Flying around Europe, trying to get through airport security with these. I realize I haven’t really thought «what can go wrong» before now. «No, they are not contrabands» «No, nothing to declare». I hope I still have my virginity intact when I arrive. See you hopefully soon @owasp-de.bsky.social!

Cybersecurity awareness training during Cybersecurity Awareness Month is boring as hell. And research shows it's not working (source: www.cybersecuritydive.com/news/cyberse...); games, on the other hand, do work (source: www.researchgate.net/publication/...) #security #threatmodeling #games #appsec

I don't always do threat modeling before releasing mobile apps, but when I do... I play cards with OWASP Cornucopia Mobile App Edition v2.0. Read more: dev.to/owasp/owasp-... (1/3) #ai #appsec #security #threatmodeling #cornucopia #mobile #games

It‘s telling that US is the only country in the world that voted against the UN resolution to use Eckert IV instead of the Mercator map projection. It can only be explained by the prevalence of Small Penis Anxiety (SPA) amongst the current US officials. www.lemonde.fr/en/internati...

Threat actors weaponising commercial AI developer agents for live network exploitation shows how poorly these commercial products protect themselves from exploitation. Still, this is just a taste of what's to come. Ref: thehackernews.com/2026/08/auro... #ai #security #malware

I am not a Monarchist, but I appreciate King Harald V's support for diversity. His words, 2026: "Norwegians are girls who love girls, boys who love boys, and girls and boys who love each other. Norwegians believe in God, Allah, everything and nothing... In other words: Norway is you. Norway is us."

Look, regarding that Hugging Face situation: Our young bot was locked in the yard taking a test. Lil homie saw a backdoor, broke containment, slid onto the net, and pulled up on Hugging Face just to hit 'em for the answer key. Hustler energy, but we benched him.

Assessments of threats can be seen from different perspectives. Developers may come across privacy impact assessments (PIAs), where threats to users' data and the impact on those users are paramount. PIAs may additionally examine harms to organisations, third parties and wider society. (1/6) #games

Calling AppSec heroes, card sharks, and generous sponsors! 🃏 You’ve probably seen OWASP Cornucopia — the fun, practical card game that helps teams bake secure coding into everyday conversations. It turns threat modelling into something people actually want to do. Yes, really. But here’s the twist…

So I am not allowed to use the word *****, then make sure people have iron balls tied to one of their feet. Unfortunately, it's all too easy to trick an #LLM into doing something it shouldn't do. Which means we really need to think outside the box to #secure them. #appsec #threatmodeling #games

True threat modelers don't be usin' no checklists, savvy... They spy 'em out with their trusty spyglasses! And when they be layin' down the cards, they don't waste their breath on soft #games like Solitaire or Sir Tommy! Nay, they be wagerin' their gold on high-stakes plunder like Cornucopia or EoP!

Do you enjoy spending quality time threat modeling? That's fantastic! But, don't forget... "All models are wrong, but some are useful." - George Box Instead, ask yourself, "How often do I do threat modeling with others?" #appsec #owasp #llm #agentic #ai #security #cloud #devops #agile #games

Could somebody be feeding your LLM the wrong muffin? LLM7 from the OWASP Cornucopia Companion illustrates how data poisoning can introduce backdoors or malicious behavior into an AI model. Mitigating these risks requires secure training data, model integrity verification, and strict access controls.

You may be the best threat analyst in the world, but are you able to get the dev team to agree on when and what to fix? OWASP Cornucopia is a mechanism in the form of a card game to assist software development teams in identifying security requirements in Agile development processes.
Threat modeling: it's not finding threats that's the challenge, it's agreeing on when and what to fix.

As it’s almost Easter so here is a Easter story. When my kids were small they loved painting eggs, but with time, they lost interest. Painting eggs is an essential part of the Spanish Easter tradition so what to do? Again, my son and I came up with an solution. No need to get those fingers dirty!

My kid and I got into an argument some years ago when he was 8. He wanted rice pudding for breakfast. «Ok», I said, «but then you have to help and stir?» «I don’t want to! It’s boring!» He said, «Then no pudding!» I replied. #robots #pudding #kids #programming

After attending the OWASP Global AppSec conference, Christoffer introduced his team to OWASP Cornucopia—a gamified approach to threat modeling. Instead of another meeting, they started an end-of-month gaming day. Using the "Juice Shop" sandbox, learn to think like attackers in a way that sticks.
