How To Handle the Growing Threat of Ransomware

How To Handle the Growing Threat of Ransomware

Key Points in This Article

• Ransomware attacks continue to rise, with criminals targeting businesses and organizations of all sizes and industries.
• When downloaded onto a network, ransomware targets and encrypts key systems rendering them unusable by the owner until a ransom is paid.
• Businesses and organizations will inevitably be targeted, and up to cybersecurity professionals to drive effective organization-wide responses that keep ransomware attacks from succeeding.
• Enterprise software applications like Microsoft 365 have powerful tools that can prevent criminals from gaining a foothold on corporate networks.

Ransomware attacks are on the rise. It’s not hard to see why.

More people, businesses, organizations, and governments are conducting financial transactions online than ever before. And far too many in each group still don’t engage consistently in even basic cybersecurity measures.

Criminals have had success extracting money from large corporations and businesses and organizations of all sizes. And they’ve found success targeting public sector entities like hospitals, universities, and government entities, who’ve failed to exercise appropriate precautions or respond adequately to suspicious network activity.

Cyberattacks can be committed with tools that can be easily purchased online. You can even hire a group of criminals to commit attacks for you these days. Criminals can target individuals and institutions around the world in relative anonymity. And with a patchwork of international laws and dedicated cybercrime law enforcement units, tracking them down and bringing them to justice is often extremely difficult.

And ransomware is proving to be the approach of choice for many criminals and organized criminal gangs. Despite the widespread coverage of this growing threat, many people still aren’t quite sure what it is. And with criminals often gaining the foothold they need from non-IT employees to launch ransomware attacks, everyone must know what they are and what resources are available to mitigate the risk they pose.

What Is Ransomware?

Ransomware is a form of malware that targets key systems and programs and encrypts them. These encrypted systems and programs are inaccessible to their owners and can only be rendered usable again by a code known as a decryption key. When a criminal successfully encrypts vulnerable systems, they’ll offer the decryption key in exchange for a payment or ransom (hence, the term ransomware.)

Many companies are compelled to comply. A ransomware attack that ties up key production management systems could cost a business millions of dollars in revenue and reputational damage. As operations idle, the pressure on a business and its leaders grows, and even though they have no assurance they will receive a decryption key or that it will work, they pay the ransom anyway.

Too often, people still believe that successful cyberattacks stem solely from IT department failures. And while it is true that there is a lot that IT can do to mitigate the threat ransomware poses, non-IT employees often bring this threat to their employer’s front door. Often criminals can load malware onto corporate networks because they’ve gained access credentials from an employee. They may have tricked an employee into providing those credentials through a phishing email or malvertising. Sometimes, they trick an individual into downloading an attachment containing ransomware code.

These scenarios play out frequently in organizations without regular cybersecurity awareness training, strong internal IT governance policies, and weak technical controls. And the results can be catastrophic, with some companies unable to survive the financial, legal, and reputational fallout.

Key Ransomware Statistics: What Businesses Need to Know in 2024/2025

The ransomware landscape is constantly evolving, and staying informed is your first line of defense. Recent data paints a stark picture of the escalating threat businesses face:

These figures underscore one critical truth: the question is no longer if your business will face a ransomware threat, but when and how prepared you’ll be. Proactive defense is not an option; it’s a necessity.

How Businesses and Organizations Can Handle the Threat of Ransomware

Fortunately, there are many steps that businesses and organizations can take to mitigate the risk of ransomware. Some are not technical in nature. Every organization must regularly train all its employees about the evolving field of cyber threats, how they can recognize them, and what steps they should take when they do. Strong IT governance policies must also be in place, along with disciplinary measures when they are violated.

But IT does play a vital role here. Enterprise platforms, like Microsoft 365, have a suite of tools designed to detect, identify, and respond to threats like ransomware and other malware. It’s up to IT departments to unlock and deploy these tools optimally to protect the organization. IT administrators should start by ensuring that the appropriate access controls are implemented. Access to key directories, files, and networks should be restricted to essential employees, which can be done easily using Microsoft 365’s identity and access management tools. Multifactor authentication should also be established.

Too often, overworked IT administrators have offered local access control to different individuals and departments to help them deal with routine yet time-consuming tasks. But providing employees across the organization with greater access allows employees to bypass and disable existing security measures in place, rendering the business more vulnerable. And if a criminal gains access to those credentials, the damage they can do can be catastrophic.

IT administrators must all ensure that firewalls are operational and configured optimally. And while firewalls can keep intruders at bay, your in-house cybersecurity employees or MSSP must keep a close and constant eye on your network activity. Suspicious activity should immediately be investigated to determine the appropriate response. And while Microsoft 365 has robust enterprise security defenses, businesses should consider supplementing them with Managed Detection and Response (MDR), a service many MSSPs offer. It involves proactively hunting and responding to threats across an organization’s IT infrastructure rather than taking a reactive approach and responding when incidents are detected.

