Offensive Security Researcher

Almadhi

Penetration tester & vulnerability researcher · Riyadh

I break the technology millions of people rely on, then help close the gaps before attackers do. Four published CVEs, two of them scoring a perfect CVSS 10.0, the highest severity a vulnerability can reach. My top two reports paid $30,500 and $25,000.

Offensive security, end to end.

I help organizations find their weaknesses before attackers do, from a single overlooked parameter to a full-scope red-team operation.

I'm Aziz, a penetration tester and vulnerability researcher from Harmah, now based in Riyadh, and the founder of Catchify. I find the flaws others miss. My work covers web, API, mobile, and network penetration testing, full red-team engagements, and original research that has produced four NVD-published CVEs.

Two of those are maximum-severity CVSS 10.0 findings in Ubiquiti's UniFi platform, and a third is critical (9.9) in the UID Enterprise Agent. One UniFi Access disclosure earned a $25,000 maximum Ubiquiti bounty via HackerOne. A UniFi OS path traversal earned a $30,500 bounty, my highest so far. All of them are published, patched, and credited by the vendor.

I founded Catchify to bring focused, Saudi-led offensive security to organizations across the Kingdom. On a bounty, an engagement, or a report, I aim for one thing: a clear, prioritized path to closing the gaps that matter.

CVE-2026-34909 Ubiquiti · UniFi OS
CWE-22UnauthCISA KEV$30,500

UniFi OS: Path Traversal

Unauthenticated path traversal in UniFi OS: a network attacker can read and manipulate files on the underlying system to take over a host account. Patched in UniFi OS Server 5.0.8 and the matching UDM / gateway builds; 31 device models were affected. Later added to CISA's Known Exploited Vulnerabilities catalog after confirmed exploitation in the wild. Credited to Abdulaziz Almadhi of Catchify in Ubiquiti's advisory; $30,500 bounty.

UID Enterprise Agent: Command Injection

Improper input validation in the UID Enterprise Agent (< 1.61.4) lets a low-privileged network attacker run arbitrary commands on the host device, effectively remote code execution. Credited to Abdulaziz Almadhi of Catchify in Ubiquiti's advisory.

04·Work

How I work.

The offensive capabilities I bring to every engagement.

01

Bug Hunting

Hunting real, exploitable vulnerabilities across bug bounty programs and live targets, and reporting them so they get fixed.

02

Penetration Testing

Hands-on assessments of networks, APIs, web and mobile apps. Manual testing backed by Burp Suite and Kali, with a methodology I have refined over years of real findings.

03

Red Teaming

Full-scope, adversary-emulation engagements that test detection and response. The question isn't whether a box is patched. It's whether your defenses actually hold.

04

Reports & Insights

Clear, prioritized reporting that explains the real-world risk and the exact steps to fix it. Your team gets a plan, not a pile of noise.
