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 has evolved to include data theft and extortion tactics. This cybersecurity threat targets individuals, businesses, and critical infrastructure, causing significant financial and operational damage.

Also known as: Ransom malware, Crypto-ransomware, Locker ransomware, Ransomware attack, Ransom virus

🧊Why learn Ransomware?

Developers should learn about ransomware to build secure applications and systems that prevent infections, such as by implementing robust authentication, encryption, and backup strategies. Understanding ransomware is crucial for roles in cybersecurity, incident response, and IT operations, where knowledge helps in threat detection, mitigation, and recovery planning. It's also relevant for compliance with data protection regulations like GDPR or HIPAA, which require safeguards against such attacks.
