Protection from Malicious Software Policy - Incident Management

Ransomware is a type of malware that encrypts your data and asks you to pay a ransom to decrypt it. Ransomware attacks are becoming more common, so it’s important to ensure that you have adequate protection against them.

An organization's activities may be disrupted or stopped by ransomware, which presents management with a choice: pay the ransom and trust that the attackers will honor their promise to restore access, or refuse to pay the money and resume operations independently.

Fortunately, businesses can take precautions against ransomware attacks. This involves safeguarding information and technology from ransomware and preparing for any successful ransomware assaults.

Ransomware Detection Methods and Their Types

Discovery Via Signature

Malware has a distinctive signature made up of details like domain names, IP addresses, and other identifiers. In signature-based detection, active files operating on a system are compared to a library of these signatures. The simplest approach to malware detection, however, it's not always successful.

For each assault, ransomware criminals may produce new software variants with fresh signatures. Malware detection using signatures can't find something it doesn't recognize. Systems become open to new malware variants as a result.

Behavior-Based Detection

Ransomware acts strangely by opening a large number of files and replacing them with encrypted copies. This odd action may be tracked by behavior-based ransomware detection, which can then notify users of it. This detection technique can assist consumers in remaining safe from additional typical cyberattacks.

Detection through unusual traffic

The detection of abnormal traffic is a development of behavior-based detection, but it operates at the network level. In addition to encrypting data to demand a ransom, sophisticated ransomware assaults frequently steal data first to give them more power. Large data transfers to external systems result from this.

Even though ransomware can hide its activities and hide the transfers, it may nevertheless generate network traffic that can be observed. The malware on the computer can be identified by abnormal traffic detection so that users can remove it.

Steps to Take After a Ransomware Attack:

You are not helpless in the face of a ransomware assault! When early detection alerts you to a potential attack, you can safeguard your data by acting quickly.

Regular backups are the first thing you should do to secure your data. An whole network can get infected by ransomware. Keep critical data backed up separately from your primary system so you can swiftly recover if you lose access to it due to a cyberattack.

Isolating the infected machines is the next action you should take after discovering an infection to prevent it from spreading. Once you've determined the strain you're dealing with, utilise the ransom notes to let the authorities know. Restore your backups after that, and then prepare your resistance for the subsequent assault.

It's also essential to Continue to be wary of attacks. By regularly engaging in penetration testing, you can ensure that your security is sufficient. These tests will identify security gaps in your system before they become a problem.
