A ransomware attack uses malware to encrypt systems and data, for the purpose of demanding ransom for decrypting the files. In a ransomware attack, cybercriminals hold your data and systems hostage. If you don’t have data protection strategies in place, a ransomware attack can result in a catastrophic data breach and disrupt business continuity. Read on to learn how to create a ransomware data recovery strategy, including five methods for recovering ransomware encrypted files.
In this article, you will learn:
A ransomware attack is an attack carried out with malware that encrypts your systems and data. Attackers demand a ransom to decrypt your data, allowing you to access it again. Often, attackers ask for payment in cryptocurrency since it is anonymous and less traceable. The ransoms demanded can be minor or can be for large sums of money.
The most effective way to protect your systems against ransomware is to prevent it from being installed. The next best way is to anticipate how it can enter your systems and what data is likely to be targeted. This helps you focus protections and ensure that data is backed up before an attack.
To develop a robust data protection strategy, it’s often easiest to start with your data and work from there. The following steps can help you develop a solid ransomware data recovery strategy.
If you have already been affected by ransomware, there are several methods you can try to restore ransomware encrypted files, rather than paying your attacker.
The fastest way to recover from ransomware is to simply restore your systems from backups. For this method to work, you must have a recent version of your data and applications that do not contain the ransomware you are currently infected with. Before restoration, make sure to eliminate the ransomware first. This is typically done by resetting your systems to factory defaults.
If you are using Windows systems, you might be able to recover your data with the Windows System Restore utility. This tool stores point in time backups for your Windows devices which you can roll back to when needed.
To use this utility, go to Control Panel and select System and Security. Next, choose Backup and Restore. When you select “Restore files from backup” you are taken to a wizard that helps you complete the process.
As an alternative to System Restore, Windows provides the ability to restore individual file versions. This feature can help you with specific encrypted files. For this feature to work, your target file must be included in a previous restore point, Windows Backup, or File History.
If you are not trying to recover a Windows device or if you just want to use a third-party solution, you can try using data recovery software. This software can be helpful if you do not have backups or recovery points to restore from. If you need to recover ransomware files, you can use dedicated ransomware backup solutions.
You can use data recovery software to:
These solutions work for both system-created and user-stored data and can recover data from most storage devices. This includes flash drives, hard disks, external storage, and tape drives. This software can also help you recover corrupted or mistakenly deleted data. A few popular solutions are Stellar Recovery, Prosoft Data Rescue, and Disk Drill.
Depending on the type of ransomware you’re infected with, there may be decryption tools available to you. These tools simply break the ransomware encryption placed on your files and systems using algorithms developed by security experts.
There are multiple sources online for these tools, including the No More Ransomware project. Before downloading any tool, however, make sure that the source is trusted. There are many fake tools available that include additional malware.Ransomware-Resilient Backup from Cloudian

Data protection regulations enforce practices that ensure organizations are legally responsible to protect the data of users and customers. Some regulations are enforced locally, while others are implemented according to industries. This article explains what is data protection, including a brief overview of the GDPR, and reviews key practices and technologies that can help you achieve compliance.

Data availability practices and technologies enable you to obtain the performance needed to maintain business continuity. This article explains key data protection practices that can help you handle data availability challenges and ensure operations remain available. Including an introduction to basic concepts, such as Confidentiality, Integrity and Availability (CIA).
Data storage repositories can hold a variety of data types, some more critical than others. This is why data storage security strategies often require data prioritization, before actions are implemented. Once data is assessed and prioritized, appropriate data security measures can be performed. This article explained key data security approaches and popular tools.

Data encryption practices and technologies enable organizations to take data and scramble it until it becomes meaningless. The data is assigned an encryption key that can decrypt and make the data readable again. Encryption is now a mandatory and integral part of data protection strategies, implemented at rest as well as in transit. This article explains the basic concepts of encryption.

Continuous data protection (CDP), or continuous backup, is the process of backing up data every time a change occurs. CDP processes help organizations maintain a continuous journal of data changes, ensuring that there is always a current version of the data to default to during disasters. This article explains how CDP works, including basic concepts and key pros and cons.

While many think cloud vendors are solely responsible for protecting data in the cloud, this is not entirely correct. Cloud vendors operate under a shared responsibility model, which typically determines that the vendor secures the infrastructure of the cloud and the cloud users are responsible for securing the data kept in cloud environments. This article explains key data protection challenges and offers best practices to maintain security and compliance.
