Comprehensive Ransomware Recovery Guide: Your Go-To Resource for Every Step

Ransomware attacks are increasing, affecting up to 85% of firms assessed in 2022. While some organizations elected to pay the ransom, a large percentage of those companies did not get their data returned, and some became victims of a second assault.

Ransomware may bring a firm to its knees, so you must be prepared with strong cybersecurity measures, a thorough backup system, and a robust incident response plan. Companies should thoroughly test backup integrity and rehearse incident response. They must understand how to recover from a ransomware attack as swiftly and efficiently as feasible.

What Is Ransomware Recovery?

Ransomware is one of the most serious risks confronting organizations today. According to the 2023 Data Protection Trends study, the frequency of successful attacks on businesses reached 76% in 2021 and 85% in 2022. Surprisingly, only 55% of the encrypted data could be recovered. Companies impacted lost 45% of their data on average.

There are several varieties of ransomware. To extract large quantities of money, fraudsters often lock people out of their laptops and encrypt data. Other varieties of ransomware include scareware and doxware, which threaten to reveal personal information unless victims pay a ransom.

Ransomware recovery is a series of intentional efforts taken by businesses to lessen the effect of ransomware attacks. Organizations develop a system of immutable data backups and configuration snapshots that enable them to reconstruct their systems if hackers successfully encrypt business data. The efficacy of an organization's backup and data protection systems and what was impacted during the ransomware attack determine successful ransomware recovery.

Get Ready for Ransomware Attacks

Being ready for ransomware is part of business continuity planning, and the danger of an attack is considerable. A successful assault might result in severe data loss and the incapacity of your company to operate as a going concern.

A detailed recovery strategy is required to prepare for a ransomware attack. This strategy should be evaluated and adequately tested on a regular basis. It should include best practices for ransomware protection, such as robust cybersecurity measures and a thorough backup plan.

Establish a Comprehensive Backup Strategy

Hackers understand the value of backups and deliberately target backup servers. Create a safe and thorough backup method, and keep these ideas in mind while creating your backup approach.

  1. 3-2-1-1-0 Rule: This is a development of the traditional 3-2-1 backup strategy. In addition to the original material, it asks for three backups. Backups should be kept on at least two distinct kinds of media, with one copy offshore and one offline. The zero in this version of the rule indicates that you should double-check your backups to ensure no mistakes.
  2. Backup type: Full, incremental, or differential backups may all be part of your backup plan. Full backups are often conducted weekly, whereas incremental or differential backups are made daily. An incremental backup is a second backup that saves any changes since the last full or incremental backup. A differential backup is distinct because it backs up all changes since the last complete backup. With each differential backup, its size grows.
  3. Offsite and cloud-based backups: At least one backup set should be stored offsite on a distant hardened server or in a secure cloud facility such as Amazon S3 cloud object storage.
  4. Immutable backups: Backups should be unchangeable. This implies they are read-only and cannot be updated or deleted for a long time. Immutable backups provide superior ransomware defense.

How to Detect Ransomware Incidents

Early identification of a ransomware infection is critical since it may avert a full-fledged ransomware assault. A ransomware assault has numerous phases. This comprises initial entrance or infection, reconnaissance and staging, and data encryption, among other things. If this behavior is detected, you may isolate the impacted computers and reduce the effect of an attack. Here are three ways to consider:

  1. Determine the signs and indications of ransomware. Early signs of an assault may include abnormally high CPU activity and unusually high read and write activity on hard drives.
  2. Monitor and analyze anomalies in the network. Unexpected network traffic, traffic spikes, restricted network capacity, and unexpected network requests are all indicators of malicious activity.
  3. Solution for security information and event management (SIEM): SIEM software analyzes event log data in real-time using machine learning algorithms to detect risks and suspicious activities.

What to Do in the Case of a Ransomware Attack

Respond promptly and decisively to a ransomware attack. The quicker your response, the better, primarily if you can act before the bad actor encrypts your data. Here are five steps you can take to respond:

  1. Implement your incident response plan: Immediately activate your ransomware containment, isolation, and response strategy and alert top management and all responders.
  2. Isolate and contain infected systems: Determine which systems are affected and disconnect them from your network and the internet. Take pictures and system images of all affected devices.
  3. Notify relevant authorities and law enforcement: Depending on your jurisdiction, you may be required to notify regulatory authorities and law enforcement about the attack.
  4. Engage with cybersecurity expert external support: For ransomware emergency response assistance, contact specialized IT support and cybersecurity firms.
  5. Evaluate legal and ethical considerations in your ransomware incident response: Determine and notify all affected parties. Determine the legal ramifications of data protection, privacy regulations, and your ethical obligations.

Post-Ransomware Attack Strategy

After an attack and after you've recovered, undertake a thorough postmortem analysis to determine what occurred.

  1. Assess the impact and extent of the ransomware attack: Conduct a post-recovery assessment. Determine the entire scope of the assault and its consequences regarding downtime and financial losses. Determine how the hackers obtained access and if the hackers were successful in compromising your backups.
  2. Address vulnerabilities: Identify and repair any hardware and software flaws. After that, retrain your personnel.
  3. Strengthen security: Harden your systems and go over your permissions. Set up more VPNs to further isolate systems. Put MFA practices into action.
  4. Implement long-term risk mitigation strategies: Connect with cybersecurity groups. Learn how to decrease risk, improve security, and safeguard your systems.


Recovery from ransomware is possible. Ransom is not recommended since most firms that pay a ransom only retrieve some of their data. Proper planning for ransomware attacks is critical to a successful recovery. This involves implementing robust security measures and having a solid backup plan. A well-coordinated ransomware response plan and a well-trained workforce are required; early ransomware identification is critical. Another consideration is having a solid backup system that includes several immutable copies. Recognizing the need for ongoing development to respond to changing threats is also important.
