SANS ☛ 22 Seconds to Compromise: How Automated SSH Actors Move From Login to Persistence Before You Can Blink [Guest Diary]
The honeypot runs Cowrie v2.3.0 on a Raspberry Pi 5 with a residential internet connection.

The sensor's logs are archived daily and analyzed for attacker TTPs, campaign patterns, and threat intelligence value.

At first glance, this seems impossible.
Linux only has one filesystem. Your computer only has one root directory (/). So how can a process suddenly see a completely different filesystem?
