With ransomware attacks increasing in frequency, it only makes sense to create a response plan. You already have a disaster recovery plan, so why not include ransomware attack prevention strategies? Whether it’s a disaster like a power outage or a ransomware attack, your losses can quickly add up.

So, what should you include in a ransomware remediation strategy? Even though every business is unique, the steps for an effective prevention strategy remain the same. This is one of the few times a plan can be one size fits everyone.

Understanding Ransomware Mediation

If you’re unsure what ransomware or remediation is, the definitions are pretty easy to understand. Ransomware is software that blocks a user’s access to a computer system or network until a specific sum of money is paid. 

The ransom amount can depend on a few factors, like the hacker’s experience and the size of the affected organization. For example, the healthcare industry will probably be charged a higher ransom than a small mom-and-pop business. After paying the ransom, the hackers return user access.

Now that you understand ransomware better, it’s time to examine the definition of remediation. Ransomware remediation is the strategy an organization uses to remove malicious software from its networks.

Before considering how difficult it can be to remove unwanted software, remember that ransomware blocks access to the affected network. If ransomware is easy to remove, it wouldn’t be an effective tool for hackers. Therefore, you must include ransomware remediation in your DRP (disaster recovery plan).

In addressing ransomware remediation comprehensively, it's pertinent to integrate specific strategies and practices that go beyond immediate recovery efforts. Based on the guidance from the "disaster-remediation" document, here are two additional critical considerations for an effective ransomware remediation approach:

How Can I Identify the Ransomware Type?

Understanding the specific type of ransomware that has infected your systems is a foundational step in the remediation process. Each variety of ransomware, from crypto-ransomware to locker ransomware and scareware, demands a slightly different handling strategy. Here’s how addressing this aspect can be crucial:

• Tailored Response Tactics: Knowing the type of ransomware allows for more customized and effective countermeasures. For instance, crypto-ransomware requires different decryption tools or methods than locker ransomware.
• Enhanced Preparedness: By identifying common ransomware types and preparing specific response strategies for each, organizations can shorten their response time and improve the effectiveness of their mitigation efforts.

Training IT staff to recognize the signs and symptoms of different ransomware types and maintaining an updated database of ransomware signatures and behaviors are practical steps toward this preparedness.

Review of Remediation Options: Which Should I Choose?

Ransomware remediation isn't just about removing the malware; it’s about restoring your systems to regular operation with minimal losses. Here’s how incorporating diverse remediation options can enhance recovery:

• Multiple Recovery Routes: Depending on the attack's nature and severity, different recovery methods can be more or less suitable. Options include restoring from backups, decrypting files using tools provided by cybersecurity firms, or, as a last resort, negotiating with attackers if other pathways fail and the risk/cost assessment supports such a decision.
• Collaboration with Cybersecurity Experts: Sometimes, the in-house expertise may not be sufficient to handle the complexity of specific ransomware attacks. Collaborating with external cybersecurity experts or hiring a dedicated team for ransomware responses can provide the necessary skills and tools for effective remediation.

Continually testing these remediation methods through regular drills or simulations can also ensure that the organization is always ready to deploy them efficiently when an attack occurs.

Incorporating a detailed understanding of the specific types of ransomware and a multifaceted remediation approach can significantly bolster an organization's resilience against these cyber threats. These insights from the "disaster-remediation" document underscore the importance of a nuanced and well-prepared strategy in today's complex cybersecurity landscape, where the variety of threats requires equally diverse strategies to counter them successfully.

How Can I Create an Effective Ransomware Remediation Strategy?

Designing and implementing an effective ransomware remediation strategy may be more straightforward. Best of all, it will help limit your exposure to the malware, minimizing the potential damage.

Locate the Infected System

Sometimes, locating the infected device or system is the most challenging step, particularly for large corporations with hundreds of connected devices. 

But before starting your search, stop all transactions and disable online logins. Hopefully, the hacker hasn’t gotten this information, so don’t give them more opportunities to gain leverage over your system.

It’s time to start searching for infected devices, which may take some time. However, there are a few signs to watch for that often indicate the presence of malware:

• Battery life rapidly decreases
• System performance is subpar
• Unfamiliar software shows up on the network or device
• New accounts are being created without recognizable authorization
• Network traffic is increasing, or the type of traffic is different than normal
• Notice sudden spikes in your disk activity

Another sign is when your backups are being altered or deleted. Backing up data is a crucial step in your DRP. When your backups are being deleted, the financial consequences can be devastating regardless of the size of your operating budget.

Remove the Infected Devices from the Network

Okay, you’ve isolated the infected devices, now it’s time to remove them from the network. You should know that a hacker may monitor the device’s activity to see if and when the malware is detected. But this doesn’t mean you shouldn’t go ahead and remove the device. Just be aware a hacker may be watching. So, how do you remove the infected device? You have a few options.

The simplest way is to unplug the device; just unplug the ethernet cable. You may need to take the network offline if multiple systems are infected. You can also work to isolate infected systems to perform basic daily operations. However, before you continue operations, ensure all infected devices are offline.

Identify the Type of Ransomware

Before starting the remediation process, you must know what type of ransomware you’re dealing with. Yes, there is more than one type of ransomware, and it can be difficult to tell which one is infecting your system.

