by specifying a path to a debug symbols file, or using the

options to specify a module to download symbols for.

bt -- Show the current thread's call stack. Any numeric argument

displays at most that many frames. The argument 'all' displays

all threads.

c -- Continue execution of all threads in the current process.

call -- Evaluate an expression on the current thread. Displays any

returned value with LLDB's default formatting.

continue -- Continue execution of all threads in the current process.

detach -- Detach from the current target process.

Defaults to the current function for the current thread and

stack frame.

finish -- Finish executing the current stack frame and stop after

returning. Defaults to current thread unless specified.

image -- Commands for accessing information for one or more target

modules.

j -- Set the program counter to a new address.

p -- Evaluate an expression on the current thread. Displays any

returned value with LLDB's default formatting.

parray -- Evaluate an expression on the current thread. Displays any

returned value with LLDB's default formatting.

po -- Evaluate an expression on the current thread. Displays any

returned value with formatting controlled by the type's author.

poarray -- Evaluate an expression on the current thread. Displays any

returned value with LLDB's default formatting.

print -- Evaluate an expression on the current thread. Displays any

s -- Source level single step, stepping into calls. Defaults to

current thread unless specified.

si -- Instruction level single step, stepping into calls. Defaults to

current thread unless specified.

sif -- Step through the current block, stopping if you step directly

into a function whose name matches the TargetFunctionName.

step -- Source level single step, stepping into calls. Defaults to

current thread unless specified.

stepi -- Instruction level single step, stepping into calls. Defaults to

current thread unless specified.

t -- Change the currently selected thread.

tbreak -- Set a one-shot breakpoint using one of several shorthand formats.

undisplay -- Stop displaying expression at every stop (specified by stop-hook

index.)

up -- Select an older stack frame. Defaults to moving one frame, a

numeric argument can specify an arbitrary number.

v -- Show variables for the current stack frame. Defaults to all

arguments and local variables in scope. Names of argument,

local, file static and file global variables can be specified.

Children of aggregate variables can be specified such as

'var-child.x'. The - and [] operators in 'frame variable' do

not invoke operator overloads if they exist, but directly access

the specified element. If you want to trigger operator

overloads use the expression command to print the variable

instead.

It is worth noting that except for overloaded operators, when

printing local variables 'expr local_var' and 'frame var

local_var' produce the same results. However, 'frame variable'

is more efficient, since it uses debug information and memory

reads directly, rather than parsing and evaluating an

expression, which may even involve JITing and running code in

the target program.

var -- Show variables for the current stack frame. Defaults to all

arguments and local variables in scope. Names of argument,

local, file static and file global variables can be specified.

Children of aggregate variables can be specified such as

'var-child.x'. The - and [] operators in 'frame variable' do

not invoke operator overloads if they exist, but directly access

x -- Read from the memory of the current target process.

iOS逆向之旅(越狱篇) — Cycript【优秀的调试工具】

在Cydia中,搜索并安装该插件,这个很简单,就不贴流程了

$cycript -p 可执行文件的名字/进程ID

基础的语法和其他使用,可以查阅 官方文档

我们除了使用常用的一些命令之外,我们编写自定义函数来实现我们的特殊功能,可以提高我们逆向调试的效率

大部分功能我都是从网上copy下来的,只有最后一个是自己动手写的,嘿嘿

相信大家大部分都能看得懂,这里的语法有点怪怪的,js+oc,我也是模仿着写的

现在我要找上面这个登录按钮是哪一个点击事件

现在你已经知道哪个控制器,哪个函数,想hook不就是分分钟的事吗?

非越狱环境下,同样也能使用我们的cy文件,由于MonkeyDev内置了Cycript

导入和使用的方式和上面说的方式是一样的~

iOS逆向工程 -- 看图层的工具

iOS逆向 Reveal FLEXLoader 图层结构

对于iOS逆向,在我们拿到解密后的可执行文件后,我们研究的突破口其实就是界面的所在信息,毕竟在没有任何的针对信息的情况下,去在Hopper中看可执行文件的数据,无异于大海捞针。所以这时候我们需要针对的信息,需要我们hook的控制器或是类名,这样接下来的研究就会有自己的方向了。

学iOS的童鞋都知道这个神器,不管我们在正向还是逆向开发中都可以用到这个查看图层信息的工具,当然在两种情况的使用的方法是不一样的,这儿我主要介绍Reveal在逆向开发中的使用方法。

在用这个工具的时候,其实是踩了很大的坑的。

利用两种方式的使用Reveal工具,在打开需要逆向的APP后,提示The network connection was lost

至于这两种方式:

打开Reveal ,Reveal菜单-Help-Show Reveal Library in Finder -iOS Library

方式一:

注意,这个plist文件的格式不能出错,不然killall SpringBoard命令后出现白苹果,至于他们的bundleid ,直接到APP的目录下看info.plist文件即可。

方式二:

推荐方式

/Library/RHRevealLoader,在手机的Library下建立RHRevealLoader文件夹,之后把libReveal.dylib放进这个文件夹下。

在手机中的设置中找到Reveal-Enabled Applications-你需要的app

之后将mac和iOS设备中连接同一个局域网中,打开APP后,在Reveal中查看图层信息

当然如果你也出现了Reveal中无法显示问题时:

