dnslib模块是用来解析dns包的模块

dnspython用于发送dns请求包

dnslib模块包介绍:https://bitbucket.org/paulc/dnslib/

dns C2思路:通信协议使用dns协议完成，支持文件上传和文件下载，支持命令

执行。使用AES加密通道

参考项目:https://github.com/ahhh/Reverse_DNS_Shell/

AES加密参考:https://blog.csdn.net/hh775313602/article/details/78991340

使用者需要安的模块:

dnspython3,Crypto,dnslib

2019/5/2问题：

Traceback (most recent call last):

File "I:/jb/dns_c2/dns_client.py", line 140, in <module>

obk.beikon()

decode_encrypd = aes.decrypt(base64.decodebytes(data))

File "C:\Program Files\Python37\lib\base64.py", line 546, in decodebytes

return binascii.a2b_base64(s)

binascii.Error: Incorrect padding

执行了cmd后退出在执行别的操作有问题，明天起床用wireshark抓包或者debug一波