Businesses are not immune to cyberattacks even with the most robust security measures. IT administrators must have a well-designed system of backups and plans to retrieve them rapidly when disaster strikes. The quicker backups can be retrieved, the quicker a business can resume operations. However, too often, businesses don’t check to ensure their backup systems are working as intended or that employees and departments are trained and ready to recover data rapidly.

Microsoft 365 Business Premium also offers IT administrators malware detection, file recovery, and mobile device management, among other critical security applications. Properly configured as part of a comprehensive cybersecurity plan, these applications can help mitigate the risk of ransomware. But it won’t stop criminals from attempting to penetrate your network. Cybersecurity professionals know that the priority is preventing a criminal from successful intrusion and to do so requires the right personnel, processes, and resources. For many businesses, utilizing an MSSP gives them the capacity necessary to prevent the worst possible outcomes.

Employee Training and Awareness

Your employees are your strongest defense, or your weakest link. Human error remains a leading cause of successful cyberattacks. Comprehensive and ongoing security awareness training is paramount:

• Phishing & Social Engineering: Teach employees to recognize suspicious emails, links, and attachments, which are primary vectors for ransomware delivery. Conduct regular simulated phishing exercises to test their vigilance.
• Password Hygiene: Emphasize the importance of strong, unique passwords and the dangers of reusing credentials across multiple platforms.
• Reporting Protocol: Establish clear, easy-to-follow procedures for reporting any suspicious activity, no matter how small it seems. Timely reporting can prevent a minor incident from escalating into a major breach.
• “Think Before You Click”: Instill a culture where skepticism is encouraged, especially regarding unsolicited communications or unusual requests.

Strong Endpoint Protection

Every device connected to your network—laptops, desktops, servers, mobile devices—is a potential entry point for ransomware. Robust endpoint protection is non-negotiable:

• Next-Gen Antivirus (NGAV) & Endpoint Detection and Response (EDR): Move beyond traditional antivirus to solutions that use AI and behavioral analysis to detect and block new and unknown threats in real-time, providing deep visibility into endpoint activity.
• Regular Updates & Patching: Ensure all operating systems, applications, and security software are consistently updated with the latest patches to fix known vulnerabilities that ransomware actors exploit.
• Device Control: Implement policies to restrict the use of unauthorized external devices (USB drives, etc.) that could introduce malware.

The Role of Multi-Factor Authentication (MFA) in Ransomware Prevention

Even if credentials are stolen, MFA acts as a critical second barrier, making it significantly harder for ransomware gangs to gain unauthorized access.

• How it Works: MFA requires users to provide two or more verification factors to gain access to an account or system. This typically involves something you know (password), something you have (phone, security token), or something you are (fingerprint, facial scan).
• Blocking Lateral Movement: If an attacker compromises one account, MFA prevents them from using those stolen credentials to move laterally across your network and access other critical systems or deploy ransomware.
• Mandatory for All Critical Systems: Implement MFA for all sensitive accounts, including email, VPNs, cloud services, administrative portals, and network access points. It’s a simple yet incredibly powerful defense.

Robust Backup and Disaster Recovery Plans

When ransomware inevitably strikes, your ability to recover clean data is your ultimate safeguard against paying the ransom. A comprehensive backup and disaster recovery (BDR) plan is non-negotiable:

• 3-2-1 Backup Rule: Implement the golden rule: at least 3 copies of your data, stored on 2 different media types, with 1 copy off-site (cloud or physically separate location).
• Immutable Backups: Utilize backup solutions that offer “immutability” or “air-gapped” backups, meaning the backups cannot be altered, encrypted, or deleted by ransomware, even if your primary network is compromised.
• Regular Testing: Backups are only useful if they work. Conduct frequent, simulated recovery tests to ensure your data can be restored quickly and accurately, minimizing downtime.
• Versioning: Maintain multiple versions of your backups, allowing you to roll back to a point in time before the infection occurred.

Why Cloud Backups are Essential for Ransomware Recovery

While local backups are good, cloud backups offer unique advantages that are absolutely essential in a ransomware scenario:

• Air-Gapped Protection: Cloud backups, especially those configured correctly, provide an “air gap” – a logical or physical separation from your primary network. This means if ransomware encrypts your on-premises systems, it cannot reach and encrypt your cloud-based backups.
• Geographic Redundancy: Cloud providers typically store your data across multiple geographically diverse data centers. This protects your data not just from cyberattacks, but also from localized disasters like fires or floods.
• Scalability & Accessibility: Cloud solutions scale easily with your data growth and allow for fast recovery from anywhere with an internet connection, ensuring business continuity even if your physical location is compromised.
• Cost-Effectiveness: For many small to medium-sized businesses, cloud backup eliminates the need for expensive on-premises hardware and maintenance.

Combining local and immutable cloud backups offers the most resilient defense against ransomware data loss.

Network Segmentation and Access Controls

Limit the damage of a breach by segmenting your network and controlling who can access what.

