I'm Mikael Nurminen, known online as mixutin / 0x11a — a cybersecurity researcher and CTF player from Finland.
I take systems apart to understand them, then build something useful with what I learn. My work spans cryptography, reverse engineering, native tools and game preservation. I care about keeping software and overlooked media alive after the original services disappear.
I compete with THEM?!, focusing on cryptography and reverse engineering: understanding the implementation, questioning its assumptions and turning a difficult challenge into an explanation that holds up.

Self-reported September 2026 ranking snapshot, not a live leaderboard. The linked CryptoHack profile is the place to check the current position.
A selection of my public repositories. Experiments are labelled as experiments; each repository has the latest implementation status.
| Project | What I'm building | Stack / stage |
|---|---|---|
| Vibrix | An independent Rust operating system, working toward a persistent, portable USB-first system. Website ↗ | Rust · x86-64 · UEFI Experimental OS |
| Lumina | A Steam-free Linux launcher project for the official HoYoPlay launcher and Zenless Zone Zero, built around UMU/Proton. Website ↗ | Rust · Tauri · Linux Pre-alpha |
| Mallow | Native Apple Silicon tooling working toward Windows compatibility, starting with Wine installation and integrity checks. Website ↗ | Swift · macOS · Wine Development preview |
| Dauntless Revived | Game preservation through reverse engineering and a self-hosted backend. A modified fork of Undaunted. Docs ↗ | TypeScript · Backend Community revival |
| Jake / JKI | A voice-controlled Linux desktop companion for Codex, combining local speech recognition, spoken replies and a GTK interface. | Python · GTK 4 Desktop tooling |
Development notes: Vibrix's persistent USB system is a goal, not a finished release. Lumina is pre-alpha. Mallow's preview installs and verifies Wine; it does not run Windows programs yet. See the linked repositories before trying development builds.
Upstream credit: Dauntless Revived builds on Undaunted by gwog (Gregory Morford) and contributors, under AGPL-3.0. It is an unofficial fan project; no game files are distributed by the repository.

🇫🇮 Suomeksi
Olen suomalainen tietoturvan tutkija ja CTF-kilpailija. Keskityn kryptografiaan, takaisinmallinnukseen ja avoimen lähdekoodin ohjelmistoihin. Kilpailen THEM?!-tiimissä.
CryptoHack: #1 Globally ja #1 In Finland. Sijoitus on itse ilmoittamani syyskuun 2026 tilanne, ei reaaliaikainen tulostaulu. Ajantasainen profiili →
Julkisia projektejani ovat Vibrix, Lumina, Mallow, Dauntless Revived ja Jake / JKI. Niissä yhdistyvät käyttöjärjestelmät, työpöytätyökalut, pelien säilyttäminen ja tekoälyavusteinen kehitys. Projektitaulukon linkeistä löydät lähdekoodin ja kehitysvaiheen. Vibrixin pysyvä USB-järjestelmä on vielä tavoite, Lumina on esialfa ja Mallow ei vielä suorita Windows-ohjelmia. Dauntless Revived perustuu gwogin ja muiden tekijöiden Undauntediin (AGPL-3.0).
