Fake apps are the latest evolution of brand impersonation, and they’re proving just as dangerous as phishing sites. Fraudsters clone legitimate mobile apps, publish them on official app stores, and trick users into entering credentials — which are then reused in the real app before anyone notices. Given that over 60% of web traffic is now mobile, this form of phishing-driven credential reuse has become one of the top blind spots in mobile fraud defense.

Code reuse has become a foundational practice in modern software development. Some estimates suggest that over 80% of developers today re-use existing code, rather than writing code from scratch, when building software applications. This trend is largely due to the open-source movement, as one might call it. There exists a massive, ever-growing public repository of open-source libraries, frameworks, and components.

Most mobile security conversations start with code: vulnerabilities, misconfigurations, tokens, and flaws. But few discussions focus on a critical dimension—location: not where an app is used, but where its data travels. In modern mobile architectures, dozens of services operate behind the scenes. SDKs phone home. APIs call upstream. CDNs redirect without warning. Within this chaos, a single, silent connection to a sanctioned region can escalate into a compliance crisis.

Malicious APKs (Android Package Kit files) continue to serve as one of the most persistent and adaptable delivery mechanisms in mobile threat campaigns. Threat actors routinely exploit social engineering and off-market distribution to bypass conventional security controls and capitalize on user trust to steal a variety of data, such as log in credentials.

Mobile apps are everywhere. From the moment we wake up and check the weather to staying connected with friends and family, our lives are woven together by apps. They manage our money, track our workouts, store our memories, and even help us find love. But with this convenience comes a hidden cost: our privacy. Every tap, every swipe, every “allow” permission is a potential gateway for data to flow, sometimes to places we never intended.

Modern software delivery depends on speed, scale, and automation. CI/CD pipelines sit at the center of it all. An efficient CI/CD pipeline empowers your teams to develop features faster, respond to market demands quickly, and stay competitive in a crowded market landscape. But with that speed comes risk. What makes CI/CD pipeline security so critical is the level of access these systems have. They interact with your source code, cloud infrastructure, and deployment environments with elevated permissions.

June 2025 has seen WhatsApp back in the headlines—this time for all the wrong reasons. Earlier this month, The National broke the story: WhatsApp’s security is under renewed scrutiny following revelations that Israel remains the only known actor to have successfully exploited it. But if history has taught us anything, it’s this: if one nation-state can do it, others may follow. At Appknox, we decided to verify the current state of WhatsApp’s mobile app security for ourselves.

APIs are the backbone of modern applications, facilitating seamless communication and data exchange. However, this ubiquity makes them prime targets for cyberattacks. As developers, building robust and secure APIs isn't just a best practice; it's a critical responsibility. This blog post provides a comprehensive API security testing checklist to help you identify and mitigate API vulnerabilities, ensuring your APIs are fortified against evolving threats.
