A simple PoC for the Blacknurse attack.

"Blacknurse is a low bandwidth ICMP attack that is capable of doing denial of service to well known firewalls".

Blacknurse apparently makes the CPU hot on:

• Cisco ASA 5515, 5525 (default settings)
• SonicWall
• "Some unverified Palo Alto"
• Maybe more

This attack is 20+ years old, but it didn't had a logo.
