Static or Dynamic Mobile App Security Analysis

Mobile reverse engineering isn’t just for hackers—it’s a shield for defenders too. By dissecting apps, you uncover hidden risks and patch vulnerabilities before they’re exploited. Moroccan pentesters, mastering this skill means turning attackers’ tools into your defense strategy. 🔍 #MobileSecurity #ReverseEngineering

What should version one of a business-critical app include? Version one should not be everything you can imagine. It should be everything needed to prove the core value safely. For a business-critical app, that means user journey, data, security, integrations and measurement before the nice-to-haves.

Runtime instrumentation tools like Frida, Objection, and Cycript are your secret weapons for live app hacking. They let you poke, tweak, and analyze apps on the fly—no source code needed. Perfect for Moroccan pentesters aiming to level up their dynamic analysis game. Ready to inject some power? 🛠️ #Cybersecurity #PentestingTips

For a business-critical app, that means user journey, data, security, integrations and measurement before the nice-to-haves.

Static tools like MobSF and Apktool dig into your app’s code without running it—perfect for quick vulnerability scans. Dynamic tools watch the app in action, catching issues static analysis might miss. Combine both for a full-proof mobile pentest toolkit. Stay sharp, stay secure! 🔍 #MobileSecurity #PentestingTips

Most common errors when implementing mobile OAuth 👇 We've seen all 5 of these in real production apps. 1. Opening the login flow in an embedded WebView instead of the system browser. That's exactly the pattern security teams flag OAuth for native apps to avoid. Users can't tell your embedded login screen from a fake one either. 2. Skipping PKCE because "it's just a mobile app." Your client secret is sitting inside a public binary. It was never a secret. That's exactly the problem PKCE exists to solve. 3. Treating decoded as verified. Base64-decoding the ID token and trusting email/sub from it — without checking the signature server-side. Decoding a JWT tells you what it claims. It doesn't tell you if it's real. 4. Storing tokens in plain SharedPreferences/UserDefaults instead of the Keychain/Keystore. Encrypted storage exists for a reason. 5. No refresh token logic. Users get silently logged out mid-session and blame your app instead of your auth flow. We built the Capacitor OAuth plugin to default to the right answer on all 5 — PKCE, system browser, no accidental footguns. https://lnkd.in/dq3d3q48

Next in comparison week: Raven vs WAF. WAF sees traffic at the edge. Raven shows inside the app. A request can look normal at the perimeter and still trigger dangerous behavior inside the app. Raven proves and prevents runtime abuse. Sees and stops known, unknown, and CVE-less exploit behavior inside the app. Together they deliver layered protection: strong at the edge, smarter inside. https://lnkd.in/d9hQwmqZ #WAF #RuntimeSecurity #ADR #AppSec #ApplicationSecurity

Your app works. But is it ready for what happens outside the happy path? At droidCon USA, Keshia Rose will dive into how mobile apps get abused and what developers can learn from attackers to build more secure applications. Security isn't just a final checklist. It starts with understanding the risks. Join the conversation in Orlando. 👉 https://lnkd.in/eCkVnS9G #droidConUSA26 #AndroidDev #MobileSecurity

One penetration test does not cover both your web application and your mobile app. Many teams assume that once their web application has been tested, their mobile app is covered too. It is not. A web application test focuses on the server and browser layers. A mobile application contains code, configurations, permissions, SDKs, and stored data that exist on the user's device. Those risks are outside the scope of a web security assessment. Even a dedicated mobile penetration test has a limitation. It validates only the version that existed on the day of testing. Every new release introduces changes, whether it is new code, updated SDKs, modified permissions, or additional features. Without testing each release, new security risks can reach production unnoticed. The practical approach is to make security part of the release process. By scanning every build before deployment and every version published to the app store, security stays aligned with the application that users are actually running. Security should not be tied to the date of the last penetration test. It should reflect the version that is live today. When was the version currently in production last tested? #MobileSecurity #ApplicationSecurity #DevSecOps

Your biggest vulnerability might not be in your code. We review the app it's clean. Reviewed, tested, solid. Then we look at what it's connected to. The OAuth scopes nobody narrowed. The API key sitting in the frontend. The webhook that accepts anything, no signature check. An over-permissioned token gives an attacker what your login screen never would. You inherit the risk of everything you integrate with. Test the seams, not just the app.

Certificates and keystores: the silent guardians of your app’s trust. 🛡️ Regular analysis can reveal expired certs or weak keys before attackers do. Pro tip: automate keystore scans to catch misconfigurations early and keep your defenses airtight. #CyberDefense #AppSecurity
