EDR Can Stop Ransomware Attacks in 3 Ways

Posted by Marbenz Antonio on November 2, 2022

Attacks using ransomware are growing. For criminal organizations, these actions are low-risk and very valuable, but the damage they cause to their target organizations is often devastating.

The average cost of a ransomware assault, excluding the price of the ransom itself, is $4.54 million, according to the 2022 Cost of a Data Breach report. Ransomware attacks also take 49 days longer to find and contain than the typical data breach. Even once the ransom is paid, criminals usually redirect the victim, which is even worse. These assaults threaten a company’s operations, personnel, clients, and reputation.

Here are some steps your business can do to protect itself and avoid getting the dreaded ransomware note.

The First Step in Stopping Ransomware Is the Detection

Despite the appearance of an all-at-once attack, ransomware attacks usually have many stages before they demand payment. The attackers had already gotten access to the network months or possibly years before they sent a ransom note. After achieving initial access, the attackers proceed laterally to achieve administrator-level rights. They eventually succeed in installing the ransomware and encrypting files. The victim doesn’t see the ransomware until after this deployment.

The first step in preventing ransomware attacks is understanding that traditional signature-based antivirus (AV) solutions are insufficient to protect organizations against ransomware because attackers avoid using signature-based malware that can be blocked by AV solutions. This is true and although ransomware attacks are difficult to identify before their final attack.

Understanding the “process steps” of an attack, such as a backup deletion or encryption procedure that starts suddenly, can help identify ransomware by its behavior. An endpoint detection and response (EDR) platform can help in this situation by quickly identifying and removing advanced unknown threats like ransomware.

How EDR Helps in Ransomware Attack Prevention

In the early phases of an attack, an EDR tool can assist stop ransomware attacks and protect your business from potential dangers. EDR can stop ransomware in three different ways:

1. Behavioral detection capabilities: The current EDR’s behavioral detection skills are essential for identifying and thwarting ransomware threats, which are constantly changing and evolving to infiltrate businesses.

EDR, which is powered by artificial intelligence (AI), can recognize suspicious applications and unusual behaviors to detect and stop unknown attacks like ransomware, even when new ransomware variants surface.

A company should use EDR AI engines that use an initial learning model to understand the typical behavior of each endpoint rather than ones that rely on pre-trained models for detection when it comes to successfully identifying ransomware.

2. Threat hunting: An IT system may have undetected risks for months before the attackers decide to use ransomware. Therefore, a modern EDR’s threat-hunting abilities are essential to guarantee a threat-free and clean environment.

A modern EDR platform gives security teams the ability to automate threat hunting and look for important events on endpoints to understand the processes and applications that are currently in use. A strong EDR platform provides teams with a search function and extensive parameters to detect potential risks, have included recognizing “early warning signs” of an attack.

3. Offline protection: Employees are used to being online with a functional internet or virtual private network connection that offers secure access to the network due to shifting work patterns. To provide complete protection, some EDR platforms on the market need to be connected to the EDR back-end server.

Regardless of whether there is a functional internet connection, an EDR solution helps in user protection. This is important when working remotely or traveling since a user could accidentally access a file that has been infected with ransomware. An AI-powered EDR automatically blocks ransomware when it is identified, preventing encryption.
