Telnet Session Interception
Reading Telnet Sessions in Wireshark
# Telnet sends EVERYTHING in cleartext — keystrokes, passwords, output
# Apply filter:
telnet or tcp.port == 23
# Follow TCP stream to read the entire session:
# Right click → Follow → TCP Stream
# You will see the login prompt, username, password, and all commands
# The telnet_router_session.pcap file shows:
# - Router login (ram / pracivo)
# - Commands run after login
# - Router configuration output
# Why this matters:
# Many old routers and network devices still use Telnet by default
# Always use SSH (port 22) instead of Telnet
