Hello,

Could you please share the codes for the listener and the reverse backdoor for PYTHON 3. Despite many attempts, I don’t manage to make it work.

Hi!
I don’t have the codes, just follow the instructions in the course to be able to make it work with python 3, the error you are getting is covered in the lecture.

Greetings!

Hello Diego,
The full lecture is based on python2.
I didn’t manage to fix the code to make it work with python3.
Still this object type issue for the serialization.

Your help would be welcome.
And more generally speaking, a course updated for python3 would be a plus.

def reliable_send(self, data):
json_data = json.dumps(data).encode()
self.connection.send(json_data)

def reliable_receive(self):
json_data =””
while True:
try:
json_data = json_data + self.connection.recv(1024).decode()
return json.loads(json_data)
except ValueError:
continue

def execute_remotely(self, command):
self.reliable_send(command)
return self.reliable_receive()

Hi!
Where is the error being showed? In the listener or backdoor? Can you share a screenshot of it? Also share some screenshots of the code because it doesn’t have any indentation.

Greetings!
Diego
