What is Ransomware?
Ransomware is malicious software that locks or encrypts your files and demands a ransom, usually in cryptocurrency, to restore access. It spreads through phishing emails or malicious websites, targeting both individuals and businesses.
Types of Ransomware:
1.Crypto Ransomware:
Encrypts files on the infected system, making them unreadable without a decryption key.
2.Locker Ransomware:
Locks the victim out of their system entirely, preventing access to any data or applications.
3.Scareware:
A less harmful variant that falsely claims the system is infected with a virus, demanding payment to fix it.
4.Doxware (or Leakware):
Threatens to release sensitive or private data unless the ransom is paid.
How Ransomware Works:
- Infection: Obtained through phishing emails or vulnerabilities.
- Encryption/Locking: Files or systems are encrypted or locked.
- Ransom Note: It demands the victim to pay for access.
- Keep Software Up-to-Date: Keep your OS and applications updated.
- Install Antivirus Software: Get and update antivirus protection.
- Back Up Your Data: Back up important files regularly to an external device.
- Be Cautious with Emails: Avoid clicking links or opening attachments from unknown senders.
- Enable Firewalls: Install firewalls to prevent unauthorized access.
- Use Strong Passwords and MFA: Use strong, unique passwords and multi-factor authentication.
- Don't Pay the Ransom: There is no guarantee of recovering your files.
- Unplug: Disconnect the internet.
- Recovery from Backup: Using a backup to recover lost file.
- Reporting: Advise authorities, and follow the advice of decryption utilities.
