**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)

Ciao a tutt\*!

Join us as we get together to see SIRAT, an Oscar-nominated Best International Film from Spain that follows a father, accompanied by his son, goes looking for his missing daughter in North Africa. Here’s a description, trailer and our plan for this event: DESCRIPTION: A father, accompanied by his son arrive at a rave deep in the mountains of southern Morocco while searching for his daughter who vanished months ago at one of these endless, sleepless parties. As their search continues, the journey forces them to confront their own limits. The film is directed by Oliver Laxe and stars Sergi Lopez, Bruno Nunez Arjona and Richard Bellamy. TRAILER: https://www.youtube.com/watch?v=ww-IXHXvS70 BUZZ & ACCLAIM: SIRAT has already won numerous awards, including 4 at the 2025 Cannes Film Festival, along with the Chicago, Montclair and Toronto International Film Festivals! It also earned a whopping 11 nominations at the 40th Goya Awards, including Best Film and Director, and was nominated for Best International Feature Film and Best Sound at this year’s Academy Awards. The film is earning a stellar 92% positive rating on Rotten Tomatoes which calls it “an unforgettable exercise in tension” and “a brutal reminder that the journey can be more important than the destination.” PLAN: We’ll plan for a 7pm-ish showing and will confirm/announce details as the date gets closer. Once showtime is confirmed, advance purchase (via GFC website preferred) is advised! Once you have your ticket, please list your seat number in the Comments section of this event. PARKING: Close, convenient parking is available in the nearby garage (located between 9th and 11th, just off High St). Bring your ticket with you and have it validated at the theater and for $2, you’re covered for the night! Look forward to seeing you there, Dan

**New Dojo Location!** **Draft Day Columbus** 1130 Dublin Road Columbus, OH 43215 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for topic suggestions and people interested in presenting at our monthly meetings. To this end we've set up a survey form at [https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc](https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc)