However, some types of ransomware are more common than others, and this helps make identification easier. The most common is crypto ransomware. This type of malware holds your data hostage until you pay the fee, typically in Bitcoin. You may also be dealing with scareware or locker ransomware.

Scareware masquerades as software designed to fix a fake threat or issue on your computer. Your screen locks up until you pay the ‘repair’ fee. Locker ransomware disables all computer functions except the one used to send payment. Usually, a message on your screen helps you identify the type of ransomware.

Review Your Remediation Options

When you’re ready to start the ransomware remediation process, you have a few options. You can try to remove the malware. Your IT staff may successfully clear it from all devices and systems. You can also turn to your backups if they haven’t been altered. Some hackers alter or delete backups, so this option isn’t always viable.

Another option is to pay the ransom. However, there’s no guarantee that your data will be returned, and even if you get the data back, it may have been altered. Something else to consider is your insurance coverage. 

Your business probably carries cybersecurity insurance and this means you’re following strict backup requirements. You may recover your information without dealing with the hacker’s demands.

Report the Ransomware Attack

Regardless of whether you pay the ransom, you must alert the proper authorities. Who you notify often depends on your industry. Don’t forget to alert your stakeholders and any affected customers.

If you’re wondering who to contact about the cyberattack, a good place to start is with the FBI or U.S. Secret Service. Both government agencies have departments that handle ransomware attacks.

Detailing the Recovery Process: How To Restore Systems from Backups Safely

The recovery process is where the resilience of your disaster recovery plan is truly tested when responding to ransomware attacks. The ability to restore systems safely and effectively can mean a quick return to normal operations and a prolonged period of costly downtime. An integral component of this recovery is the use of backups. However, simply having backups is not enough; the key lies in managing and restoring them.

Best Practices for Backup Management

• Regular Backups: Ensure that you have a scheduled backup process that captures all critical data and systems. These snapshots should be taken frequently to minimize the risk of significant data loss.
• Off-site Storage: Store your backups in an off-site location to protect them from physical disasters like fires or floods. Cloud-based solutions can offer a flexible and secure alternative to physical off-site storage.
• Air-Gapped Solutions: Maintain an "air-gapped" backup, meaning it is not connected to any network and, therefore, inaccessible to hackers. This could involve physical media that are disconnected and stored securely after the backup process.
• Regular Testing: Backups must be tested regularly to ensure they can be restored successfully. Without testing, you cannot be sure your backup will function when needed.

The Importance of Unconnected Backup Solutions

An unconnected or air-gapped backup solution is your ultimate fail-safe. Such a backup means that even if your regular backups are compromised alongside your active systems, you still have a secure copy of your data that the ransomware cannot reach. While these solutions can be more cumbersome, their value becomes indisputable after a widespread attack.

Comprehensive Ransomware Remediation: Beyond Immediate Response

In addition to establishing a structured communication plan, several other critical components to a successful ransomware remediation strategy exist. Here are two additional issues that organizations must consider to bolster their defenses and ensure more resilient recovery efforts when facing ransomware attacks.

Legal and Regulatory Compliance

While responding to the immediate technical challenges of a ransomware attack is crucial, organizations must also be mindful of the legal and regulatory landscape. Here are some factors to consider:

• Reporting Obligations: Many industries and jurisdictions have mandatory reporting requirements for cyber incidents. Companies need to understand these obligations and incorporate them into their response plan. For example, if personal data has been compromised, this might trigger breach notification requirements under laws such as the General Data Protection Regulation (GDPR).
• Data Protection Laws: Compliance with data protection laws is critical. An organization should review how the attack will affect its compliance status and take the necessary steps to protect sensitive customer and employee information by these laws.
• Consultation with Legal Experts: It is advisable to involve legal counsel early in the remediation process. Legal experts can guide the organization through the complexities of making potential ransom payments, interacting with law enforcement, and communicating with stakeholders.

By integrating legal and regulatory considerations into their ransomware remediation strategy, organizations can reduce the risk of subsequent legal challenges or sanctions, which could compound the troubles caused by the attack.

Data Recovery and Business Continuity

Restoring operations quickly is paramount to limit downtime and financial losses in the wake of a ransomware attack. Here are key aspects of data recovery and business continuity to include in the remediation plan:

• Data Backup Systems: Regularly updated backups are the cornerstone of ransomware remediation. Organizations should maintain off-site or cloud-based backups isolated from their network, ensuring they can be used to restore data and systems without being affected by the ransomware.
• Testing Backup Integrity: Having backups is not enough; companies must regularly test them to ensure they can be reliably restored. This includes checking that the data is complete, up to date, and untampered with.
• Developing a Business Continuity Plan (BCP): A comprehensive BCP outlines the steps necessary to maintain essential functions or quickly resume them following a disruption. It should identify critical operations and alternative work methods and clearly outline roles and responsibilities during an incident.
• Prioritizing System Restores: The remediation plan should include a priority list for restoring systems and data based on their criticality to business operations. This ensures that the most vital functions are brought back online first to minimize impact.

A robust remediation strategy encompassing these additional issues — legal and regulatory compliance, data recovery, and business continuity planning — supports a more effective response to ransomware attacks and strengthens the organization's overall cybersecurity posture. By understanding and preparing for these aspects, companies can better mitigate the risks and repercussions of ransomware incidents, safeguard their assets, and ensure the resilience of their operations.
