Day 100 of #100DaysOfCybersecurity ✅

100 days of learning in public: labs, rules, mistakes and fixes. The last stretch was Sigma, YARA and a Splunk home lab. Biggest lesson: test against clean data too.

Thank you all. 🛡️

@0xVickie_ @malik_cybersec @ife0x01 Consistency isn't doing it perfectly. it's coming back after you miss a day. I missed a few days along the way and caught up. Start small, maybe a 7-day challenge, then build from there. You can do it! 💪
