The Rise of Ransomware: Ransomware Prevention Tips

Ransomware is a type of malware used by cybercriminals that lock your hard drive or encrypt your data for ransom. Ransomware viruses can infect your computer in the form of email attachments that you incautiously download. After download, the virus will encrypt your files stored in the PC and prevent access.

The criminal will then ask for a ransom in exchange for giving back the access to the victim. Most of the time the attacker asks for ransom in the form of Bitcoins or other digital currency so that they can remain undetected.

Impact of ransomware on a business

A successful ransomware attack has a very negative impact on businesses in terms of operational disruption, financial losses, loss of vital data, and reputational loss. According to the Cybersecurity and Infrastructure Agency, an average business usually spends around $130,000 recovering from an attack.

If you are a small business with limited IT expertise or financial strength, ransomware could prove devastating. Therefore, it is vital to incorporate a ransomware mitigation strategy in your cyber defense program.

Let’s find out some tips to prevent ransomware successfully.

Secure the Perimeter

This is the first layer of prevention. You may install any reputed ransomware detection software at the point where data comes into your network, including Wi-Fi. You can use a firewall to block unauthorized access. Use email security best practices while opening any email attachment. Always install the latest software and install security patches as and when required. Securing the perimeter is like installing a burglar alarm in your office. If anything is breached you have time to react.

Run regular security scans

Regular scans are like a second layer of defense against a ransomware attack. Always conduct scanning of your computers and mobile devices as scanning can detect threats from cybercriminals.

Backup your system data

Always keep a backup of your data both locally and in the cloud. This will help you to wipe out the infected system completely and move to a new system with all your data. At the same time, hackers will not get easy access to your data.

Incorporate a strong password policy

With so many digital systems in a business, it is paramount to adopt a strong password management policy for your organization. According to instant checkmate, a background check service provider, 75% of people use the same password for multiple sites. Moreover, they use a very weak and generic password (like abcd1234 or 123456) that is very susceptible to a ransomware attack.

Check twice before clicking on mail attachments

The most common form of ransomware is through an email attachment. Stop clicking on email attachments that contain .vbs, .exe, or .scr as the virus comes in these forms. If somebody sends you a link make sure you know the user or source well. Otherwise, the link may take you to a webpage full of ransomware viruses.

Block vulnerable plug-ins and limit internet connectivity

As an internet user, it is very common that you use browser plug-ins. Attackers use these plug-ins to send ransomware viruses to your network—the most vulnerable plug-ins are Java and Flash. If you have to use it to update your plug-ins regularly and stay safe. In addition, if you deal with critical data keep your network private and away from the open internet. This is a very good way to combat ransomware effectively.

Ransomware attacks can be crippling for your business. Always stay vigilant and try to adhere to these tips. These tips should give you a starting point to develop your comprehensive cybersecurity strategy.
