Cyber Alert: New Ransomware Holds Individual File Shares Hostage
What You Need to Know:
- Strong encryption is used to take files hostage
- Each infected device/share has a unique decryption key, so the criminals can charge money for specific file shares.
- There still is no known method to decrypt files encrypted by the newer variants of Dharma ‘.arrow’ without paying the ransom and obtaining the private keys from the criminals.
Reduce your risk of ransomware infections by conducting:
-
- Regular vulnerability scans and penetration tests
- Training and awareness programs
- Backup checks
- Phishing tests
