android-pentesting-tricks

An expert Android application security testing playbook for authorized mobile assessments. It is meant to be loaded when probing an Android app for SSL pinning bypass, exported component abuse, WebView vulnerabilities, intent redirection, root detection bypass, tapjacking, or backup extraction, and it concentrates on the hook specifics and multi-layer bypass chains that base models tend to miss.

SSL pinning bypass is treated as a first-class topic, with a Frida universal approach and a table of hook points spanning X509TrustManager, OkHttp sslSocketFactory and CertificatePinner, HttpsURLConnection, SSLContext, WebViewClient, and TrustManagerFactory, plus quicker paths through Objection, a debug network security config, and Magisk modules such as LSPosed with TrustMeAlready. Component exposure covers launching exported activities with crafted extras and deep links, querying content providers vulnerable to SQL injection or path traversal, sending crafted broadcasts, and starting exported services. WebView coverage ranges from JavaScript-interface remote code execution on pre-API 17 builds to modern issues around file-access flags, loadUrl on tainted input, and deep-link-to-WebView chains that reach the JavaScript bridge in app context. Intent redirection and a root detection bypass section with per-check Frida strategies round out the attack surface.

Routing guidance connects related material: a mobile-ssl-pinning-bypass skill for deeper cross-platform pinning work, an ios-pentesting-tricks skill for the iOS version of the same app, and an api-sec skill for backend testing once traffic is intercepted. A companion FRIDA_SCRIPTS.md provides ready-to-use script templates, detailed hook points for OkHttp, Retrofit, Volley, and WebView, and a root detection bypass script collection. The commands shown lean on adb, Frida, Objection, aapt, and Magisk-based tooling.
