Cybersecurity 101 from TryHackMe complete! I learned so much from this learning path and especially enjoyed how much of it was hands on real learning! tryhackme.com/certificate/TH… #tryhackme via @tryhackme
Hacking into Windows via EternalBlue tryhackme.com/mattcahill957/… #tryhackme via @tryhackme My cybersecurity portfolio is growing! I walked through initial exploitation, privilege escalation, and hash dumping. Knowing the attack chain makes all the difference for defense.
My new project post breaks down how an L1 SOC Analyst uses a Playbook to manage a critical phishing incident. It’s all about disciplined, step-by-step containment. See the full incident response walkthrough: opsguild.net/2025/09/25/phi… #Cybersecurity #SOCAnalyst #IncidentResponse
In my latest project, I analyzed and responded to a DoS attack, outlining my process for identifying the threat and implementing a fix. Read about my first incident response: opsguild.net/2025/09/23/ale… #Cybersecurity #SecurityAnalyst #ThreatHunting #Networking #CareerTransition

I thought I’d “sample” @DarknetDiaries….. Now I’m 50 episodes in after only 3 weeks. Pretty sure I’ve been socially engineered.
If you’re stuck in research hell, this is your sign: just start something. Here’s my full story and what I learned along the way 👇opsguild.net/2025/09/04/the…
Since then, I’ve been tearing through the material, learning concepts I’d been dreaming about for years. And it all started with a single click.
Feeling stuck figuring out your next move? I was too. Weeks of watching videos, reading articles, and planning… but nothing actually started. Then I did one thing that changed everything 👇
Just posted my first blog! 🚀 I’m sharing a bit about me and what brought me to learning cybersecurity. Curious how I made the leap? Check it out: opsguild.net/my-story/ #Cybersecurity #LearningJourney #CareerChange
