The State of Ransomware in 2024
Ransomware Statistics
Ransomware continues to be a growing concern for organizations worldwide. In 2024, the average ransom demanded reached a staggering $2.73 million, a significant jump from 2023. Despite the rising costs, 97 percent of organizations whose data was encrypted during an attack were able to recover it.
However, the recovery process can be time-consuming and costly. On average, companies affected by ransomware experienced 24 days of downtime, severely disrupting business operations. In terms of attack prevalence, ransomware incidents have risen by 13% over the past five years, with 2023 seeing an average cost of $1.85 million per incident. The U.S. remains a major target, accounting for nearly half of global ransomware attacks in 2023.
Ransomware Attack Trends
One major trend in ransomware attacks is the growing focus on managed service providers (MSPs). By targeting MSPs, attackers can gain access to multiple organizations simultaneously, as MSPs manage IT services for numerous clients. Once a hacker breaches an MSP, they can move laterally to exploit the MSP’s entire client base.
Ransomware attackers have also shifted their focus to industries most vulnerable due to economic pressures, such as healthcare, education, and municipalities. The increase in remote work has provided hackers with more opportunities to exploit security gaps, particularly when employees use personal devices with weaker protections. Attackers are also increasingly leveraging ransomware-as-a-service (RaaS) models to extend their reach.
- Implement behavioral analysis for detection: Use advanced security solutions that employ behavioral analysis to detect anomalous activities that could indicate a ransomware attack. This helps in identifying new and unknown ransomware strains that traditional signature-based methods might miss.
- Establish a robust incident response plan: Create and regularly update a detailed incident response plan that outlines the steps to take when a ransomware attack is detected. This plan should include communication protocols, roles and responsibilities, and recovery procedures.
- Conduct regular red team exercises: Engage in regular red team exercises where security experts simulate ransomware attacks on your infrastructure. This practice helps in identifying vulnerabilities and improving your defensive measures.
- Use deception technology: Deploy deception technology, such as honeypots and decoys, to detect and mislead attackers. This technology creates fake environments and data that appear legitimate, enticing ransomware to reveal itself and allowing security teams to respond before real damage occurs.
- Enforce strict application control: Use application control measures to allow only whitelisted applications to run on your systems. This prevents unauthorized and potentially malicious software from executing.
11 Ways to Prevent Ransomware Attacks
1. Practice Good IT Hygiene
Maintaining good IT hygiene is essential for protecting against ransomware. This involves implementing regular practices to ensure systems are secure and up-to-date. Regularly patching and updating all software and operating systems is critical as it fixes known vulnerabilities that ransomware can exploit.
Establishing strong password policies, such as requiring complex passwords and enforcing multi-factor authentication (MFA), helps protect accounts from unauthorized access. Regularly auditing user accounts and removing outdated access permissions further reduces potential entry points for attackers. Additionally, conducting routine security assessments and vulnerability scans can identify and address potential weaknesses in the IT infrastructure.
2. Improve Resiliency of Internet-facing Applications
Internet-facing applications are particularly vulnerable to ransomware attacks. Improving their resiliency involves adopting secure coding practices during development to minimize vulnerabilities. Regularly scanning these applications for security flaws and promptly applying patches can prevent exploitation.
Implementing web application firewalls (WAFs) adds an additional layer of security by filtering out malicious traffic and preventing attacks like SQL injection and cross-site scripting (XSS). Additionally, organizations should conduct regular penetration testing to identify and mitigate vulnerabilities before they can be exploited by attackers. Continuous monitoring and logging of application activities can also help in early detection of suspicious behaviors.
3. Address Infection Vectors
Ransomware often infiltrates systems through common infection vectors such as phishing emails, malicious websites, and infected USB drives.
To mitigate these risks, organizations should implement robust email filtering solutions that detect and block phishing attempts and malicious attachments. Using DNS filtering to prevent access to known malicious websites can also reduce the risk of drive-by downloads. Disabling auto-run features for USB drives and other removable media can prevent malware from executing automatically when such devices are connected.
4. Implement Immutable Backups
Implementing immutable backups is a critical step in protecting data from ransomware attacks. Immutable backups are designed to be unchangeable, ensuring that once data is written, it cannot be altered or deleted. This is achieved through write-once-read-many (WORM) technology, which prevents any modifications after the data is initially recorded.
✅ Pro Tip: N2W facilitates automated, immutable backup creation and secure data storage on AWS.
By utilizing immutable backups, organizations can guarantee the integrity and availability of their data even if ransomware encrypts or corrupts the primary data sources. Incorporating immutable backups into a broader backup strategy involves regularly scheduling backups, testing restore procedures, and keeping multiple copies of critical data in different locations.
