TELNET - authentication

  • Description: Find the user password in this TELNET session capture.
  • Difficulty: Very easy

🔎 Solution​

The pcap file provided in this challenge contains a Telnet connection between 192.168.0.1 and 192.168.0.2. Telnet is a network protocol used to remotely access and control a computer via a command-line interface. Its major drawback is the lack of encryption, which means all transmitted data can be viewed in plaintext.

To analyze the traffic more easily, we can use the Follow TCP Stream feature. From the reconstructed stream, we can see that when the client enters the password user, the Telnet connection is successfully authenticated.
