We need more cyber talent that is well-rounded (with more than just technical skills), and programs like CyberHerd cultivate that talent.

[Jeffrey @JeffreyCodes]

It's been fantastic to see CyberHerd (the USF Whitehatters Computer Security Club's competitive team) finally getting some proper resourcing.

Putting resources towards collegiate cyber programs like CyberHerd and the clubs that back them benefits the industry massively.

[University of South Florida @USouthFlorida]

#USF’s CyberHerd isn’t your typical cybersecurity team. They’re artists, athletes, musicians—and now, movie stars. Their journey to national collegiate cyber defense competition success is a story of talent, teamwork, and transformation. 🤘

Catch their rise in “The Making of a Defender,” a behind-the-scenes look at how passion and personality are fueling the next generation of cyber defenders.

28 researchers. 9 days. 45 valid critical or high severity issues uncovered.

@amazon's first-ever In-Person Challenge brought together top security researchers to test its systems.

A HackerOne Challenge is more than just a bug bounty—it’s an invite-only, time-bound offensive testing program focused on finding high-impact vulnerabilities fast.
Here’s what this one produced:

👀 222 vulnerability submissions triaged by a dedicated HackerOne pod
💪 129 valid issues: ~60% of all submissions!
💥 12 critical & 33 high-severity findings
🧠 The opportunity for in-house teams to observe researchers’ reconnaissance & attack methodologies firsthand—gaining a deeper understanding of potential security issues

This is what modern, proactive security looks like.

The second-coolest is seeing my graphic work and Horse Plinko shield logo on t-shirts, signs, coins, memes, and on the big screen.

[Jeffrey @JeffreyCodes]

The coolest thing about organizing the Horse Plinko Cyber Challenge these past couple of years is that you get to inspire people to pursue cyber as an industry. And it makes blue-teaming look cool!

So many people having fun with defending a morally questionable plinking company!

Day 2 of #H10131 is here!

Before the submissions close, these researchers are swiftly and expertly putting @amazon and @awscloud products and platform to the test to help support the company’s number one priority: keeping customers’ data secure. 🔒

[HackerOne @Hacker0x01]

We're live in the beautiful city of Edinburgh for #H10131!

For this live event, the world's top researchers will work side by side with the Amazon/AWS team to hunt for potential bugs. This partnership is one important piece of Amazon and AWS's comprehensive approach to security.

Who will take the MVH title? 🧐

2️⃣ talented UCF students have made it to the Olympics of collegiate cybersecurity competitions — being drafted as members of the U.S. Cyber Team. 💻

Dive into the details of their journey, challenges, and what makes them stand out in the world of #cybersecurity.

[Dr. Alexander N. Cartwright @UCFCartwright]

I had an incredible experience at I/ITSEC, the largest simulation conference in the world, held right here in Orange County.

UCF welcomes opportunities to collaborate across government, industry & academia to further student success, faculty scholarship & our collective impact.

[DOE CESER @DOE_CESER]

👑And the winner is... A Team with a Dream from @UCF! They beat 94 teams to take home first place at the 2023 @DOECyberForce Competition. Congrats! Read our latest announcement to learn more about the event @argonne: https://t.co/tVXr6SYgut

[UCF @UCF]

UCF is becoming a cybersecurity dynasty.

One team secured first place and another ranked fourth in the competition against some of the nation’s top cybersecurity students. 💻 Congratulations @HackUCF! 🏆

[Jeffrey @JeffreyCodes]

I helped with this, especially with the Horse Plinko Cyber Challenge, Hack@UCF's beginner-friendly blue-team competition!

[UCF @UCF]

Knight Hacks 2023 drew a record-setting 700 attendees — giving students from across the state the opportunity to develop a project and collaborate with a team, just as they would in their senior design projects, but much earlier. https://t.co/DrXcoztZJt

[Hack@UCF @HackUCF]

On October 7th and 8th, Hack@UCF is hosting a beginner-oriented blue team competition called Horse Plinko. Competitors (the Blue Team) are tasked with defending a network with services from a group of hackers (the Red Team).

@crunchpepper @UCF @HackUCF Tysm!!

[Jeffrey @JeffreyCodes]

It's the end of an era. I am graduating from @UCF with Honors with a Bachelor's in Computer Science.

Thank you all who made university special, and @HackUCF for being amazing! <3

Here's to what's next.

[Jeffrey @JeffreyCodes]

I helped @HackUCF run the inagural Horse Plinko Cyber Challenge, a beginner blue-team cybersecurity competition to get people interested in cybersecurity and provide hands-on training with real technologies in CS and IT. See you all next October! #hpcc0

[Jeffrey @JeffreyCodes]

If you want a behind-the-scenes look at how we are running HPCC, Harrison and I will be discussing how cyber competitions like this one work behind the scenes at today's Hack@UCF meeting, both on Zoom (https://t.co/72dx3ggVRs) and in ENG2-102 at UCF.

I hope to see you there!

[Jeffrey @JeffreyCodes]

The Horse Plinko Cyber Challenge (HPCC) is a student-run cyber competition for beginners. We will be running our inaugural run on-campus in a few weeks, and I can't wait to show you all what we have in store! 🎠

[Hack@UCF @HackUCF]

April 25th Hack@UCF will be collaborating with the UCF Collegiate Cybersecurity Competition team to host the Horse Plinko Cyber Challenge, a beginner friendly blue team competition for UCF students interested in Cybersecurity.

[Jeffrey @JeffreyCodes]

At least the grant is also fixing the parking garage sensors. Lights would probably help as well (taking feedback from drivers), but doubt that's in the grant.

[Jeffrey @JeffreyCodes]

So those solar panels around the UCF campus near the bus stops now apparently show an OpenTripPlanner instance with SPIN scooter and UCF shuttle locations. Except they aren't used for routing???

[Jeffrey @JeffreyCodes]

As a computer scientist, I look for computationally efficient solutions.

In this case, giving Alafaya a road diet seems to be the best solution, if safety is of concern.

Apps and computer vision to alert of pedestrians doesn't solve the actual root problem; it's a bandage.
