Ransomware is a type of malicious software or malware, that encrypts a victim’s files, rendering them inaccessible. The cybercriminal behind the attack then demands a ransom, typically in cryptocurrency, in exchange for the decryption key. With the growth of digital spaces, ransomware attacks have become increasingly common, targeting individuals, businesses, and even entire city systems.
How does Ransomware work?
The most common ways ransomware finds its way onto a computer or network include:
- Phishing emails: The attacker sends emails that appear legitimate, tricking the recipient into opening an attachment or clicking a link that installs the malware.
- Exploiting vulnerabilities: Cybercriminals often exploit security vulnerabilities in software or applications to introduce their ransomware.
Once the malware is on the system, it silently encrypts files, and then a ransom note appears, demanding payment to retrieve the files.
Protection Measures
Here are some best practices to protect yourself against ransomware attacks:
- Backup Regularly: Ensure you have regular and updated backups of all your important files. Keep these backups offline and on a separate system or cloud service.
- Update and Patch: Always keep your software, OS, and applications updated. Cybercriminals often exploit known vulnerabilities.
- Be Wary of Email Attachments: Be skeptical of unsolicited emails and never open attachments or click links from unknown senders.
- Use Antivirus Software: Ensure you have a reliable antivirus solution that offers real-time protection and frequently updates its virus definitions.
- Educate and Train: If you’re a business, educate your staff about the dangers of phishing emails and the importance of not clicking on suspicious links.
Remember, while paying the ransom might seem like the quickest way to regain access to your files, there’s no guarantee that the cybercriminal will provide the decryption key. Paying up only funds encourages these malicious activities. The best defense against ransomware is prevention and preparedness.