Organizations should ensure that backup solutions support immutability and can integrate with existing IT infrastructure. Furthermore, it is essential to monitor and manage backup processes to quickly detect and resolve any issues that might compromise backup integrity.

5. Keep Backup Snapshots of Cloud Resources
Cloud environments are increasingly targeted by ransomware due to their critical role in business operations. Regularly taking snapshots of cloud instances, databases, and storage systems ensures that recent, clean versions of data are available for restoration in the event of an attack.
Organizations should automate the creation of these snapshots, scheduling them at frequent intervals to minimize data loss. It is also important to store these snapshots in separate, secure locations, such as different cloud regions or external backup services, to protect against simultaneous compromise. Implementing access controls and encryption for these backup snapshots further enhances security.
✅ Pro Tip: With N2W, you can schedule and securely store snapshots in isolated regions. You can also automate cross-region replication, further protecting against localized attacks or accidental deletions.
6. Protect Network Perimeter and Implement Network Segmentation
Almost all ransomware attacks penetrate an organization’s systems via the network. To protect against external threats, use firewalls to block unauthorized access and deploy intrusion detection and prevention systems (IDPS) to identify and mitigate threats. Additionally, use security information and event management (SIEM) systems for continuous monitoring.
In addition, network segmentation is a crucial practice for limiting the spread of ransomware within a network. This involves dividing a network into smaller, isolated segments to contain infections and prevent lateral movement by attackers. By separating critical systems and sensitive data from other parts of the network, organizations can ensure that even if one segment is compromised, others remain secure.
Implementing VLANs (Virtual Local Area Networks) and setting up proper access controls helps enforce this separation. Additionally, deploying firewalls and access control lists (ACLs) between network segments can further restrict unauthorized access and enhance security.
7. Implement a Zero Trust Architecture
A zero trust architecture (ZTA) operates on the principle of “never trust, always verify.” This approach requires strict identity verification for every person and device attempting to access resources, regardless of their location. Implementing ZTA involves continuous monitoring and validation of user and device identities, using multi-factor authentication (MFA), and applying least-privilege access policies to minimize the potential impact of compromised accounts.
Organizations should segment networks to isolate critical systems and data, and enforce strict access controls to ensure only authorized users can access sensitive resources. Additionally, leveraging advanced threat detection and response capabilities can help identify and mitigate potential threats in real-time, enhancing the overall security posture.
8. Implement and Enhance Email Security
Email is a common vector for ransomware distribution, making enhanced email security crucial. Deploying advanced email filtering and scanning solutions can detect and block malicious attachments and links. Implementing DMARC (Domain-based Message Authentication, Reporting & Conformance), SPF (Sender Policy Framework), and DKIM (DomainKeys Identified Mail) helps prevent email spoofing and ensures the authenticity of incoming emails.
Additionally, educating employees on recognizing phishing emails and avoiding suspicious links is vital. Organizations should also consider implementing email encryption to protect sensitive information and using sandboxing techniques to analyze suspicious email attachments in a controlled environment before they can cause harm.
9. Harden Your Endpoints
Endpoint hardening involves securing all devices connected to the network, including computers, mobile devices, and servers. This can be achieved by configuring devices with the least-privilege access, applying security patches regularly, and using endpoint detection and response (EDR) solutions to monitor and respond to threats.
Disabling unnecessary services and ports on endpoints reduces the attack surface and limits potential entry points for ransomware. Additionally, implementing application whitelisting can prevent unauthorized software from executing on endpoints. Regularly updating antivirus and anti-malware software ensures protection against the latest threats.
10. Implement a Comprehensive Cybersecurity Training Program
A comprehensive cybersecurity training program is essential for educating employees about the latest threats and safe practices. Regular training sessions should cover topics like recognizing phishing emails, safe internet usage, proper handling of sensitive data, and responding to potential security incidents.
Encouraging a security-aware culture ensures that employees are vigilant and act as the first line of defense against ransomware attacks. Incorporating simulated phishing exercises can help employees recognize and respond to real threats more effectively. Providing ongoing education and updates on emerging threats and security best practices ensures that employees remain informed and prepared to mitigate potential risks.
11. Regularly Test Data Restoration
Testing data restoration processes is essential to ensure that backups are reliable and can be quickly recovered in case of a ransomware attack. Schedule periodic restoration tests to confirm that data can be accessed within the required timeframes and meets recovery objectives.
✅ Pro Tip: Using solutions like N2W Backup & Recovery, you can simplify the testing process by restoring backups across various AWS regions and accounts, when simulating real recovery scenarios. This practice helps identify any potential issues before an actual attack occurs, ensuring minimal downtime and business continuity.
