Complete Ransomware Recovery Guide: A Comprehensive Recovery Roadmap
When digital data is a vital asset, ransomware attacks are a significant threat to businesses and individuals alike. If you find yourself a victim of a ransomware attack, we’ve outlined some steps you can take to help you regain control and minimize damage.
Ransomware Attacks and Their Impact
Before you can protect yourself against ransomware, you must know what it is, who uses it, and what it looks like. Ransomware has become a preferred weapon for cybercriminals due to its high profitability and the relative anonymity it provides. Understanding how these attacks occur and their potential impact is crucial for every organization that wants to prevent and/or recover from a ransomware attack.
A ransomware attack begins when an unsuspecting user downloads or opens a seemingly harmless file or clicks a fraudulent link. This could be disguised as an email attachment, a software update, a website link, or even a malicious online ad. Once initiated, the ransomware encrypts all available files on the infected device, and, without sufficient cybersecurity protections, the infection can spread across the network, paralyzing entire systems.
The first sign of a ransomware infection is usually suddenly inaccessible data or a message stating that your files have been encrypted. Sometimes, a ransom note appears on the screen, demanding payment in exchange for the decryption key. Other signs include slow system performance, the inability to open files, and frequent system crashes.
Assessing the extent of damage caused by a ransomware attack can be challenging. The impact varies depending on the specific variant of ransomware and the scope of the infected network. An isolated infection on a single device might result in minimal damage, while an infection spreading across an entire business network could lead to significant data loss and downtime.
Immediate Steps to Take When Infected
Upon discovering a ransomware attack, immediate action is essential.
“The most important thing is to follow your Incident Response plan,” says Anderson Technologies’ Associate IT Director Lourens de Beer. “This is something all organizations should invest time in and consult with professionals to put together.” Your Incident Response plan will likely outline some of the steps below, but with additional specifics directly related to your operations, systems, and priorities.
If your business doesn’t yet have an Incident Response plan, the first step is to isolate the infected systems from the network to prevent further spread of the malware. Disconnect affected devices and shut them down, thereby limiting the attack’s reach and potential damage. Many ransomware attacks include a self-replication component, so removing the affected systems from the network helps limit additional spread.
“Time is extremely important,” adds de Beer. “Average breakout time, which refers to the amount of time it takes a malicious actor to move between devices on the network has changed from hours to minutes. Having a trusted partner in place to not only be able to call, but that can react quickly, is extremely important.”
Once containment measures are in place, it’s crucial to assess the extent of the attack. Identify which systems have been affected, what data has been encrypted, and the type of ransomware used. This step helps in understanding the scope of the incident and prioritizing the recovery process.
Ransomware recovery can be a complex process requiring specialized knowledge and expertise. Anderson Technologies recommends engaging with cybersecurity professionals and appropriate law enforcement agencies who can guide you through this challenging situation. They can help decrypt files, identify vulnerabilities exploited by the attackers, and ensure your systems are clean before being reinstated.
Law Enforcement Agencies to Call
Cybersecurity & Infrastructure Security Agency (CISA)
Federal Bureau of Investigation (FBI)
United States Secret Service (USSS)
Your State’s Department of Safety
You should never attempt to communicate with the malicious actors who have locked up your systems with ransomware. Even if they promise to restore your data after receiving payment, full restoration rarely happens. In that situation, your company would be out money AND data. Always contact law enforcement and other relevant agencies when you’re affected by ransomware. According to the IBM Cost of Data Breach Report 2023, “This year’s research shows that excluding law enforcement from ransomware incidents led to higher costs. While 63% of respondents said they involved law enforcement, the 37% that didn’t also paid 9.6% more and experienced a 33-day longer breach lifecycle.”
Crafting Your Ransomware Recovery Plan
The first step in developing a ransomware recovery plan is to prepare a response team. This team should consist of members from different departments like IT, operations, HR, legal, and public relations. Each member brings their unique expertise to the table and plays a crucial role in ensuring a holistic response to the attack.
Once your team is in place, the next step is to clearly define roles and responsibilities. This is crucial to ensure that there’s no confusion during a crisis. For instance, while the IT department will be responsible for identifying the breach and mitigating its effects, the PR team will handle communication with the media and stakeholders. The legal team will ensure compliance with data breach notification laws, and the HR department will manage internal communication and employee support.
Ideally, your response team should have a cybersecurity expert who understands the intricacies of ransomware attacks. They can guide the team in understanding the nature of the attack and formulating an effective response strategy.
The responsibility of the cybersecurity expert will be to coordinate with all these departments and ensure that everyone is on the same page. They must also keep the top-level management updated about the situation. Effective communication is key in managing any crisis situation, and a ransomware attack is no different. It’s important to establish clear communication channels for internal and external communication. Internally, there should be a direct line of communication between the response team and management. All updates regarding the attack should be shared promptly. Externally, the PR team should communicate with the media and stakeholders, providing them with accurate information and updates. Additionally, there should be a communication protocol in place for informing affected parties (like customers). This should be done in accordance with data breach notification laws, which may differ depending on your location or industry regulations.
Executing the Ransomware Recovery Process
To start the process of recovering from a ransomware attack, you and your IT security team must first identify the type of ransomware affecting your systems. AI-powered tools analyze things like ransom notes, email addresses, and Bitcoin addresses used by the attacker to identify the specific “brand” of ransomware at play. Many ransomware groups use the same coding with the rise of ransomware as a service.
