I really like those formats as I feel free to roam about, and I believe everyone can learn from each other. I especially appreciate when folks show consideration for each other’s needs. Whenever I'm not busy posing for various photo shoots to represent the Open Security Conference, I'm enjoying myself capturing flags with like-minded folks. Come find me at the Open Security Conference! My Tags: #SecureAllTheThings, #PurpleTeam, #CTF, #SecurityIsFun

🚀 Every year, we challenge ourselves to raise the bar. A conference isn’t defined only by its talks, workshops, or Capture The Flag. It’s also about creating an identity that people remember. Today, we’re excited to share the visual direction for BSides Bratislava 2027. 🛡️ Guardians of the Future This year’s theme represents those who stand at the front line of cybersecurity—professionals, researchers, students, defenders, and the community working together to protect tomorrow’s digital world. This is only the beginning. We’re incredibly excited for what’s ahead, and we can’t wait to welcome you to BSides Bratislava 2027. The future isn’t something we wait for. It’s something we protect. #BSidesBratislava #BSidesBA #CyberSecurity #InformationSecurity #BlueTeam #RedTeam #CTF #Community #CyberDefense #Bratislava #Slovakia #GuardiansOfTheFuture #Infosec #SecurityCommunity #BSidesBratislava2027

This is the best success story a CTF organiser can hope for! StarPWN CTF debuted last year at the DEF CON Aerospace Village. At VisionSpace, we designed the challenges around real-world space systems actively used in the industry. We intentionally reused vulnerabilities we had previously discovered in those systems and introduced a few new ones, giving teams multiple paths to compromise them.
