suspicious-telnet-usage (S312)

Derived from the flake8-bandit linter.

What it does

Checks for the use of Telnet-related functions.

Why is this bad?

Telnet is considered insecure because it does not encrypt data sent over the connection and is vulnerable to numerous attacks.

Instead, consider using a more secure protocol such as SSH.
