScript
JavaScript/TypeScript malware deobfuscation and triage. Static dead-code and obfuscation analysis plus a hardened Docker sandbox for dynamic runs.
wsmancer
Go
PSRP-native WinRM shell for offensive Windows work. NTLM/Kerberos message sealing, typed JSON output, sessions that survive dropped connections.
rummage
Go
TUI file picker and fuzzy finder library for Go, built on Bubble Tea.
dotfiles
Go
Idempotent, reversible workstation configurator for Linux and macOS, with dry-run and drift detection.
htb-hosts
Python
Sudo-free /etc/hosts manager for Hack The Box, as a CLI and a zero-dependency MCP server.

Behind the curtain

Most of my infrastructure work lives in a private GitLab: about 100 Ansible roles and Terraform across 25+ repos running a segmented homelab.

Terraform Ansible Vault Teleport Headscale Suricata Proxmox VyOS

  • Zero standing privilege: Vault with default-deny, short-lived scoped tokens so automation and AI agents never hold admin credentials
  • 15 segmented VLANs behind Suricata inline IPS; Headscale, Teleport (WebAuthn), and Authelia SSO for access
  • An Active Directory attack range built from a Packer golden image, with Terraform and Ansible injecting repeatable misconfigurations
  • Routers, DNS/DHCP, hypervisors, and services converge from Ansible and Terraform in CI
