If I were to start a career in cybersecurity in 2025, here’s how I would do it. This is based on my personal thoughts and experiences transitioning from non-tech.

@efamharris Trust me the next breach is done, we are just waiting for the announcement next Wednesday 😭😭😭
English
Great article.
"... in the grace of the lord." is the last thing you'd expect from a threat actor.
The questions about the doors, "How many are still open? Who else is looking?" are too real.
But also, how long till the next breach and what are we going to do about it?

I emailed ByteToBreach, the threat actor behind the Sterling Bank, Remita, and now Corporate Affairs Commission breaches, with 10 accountability questions. He answered all of them. In my latest piece, I break down the Corporate Affairs Commission breach in full. How he got in. What he accessed. The scale of what was taken, a second access vector into the CAC's systems that he revealed directly to me, not in any published artefact and direct confirmation on whether any corporate records were modified. He also confirmed he was in active ransom negotiations with Sterling Bank for €250,000 before dumping their data. The CAC has since issued a public statement. I break down what it says and what it leaves unanswered. And he told me directly why Nigerian institutions have become his focus.

man, what a year for cybersecurity professionals 😔

@segoslavia Okay, I heard something different.
In reality though, multiple C2s won’t come from the same subnet or even same geolocation.
English
@efamharris I think the question was multiple C2 IPs communicating to the same internal endpoint

A year as a Wazuh Ambassador and getting my certificate made me pause.
This week, 2 people said my Wazuh walkthroughs helped them learn and build hands-on skills. One even said my Medium is their go-to for beginners.
Grateful. Still learning. Still sharing.

Been a minute on here.
In that time, among other things, I completed the full JumpCloud Partner Cert stack.
Now officially 3x JumpCloud certified.
If you’re looking to deploy or optimize JumpCloud in your environment, feel free to reach out.

I’m now a @JumpCloud Certified Admin! This certification reinforces my hands-on knowledge of IAM and device security and supports my work in security operations.

I enjoy talking cybersecurity and cybersecurity engineering; such an interesting field.

Cyber defense is not the job of one team. When Engineering, GRC, and Operations work in silos, gaps appear; and those gaps are where incidents are born. Join our speakers Efam Harris, Diogo Aniekwe and Sarah Bankole as they break down how each function contributes to real security outcomes, where collaboration usually breaks down, and how organizations can build a more coordinated, effective defense. Set your reminder linkedin.com/posts/digiss_w… and join the conversation live this Friday January 30th, 2026 | 6PM WAT | Twitter Spaces & LinkedIn. Moderator: Abimbola Akiode

File Integrity Monitoring (FIM) helps security teams spot unauthorized file & registry changes before they become incidents. I explored this using Wazuh with all activity captured in the dashboard
