Hack The Box Meetup Cáceres #10: Hacking a pasarela de pagos
‼️ **EVENTO 100% PRESENCIAL. NO HÍBRIDO.** La plataforma no nos permite cambiar la modalidad.
Este taller está orientado a **todo tipo de participantes**, con o sin conocimientos previos en ciberseguridad. Sí pedimos unas nociones básicas de informática.
** ¿Qué aprenderás?**
3 Técnicas. 3 Maneras diferentes de hackear un pago online. 3 Fallos que los desarrolladores cometen al implementar sistemas de pagos. ¿4? No. Solo 3.
**** **¿A quién va dirigido?**
A toda persona que le interese saber cómo atacar (o por lo tanto proteger) pagos online.
** ¿A quién no va dirigido?**
Irresponsables, gamberros, inmaduros… Cualquier persona que crea que el poder saltarse la seguridad de un pago online le da derecho a hacerlo.
** ¿Qué necesitas para participar?**
* Un portátil
* Burpsuite (con la versión gratuita te vale)
‼️ No es necesario saber utilizar la herramienta de Burpsuite. Sin embargo aprovecharás mucho más la clase si tienes nociones básicas. Recomendamos verte este pequeño tutorial de 10 min antes del meetup: https://youtu.be/DqNMVAUUa-E?si=Hmui_9qdYaTQEnq_

101 - Reunión Grupo de R: Jueves 26 de febrero de 2025
***
**Resumen:** Integrar modelos de aprendizaje profundo de Keras en el ecosistema Tidymodels ha sido tradicionalmente como mezclar agua y aceite: Keras es imperativo y basado en grafos, mientras que Tidymodels es declarativo y espera argumentos de configuración fijos. Esta charla presenta kerasnip, un paquete de R que une ambos mundos tratando la topología de la red neuronal como un hiperparámetro más. Se demuestra cómo usar "Bloques de Modelo" y especificaciones dinámicas para ajustar estructura del modelo, como la profundidad, el ancho y las ramificaciones de la red, utilizando herramientas estándar como tune_grid(). Aprenderá a definir planos de modelos flexibles que exponen su estructura como "diales" ajustables, llevando la capacidade de crear modelos complejos de Keras a Tidymodels.

**Charla**
**Título:** Escalando soluciones de observabilidad con el ecosistema de VictoriaMetrics.
**Ponente:** [Jose Gómez-Sellés](https://www.linkedin.com/in/joseluisgomezselles/)
**Puesto**: Product Lead - VictoriaMetrics Cloud
**Mini-biografía:**
Product Manager práctico, con gran interés en la investigación, enfocado en mejorar la eficiencia tanto del software como de los procesos. He construido mi carrera sobre desarrollo de software, ingeniería de sistemas y arquitectura de software en la industria de las telecomunicaciones. Posteriormente, me uní a Red Hat como PM para proyectos de observabilidad como OpenTelemetry, trazado distribuido, Jaeger, Tempo y Kepler.
Mi objetivo es generar un impacto real construyendo comunidad a través del intercambio de conocimiento: enseñando a quienes se inician, participando en actividades de mentoría, entrevistando candidatos y diseñando programas de aprendizaje.
**Descripción de la charla:**
Cuando se trata de escalar soluciones de monitorización de series temporales, las cosas pueden volverse un caos. Esa es una de las razones por las que VictoriaMetrics, miembro Silver de la Cloud Native Computing Foundation (CNCF), comenzó su recorrido hace algunos años. Es un conjunto de soluciones de observabilidad simple, fiable y eficiente, adoptado por muchas organizaciones. Es de código abierto, con una comunidad sólida detrás, y ofrece opciones enterprise y gestionadas (Cloud) para quienes necesitan soporte.
VictoriaMetrics se integra muy bien con muchos estándares, incluyendo Grafana y OpenTelemetry. Además, por si no lo sabías, VictoriaLogs es el nuevo jugador del mercado y está superando seriamente a otras soluciones.
En esta presentación, mostraremos los proyectos Open Source de VictoriaMetrics y en qué se diferencian de otras soluciones, especialmente cuando se trata de escalar desde instalaciones pequeñas y sencillas hasta despliegues masivos en clúster.
¡Ven a descubrir cómo los proyectos de VictoriaMetrics pueden hacer la observabilidad mucho más fácil!

