**Meetup No. 68 - RedTeamRD** La comunidad RedTeamRD regresa con un meetup donde exploraremos dos superficies de ataque que muchas veces pasan desapercibidas: la infraestructura física que mantiene vivos los datacenters y la lógica detrás del control de acceso en aplicaciones web. Este encuentro nos llevará desde los sistemas HVAC controlados por PLCs hasta la manipulación lógica de endpoints vulnerables. Dos charlas. Dos mundos. Un mismo problema: lo que asumimos seguro, rara vez lo es. **Capa 0: Cuando el Ataque No Busca Datos, Busca Derretir el Hardware** 🎙️ **Fidel Jeldes** La mayoría de las estrategias de ciberseguridad están diseñadas para proteger información: bases de datos, credenciales, propiedad intelectual. Pero ¿qué ocurre cuando el atacante no quiere robar datos, sino interrumpir físicamente la operación? En esta charla exploraremos la “Capa 0”, la infraestructura crítica que mantiene vivos a los datacenters: sistemas HVAC, chillers, distribución eléctrica y sensores ambientales gestionados por PLCs que utilizan protocolos industriales heredados, sin cifrado ni autenticación robusta. Analizaremos cómo la convergencia entre IT y OT ha abierto una superficie de ataque poco visible pero altamente crítica. Veremos cómo un actor malicioso puede pivotar desde la red corporativa hacia la red de gestión ambiental y manipular protocolos como Modbus/TCP o BACnet para alterar lecturas de sensores, provocar sobrecalentamientos o forzar paradas de emergencia. Una sesión que cambia la perspectiva tradicional de la seguridad y nos obliga a pensar más allá de los datos. **Access Control: Cuando la Lógica es Vulnerable** 🎙️ **Bryan Céspedes** Un recorrido práctico por laboratorios de PortSwigger enfocados en vulnerabilidades de control de acceso roto, mostrando cómo la simple observación y el pensamiento lógico son suficientes para acceder a lo que no deberías. Se abordará la manipulación de parámetros de solicitud, el descubrimiento de identificadores expuestos en funciones públicas y la explotación de endpoints predecibles. Una charla accesible para entender cómo fallas de diseño en el control de acceso le abren la puerta a un atacante sin necesidad de exploits complejos. 📅 **Fecha y hora** **Jueves 26 de febrero de 2026** **7:00 PM – 9:00 PM (AST)** 📍 **Lugar** Auditorio INDOTEL, Zona Colonial, Santo Domingo 🎥 **Transmisión en vivo (gratuita)** https://youtube.com/live/IJ7vCKv7ikg?feature=share *(No es necesario registrarse para verlo en línea.)* 💬 **Contribuciones** Si deseas apoyar nuestros eventos y el desarrollo de talento local en ciberseguridad: * [https://www.patreon.com/RedTeamRD](https://www.patreon.com/RedTeamRD) * [https://paypal.me/redteamrd](https://paypal.me/redteamrd)

**This is the biggest party in town!** ***Come help us enjoy the luckiest day of the year!*** The Irish Pub and outside overflow tent have Irish Beer, Whiskey and Food. Inside the giant tent the best local Irish bands perform while Irish dancers parade by and the Columbus fife and drum invade each late afternoon. **COVER CHARGE: $20.00** **4pm** - [Drowsy Lads](http://www.thedrowsylads.com/) Named as “The Best Irish-American Band” the 20 year performing veterans have galvanized their place amongst Irish and folk music’s must see acts. You’ll have a blast… and the band will be arm in arm beside you! **7pm** \- Ladies of Langford Since 1995, [Byrne’s Pub](https://byrnespub.com/) has served as a Grandview hub for all things Irish. In fact, co-owner Pat Byrne even operates a line of craft Irish whiskey, known as Bua. The Grandview Spot is also a huge patron of both Celtic music and bluegrass, as live musical guests from both genres perform at Byrne’s on the regular.

We are excited to host Guided Meditations on Sundays at 6 pm in our Ashram/Gallery/Home! !! !! Everyone wants to know what kind of God we worship and what kind of meditation we do. We worship the GOD that LOVES US! We understand that god is an energy and it lives in us as us. Our meditations guide others to actually experience that energy! xoxo We don't just talk about peace, love and affection, we experience it :) Also we are a home not a business, so we enjoy building community one friend at a time. We always build in time for people to mingle & develop friendships! xoxo Much Love, Frank Tennyson Namaste, Frank Tennyson http://photos3.meetupstatic.com/photos/event/a/f/9/9/600_447824953.jpeg

**Caller: Frank Buschelmann** **Band: The Rosenthorns** **Big Scioty Contra Dance** **temporarily returning to our long ago location for Jan-March - First Congregational Church, 444 E. Broad St., Columbus 43215** WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor. Be sure to come for the beginner's lesson from 7:30 - 8:00, followed by dancing 8:00 - 10:30. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner. Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot. For more information contact me or check out our website: [www.bigscioty.com](http://www.bigscioty.com/) Please bring your own refillable water bottle. Snacks to share are always welcome!

This, her mother has told her, is the only way to get a "louding voice" -- the ability to speak for herself and decide her own future. But instead, Adunni's father sells her to be the third wife of a local man who is eager for her to bear him a son and heir. When Adunni runs away to the city, hoping to make a better life, she finds that the only other option before her is servitude to a wealthy family. As a yielding daughter, a subservient wife, and a powerless slave, Adunni is told, by words and deeds, that she is nothing. But while misfortunes might muffle her voice for a time, they cannot mute it. And when she realizes that she must stand up not only for herself, but for other girls, for the ones who came before her and were lost, and for the next girls, who will inevitably follow, she finds the resolve to speak, however she can--in a whisper, in song, in broken English--until she is heard
