jakub buczak

I am a dedicated cybersecurity professional with a strong background in threat hunting, threat intelligence, and penetration testing. My journey in cybersecurity began with an internship at EY GDS Wrocław, where I quickly transitioned into more responsible roles, conducting threat hunting and preparing detailed reports on security alerts. My ability to identify security vulnerabilities and conduct original threat research has been instrumental in my career growth.

During a major ransomware incident at a Fortune 500 company, I conducted in-depth research on cybercrime forums, identifying Tactics, Techniques, and Procedures (TTPs) and assessing the attackers' technical skill level. This work was particularly challenging as the group was new and unreported, with no existing Indicators of Compromise (IOCs) or reports available. My findings were crucial in helping the company understand and mitigate the threat.

In addition to my professional experience, I have a solid foundation in programming and automation, having used Python to automate data entry tasks and write proof-of-concept exploits. I also have experience with neural networks using PyTorch and have explored the application of Large Language Models (LLMs) in solving complex problems. My analytical and critical thinking skills, combined with my ENTJ personality type, drive me to continuously learn and grow in the ever-evolving field of cybersecurity.
