A ransomware attack is one of the most dangerous cyber threats affecting individuals and businesses today. In this type of attack, hackers lock or encrypt a victim’s files and demand payment to restore access.
Ransomware attacks can cause serious financial damage, data loss, and disruption of business operations. Understanding how ransomware works can help users protect their systems and personal data.
What Is Ransomware?
Ransomware is a type of malicious software designed to block access to a computer system or encrypt important files until a ransom payment is made. Cybercriminals usually demand payment in cryptocurrency to avoid being traced.
How Ransomware Attacks Work
1. Infection
The attack usually begins when a user clicks a malicious email link, downloads an infected attachment, or installs unsafe software.
2. File Encryption
Once inside the system, the ransomware encrypts important files, making them inaccessible to the victim.
3. Ransom Demand
The attacker displays a message demanding payment in exchange for a decryption key to unlock the files.
