App Store Release Readiness: Know What Could Get Your App Rejected

Product launch: Appknox now checks every uploaded build against Apple App Store and Google Play submission requirements, so blockers surface while you can still fix them. Many mobile release processes have a security gate. Fewer have a store gate, so the first full check against Apple's and Google's rules often happens after the build is final and the date is public. That's the gap Appknox Store Release Readiness closes.

Best Japan eSIMs for Security-Conscious Travelers in 2026

Landing in Japan without mobile data turns simple tasks into a gamble. You end up hunting for airport Wi-Fi just to load a train map or open a banking app, often on a network you know nothing about. A travel eSIM removes that step. The catch is that plans differ sharply on what "unlimited" means, how much hotspot data you get and which networks carry your traffic.

Why Your App Passes Security Testing but Gets Rejected at the Store

A security scan and an app store review ask different questions. Here's why app store rejection happens to secure builds, and what enterprise mobile teams check before they submit. Your build passed binary SAST. DAST ran clean on real devices. QA signed off, and the launch date went out to customers. Then the store console said no. Nothing in the security report was wrong. It was answering a different question.

CVE-2026-112621: How a Link Preview Could Crash Apple Messages

In this blog, I'll explain how I found the LinkPresentation out-of-bounds write, later assigned CVE-2026-112621 and fixed in iOS 27.2 and macOS Golden Gate 27.2. LinkPresentation is the framework Apple uses to build link previews, and on an unpatched Mac, one crafted preview in Messages was enough to crash it. That fix shipped on October 26, 2026, and Apple credited me, Vinay Kumar Rasala (Xplo8E) of Appknox, alongside an anonymous researcher.

Manage Passwords on iPhone Duo With Keeper

A password manager for iPhone Duo helps you store and use unique passwords without having to remember each one. Keeper Password Manager brings passwords and passkeys together in an encrypted vault, with KeeperFill to help you sign in to websites and apps. Keeper’s iOS app is designed for iPhone Duo’s displays. When the device is open, you can browse vault folders and view record details side by side. When it’s closed, the app uses the outer display.

Physical Security Gaps Every Mobile Professional Overlooks

Mobile professionals often protect their accounts more carefully than the devices, documents and bags sitting beside them. A strong password offers limited protection if someone can enter a shared workspace, view confidential information on a screen or leave with an unattended laptop. Physical security deserves the same deliberate planning as digital security. For consultants, remote employees and frequent business travelers, that means controlling access to equipment and building repeatable habits for hotels, coworking spaces, transportation hubs and client offices.

KnoxIQ: The AI Agent That Triages Mobile App Vulnerabilities

KnoxIQ is the agentic triage layer in Appknox. It takes the findings from your SAST and DAST scans, filters out the ones that aren't real and ranks the rest by how exploitable they are in your build. For each one, it shows you how to reproduce it and writes a fix for your app, including a prompt for Claude Code, Cursor, Github Copilot or any AI coding agent.

PHP2Shell and the end of the once-a-year pen test

On October 21, 2026, PHP shipped emergency fixes for two flaws that let anyone on the internet run code on a PHP web server, with no login. The weakness behind them had been flagged in 2024 and then sat, partly because nobody had proved it was exploitable. In 2026, researchers working with AI models proved it within days. Exploit attempts started before the fix shipped, and details leaked a day ahead of schedule. That sequence is the real story of PHP2Shell. The bug matters, but speed matters more.

Top 5 Minimalist iPhone Duo Case Designs

I'll admit it: the first time I saw the iPhone Duo folded shut on a desk, my thought wasn't "what case should this go in?" It was "please don't put anything loud on that." It's a tidy-looking phone. Titanium edges, two muted colors, and a hinge you barely notice once it's closed. Turns out a lot of people are in the same headspace. Fortune Business Insights puts the minimalist lifestyle products market at roughly $11.5 billion this year, and it expects that number to hit $20 billion by 2034. So, yes, owning fewer but nicer things has gone well beyond a Pinterest phase.
