How to Prevent Ransomware on Networks: Tips

I know how dangerous ransomware is for both people and companies. It’s a type of malware that locks your data and demands money to unlock it. If you don’t pay, you might lose your data forever¹. Even important places like hospitals and emergency centers can be hit, making it hard to do their jobs¹.

This article will share tips and strategies to stop ransomware from attacking your networks. By being proactive with your cybersecurity, we can fight back against this threat¹.

Understanding Ransomware: A Growing Cyber Threat

Ransomware is a dangerous malware that worries people, businesses, and groups all over the world². It can take over computers and lock away important data or personal info, asking for money to get it back². Criminals use smart encryption and blockchain to hide their tracks, making it hard to stop and trace these attacks².

What is Ransomware?

Ransomware encrypts files so you can’t access them, until you pay a ransom². These attacks can really hurt, causing big problems for businesses, losing important data, and costing a lot of money². Groups that deal with public info are especially at risk because they handle sensitive stuff².

Types of Ransomware

There are many kinds of ransomware, each with its own way of attacking²³. Some well-known types include:

• Encryption-based ransomware, which locks files and wants a ransom for the key
• Locker ransomware, which blocks the device or system until you pay
• Scareware, which shows fake warnings to make you think your system is infected
• Doxware/leakware, which says it will share your private data if you don’t pay

These ransomware types have gotten smarter and hit more victims over time²³. Knowing about them helps us fight back and protect ourselves better.

More and more organizations are facing ransomware attacks, with 71% of them hit hard and losing about $4.35 million each time³. In 2023, 10% of companies worldwide faced ransomware attacks, up from the year before³. Criminals keep getting better at what they do, using new tricks like Double Extortion to succeed³.

Develop Robust Policies and Procedures

Creating a solid incident response plan is key for handling ransomware attacks. It should involve IT, legal, and admin teams.
