Backdoors at the BIOS Level: When the Infection Lives Below the Operating System
Cyber-attacks usually fight in the world you can see files, processes, drivers. But the most dangerous threats don’t play in that arena. They go underneath everything, burying themselves in the firmware that initializes the machine long before any OS boots. These are BIOS/UEFI-level backdoors, and once they get a foothold, they operate with a…

Hidden Log Manipulation & Tamper Chains: Why Modern Systems Fail Without Cryptographically Verifiable Logging
In any distributed system, logs are the only surviving witnesses when something goes wrong. Code can fail silently, containers can restart, agents can hang, and monitoring dashboards can mislead, but logs capture ground truth — or at least, that’s the assumption. In reality, logs are frequently the weakest security link, and adversaries know this.…

Quantum Vulnerabilities in Today’s Cryptography
A Historical Perspective and a Forward-Looking Defense Strategy For decades, modern cryptography has relied on mathematical problems assumed to be computationally infeasible for classical computers. Algorithms like RSA, Diffie-Hellman, and Elliptic Curve Cryptography (ECC) derive their security from the hardness of factoring large integers or solving discrete logarithms. This design has worked because no…

Advanced Persistent Threats (APT) on Mobile and Network Systems
Advanced Persistent Threats (APTs) represent the highest tier of targeted cyberattacks: long-term, strategic intrusions executed by highly skilled adversaries, often state-sponsored groups or well-funded criminal organizations. Their goal is simple: remain inside a system for as long as possible while silently gathering intelligence, manipulating assets, or preparing for strategic disruption. Unlike common malware or…

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…
