前言
frida的官方文档写的并不是很好,有些例子好像还有些问题。这就不得不去研究它的源码了。frida的源码有许多个模块,我们这只关注 frida-java-bridge这个模块。为什么呢?这个模块实现了js世界到java世界的单向通道。所以我们主要的代码在这。可以看看这篇文章对frida-java的介绍frida源码阅读之frida-java。
这里我就记录一下frida-java的编译环境搭建
环境
VMware 12
Ubuntu16
Android8.0
步骤
1.下载安装配置Ubuntu16需要使用到的软件
1.安装配置JDK
2.安装配置SDK
3.安装配置NDK
4.编译安装Nodejs
5.编译运行frida-java
这里就跳过安装Ubuntu16虚拟机的步骤了
下载安装配置Ubuntu16需要使用到的软件
配置apt国内软件源镜像
使用清华大学开源软件镜像站
将软件源的配置拷贝到
sudo gedit /etc/apt/sources.list
更新apt
sudo apt-get update
安装curl
sudo apt-get install curl
安装git
sudo apt-get install git
安装配置JDK
下载jdk
http://jdk.android-studio.org/
这里为了方便我在家目录创建一个work目录,有关环境我都安装到这个目录下。读者可以自行选择目录、
mkdir work
将下载的jdk解压
tar -zxvf jdk-8u77-linux-x64.tar.gz
配置环境变量
sudo gedit /etc/profile
加入配置如下,请修改自己的jdk位置
#set java env
export JAVA_HOME=/home/fj/work/jdk1.8.0_231
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH
加载配置
source /etc/profile
查看是否配置成功
fj@ubuntu:~/work/jdk1.8.0_231$ java -version
java version "1.8.0_231"
Java(TM) SE Runtime Environment (build 1.8.0_231-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.231-b11, mixed mode)
安装配置SDK
这里我借助android studio进行下载sdk。
android studio下载地址:http://www.android-studio.org/
下载后移动到work目录,解压运行
tar -zxvf android-studio-ide-191.5977832-linux.tar.gz
cd android-studio/bin
./studio.sh
其他操作和Windows上的as一样
安装sdk版本,我们下载29版本。
这里可以看到as下载的sdk在/home/fj/Android/Sdk,所以我们需要配置这个目录的环境变量
sudo gedit /etc/profile
配置如下,请注意修改自己sdk的位置:
注意配置build-tools/30.0.3 因为编译时会用到dx
#set sdk
export ANDROID_SDK_HOME=/home/fj/Android/Sdk
export PATH=$PATH:${ANDROID_SDK_HOME}/tools
export PATH=$PATH:${ANDROID_SDK_HOME}/build-tools/30.0.3
export PATH=$PATH:${ANDROID_SDK_HOME}/platform-tools
加载配置文件
source /etc/profile
运行dx命令,如果出现以下信息说明成功
fj@ubuntu:~/work/android-ndk-r21d$ dx
error: no command specified
usage:
dx --dex [--debug] [--verbose] [--positions=<style>] [--no-locals]
[--no-optimize] [--statistics] [--[no-]optimize-list=<file>] [--no-strict]
[--keep-classes] [--output=<file>] [--dump-to=<file>] [--dump-width=<n>]
[--dump-method=<name>] [--verbose-dump] [--no-files] [--core-library]
[--num-threads=<n>] [--incremental] [--force-jumbo] [--no-warning]
[--multi-dex [--main-dex-list=<file> [--minimal-main-dex]]
[--input-list=<file>] [--min-sdk-version=<n>]
[--allow-all-interface-method-invokes]
安装配置NDK
ndk下载地址:https://developer.android.google.cn/ndk/downloads/
下载android-ndk-r21d-linux-x86_64.zip这个版本,因为frida的ndk默认版本就是这个
下载后移动到work目录,解压
unzip android-ndk-r21d-linux-x86_64.zip
cd android-ndk-r21d
添加/etc/profile配置
#set NDK env
export NDK_HOME=/home/fj/work/android-ndk-r21d
export PATH=$NDK_HOME:$PATH
加载配置文件
source /etc/profile
查看ndk版本,如果出现以下信息说明成功
fj@ubuntu:~/work/android-ndk-r21d$ ndk-build --v
GNU Make 4.2.1

编译安装Nodejs
这里我使用源码安装,使用apt安装的话版本过老。不支持frida的编译,并且升级麻烦。
$ sudo git clone https://github.com/nodejs/node.git
Cloning into 'node'...
修改目录权限:
$ sudo chmod -R 755 node
使用 ./configure 创建编译文件,并按照:
$ cd node
$ sudo ./configure
$ sudo make
$ sudo make install
查看 node 和npm版本:
fj@ubuntu:~/work/node$ npm -v
7.4.2
fj@ubuntu:~/work/node$ node -v
v16.0.0-pre
编译运行frida-java
使用Git下载frida-java-bridge源码,这里我选择3.9.4,因为我的frida用的就是这个版本
fj@ubuntu:~/work$ git clone https://github.com/frida/frida-java-bridge.git --tag 3.9.4
frida-java对应的版本在test/Makefile下可以看到
frida_version := 12.11.14
修改配置文件
cd frida-java-bridge/
sudo gedit test/config.mk
修改为如下内容
#修改为自己的sdk目录
ANDROID_SDK_ROOT ?= $(shell echo /home/fj/Android/Sdk)
#修改为自己的ndk目录
ANDROID_NDK_ROOT ?= /home/fj/work/android-ndk-r21d
ANDROID_ARCH ?= arm64
ANDROID_ABI ?= arm64-v8a
#因为我们前面在As中下载了29版本,所以可以不用更换
ANDROID_API_LEVEL ?= 29
ANDROID_BINDIR ?= /system/bin
ANDROID_LIBDIR ?= /system/lib64
APEX_LIBDIRS ?= /apex/com.android.runtime/$(shell basename $(ANDROID_LIBDIR)):/apex/com.android.art/$(shell basename $(ANDROID_LIBDIR))
DEBUG_PORT ?= 5042
一般情况修改上面我注释的部分就行了,如果你的机型的架构不一样注意修改一下。

这些信息说明编译成功了,后面的错误是因为我还有没有连接我的手机。
