Ransomware

Ransomware is a type of malicious software (malware) that encrypts a victim's files or locks their system, demanding a ransom payment (often in cryptocurrency) to restore access. It typically spreads through phishing emails, malicious downloads, or exploiting vulnerabilities, and can target individuals, businesses, or critical infrastructure. The goal is to extort money by holding data or systems hostage, with attackers often threatening to delete files or leak sensitive information if the ransom is not paid.

Also known as: Ransomware attacks, Ransom malware, Crypto-ransomware, Ransomware virus, File-encrypting malware

Why learn Ransomware?

Developers should learn about ransomware to understand cybersecurity threats and implement preventive measures in software and systems, such as secure coding practices, regular backups, and vulnerability management. This knowledge is crucial for roles in cybersecurity, incident response, or any development work involving sensitive data, as it helps protect against data breaches, financial losses, and operational disruptions. Use cases include designing secure applications, conducting security audits, and developing disaster recovery plans.
