2 Months ago, I didn't know anything among web3 or blockchain. Fast forward, today, 3 Mediums, 2 Lows and about 6-10 invalids and my first web3 bug bounty crypto check.

Thanks @PatrickAlphaC and @CyfrinUpdraft

@_shreyaaa23 @PatrickAlphaC @CyfrinUpdraft Hey, I'm possibly the wrong person to be asking but what has always worked for me is the basics should be on your fingertips and pick one area and become obsessed. Hope it helps, cheers.

Celebrating Kenya’s CyberGame 2025 Champions

Today, I had the honor of presiding over the CyberGame 2025 Awards at Utalii Hotel, where we honored Kenya’s brightest cybersecurity talents. Organized by the Embassy of the Slovak Republic in Nairobi and the Ministry of Information, Communications and The Digital Economy, the event showcased Kenya’s commitment to advancing cybersecurity. Over 10 weeks, the program attracted over 1,000 participants, with more than 300 actively competing in digital forensics, OSINT, cryptography, and ethical hacking. CyberGame 2025 supports Kenya’s Digital Superhighway and BETA Agenda, strengthening our cyber defenses.

In attendance: - Amb. @Katarína Žuffa Leligdonová ( Slovak Republic) - Zilpher Owiti, ICT Authority CEO (Ag.) - John Paul Okwiri, Konza Technopolis Development Authority (KoTDA) CEO - Emmanuel Kata, ICT Secretary (Security & Audit) & Tony Blair Institute representatives

Top Performers:
🏆 Best Overall: Stephen Waweru, Carlos Githui, Eve Maina

🌟 Youngest Star: Skylar Wamboi

🔐 All-Rounders: Ochieng George, Calvin Ndichu, Washington Adiado

💻 Top Young Adults: Daniel Nthongoi, Victoria Ntinyari

🏅 Industry Pros: James Kilonzo, Peter Nzomo

With over 4.7 million global cybersecurity job gaps, these talents are Kenya’s future in digital security. We’re committed to scaling this initiative for a safer, smarter digital Kenya.
