Spotlight on BSides Vilnius 2026: Meet our speakers!

Our speaker lineup is officially complete, and we think this last addition brings a really important conversation to the event. Joining us for the final talk announcement is Rūta Apeikytė with “Cybersecurity Theatre at the NATO Summit 2023.”

🎙 The talk

“Preparing for a major event is like preparing for a theatre performance, where the team plans every detail - from coordination to rehearsals. Even with careful preparation, unexpected challenges can still arise. This was the case for NCSC Lithuania during the NATO Summit 2023. Although the team was ready for cyberattacks, they still faced an unanticipated threat - hybrid attacks. The NATO Summit 2023 case demonstrates how lessons learned today can strengthen our readiness for high‑stakes events in the future.”

👤 About the speaker

Rūta Apeikytė is Head of Partnerships and Competence Development at the National Cyber Security Center, working at the intersection of strategic communication and cyber security. She has experience operating in challenging geopolitical contexts and was part of team efforts addressing hybrid incidents during the NATO Summit 2023. Rūta focuses on collaboration, learning, and strengthening practical cyber resilience through partnerships and shared expertise.

Join us to see what happens when the performance ends and reality takes over. See you there!

Spotlight on BSides Vilnius 2026: Meet our speakers!

We’re excited to introduce our next speakers joining us this year. Say hello to Blessen Thomas and Wojciech Poparda, who will be presenting “Don’t Trip the Breaker: A Practitioner's Guide to Safe Power Grid Pentesting.”

🎙 The talk

“Pentesting a power grid is a high-stakes game where "move fast and break things" is a recipe for disaster. This talk breaks down on a regional grid, providing a transparent look at a safety-first methodology that balances deep technical discovery with 100% operational uptime.

We’ll dive into the architecture, starting with how to map environments using digital twins and mirrored test benches before a single packet is sent. The core of the session focuses on the data: leveraging passive traffic analysis and protocol-specific inspection to identify firmware flaws and clear-text command paths without ever touching a live PLC.

The narrative follows a lateral movement scenario, testing if guest or corporate Wi-Fi can pivot into the heart of the control network. We’ll wrap up with a blueprint for conducting OT assessments that satisfy both security auditors and plant engineers—revealing the "crown jewels" of an ICS network without risking a blackout.”

👤 About the speakers

Blessen Thomas is an Independent Security Researcher with more than 13 years of experience in Red Teaming, offensive security, and testing specialized environments like OT, IoT, mainframes and telecoms. He holds a wide array of certifications, including SANS GPEN, CRTO, and OSCP, and is recognized in multiple corporate Halls of Fame for responsible disclosure. An active open-source contributor to projects like the OWASP Mobile Testing Guide, his research has been accepted at global conferences including Hack in the Box, CanSecWest, and numerous BSides events. He spends his leisure time playing drumkit and percussion.

Wojciech Poparda is a cybersecurity consultant who helps organizations proactively defend their digital infrastructure by thinking like an adversary. He specializes in building resilient security architectures that bridge complex attack vectors with enterprise defense, focusing closely on Cloud Security and Identity & Access Management (IAM). He holds elite credentials including OSCP, CRTE, and CISSP, and applies the same dedication to solving complex technical challenges as he does to competing in the IRONMAN European and World Championships.

Join us to learn how to audit critical infrastructure safely without risking a blackout. See you there!

Spotlight on BSides Vilnius 2026: Workshop!

For our final workshop reveal, we are thrilled to introduce Andrea Brosio leading “AI Red Teaming by TryHackMe”.

🛠 The workshop

“Language models are being dropped into production pipelines, security tools, and autonomous agents faster than anyone can audit them, and the attack surface is wide open. This workshop takes you through three layers of offensive AI attack, hands-on. You will learn how to hijack model behavior through prompt injection, turn AI pentesting agents against themselves, and surgically disable safety alignment by ablating specific layers inside the model.Every section includes a live demo and exercises you run yourself. By the end you will understand not just how these attacks work, but why they work, and what that means for any system that trusts a language model.”

🎙 About the instructor

Andrea Brosio is an Offensive Security Engineer with 6+ years of experience in red teaming: malware development, EDR evasion techniques and building offensive tooling. Currently building AI driven pipelines for automated vulnerability discovery and exploitation.

Time to turn offensive AI against itself. Pack your laptop and let's go!

‼️P.S. Registration to the workshops opens tomorrow at 10:00 GMT+3! Make sure to secure your spot here: https://registration.bsidesvilnius.lt/