• Network Segmentation: Divide your network into smaller, isolated segments. If ransomware infiltrates one segment, it’s contained and prevented from spreading rapidly across your entire infrastructure. Separate critical data, financial systems, and general user networks.
• Least Privilege Access: Grant users and systems only the minimum permissions necessary to perform their tasks. This limits an attacker’s ability to move laterally and elevate privileges if they compromise a single account.
• Regular Audits: Periodically review access rights and network configurations to ensure they align with your security policies and remove any unnecessary permissions.

Email and Web Security Measures

Email and malicious websites are primary entry points for ransomware. Robust security at these layers is crucial.

• Advanced Email Filtering: Implement solutions that use AI and machine learning to detect and block sophisticated phishing attempts, malicious attachments, and spam before they reach user inboxes.
• Web Content Filtering: Control access to known malicious websites and categorize risky web content, preventing employees from inadvertently downloading malware.
• Sandboxing: Utilize sandboxing technology that executes suspicious attachments or links in an isolated, secure environment to detect malicious behavior before it can impact your network.

Patch Management and Vulnerability Remediation

Unpatched software is a wide-open door for ransomware. A rigorous patch management strategy is fundamental.

• Automated Patching: Implement automated systems to ensure operating systems, applications, and firmware are regularly updated across all devices.
• Prioritized Remediation: Not all vulnerabilities are equal. Prioritize patching critical vulnerabilities that are actively being exploited by ransomware groups.
• Regular Vulnerability Scans: Conduct regular scans to identify and remediate weaknesses in your network and systems before attackers can exploit them.

Threat Intelligence and Monitoring

Stay ahead of emerging threats by actively monitoring your environment and leveraging external intelligence.

• Security Information and Event Management (SIEM): Implement SIEM solutions to collect and analyze security logs from across your network, enabling rapid detection of suspicious activities that could indicate an impending or active ransomware attack.
• Endpoint Detection and Response (EDR): As mentioned earlier, EDR tools provide deep visibility into endpoint activities, allowing for proactive threat hunting and rapid response to suspicious behavior.
• Stay Informed: Subscribe to threat intelligence feeds, cybersecurity news, and industry alerts to understand the latest ransomware tactics, techniques, and procedures (TTPs) being used by cybercriminals.

Understanding Double and Triple Extortion Tactics

Modern ransomware isn’t just about encrypting data. Attackers have evolved their tactics to maximize their leverage and profit:

• Double Extortion: Before encrypting your data, attackers first steal a copy of it. If you refuse to pay the ransom for decryption, they threaten to publish or sell your sensitive information (customer data, intellectual property, financial records) on the dark web, adding a severe reputational and legal threat.
• Triple Extortion: Taking it a step further, triple extortion involves attacking multiple parties associated with the victim. This could include notifying customers, partners, or even the media about the breach, or launching DDoS attacks against the victim’s website alongside data encryption and exfiltration, applying immense pressure to pay.

These tactics highlight that merely having backups isn’t enough; robust data loss prevention and incident response planning are crucial.

Incident Response Planning

Despite your best efforts, a ransomware attack can still occur. A well-defined incident response plan is your blueprint for minimizing damage and ensuring a swift recovery.

• Pre-Attack Preparation:
  • Designated Team: Identify a clear incident response team with defined roles and responsibilities (IT, legal, PR, leadership).
  • Communication Plan: Establish internal and external communication protocols for various scenarios.
  • Offline Contact List: Keep essential contacts (legal counsel, cybersecurity experts, law enforcement) accessible offline.
• During the Attack:
  • Containment: Immediately isolate infected systems to prevent spread. Disconnect from networks.
  • Assessment: Determine the scope of the breach and identify the strain of ransomware.
  • Evidence Collection: Preserve logs and system images for forensic analysis.
• Post-Attack Recovery:
  • Eradication: Remove the ransomware and any persistent threats.
  • Restoration: Restore systems and data from secure, immutable backups.
  • Post-Mortem Analysis: Conduct a thorough review to understand how the attack occurred and implement stronger defenses.
• Regular Drills: Conduct regular tabletop exercises and simulations to test your plan, identify gaps, and ensure your team is ready when crisis strikes.

What to Do Immediately After a Suspected Ransomware Attack

Time is of the essence when ransomware is suspected. Every minute counts to contain the damage and protect your business:

1. Isolate Affected Systems IMMEDIATELY: Disconnect any compromised computers or servers from the network. This is the single most critical step to prevent the ransomware from spreading laterally.
2. Activate Your Incident Response Plan: Refer to your pre-defined plan. Notify your designated incident response team and key stakeholders.
3. DO NOT Pay the Ransom (Initially): While tempting, paying the ransom does not guarantee data recovery and often funds future criminal activity. Focus on your recovery plan first.
4. Preserve Evidence: Do not wipe or reformat affected machines immediately. Forensic analysis of compromised systems can provide crucial insights into how the attack occurred.
5. Notify Key Stakeholders: Inform legal counsel, cybersecurity experts (like GiaSpace), and potentially law enforcement.
6. Assess Damage and Identify Point of Entry: Work with IT experts to understand the scope of the attack and how the ransomware gained access.
7. Initiate Recovery from Backups: Begin the process of restoring your data and systems from your clean, immutable backups.
