Ransomware

Ransomware is a type of malicious software that encrypts a victim's files or blocks access to a computer system until a ransom is paid. It has become one of the most significant cyber threats facing individuals and organizations today.

How Ransomware Works

• Infection: Usually spread through phishing emails, exploit kits, or compromised websites.
• Encryption: Once installed, ransomware encrypts files using strong encryption algorithms.
• Ransom Demand: The attacker demands payment (often in cryptocurrency) for the decryption key.
• Timer: Many ransomware variants include a countdown timer, threatening to destroy the key if payment isn't made.

Protecting Against Ransomware

• Maintain regular, offline backups of important data.
• Keep all software and operating systems updated with the latest security patches.
• Use reputable security software and keep it updated.
• Be cautious when opening email attachments or clicking on links.
• Implement network segmentation to limit the spread of ransomware within an organization.
