What is Ransomware?
Ransomware is a type of malicious software designed to block access to a computer system or encrypt its files until a sum of money (ransom) is paid. Cybercriminals often target individuals, businesses, and even government institutions, causing significant financial and data loss.
How Does Ransomware Work?
Infection: Ransomware spreads through phishing emails, malicious downloads, or software vulnerabilities.
Encryption: Once inside a system, it encrypts files, making them inaccessible.
Ransom Demand: Victims receive a ransom note demanding payment in cryptocurrency.
Decryption (or Not): Some attackers provide decryption keys after payment, while others do not.
Types of Ransomware
Locker Ransomware: Locks users out of their devices.
Crypto Ransomware: Encrypts files and demands payment for decryption.
Scareware: Fake software that tricks users into paying for non-existent threats.
Doxware (Leakware): Threatens to release sensitive data if ransom is not paid.
How to Protect Yourself from Ransomware
Backup Your Data: Regularly back up important files to an external or cloud storage.
Avoid Suspicious Links & Emails: Never click on unknown links or download unverified attachments.
Use Strong Security Software: Install and update antivirus and anti-malware programs.
Keep Software Updated: Apply security patches and software updates to prevent vulnerabilities.
Enable Multi-Factor Authentication: Adds an extra layer of security against unauthorized access.
What to Do If Infected by Ransomware?
Do Not Pay the Ransom: Paying does not guarantee file recovery and encourages cybercriminals.
Disconnect from the Network: Prevent further spread to other devices.
Seek Professional Help: Contact cybersecurity experts or authorities.
Restore from Backup: If you have a backup, restore your files without paying the ransom.
Ransomware is a growing cyber threat, but by staying informed and implementing strong security practices, you can minimize your risk. Protect your data, stay vigilant, and never let cybercriminals hold your files hostage.
