This blog explores crypto seed phrases - what they are, how they work, and why they represent a single point of failure in crypto ownership. It explains how seed phrases are commonly compromised and why human behaviour, not broken cryptography, is usually the real risk.

This blog explores hot wallets, why they’re so convenient, how they’re commonly compromised, and why most crypto losses don’t start with “blockchain hacks” at all. It breaks down the technical and human factors behind hot wallet risk, without fear or hype.

This blog explains how Evil Twin Wi-Fi attacks work by imitating trusted networks and exploiting familiarity rather than force. It shows how a simple connection to the wrong Wi-Fi can quietly expose traffic, credentials, and trust.

This blog explains what a Man-in-the-Middle attack is and how attackers secretly insert themselves into network communications. Once in the middle, traffic can be observed or altered while everything appears to function normally.

This blog explains ARP poisoning, showing how attackers mask MAC addresses to redirect network traffic within a local network while the IP address remains unchanged

When a network blindly trusts the wrong authority, attackers don’t need to break in - they’re invited. Rogue DHCP servers exploit one of the most trusted services on a network, quietly redirecting traffic, assigning malicious gateways, and enabling chained attacks like DNS cache poisoning. Understanding how this works is critical to defending modern networks.

Today I want to tell you about something both brilliant and absolutely mean  in cybersecurity: DNS cache poisoning. You’re basically being sent to the right street… but the wrong house number . Hold onto your seats — I’m about to take you on a little cyber adventure! :) Let me break this down in plain English — because once you understand this, you’ll never look at the internet the same way again. Every website you visit has a “street name” (the domain) and a “house number” (

By ST3MTECH Cybersecurity I want to talk about Smurf attacks as I’ve seen a few in my time (together with DNS cashe poisoning, DHCP attacks and PING of DEATH, but more about those later). With this blog, i hope to help my clients understand in plain English what’s happening to their network, WHY it is happening, and HOW these network attacks can be prevented. So here we go! WHAT exactly is a SMURF attack? Let me ask you this first - ever had someone yell, “DRINKS AT MY HOUS
