Whether used at home or work, vital data is stored on your computer. Ransomware often goes undetected by computer security software and is used by criminals to block access to this critical information. In exchange for reobtaining access, they’ll attempt to extort money from individuals and companies alike. While ransomware comes in many forms, infections are preventable. 

What Is Ransomware? 

 

Ransomware has been used to extort billions from users since its first incarnation appeared in 1998. When a computer is infected, the virus will create an on-screen notification. It will inform the user that their files or entire system is encrypted, making the machine unusable

 

If paid, the criminal organization will provide a decryption key. If you don’t pay, the decryption key is destroyed, permanently rendering your data inaccessible. In rare instances, the criminal behind the virus will make the data available to the public. 

 

How Does It Work? 

 

Computer SecurityCybercriminals often use phishing attacks. These attacks allow them to spoof the email addresses of legitimate companies. They’ll ask you to confirm your identity by requesting your birthday, social security number, or banking information. This gives the criminals valuable information that they can ransom back. 

 

Sometimes, links or attachments are sent from a spoofed email of someone you trust. When opened, the ransomware will infect the computer. 

 

To scare users, some criminals will pretend to be a law enforcement agency. They’ll claim that they’ve locked the computer due to pornography or pirated software, movies, or music. To restore access, the user would have to pay a fine through Bitcoin, which is untraceable. 

 

While computer security software is effective, some malware programs search for flaws in the system to exploit. 

 

What Are Tips for Preventing Infections? 

 

Preventing an attack is easier than trying to restore a computer that has been affected. Your operating system will provide routine patches and updates to decrease the number of exploitable vulnerabilities. While you should install these updates as they become available, it's wise to avoid any programs you do not recognize. Ask a systems administrator to review any software that requests administrator-level access to verify its authenticity.

 

Consult with computer security professionals. They can analyze your system for vulnerabilities and suggest changes. They'll recommend antivirus software that will detect ransomware. Technicians can also install whitelisting software to prevent the execution of unauthorized programs and applications. 

 

While it doesn’t help prevention, you should always keep backups of your important files via cloud storage or external hard drives, minimizing the damage done by ransomware viruses.
