TURN THREATS
TO STONE.

Kernel-Level Ransomware Defense for Legacy Systems & Servers. Zero AI. Zero False Positives.

Why Medusa FS?

Kernel Interception

Operates beneath the user space. We intercept malicious I/O requests at the lowest OS level before they touch real data.

Infinite Tarpit

Instead of blocking, we trap. Ransomware is fed an infinite stream of junk data, freezing its execution state permanently.

Zero Storage

Our decoy files appear to be gigabytes in size but consume absolutely zero physical disk space. Perfect for legacy hardware.

The Deception Logic

01

Deploy Traps

Virtual files are projected into the system. They look valuable (e.g., passwords.db) but are just illusions.

02

The Trigger

Ransomware scans the drive and attempts to encrypt the decoy. Legitimate software ignores these hidden files.

03

Stasis (SIGSTOP)

The Kernel Driver instantly detects the illegal access, halts the I/O, and sends a STOP signal to the malicious process.
