CTFs, Communities, and First Wins
Kebium opened as a public record of learning, setbacks, and progress, then moved into CTF participation, a Discord learning community, and the AI Summer Camp. August brought a serious bug-bounty milestone: independent high-impact vulnerabilities found through a Bugcrowd VDP, alongside the launch of SecDirectory.

Hardening the Practice
The channel shifted toward detailed lessons from Ethiopian Cyber Shield 2026, including server hardening, security controls, Wazuh scans, obfuscation, evasion, and LOLBins. A relaunch then sharpened the focus around programming, Linux, cybersecurity, technical problems, and solutions.
