Detailed Evaluation
How I got infected:
SM$LE typically enters a system through cleverly disguised phishing emails, malicious attachments, Trojan droppers, or cracked software. Once executed, it encrypts files and shreds shadow copies to make recovery difficult.
What does it do:
Using strong AES and RSA encryption, Smile locks your files and alters your desktop wallpaper. It drops the ransom note SM$LE‑read‑it.txt, demanding $3,000 USD in Bitcoin via Tor-based darknet sites. Victims are given a 72-hour deadline before a threat of permanent key deletion.
Ransom Note Text
The note includes the following message:
SMILE RANSOMWARE
Ooops. Your files have been encrypted by The SMile Ransomware… AES and RSA encryption algorithms…
Pay $3000 worth of bitcoin within 3 days via darknet link or files will be lost forever…

Should You Worry?
Absolutely.
- There’s no guarantee decryptors will work even if you pay.
- Critical data (documents, photos, business files) become inaccessible and possibly lost for good.
- SM$LE may also drop additional malware like info‑stealers (e.g. Vidar), risking more than data loss.