Never try to remove ransomware on your own; instead, rely on your IT security team. If they do not have access to advanced tools that can locate and safely remove the ransomware applications and code, an outside cybersecurity team will need to be hired.
Once the ransomware is removed, you—rather, your expert IT security team or outsourced help—can start recovering your system through secure backups. Regularly backing up your data offline or in a separate, secure location ensures that even if your primary systems are compromised, you can restore your data without succumbing to ransom demands. Before initiating the restoration process, you must ensure that your backups are not infected. Anderson Technologies does not recommend attempting to recover your systems alone. Without experience and knowledge of what to watch out for, an incomplete “restoration” could prolong the attack.
With clean backups in place and professional guidance, the process of restoring your operations can begin. Prioritize the recovery of critical systems and data, gradually working towards other functionalities. This step also provides an opportunity to reinforce your security measures, patching any vulnerabilities and updating software.
Server Ransomware Recovery
Server ransomware incidents are a different beast altogether. Why? Servers are the heart of your IT infrastructure, housing critical data and applications. A ransomware attack on servers can cripple your entire network, causing significant downtime and loss of revenue.
Moreover, servers often have complex configurations and interdependencies which make recovery even more challenging. Now, imagine trying to recover encrypted data in such an intricate environment. Sounds daunting, doesn’t it? But don’t lose hope just yet.
The key to overcoming server ransomware lies in robust recovery strategies. Work with your cybersecurity team to identify the type of ransomware affecting your servers. Once identified, the team will likely use a variety of methods that may include a sophisticated antivirus or anti-malware tool to remove the ransomware.
Your cybersecurity team will likely focus on data recovery next. If you’ve been proactive and have a recent backup of your server data, you’re in luck. Restoring from a backup is the simplest and most effective way to regain access to your data.
Ultimately, the same strategies that will recover a network will help to recover a server.
Strengthening for the Future: After You Recover from Ransomware
Surviving a ransomware attack is only half the battle won. The real victory lies in strengthening your security post-recovery. It’s time to learn from the past and build a more resilient future.
Start by identifying any and all vulnerabilities in your policies and network security, especially the path that the cyber criminals took to infect your systems in the first place. Then it’s time to invest in advanced cybersecurity solutions that offer real-time threat detection and automated response mechanisms. Regularly update all software and hardware to patch known vulnerabilities and train your team on best practices for cybersecurity.
Most importantly, make data backups a part of your routine, if you haven’t already. Consider adopting a 3-2-1 backup strategy: three copies of your data: two on different media and one stored offsite. This approach ensures you have a fallback option if disaster strikes again. Implementing these robust security measures can significantly reduce the risk of future attacks.
Ransomware Recovery Timeframe and Expectations
The recovery time after a ransomware attack is influenced by several factors, each adding its own degree of complexity to the process.
First, the type of ransomware involved plays a crucial role. Some strains are notoriously tenacious, requiring extensive effort and time to remove and decrypt. Then there’s the size and complexity of your network. A larger, more complex network can mean a longer recovery period.
The speed of your response also weighs heavily. A wildfire is easier to contain when it’s a small blaze rather than a raging inferno. Similarly, the quicker you identify and respond to a ransomware attack, the shorter your recovery time is likely to be.
Ransomware recovery is not a sprint; it’s a marathon. Yes, it’s crucial to act swiftly, but rushing the process can lead to mistakes and further complications.
Here are some best practices that Anderson Technologies recommends to speed up both recovery and detection.
- Make sure you have a good Endpoint Detection and Response (EDR) solution in place on all organization devices.
- Work with your IT team to confirm that backups are immutable so you can maintain the integrity of the data they contain.
- Build a backup plan that includes image-level backups so all devices can be restored quickly.
- Use backup solutions that incorporate visualization. This allows your IT or cybersecurity team to temporarily enable the affected system from a good last backup. This will limit downtime while the system is being worked on.
The timeframe for recovering from a ransomware attack depends heavily on the complexity of systems. With the right IT team and the best foundation, a small business or organization can be fully recovered in 6 to 12 hours. A general goal for recovery is 24 hours. Your recovery time could be shorter or longer depending on all the factors we’ve discussed.
Focusing on thoroughness over speed is the key. Ensure that every trace of the ransomware is removed, all systems are secure, and data is fully restored. A meticulous approach can help prevent re-infection and ensure a smoother recovery journey.
How to Stop Ransomware Before You Are Hit
Did you know that 80% of organizations report that regular security awareness training reduces their team’s susceptibility to phishing attacks, which is one of the most common ways for a ransomware attack to gain footing.

Generative AI and Ransomware: Future Challenges and Solutions
While ransomware attacks can be devastating, a well-planned recovery strategy can help mitigate their impact. A swift response, professional assistance, secure backups, and systematic restoration are the cornerstones of effective ransomware recovery. However, prevention remains the best defense against such threats.
Many endpoint solutions now use some form of AI behavioral analysis to help detect malicious behaviors in a way that can stop ransomware before it has a chance to fully invade a network. AI is extremely promising in the cybersecurity landscape, but, according to de Beer, “the flipside is also true in that many technologies can and will also be used maliciously to work against protections that are currently in place.”
The area of cybersecurity is an ever-evolving landscape that we will truly never see the final form of. The only thing IT and cybersecurity teams can do is continue learning, researching, and making sure to stay up to date on the most current threats.
