 These days, most businesses don’t just rely on one cloud provider—they’re spreading their workloads across multiple clouds. This approach, called multi-cloud , gives companies flexibility, cost savings, and better resilience. But it also comes with its fair share of headaches, especially when it comes to security. With different platforms, policies, and tools in play, securing multi-cloud environments has become a complex challenge. In 2025, the stakes are even higher as cyber threats get smarter and regulations get stricter. Let’s explore practical ways to keep your multi-cloud setup safe. Why Multi-Cloud Security Matters Using more than one cloud provider can improve performance and lower costs, but it also increases the attack surface. Some of the main challenges include: Scattered data: Your information might be spread across several clouds, making it harder to track and protect. Different security policies: Each provider has its own default settings, which can le...

Cyber threats have not grown in a straight line; they have changed, become more professional, and adapted to new technology, incentives, and chances. What started out as simple prankware and curiosity-driven worms has turned into a highly organized criminal economy that spans the globe and, more and more, a battlefield where machine learning and generative AI are changing both offense and defense. This article talks about how things have changed over time, focusing on the most important technical and social changes. It also gives useful tips on how to protect systems in a world where attackers can also use intelligence tools. Quick summary (TL;DR) At first, threats were simple: viruses , worms , and basic trojans that spread when they had the chance. Criminalizing and making money off of attacks (ransomware, banking trojans) made them more professional. Nation-state actors made things more complicated: supply-chain compromise, spying, and APTs. Attacks changed from co...

 Read this first: Legal and ethical preface When you reverse engineer mobile apps, you can find out private user data, credentials, and proprietary logic. You should only do reverse engineering if you have clear permission, such as a written agreement, a bug-bounty program scope, your own apps, or a formal pentest agreement. Do not try to get to data or systems that you are not allowed to test. If you find secrets or weaknesses, follow coordinated disclosure: tell the vendor, give them steps to reproduce the problem, and don't publish live secrets. What are JADX and Hopper, and when should you use them? JADX is an open-source Android decompiler that turns APK (DEX) bytecode into Java-like source code that you can read. Great for quickly looking at the structure of an app, including its packages, classes, methods, resources, and manifest. Quick, with both a graphical user interface (GUI) and a command line interface (CLI), this is great for static analysis that focuses on An...

  . Goal & Requirements Goal Use Burp Suite to intercept and inspect network traffic between a mobile app and its backend so you can analyze API requests/responses and find security issues (insecure transport, sensitive data leakage, auth flaws, etc.). Requirements / Prerequisites Burp Suite (Community or Professional). Test devices: Android device/emulator and/or iOS device/simulator (physical device preferred). Same Wi-Fi or USB cable (ADB) connection between device and Burp machine. Basic knowledge of ADB (Android) and Frida (runtime hooking). Frida + frida-server installed for runtime bypass techniques. Optional: objection , apktool , jadx for static changes and binary analysis. Burp CA certificate exported for installation on test devices. 2. Lab Setup — Repeatable & Isolated Why isolation matters Keep tests reproducible and prevent accidental leaks or interference with production networks. Use a dedicated VM or a separate laptop fo...