解决方法:这个是你的libReveal.dylib有问题,这时候你需要换一个

github下的v2.0中的Reveal.dylib地址

这样将新的libReveal.dylib在手机中替换原来的即可,当然还有一种可能就是连接的局域网网速太差了。

我们期待的结果是:

这个工具是在怎么安装Reveal都安装不了的情况下,去了解的一个可以看图层的工具,这个工具和Reveal不同的是不需要连接Mac电脑,只需要在Cydia中安装并且在设置中开启需要的查看的图层的APP。

可以看到这个工具可以查看APP的文件目录,整个APP的视图构架,当前视图的图层结构,当然还有很多功能等着你去发现。

这个是我们的目标视图的图层结构。

这样通过图层工具我们就比较快的找到我们需要研究的对象了。

iOS逆向之手机远程调试介绍

您可以看一下,这一篇文章 iOS逆向工具之Cydia(iOS)软件介绍

这一篇 iOS逆向工具之Cydia(iOS)软件介绍 文章大概就介绍这么多.

上面我知道密码,还是会输入错误.

正好引入我们的话题 SSH

iOS逆向工具之Cydia(iOS)软件介绍 这篇文章我只介绍了ssh的使用,本篇介绍一下ssh.

很多朋友会将SSH,OpenSSH,SSL,OpenSSL搞混

1. SSL (Secure Sockets Layer ),网络通信提供安全及数据完整性的一种安全协议,在传输层对网络连接进行加密.

2. OpenSSL是SSL的开源实现,绝大部分HTTPS请求为 HTTP + OpenSSL

3. OpenSSH的加密是通过OpenSSL完成的.

ssh协议一共2个版本 : SSH-1,SSH-2

现在用的比较多的是SSH-2, 注意 客户端和服务端版本要保持一致才能通信

如何在客户端生成一对相关联的密钥(Key Pair):

一个公钥 (Public Key) , 一个私钥 (Private Key)

mkdir .ssh

我已经创建了,这里报错:不能创建目录 .ssh,文件已经存在.

输入命令后,我们就可以免密登录

注意

如果你输入命令仍然要输入密码可以为authorized_keys文件授权

本篇文章介绍了如何免密远程登录手机.

同样,也介绍了SSL,OpenSSH,SSL,OpenSSL,详细介绍SSH.

相信你对远程调试应该是了解了.

iOS逆向工具之Theos(MacOS)介绍

终端执行这个命令就可以安装

正向iOS开发者,Mac上都安装着Xcode.如果你安装多个版本Xcode,指定其中一版本的Xcode就行.

终端执行命令

越狱iPhone下的签名工具(更改授权entitlements),可以为theos开发的程序进程签名 (支持在OS X和iOS上运行)。

我们可以通过终端命令进行安装

-ldid 用于签名

-fakeroot 用于模拟root权限

安装可能要花费一段时间,耐心等待一下.

注意:

关于ldid签名知识点补充

这里要提一下加密算法:

1. 对称加密算法:

RC4,DES,3DES,AES128,AES356等,加解密双方密钥相同.

2. 非对称加密算法:

RSA,Elgamal等,加解密双方使用密钥对.

3. 哈希算法:

注意

苹果签名:

1. 苹果签名 是苹果官方的私钥签名,公钥验证

2. 以数字签名形式进行签名

注意

数字签名

1. 数字签名是非对称密钥加密技术与数字摘要技术的应用.

2. 对指定信息使用哈希算法,得到一个固定长度的信息摘要.

3. 然后再使用 私钥 对该摘要加密,就得到了数字签名.

注意

数字证书:

1. 数字证书是一个文件,由苹果的Apple Worldwide Developer

Relations Certification Authority(WWDR)证书认证中心进行签名

2. 其主要作用是用来标识身份.

注意

证书文件主要包含两部分内容: 证书信息 和 证书签名

1.证书信息

包含用户的公钥,用户个人信息,证书颁发机构信息,证书有效期等信息

2.证书签名

WWDR将上述证书本身内容,通过哈希算法得到一个固定长度的信息摘要,然后使用自己的私钥对该信息摘要加密生成数字签名.

3.证书验证

注意

到这里,ldid介绍完成

dpkg:用于管理deb包.

deb是越狱开发安装包的标准格式,dpkg-deb是一个用于操作deb文件的工具,有了这个工具,Theos才能正确地把工程打包成为deb文件.

有的朋友会使用这个命令

报错 Error: invalid option: --from-bottle

大概意思是:无效的参数,这个有可能和安装的版本原因.

我多次安装后,把参数去掉了

到这里就完成了dpkg的安装.

我们在终端使用命令

sudo git clone --recursive /opt/theos

我们通过git clone 到/opt/theos目录下.

克隆需要一部分时间,我们需要耐心等待一会.

我们在终端添加/opt/thoes目录的所有者

sudo chown -R $(id -u):$(id -g) /opt/theos

source ~/.bash_profile

保存环境变量并生效

thoes到这里安装完成.

本篇文章主要介绍了Theos安装前准备.

我们下篇文章会介绍如何是theos,我们会创建tweak demo为大家介绍.

有问题请留言,持续关注.
