三、实战案例一：Android应用加密算法分析

3.1 目标应用分析

假设我们有一个使用AES加密的Android应用，我们需要分析其加密密钥和算法模式。

3.2 Frida脚本编写

// aes_hook.js
Java.perform(function() {
    // 定位加密类
    var Cipher = Java.use("javax.crypto.Cipher");
    
    // Hook Cipher.getInstance方法
    Cipher.getInstance.overload('java.lang.String').implementation = function(transformation) {
        console.log(`[+] Cipher.getInstance called: ${transformation}`);
        var result = this.getInstance(transformation);
        console.log(`[+] Cipher instance created: ${result}`);
        return result;
    };
    
    // Hook init方法获取密钥
    Cipher.init.overload('int', 'java.security.Key').implementation = function(opmode, key) {
        console.log(`[+] Cipher.init called with opmode: ${opmode}`);
        console.log(`[+] Key algorithm: ${key.getAlgorithm()}`);
        console.log(`[+] Key format: ${key.getFormat()}`);
        
        // 获取密钥字节
        var encodedKey = key.getEncoded();
        if (encodedKey) {
            console.log(`[+] Key bytes (hex): ${bytesToHex(encodedKey)}`);
        }
        
        return this.init(opmode, key);
    };
    
    // Hook doFinal方法获取明文/密文
    Cipher.doFinal.overload('[B').implementation = function(input) {
        console.log(`[+] Cipher.doFinal input length: ${input.length}`);
        console.log(`[+] Input data (hex): ${bytesToHex(input)}`);
        
        var result = this.doFinal(input);
        console.log(`[+] Output data (hex): ${bytesToHex(result)}`);
        
        return result;
    };
    
    // 辅助函数：字节数组转十六进制
    function bytesToHex(bytes) {
        return Array.from(bytes, function(byte) {
            return ('0' + (byte & 0xFF).toString(16)).slice(-2);
        }).join('');
    }
});

3.3 执行与分析

# 附加到目标进程
frida -U -f com.example.encryptedapp -l aes_hook.js --no-pause

# 触发加密操作，观察控制台输出

四、实战案例二：iOS应用网络请求拦截

4.1 目标：分析iOS应用的API通信

4.2 Objective-C/Swift Hook脚本

// ios_network_hook.js
if (ObjC.available) {
    console.log("[+] Objective-C runtime is available");
    
    // Hook NSURLSession
    var NSURLSession = ObjC.classes.NSURLSession;
    
    // Hook dataTaskWithRequest:completionHandler:
    Interceptor.attach(
        NSURLSession["- dataTaskWithRequest:completionHandler:"].implementation,
        {
            onEnter: function(args) {
                // args[0] is self
                // args[1] is the request (NSURLRequest)
                // args[2] is the completion handler block
                
                var request = new ObjC.Object(args[2]);
                var url = request.URL().absoluteString();
                var method = request.HTTPMethod();
                
                console.log(`[+] HTTP Request: ${method} ${url}`);
                
                // 打印请求头
                var headers = request.allHTTPHeaderFields();
                if (headers) {
                    console.log("[+] Request Headers:");
                    var keys = headers.allKeys();
                    for (var i = 0; i < keys.count(); i++) {
                        var key = keys.objectAtIndex_(i);
                        var value = headers.objectForKey_(key);
                        console.log(`    ${key}: ${value}`);
                    }
                }
                
                // 打印请求体（如果有）
                var body = request.HTTPBody();
                if (body) {
                    var bodyString = ObjC.classes.NSString.alloc().initWithData_encoding_(body, 4); // NSUTF8StringEncoding
                    console.log(`[+] Request Body: ${bodyString}`);
                }
            },
            onLeave: function(retval) {
                // retval is the NSURLSessionDataTask
                console.log(`[+] Created data task: ${retval}`);
            }
        }
    );
    
    // Hook NSURLResponse 获取响应信息
    var NSURLResponse = ObjC.classes.NSURLResponse;
    
    Interceptor.attach(
        NSURLResponse["- statusCode"].implementation,
        {
            onLeave: function(retval) {
                console.log(`[+] HTTP Status Code: ${retval}`);
            }
        }
    );
}

五、实战案例三：绕过SSL Pinning

5.1 使用Frida绕过证书锁定

// ssl_bypass.js
Java.perform(function() {
    // 方法1：Hook TrustManager
    var X509TrustManager = Java.use("javax.net.ssl.X509TrustManager");
    
    var TrustManagerHook = Java.registerClass({
        name: 'com.example.TrustManagerHook',
        implements: [X509TrustManager],
        methods: {
            checkClientTrusted: function(chain, authType) {
                console.log("[+] Bypassing client certificate check");
            },
            checkServerTrusted: function(chain, authType) {
                console.log("[+] Bypassing server certificate check");
            },
            getAcceptedIssuers: function() {
                return [];
            }
        }
    });
    
    // 方法2：Hook SSLSocketFactory
    var SSLSocketFactory = Java.use("javax.net.ssl.SSLSocketFactory");
    
    SSLSocketFactory.getDefault.implementation = function() {
        console.log("[+] Intercepted SSLSocketFactory.getDefault()");
        return this.getDefault();
    };
    
    // 方法3：Hook OkHttp的CertificatePinner（如果使用）
    try {
        var CertificatePinner = Java.use("okhttp3.CertificatePinner");
        
        CertificatePinner.check.overload('java.lang.String', 'java.util.List').implementation = function() {
            console.log("[+] Bypassing OkHttp CertificatePinner check");
            // 什么都不做，直接绕过
        };
    } catch(e) {
        console.log("[-] OkHttp not found or already hooked");
    }
});

六、高级技巧：Frida脚本优化

6.1 性能优化建议

// 使用setImmediate避免阻塞主线程
Java.perform(function() {
    setImmediate(function() {
        // 耗时的初始化操作
        initializeHooks();
    });
});

// 批量Hook减少性能开销
function batchHookMethods(className, methodNames) {
    var targetClass = Java.use(className);
    methodNames.forEach(function(methodName) {
        try {
            targetClass[methodName].implementation = function() {
                console.log(`[+] ${className}.${methodName} called`);
                return this[methodName].apply(this, arguments);
            };
        } catch(e) {
            console.log(`[-] Failed to hook ${methodName}: ${e}`);
        }
    });
}

// 使用WeakRef避免内存泄漏
var weakRefs = new Map();
function safeHook(className, methodName) {
    var targetClass = Java.use(className);
    var original = targetClass[methodName];
    
    targetClass[methodName].implementation = function() {
        // 使用弱引用
        if (!weakRefs.has(this)) {
            weakRefs.set(this, new WeakRef(this));
        }
        
        console.log(`[+] ${className}.${methodName} called on ${this}`);
        return original.apply(this, arguments);
    };
}

6.2 调试与日志管理

// 分级日志系统
var LogLevel = {
    DEBUG: 0,
    INFO: 1,
    WARN: 2,
    ERROR: 3
};

var currentLogLevel = LogLevel.INFO;

function log(level, message) {
    if (level >= currentLogLevel) {
        var prefix = '';
        switch(level) {
            case LogLevel.DEBUG: prefix = '[DEBUG]'; break;
            case LogLevel.INFO: prefix = '[INFO]'; break;
            case LogLevel.WARN: prefix = '[WARN]'; break;
            case LogLevel.ERROR: prefix = '[ERROR]'; break;
        }
        console.log(`${prefix} ${message}`);
    }
}

// 使用示例
log(LogLevel.INFO, "Hook初始化成功");
log(LogLevel.DEBUG, "详细调试信息");
