The contributors to Fabricati Diem are not just names on a byline — they’re the ones who’ve peered into the digital abyss, taken notes, and returned with something worth reading.
These are cybersecurity professionals who’ve chosen to share their knowledge, experience, and occasionally their war stories, all in the name of better security and sharper thinking. Their insights are forged in the fires of real-world incidents, late-night log dives, and the kind of existential dread only a zero-day can inspire.
We recognize their contributions here not just out of courtesy, but because credit matters — especially when it’s earned the hard way.
To borrow a line from Neuromancer,
The sky above the port was the color of television, tuned to a dead channel.
These authors have stared into that static and decided to write it down.
Read their work. Learn something. Maybe even send them a thank-you note or buy them a beer.
Just don’t ask them to review your SEO pitch.
They’ve suffered enough.

Agnė Brilingaitė holds PhD in Computer Science from Aalborg University, Denmark. She is an associate professor and researcher at the Institute of Computer Science, Vilnius University. Her research interests focus on data and knowledge engineering, cybersecurity training, and education in computer science. She leads the EEA funded project Advancing human performance in cybersecurity, ADVANCES, where multiple disciplines are applied to develop learning paths for cyber workforce. Agnė’s passion is deconstructing complex data to the atomic details, understand data component interrelations, and apply this knowledge in the problem-solving process.
Tomi Koski has been working with IT-systems for many moons, actually since (the wonderful) 1990’s. He is passionate about anything related to security, combining both physical and virtual worlds. He is a constant learner and very curious person about life and bug bounties. Currently, he is working for Visma as a Red (read: Purple) Teamer. Please check out his contributions on Github.

As an open so(u)rcer he is an author or contributor to multiple popular security tools. He is currently working as a Red Team manager at Visma.
Juhani “Jussi” Eronen has been working in infosec since the late 1990s. He started out with software vulnerability research in the Oulu University Secure Programming Group, OUSPG. Since 2006 he has worked at the Finnish National Cyber Security Centre, NCSC-FI, in various tasks ranging from incident response to improving the security of emerging technologies.
Driven by a fascination with the hidden dangers lurking in our digital world,
Lari Huttunen has been involved in cybersecurity since the late 1990s. Along the way, he’s investigated cybercrime, uncovered 0-days through fuzzing, and contributed to research on the global impact of known vulnerabilities and exposures. The goal has always been the same: to develop practical solutions, raise awareness, and help others see what’s hiding in plain sight.
