Introduction

Ransomware attacks are increasingly targeting healthcare companies, with recent studies showing that over 71% have been affected. Our latest blog aims to equip readers with the knowledge needed to protect themselves and their organizations.

What is Ransomware?

Ransomware is a type of malicious software that encrypts your files, making them unreadable without a decryption key. This key is a complex string of characters that is extremely difficult to break. Traditionally, hackers would demand a ransom for the decryption key, and companies focused on two main strategies:

1. Preventing attacks.

2. Maintaining robust backups.

These backups included both local and off-site copies, ensuring quick data recovery without paying the ransom. However, the nature of ransomware attacks has evolved.

The New Attack Method

Hackers now not only encrypt your files but also steal your data. Even if you have backups to restore your systems, they threaten to release sensitive information unless the ransom is paid. This data can include social security numbers, passwords, medical records, and more. In the healthcare sector, such a data release would be a significant HIPAA violation, leading to hefty fines in addition to the ransom demands.

How Ransomware Spreads

Ransomware is particularly effective against traditional server setups. As more data moves to the cloud, it becomes harder to target. In a physical server environment, a single compromised user can trigger an attack that spreads throughout the network, affecting all connected devices.

For companies with a distributed workforce or remote employees, the risk dynamics change. While it becomes harder for ransomware to spread across a decentralized network, the lack of robust firewalls in home environments increases individual vulnerability. Companies cannot feasibly turn each employee's home into a secure network fortress.

Ransomware as a Service (RaaS)

Yes, ransomware can now be purchased as a service. Disgruntled employees can contact these services, obtain malware, and deploy it within their company's network. Any ransom collected is shared between the service provider and the employee. This makes it crucial to address both external and internal threats.

How to Protect Your Business

Protection strategies must extend beyond traditional firewalls to individual workstations, especially with the rise of remote work. Each device should be fully patched, encrypted, and equipped with up-to-date antivirus software.

Introducing XDR Technology

Extended Detection and Response (XDR) technology offers advanced protection by blocking any communication with ransomware servers. Even if an employee attempts to run malicious software, XDR can prevent it from connecting to its server to obtain the decryption key, effectively stopping the attack.
