Post-Quantum Cryptography: The Final Digital Defense Line
The rapid progress of quantum computing has forced a major shift in the foundations of modern cybersecurity. Today’s most widely used cryptographic systems — RSA, Diffie-Hellman, and Elliptic Curve Cryptography (ECC) — were designed under the assumption that certain mathematical problems require an impractical amount of time to solve. Quantum computers break that assumption.…

DNS Spoofing Attacks: When Names Lie
1. What Is DNS and Why It Matters The Domain Name System (DNS) is the backbone of how the internet translates human-friendly names (like google.com) into machine-readable IP addresses. Every time you visit a website, your device queries a DNS server to find the correct IP.In essence, DNS acts as the phonebook of the…

MQTT: The Language of the Internet of Things
Introduction: The Need for Lightweight Communication As the Internet of Things (IoT) continues to expand, billions of devices — from smart thermostats to industrial sensors — need a reliable and efficient way to exchange data. Traditional communication protocols are often too heavy, too power-hungry, or too complex for these small, resource-constrained devices. This is…

Mobile banking malware & overlay attacks: what they are, why they work, and how to stop them
Short version: modern Android banking trojans steal credentials and authorize fraud by placing fake UI layers over real banking apps (or by abusing Accessibility), capturing input and bypassing controls. This attack vector is old, effective, and still widely abused — stop treating it like “user error.” Fix the product and the server, harden the…
