This is my first time ever when sharing a revelation on LI. Over the past two years, I’ve been consistently investing in my cybersecurity knowledge - combining structured training with hands-on labs, tools, and CTF challenges. Since 2023, I’ve participated in numerous online cybersecurity trainings made by amazing team from Securitum sekurak, known for their deep-dive, technically focused content. This includes multiple standalone trainings on topics such as: - OSINT tools and techniques, - SIEM #Wazuh – architecture, setup, and alerting, - Using AI tools (ChatGPT, Microsoft Copilot and many others) in security/tech environments, - Automation and scripting in Python for security workflows, - Vulnerability discovery & exploitation; Ongoing participation in the sekurak.academy: - 2023 edition (completed), - 2024 edition (completed), - 2025 edition (2nd semester currently in progress). sekurak.academy offers a broad range of advanced topics, from secure coding and protocol analysis to web app vulnerabilities, threat detection, malware behavior, and more. Along the way, I also tackled various CTF-style tasks provided during the trainings — including challenges in steganography, SQL injection, XXE, XSS, and cipher cracking. Solving them was both mind-bending and incredibly satisfying. Big thanks to Tomek Turba, Michal Sajdak and others for giving such a fantastic opportunity to expand technical skills. #Cybersecurity #Sekurak #Securitum #SekurakAcademy #CTF #SIEM #Wazuh #Python #OSINT #MicrosoftCopilot #Steganography #XSS #XXE #securitytraining #ITsecurity
