AWS meetups are back in town! This chapter is the 1st one this year and dedicated to **S3.** But we look on the storage from completely different angles: **From Developer's to Penetration and Security perspective.** More info soon, and the meantime we reveal topics, and... 🗓 **Save the Date**: Mark your calendar 🍕 + 🍺 = Let's gather around pizza and beer at **Hevre** or Watch the stream on [YouTube (Link)](https://youtube.com/live/Tx7lmDVTVKo) Hosted by: **Maciej Lelusz**, AWS Hero AWS Community Builders: **Maria Kmita & Pawel Kusinski** 🎤 **Speakers**: 〰️ *„*"Optimizing S3: A Million-Dollar FinOps Journey" **Avihay Tsayeg,** Senior Staff DevOps Engineer, Cloudinary 〰️ *„UnS3cure - Buckets full of holes"* **Paweł Kusiński,** Penetration Tester and Security Researcher 💡 Details about Speakers & Talks💡 **Avihay Tsayeg:** joined Cloudinary five years ago and is a key member of the Infrastructure group, where he leads the FinOps domain. With over 20 years of experience in software development, specializing in the DevOps–FinOps intersection, Avihay brings deep expertise in cloud cost optimization. ☞ will speak about: In his talk, he will share actionable strategies for mastering resource cost management within AWS S3. **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 speak 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?

We’re heading back to Scene75 on Friday, March 27 for a high-energy night of laser tag, mini golf, go-karts, arcade games, and whatever chaos we decide to get into. We’ve done this one before and it was a blast — great turnout, tons of laughs, and just the right mix of competition and hanging out. If you missed it last time, this is your shot. 🎯 What to Expect: Laser tag battles Mini golf challenges Go-karts (for those who need speed) Arcade games & game cards You can load however much you’d like onto a game card. Most people will probably be good with $15–$30, but it’s totally up to you. This is a super casual event — show up, jump into whatever looks fun, rotate groups, and hang out. No pressure, no complicated structure. Just a solid Friday night with good people. Also… I haven’t hosted in a bit and I’m making a push to be more active again. If you’ve got ideas for future events you’d love to do, bring them. I’m all ears. Let’s run it back. 🔥
