See how ransomware renames and 'encrypts' files — without any actual encryption. This is a defense-awareness tool: filenames are transformed using real ransomware patterns, and a realistic ransom note is shown. Nothing here touches your real files.
SIMULATION ONLY — NO REAL ENCRYPTION
This tool only renames a list of filenames you provide. It does not access your filesystem, does not encrypt anything, and is for security awareness training only.
Type any list of file names — they will be transformed using real ransomware patterns
Click “Pay ransom” to simulate what happens when the victim pays — the file name is restored. In reality, payment does not always result in decryption.
This tool exists for security awareness training. If you are a victim of real ransomware, disconnect the affected device from the network immediately, do not pay, and contact a reputable incident response provider or your local CERT.
