Ransomware Recovery Guide for Businesses

Let's be real—ransomware attacks are one of the biggest cyber threats facing businesses today. An attacker gets into your systems, encrypts your critical files, and demands a hefty ransom, usually in cryptocurrency. Suddenly, your entire operation grinds to a halt. It’s a nightmare scenario that can cause widespread panic and cripple your business daily operations.

Without a solid ransomware recovery strategy, an attack like this can be a knockout punch. You could be looking at permanent data loss, long periods of downtime, and staggering financial costs. And it's not just about the ransom; you'll also face costs for data restoration, breach investigation, potential regulatory fines, and the loss of business from damaged trust.

We’ve put together this guide to help walk you through the essentials of a ransomware recovery strategy. We will cover everything from the importance of a recovery plan to the step-by- step process of getting your business back on its feet after an attack.

What is ransomware?

Ransomware is a malicious software designed to encrypt data on a computer or network, rendering it unreadable until a ransom is paid. In a ransomware attack, cybercriminals essentially take the victim's data hostage, demanding payment in exchange for a decryption key to restore access. The attacker promises to provide the means to unlock the data once the ransom is paid.

In recent years, a combination of factors has created the ideal conditions for a surge in ransomware attacks. The shift to remote work opened new vulnerabilities, as unsecured home networks became easy targets for cybercriminals seeking access to sensitive business data. As more companies fell victim to these attacks, many opted to pay the ransom to quickly regain access to their data, encouraging other attackers to follow suit.

Ransomware in the wild

The KawaLocker ransomware incident, detailed by Huntress analysts, serves as a real-world example of how ransomware attacks unfold and the tactics used by cybercriminals. In August 2025, a threat actor deployed KawaLocker ransomware, leveraging compromised Remote Desktop Protocol (RDP) accounts to gain access to a victim's system. The attacker used tools like HRSword to disable security measures and extend their reach across the network by enabling RDP on additional endpoints.

The ransomware was deployed to encrypt files on specific volumes, leaving behind a ransom note demanding payment for decryption. The attacker also deleted Volume Shadow Copies and cleared event logs to hinder recovery efforts. Despite these actions, Huntress analysts were able to detect and mitigate the attack, preventing further damage to the victim's infrastructure.

This case highlights the importance of robust security measures, such as securing RDP access and monitoring for suspicious activity, to defend against evolving ransomware threats.

What is ransomware recovery?

Ransomware recovery is the coordinated effort to restore and secure your systems after a ransomware attack. It begins with figuring out how far the ransomware has spread, where it came from, and what damage has been done. Once your team understands the full scope, you have to completely remove the ransomware itself. This usually involves deploying security tools to isolate and eliminate the malicious software from all affected devices and networks.

Why a ransomware recovery plan is non-negotiable

A ransomware recovery plan is your proactive defense. It lays out clear, step-by-step instructions for what to do after an attack, making sure a quick and efficient recovery. Having a plan is crucial for a few key reasons:

Minimize downtime: We all know that time is money, especially during a ransomware attack. A predefined plan helps you quickly isolate infected systems, stop the ransomware from spreading, and kick off the recovery process. This allows you to get your business operations back up and running with minimal disruption.
Restore critical functions faster: When an attack takes down essential systems, a recovery plan acts as your roadmap to get them back online as quickly as possible. This ensures business continuity by prioritizing the restoration of customer-facing services and internal operational systems.
Prevent permanent data loss: Ransomware often aims to encrypt or steal your data. A good recovery plan ensures you have recent, clean backups. This significantly limits the risk of permanent data loss and helps you recover essential data without paying the ransom.
Stay compliant: Many industries, like healthcare and finance, have strict data compliance protection regulations that require a formal incident response plan. A solid recovery plan helps you meet these legal standards, guiding you on how to protect sensitive data and report breaches, which can save you from costly fines and legal trouble.

First steps after a ransomware attack

When a ransomware attack hits, you need to act fast to contain the damage. Here are the immediate steps to take:

Isolate infected systems: Your first move is to disconnect infected computers from the network. Unplug network cables, disable Wi-Fi, and disconnect from any shared drives or cloud services. This stops the ransomware from spreading and protects the rest of your network.
Assess the damage: Figure out which systems, applications, and data have been affected. You need to know the full scope of the breach to focus your recovery efforts and make sure nothing is missed.
Call in the experts: Engage your cybersecurity incident response team. They have the skills and tools to contain the attack, identify the ransomware variant, and guide you through remediation. If you don’t have an in-house team, bring in a third-party expert specializing in ransomware recovery.

Notify stakeholders: Depending on industry regulations, you may be legally required to inform customers, partners, and regulators about the breach, especially if sensitive data was compromised.

Building an effective ransomware recovery strategy

A strong ransomware recovery strategy has multiple layers, focusing on preparation, detection, response, and recovery.

Incident Response Plan: This plan should detail the step-by-step process for handling a ransomware attack, including specific roles and responsibilities for your response team.
Regular Backups: Frequent and reliable backups are your best defense. Store them securely, preferably offline or in an air-gapped location, so the ransomware can't reach them. Test your backups regularly to ensure they work when you need them most.
Endpoint Detection and Response (EDR): EDR tools, like Huntress Managed Endpoint Detection & Response continuously monitor for suspicious activity, allowing you to detect and contain threats like ransomware before they cause significant damage.
Employee Training: Human error is a common entry point for ransomware. Empower your team to recognize phishing emails and other social engineering tactics with interactive security awareness training. An informed team is your first line of defense.

Ransomware recovery process in 3 phases

Recovering from a ransomware attack is a structured process designed to minimize damage and restore operations. It’s typically broken down into three phases:

Phase 1: Containment

The first step after detecting an attack is to stop the malware from spreading. Ransomware can move quickly through a network, so immediate containment is critical. This involves disconnecting affected systems from the network to prevent further damage and protect your untouched data.

Phase 2: Eradication

Once the attack is contained, the next step is to completely remove the ransomware from your environment. This involves scanning all affected systems to eliminate any traces of the malware and patching the vulnerabilities that allowed the attack to happen in the first place. This might mean wiping infected machines or restoring them from a known clean image.

Phase 3: Recovery and Restoration

The final phase is all about getting back to normal. This is where your backups come into play. Restore your encrypted files from clean, verified backup copies. Reinstall applications and confirm that all systems are secure and fully operational. Continuous monitoring during this phase is crucial to detect any signs of reinfection.

Backup strategies that work

A solid backup strategy is the foundation of any good ransomware recovery plan. It ensures you can restore your data without giving in to the attackers' demands.

The 3-2-1 Rule: This is a classic for a reason. Keep three copies of your data on two different types of media, with one copy stored off-site. This diversification protects you if one system or location is compromised.
Immutable backups: These are tamper-proof backups. Once created, they cannot be altered or deleted, which means even if attackers gain access, they can't encrypt your backup data.
Air-gapped backups: These backups are physically disconnected from your network, making them inaccessible to ransomware.
Frequent testing: Regularly test your backup and recovery process to ensure your backups are working correctly and that you can restore data quickly in a crisis.

A solid ransomware recovery plan isn’t just a nice-to-have—it’s a must-have for any organization looking to bounce back quickly and keep operations running smoothly after an attack. In today’s ever-evolving threat landscape, staying proactive is the name of the game. With a well-defined recovery strategy, businesses can handle incidents like pros, minimize disruptions, and keep their customers’ trust intact.
