Wifi Code The Captured

Therefore, is is necessary to decode the captured authentication again to obtain clear text username and password.

As long as we are in position to capture network traffic, Wireshark can sniff the passwords going through.

But the question is what kind of passwords Or more precisely passwords from which network protocols can we capture Thats the topic of this article.

Such protocols are called clear text (or plain text) protocols.

Anybody who is in position to see the communication (e.g.

Although it is very old protocol, some organizations still use it today in their networks.

FTP is a plain text protocol and therefore a well positioned attacker can capture FTP login credentials very easily using Wireshark.

The following screenshot shows example of a captured FTP password using Wireshark.

We can extract all the files (e.g.

Wireshark.

Wifi How To Do That

Brad Duncan from PaloAlto Networks wrote an excellent article describing how to do that.

It is used mainly for administration purposes and it is notoriously known for its insecurity.

Because there is no encryption, there is no privacy nor protection against eavesdropping.

This makes it very hard for the organizations to get rid of it completely.

Example of a telnet communication with captured password can be seen in the following screenshot.

It uses port tcp25 and although there is a secure alternative on port tcp464, the port tcp25 is open practically on every mail server today due to the backward compatibility.

However, mail servers within some organizations still support plain text authentication over the unencrypted channel.

This is mostly due to legacy systems within their internal networks.

All that the attacker has to do is to base64 decode the username and password.

That is because SMTP uses base64 encoding to encode the username and password during the transaction.

But we should be careful with this perhaps we dont want to be disclosing private credentials to other parties on the Internet.

It uses port tcp143 and usually requires STARTTLS command to initiate the SSLTLS encryption before any authentication attempts.

But similarly as SMTP, some organizations still support plain authentication over the unencrypted channel.