The Avenue Steak Tavern
We’re heading to The Avenue Steak Tavern in Dublin, and yes… it’s as good as you’ve heard.
I love the service. I love the atmosphere. I love that it feels fancy but still lets you laugh a little too loud.
Come join us for great food, better conversation, and a night where nobody’s cooking or doing dishes.
Show up hungry and ready to have a good time.
Rhino Barn Tour @ The Wilds
**Summary**
For this event, we will do the [Rhino Barn Tour](https://www.thewilds.org/rhino-barn-tour) at [The Wilds](https://www.thewilds.org/), a ten-thousand acre conservation center in Muskingum County. It is the largest such center in North America and one of the largest in the entire world.
During this tour, we'll visit The Wilds' rhino herd in their state-of-the-art heated barns and learn how The Wilds' animal management team takes care of one of the largest herds of rhinos outside of Africa and Asia.
**The date and time of this tour**
We will be doing the 1:00 p.m. [Rhino Barn Tour](https://www.thewilds.org/rhino-barn-tour) on Saturday, February 28. The tour is scheduled to last 90 minutes.
**What you need to do to attend**
Signing up here on Meetup will not get you into The Wilds for the tour. You must go out to The Wilds' [website](https://www.thewilds.org/) and [buy a ticket](https://www.thewilds.org/rhino-barn-tour).
Please [purchase your ticket](https://www.thewilds.org/rhino-barn-tour), then sign up here on Meetup so I know how many to expect.
**Attendance cap**
There are only eight total slots/tickets available for this tour. As I obviously have already bought one of the tickets, that leaves seven spaces for everyone else.
If you are interested in this event, I urge you to [buy a ticket](https://www.thewilds.org/rhino-barn-tour) at The Wilds' website as soon as possible. Since their website is obviously public, nothing prevents other people having nothing to do with *GOhio!* from buying their own tickets, thereby potentially taking an available slot away from you.
**Additional notes on attendance**
I have now run several events at The Wilds. While the location of The Wilds and the pricing of the tickets generally leads to small turnouts, the people who have gone have all enjoyed it and were glad they went.
If you've never been to The Wilds and you like zoos or animals at all, you are likely to find any tour at The Wilds to be a rewarding experience.
**Tickets and pricing**
[Tickets](https://www.thewilds.org/rhino-barn-tour) for this tour are $95, or $76 if you're a Wilds' member. I've posted screen shots, below, to help you be sure you're buying tickets for the correct event.
Wilds' memberships pay for themselves if you go to The Wilds at least twice a year, and [Columbus Zoo members](https://www.columbuszoo.org/membership) get a discount on memberships to The Wilds. I will always run at least two events a year at The Wilds.
Tickets for all Wilds' tours must be purchased at least 24 hours in advance of the actual tour.
**Cancellations and refunds**
Per The Wilds' [Cancellation Policy](https://www.thewilds.org/policies): *In order to be eligible for refund and accrue no rescheduling fees, cancellations must be made at least 14 days in advance of reservation. Cancellations made within 14 days of reservation will not receive a refund.*
You may [contact The Wilds](https://www.thewilds.org/contact) at (740) 638-5030 between 10 a.m. and 4 p.m., or you can email them at information@thewilds.org.
**Waiver of liability**
After you purchase your ticket, you will likely be asked to fill out a waiver of liability. This is a very short document and should take you no more than two minutes to complete.
**Where we'll meet**
We will meet at The Wilds, whose actual address is [14000 International Rd, Cumberland, OH 43732](https://www.google.com/maps/place/14000+International+Rd,+Cumberland,+OH+43732/data=!4m2!3m1!1s0x8837dae07a595557:0xa1ceca93325a8bd1?sa=X&ved=1t:242&ictx=111).
Please try to be there by 12:30 p.m. For most Wilds' tours, a shuttle bus will take you to the actual spot of the tour. So think of this as though you're going to the airport to catch a flight. It helps to be on time.
The Wilds generally asks that people arrive at least thirty minutes because the scheduled start time of their tour.
**GPS / Getting to The Wilds**
The Wilds is in a very rural area, but I've never had a problem getting there with my GPS (I have Verizon). I've also uploaded a JPG map, below, of Muskingum County.
Sometimes, though, it's hard to get a signal when you're at The Wilds and getting ready to leave. So you might want to consider downloading an offline map in Google Maps. Your cell phone should pick up a signal, however, within a few minutes after you leave.
The Wilds' Visitor Center does have free Wi-Fi.
**Carpooling?**
If you want to carpool, I recommend discussing this in the comments, below, to this event. While I don't myself carpool, I will do what I can to help you arrange something if I can.
**The weather**
Dress for the weather. Just because the barn is heated doesn't mean it will be warm. And wear closed-toed shoes.
Wilds' tours typically run no matter what the weather is.
**After the tour**
Once we're done with the rhinos, we'll head over to the very highly rated [Y-Bridge Brewing Company](https://ybridgebrewing.com/). The brewery is about thirty minutes from The Wilds, and it will be on the way back to Columbus for most, if not all, of us. The brewery's actual address is [1417 Linden Ave Ste D, Zanesville, OH 43701](https://www.google.com/maps/place/1417+Linden+Ave+d,+Zanesville,+OH+43701/data=!4m2!3m1!1s0x8837edd6cc50824f:0xe3a0af1ccb2aefbf?sa=X&ved=1t:242&ictx=111).
Y-Bridge Brewing does not serve food; however, they have several [food options](https://ybridgebrewing.com/food-options). I encourage you to check these out ahead of time on their website for yourself. However, here are a few of them:
*Within walking distance -- 120 feet away*
* [Angry Bull Saloon](https://www.facebook.com/AngryBullSaloonZanesville/) (pizza & subs)
* The Corner Pub Sports Bar and Grill (classic bar food)
*Delivery options -- [Door Dash](https://www.doordash.com/)*
* [4 Star Pizza](https://fourstarpizza.com/), (740) 452-9300
* [Donatos](https://www.donatos.com/), (740) 452-7900
* [Pizza Cottage](https://www.pizza-cottage.com/), (740) 455-6000

If you live in the area or can't make The Wilds but still want to meet us at the brewery, that's fine too.
