Hi all! My name is Cara, and I am a native English speaker from America living in Prague. This a meet up for t**hose learning English as a second language** and want the **opportunity to practice**. It will be a fun and relaxed setting where we will play games to **promote English conversations** or have some kind of activity. This club will meet **every other (two Mondays each month) Monday evening.** The goal is for each person to walk away having learned new English words and have more confidence when speaking in English. Please, bring some money if you want to purchase a coffee from Evento. **This event is sponsored by a church.** The church that sponsors this English meet up is **Církev bratrská, Bohnice** [https://www.cbbohnice.cz](https://www.cbbohnice.cz/) . We want to live lives that are reflective of Jesus. Like Jesus we want to help others in meeting a practical need, in this case that would be speaking in English. At the end of the English club, we will extend an invite to anyone who is interested in exploring faith, wants to know more about Jesus, or wants to meet up to read from the Bible. However, we will never trick you into attending and will always be honest about the content of our meetings. *You do not have to attend religious events to be a part of English Club.*

It's open gaming night again! Come alone (or with friends) and meet some new people to game with. Just look for the 'Open Gaming' table(s) and feel free to sit in. We'll keep the games pretty light, so if you don't know many games, don't feel intimidated. Instruction is always available. (70,- gaming fee still applies)

Our monthly PHP meetup. A virtual shindig courtesy of Zoom. Check back here for the details around 6:15 pm

What does a trojan look like when it has over 900k+ combined installs and a Forbes write-up? Exactly like a legitimate Chrome extension. This session presents a technical dissection of two Chrome extensions, each with over one million active installations — that functioned as trojans in production environments, evading detection while operating through entirely legitimate browser APIs. These were not obscure tools. They were widely trusted, actively recommended, and covered by mainstream press before their malicious behavior was fully understood. We will walk through the actual source code of both extensions, showing precisely how the malicious functionality was constructed, concealed, and executed at scale. This analysis anchors a broader examination of how modern compromises actually succeed. Drawing on aggregated real-world incident data, we identify the technique categories currently delivering the highest adversary return, and why they keep working. Spoiler: it's rarely a zero-day. It's trust. The Chrome extension deep-dive will cover: * Line-by-line source analysis of how malicious functionality was embedded within working, useful software * Which browser permission scopes were abused, and why a million users — and their IT teams — didn't see it coming * The behavioral and structural indicators that distinguish a trojan extension from a legitimate one, and how to operationalize detection around them This session closes with a practical defensive prioritization framework built around observed attacker behavior: which mitigations are measurably reducing risk in production environments, which are consuming budget without impact, and a scoring methodology your team and leadership can apply immediately. **Source material:** Primary analysis of extension source code, corroborated by reporting from Forbes and other established outlets. **What this is not:** A vendor pitch, a speculative threat narrative, or a surface-level breach retrospective. **Who should attend:** Security architects, AppSec and cloud security practitioners, blue team leads, threat hunters, browser security practitioners, and security leaders responsible for prioritizing risk and investment decisions.

It feels like we just saw each other 🤷. Join members of the local design and UX community for our monthly breakfast. For May we’re stopping in for Rooh’s popup breakfast/cafe concept. You know someone is getting the lobster yuzu croissant, and that’s not even the prettiest thing on the menu!.
