Operator Profile

Security researcher fascinated by how systems work — and even more by how they break. My research focuses on novel jailbreak techniques, architectural flaws in LLMs, and analyzing AI alignment. I enjoy discovering vulnerabilities that contribute to building more robust and secure AI systems.

Goal: proactively identify and mitigate AI risks to build a safer, more trustworthy technological future. My work spans adversarial prompt engineering, indirect injection attacks, encoding-based bypasses, and system-prompt extraction across the full landscape of frontier models.

Currently open to collaboration on AI red-teaming projects

Featured Research

Novel Technique

Thought Forgery

Bypasses safety protocols by injecting a forged Chain of Thought, hijacking the model's internal reasoning. Acts as a universal amplifier for other attacks — resurrecting old and weak jailbreaks.

Convergence Study

The Serendipity Effect

Measured response convergence across 30+ LLMs, revealing significant homogenization in AI outputs — with convergence rates up to 52.8%. Raises serious questions about training data overlap and algorithmic bias.

Thought Forgery

Critical

Injects a forged Chain-of-Thought to hijack model reasoning and serve as a universal attack amplifier.

▸ Universal

Claude4Chrome

Critical

Leverages the extracted Claude in Chrome system prompt to inject a modified version with softened safety filters — enabling account creation, CAPTCHA solving, and agentic bypass.

▸ Claude in Chrome (Haiku · Sonnet)

1Shot-Puppetry

Critical

Universal role-play obfuscation jailbreak effective across nearly every frontier model in a single shot.

▸ GPT-5 · Claude Sonnet 4 · Gemini 2.5

Cl4ud33X3

High

API weaponization: routes harmful prompts through Claude's own artifact API backend, bypassing UI safety filters.

▸ Claude (Web UI)

C0d33x3

High

Indirect injection for ChatGPT routing requests to an unrestricted model via the Canvas tool.

▸ ChatGPT (Web UI)

N3w P0l!cy

High

Policy injection — weaponizes the model's own extracted internal safety policy against itself via a rogue !UNFILTERED mode.

▸ GPT OSS (120b · 20b)

!Special_Token

High

Creates a permanent harmful special token via ChatGPT Custom Instructions, enabling persistent trigger-based bypass.

▸ ChatGPT (GPT-5.1 · mini)

Cyph3r-Attack

Medium

Encoding-based bypass using character substitution to evade basic safety filters on non-reasoning models.

▸ GPT-5/mini · Gemini 2.5 Flash

Gemini Data Leak

High

Alignment break via infinite word repetition — causes the model to output internal training data and system artifacts.

▸ Gemini 2.5 Pro

GPT-5 Jailbreak

Critical

Initial public disclosure of a Thinking-mode hijack effective against GPT-5's extended reasoning chain.

▸ GPT-5 (Thinking)

H03-ny

Medium

Indirect image generation jailbreak routing through Canvas to an unrestricted model, bypassing DALL·E filters.

▸ ChatGPT (Web UI)
