This tutorial demonstrates how to use Frida to hook Java‑level encryption functions in Android apps, covering preparation utilities, self‑exfiltration of MD5, SHA1, MAC, DES/AES/RSA, and signature algorithms with detailed code snippets and visual examples.
This comprehensive tutorial walks through using Frida to hook Android applications, covering official API references, loading APKs, hooking normal and static methods, modifying parameters and return values, handling constructors, inner and anonymous classes, enumerating loaded classes and methods, dynamic dex loading, selective hooking, and practical examples such as programmatically clicking a login button, all illustrated with clear code snippets and explanations.
This article walks through a common Python matplotlib visualization issue, showing how to read parameter data, generate multiple gamma distribution curves, add labels and legends, and produce polished plots, with complete code examples and explanations to help readers replicate the solution.
This tutorial walks you through setting up a Python virtual environment, installing Frida and frida‑server on a rooted Android device, configuring the server, verifying the connection, and writing JavaScript hooks to intercept login functions, complete with code snippets, command examples, and troubleshooting tips.
The article explains how AI tools like DeepSeek lower data‑analysis barriers, outlines the new CDA curriculum with three skill levels, describes essential business‑analysis abilities—from status visualization to attribution and quantitative strategy—and highlights the updated textbooks designed to boost professionals' competitiveness in the AI era.
This article explains how to use XPath in Python to skip the first table header row during web scraping, provides a concise code example, and discusses alternative approaches, helping readers efficiently extract desired list items from HTML structures.
This article walks through reverse‑engineering an Android login flow using Frida to hook methods, analyzes the DES/CBC encryption and MD5 signing process, reproduces the algorithm in JavaScript with CryptoJS, and provides full code and results for verification.
This article shows how to integrate a tqdm progress bar into a Python script that reads multiple Excel files with pandas, concatenates them, and writes the combined result, providing clear code examples and screenshots of the before‑and‑after output.
This tutorial explains why encryption matters in Android reverse engineering, distinguishes standard and custom algorithms, lists common hash, symmetric, and asymmetric methods, and provides complete Java code examples for Hex, Base64, MD5, SHA‑1, MAC, DES, 3DES, AES, and RSA, all runnable in Android Studio.
This article walks through a Python list‑deduplication problem, showing the original data, the expected result, and five distinct code solutions—including itertools, list comprehensions, loops, generators, and enumerate—each illustrated with output screenshots.
