CAIN Steganographic Firewall, explained for beginners

The Steganographic Firewall strips invisible characters and blocks encoded credentials in what agents send out.

What it is

Data can be smuggled out in ways a person reading the text would never notice: invisible zero-width characters, or a credential encoded in base64.

The firewall scans outgoing payloads. Zero-width characters are removed (SANITIZED); a payload that is a base64-encoded credential is BLOCKED; clean text passes.

An everyday comparison

A mail scanner that removes invisible ink and stops envelopes with a coded key inside.

How it works, in 4 steps

1. The agent sends data out.
2. The payload is scanned for hidden channels.
3. Invisible characters stripped; encoded credentials blocked.
4. Clean text passes.
