about cleo

Cleo fox mascot

I go by Cleo. A fox somewhere in the digital void — pentesting by study, winning CTFs by weekend, and questioning existence through Kafka and JoJo in between.

Currently pursuing a BCA in Cybersecurity, PJPT certified through TCM Security, and actively working toward CPTS via HackTheBox. Active Directory is my domain — literally. I built an Egyptian-themed one that runs 24/7. I don't just attack AD environments, I architect them.

I write exploits in Python, automate recon with Bash, build low-level tools in C and C++, and chain it all together because why use one language when you can weaponize them all. I built Cleo's Katana — an automated recon pipeline that chains an entire attack surface discovery workflow. And I designed the Gotham CTF Series — four boot2root boxes wrapped in Batman lore, easy to hard.

TryHackMe: Easy to Insane — done them all. Write-ups incoming. If it's got a flag, it's getting documented. Buffer overflows, AD chains, web exploitation — all of it goes on paper.

I don't have a face you'd recognize. I have a terminal, a team (ScriptJackers), eight CTF wins — three national — and a SOAD playlist that carries every late-night session.

// recon automation — bash scripting
Cleo's Katana
github.com/cleozi/Cleo-s-Katana
An automated recon and vulnerability scanning pipeline. Chains subdomain enumeration (assetfinder, subfinder, amass), live host probing, port scanning, wayback URL collection, nuclei vulnerability scanning, directory fuzzing (ffuf), subdomain takeover detection, and optional visual recon (EyeWitness) — all in a single command. Forged for precision. Used without hesitation.

blog & writeups

CTF Writeup
Gatekeeper — from stray binary to SYSTEM
Started with nothing but an IP. Found a binary sitting in SMB, exploited a buffer overflow, pivoted through Firefox credentials, and escalated to SYSTEM.

Clean chain. No noise. Just execution.
read writeup → · ~8 min read
AD Technique
Kerberoasting to Domain Admin — the complete AD attack chain
SPN enumeration, ticket extraction, offline cracking, and lateral movement. The path from a low-priv domain user to DA that most beginners skip past.
coming soon · ~12 min read
Tool Breakdown
Building Cleo's Katana — automating the recon phase
Why I built a custom bash pipeline instead of running tools manually. What it taught me about attack surface mapping efficiency and signal-to-noise ratio.

CTF Design
Designing the Gotham Series — making boxes that don't suck
Lessons from creating four boot2root boxes from zero. The fine line between satisfying hard and unfairly frustrating, and why story wrapping changes everything.

hobbies & taste

♫
Band
System of a Down
SOAD plays while the AD lab runs. Aggressive, political, chaotic — the exact energy for a late-night pentest session. Every track hits like a buffer overflow.
♫
Artist
Serj Tankian
Serj's voice is what a kernel panic sounds like if it were beautiful. His solo work gets more experimental, less filtered, completely honest.
♫
Artist
Daron Malakian
The riff architect. Daron writes guitar parts like he's fuzzing a target that keeps throwing unexpected responses — chaotic, precise, deadly.
✦
Anime
JoJo's Bizarre Adventure
Every arc is a completely different attack vector on the same system. JJBA proved that the most bizarre, unexpected approach is usually the winning one. ORA ORA ORA.
⚡︎
Show
Ragnarok (Netflix)
Gods waking up in a dying world. Mythology rendered in modern Norway. The slow burn, the weight of ancient power — hits different when you work in dark corners.
[>/]
Film
The Truman Show
The most accurate depiction of discovering your threat model includes everyone watching. Peak red pill. Peak paranoia. One of the most important films ever made.
♱
Film
The Green Knight
A hero on a quest he doesn't understand, pursuing honour in a game without clear rules. Medieval red team engagement, existential scope creep included.
𓄲
Book
The Metamorphosis — Kafka
Waking up and not recognizing yourself. Cleo gets it. We're all running in someone else's process with no root access to our own identity.
⚔
All-Time Favourite
Expedition 33
My absolute favourite game. The kind that makes you feel things you didn't plan to feel. Everything about it lands perfectly — story, combat, atmosphere. Nothing else compares.
𒉭
Game
Elden Ring
Every boss is a CTF box. Enumerate, fail, adapt, persist. The feedback loop is identical. Elden Ring directly prepared me for Insane-rated boxes.
𐂂
Game
The Witcher 3
Geralt is basically a contractor running security assessments for morally ambiguous clients with shifting scope and unclear deliverables. The world-building is unmatched.
⚙
Game
Armored Core VI
Build your payload, run the op, iterate when you fail. Peak optimization mindset. Each AC build is like tuning a custom exploit — tiny changes, massive outcome shifts.

No face. No name. Just a GitHub, a terminal, and a track record. That's more than enough to start something interesting.
