    Advanced Persistent Threats (APTs) on Mobile Devices and Enterprise Networks

    Advanced Persistent Threats (APTs) are not ordinary cyberattacks. They are long-term, highly coordinated intrusion campaigns typically executed by well-resourced groups with strategic goals. These groups often include state-sponsored units, cyber mercenaries, or organized criminal operations. Their objective is not quick profit or temporary disruption; their goal is ongoing access, intelligence gathering, and silent control.…

    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…

  • Mobile banking malware & overlay attacks: what they are, why they work, and how to stop them

    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…

    Bluetooth Low Energy (BLE) Attacks and Mobile App Protection

    1. Understanding BLE and Its Security Exposure Bluetooth Low Energy (BLE) has become the foundation for modern wireless communication between IoT devices, wearables, and mobile applications. Its low power consumption and fast connection establishment make it ideal for health sensors, smart locks, and tracking devices.However, this convenience introduces a hidden risk: BLE communications often…

  • Hypervisor-level Exploits: Why VM Isolation Isn’t a Silver Bullet

    Hypervisor-level Exploits: Why VM Isolation Isn’t a Silver Bullet

    Virtualization is everywhere: cloud providers, enterprise datacenters, developer laptops, CI runners. It looks safe — each workload sits in its own virtual machine (VM), separated by the hypervisor. That visual separation lulls engineers into false confidence. Here’s the blunt truth: if the hypervisor breaks, your isolation is meaningless. Hypervisor-level exploits (VM escape, hypervisor compromise,…
