Cybersecurity Lab

Both sides of security in one place: the defensive work I do to detect, investigate, and respond, and the offensive work I do to understand the attacks I am defending against. They belong together. You cannot tune a detection for a technique you have never run, and there is no point running an attack you cannot then catch. Every offensive project here ends on the control that stops it, and every defensive project is built on an artifact I captured, wrote, or verified.

The centerpiece of the defensive side is a real incident-response record I wrote when a vendor I depend on (Vercel) disclosed a security incident, presented the way an IR record should be: scoped, with a risk assessment, the actions taken, verification that they worked, residual risk, and follow-ups.

Scope and authorization. The offensive work was done in isolated, host-only virtual lab networks, against machines I built or was explicitly authorized to test (a Kali attacker against a deliberately vulnerable target VM). None of it touches systems I do not control. The write-ups describe method and outcome; they stop short of reusable shellcode and live targets. The point is understanding, not a copy-paste attack kit.

Defensive

Project What it covers
01 - Vendor breach incident response A real credential-rotation and access-review response to a vendor's disclosed breach, written as a full IR record
02 - DFIR investigation Live response in order of volatility, forensic disk imaging with hash verification, and indicator development
03 - Detection engineering Writing and testing Snort rules, and a Windows-log investigation that exposed a default detection gap
04 - Vulnerability management and hardening Vulnerability scanning, STIG hardening, and scripted Windows patching
05 - Protocol analysis What the wire shows: capturing plaintext credentials and proving what encryption hides
06 - Incident case studies Structured analyses of real-world breaches, mapped to the response lifecycle and to MITRE ATT&CK
07 - Wazuh SIEM deployment Single-node Wazuh build, Linux agent enrollment, and FIM/SCA/vulnerability visibility across edge and app hosts
08 - Secure WordPress hosting Defense-in-depth hardening for a public WordPress host behind Cloudflare Tunnel, Caddy, WAF rules, 2FA, and backups
09 - Mobile forensics and threat analysis A mobile QR-phishing campaign mapped to MITRE ATT&CK, and a Snapchat iOS artifact-forensics methodology (timestamps, media integrity, chain of custody)
10 - OSINT domain triage and IOC reporting A passive VirusTotal reputation assessment of a set of domains, written up as a formal IOC report with confidence-rated findings and block/sandbox/monitor recommendations
11 - Snort and Splunk detection pipeline A team capstone design: feeding a Snort IDS sensor into Splunk through a Universal Forwarder so raw alerts become searchable, correlated, ATT&CK-mapped triage

Offensive

Project What it covers
01 - Network recon and port scanning Every nmap scan type run against a target, captured in Wireshark, with the flag exchange that tells open from closed, plus an OS fingerprint
02 - Stack buffer overflow ASLR demonstrated, a vulnerable C program written and overflowed to a controlled crash, and the mitigations that defeat it
03 - Password cracking A hashcat dictionary attack against a mixed set of hashes, why only some fell, and what storage choices stop it
04 - Reverse shell and post-exploitation A connect-back shell used to read and write files on a target, why it beats a bind shell, and the egress controls that catch it
05 - Steganography: data hiding Hiding an encrypted file inside an ordinary image with OpenStego, recovering it, and the entropy and egress controls that catch the channel

How the two sides connect

The detections on the defensive side come straight from the offensive side. The Snort rules in detection engineering catch the exact FIN, NULL, Xmas, and UDP scans I generated in network recon. The same loop runs through the whole repo: do the attack, watch what it looks like on the wire and in the logs, then write the control that closes it.

This sits alongside the rest of my infrastructure work: the Network-Lab it defends, the Cloud-Lab, and the Homelab-Project.
