Details about Speakers & Talks

Paweł Kusiński:

Penetration Tester and Security Researcher focused on app and cloud security. His work includes penetration tests and infrastructure audits across a wide range of IT projects. Passionate about knowledge sharing, he leads workshops, gives conference talks, teaches at universities, and is an AWS Community Builder.

Outside of work, he plays CTFs as a member of justCatTheFish and has an unhealthy habit of buying too many Legos - despite having absolutely no space left for them.


will talk about:

Time goes by, AWS keeps adding new security features, and yet year after year we hear about more data leaks and breaches involving S3 buckets. Data spills by the terabyte, companies apologize, and shortly after, the cycle repeats.

How does this keep happening? What is the core problem? How do attackers find their targets? We’ll walk through the most common methods and configuration mistakes - and if time allows, we’ll try to secure everything properly as well! And who knows - maybe we'll uncover a million-dollar leak during the presentation?
