At present, ransomware is one of the most disruptive and costly types of cyberattacks that businesses have to face. Ransomware attacks can lock users out of vital files or systems and may demand payment, often paid using cryptocurrency, in order to regain access to them. Over the years, cybercriminals have developed and mastered new techniques for creating more advanced versions of ransomware, making it more difficult for organizations to uncover them or to evade their attacks.
As of 2025, ransomware incidents continued to rise sharply, with cybercriminals targeting organizations of all sizes; thousands of organizations were actively engaged in ransomware incidents in 2025. Understanding the evolving trends in ransomware will be crucial for businesses looking for effective cybersecurity solutions.
In 2025, ransomware attacks are predicted to increase by 34–58% compared to prior periods. The majority of these attacks will be focused on critical industries such as manufacturing, healthcare, energy, and finance; these four sectors accounted for nearly half of all ransomware incidents in 2025. Cybercriminal groups such as Qilin, SafePay, Akira, and DragonForce were among those leading the way in ransomware attacks; they often use methods such as taking advantage of known vulnerabilities or stealing user credentials to obtain initial access.
Ransomware has changed significantly over the past few years. The most significant is the introduction of double-extortion tactics. Attackers use double extortion by first stealing sensitive files from their victims and only then encrypting them; unless you pay the ransom demanded, the attackers threaten to release the stolen information publicly. By implementing double-extortion tactics, attackers gain significant leverage over their victims. Even if they successfully restore their files from backup, their files can still be subject to public distribution.
Due to this, some attackers are trying to escalate their tactics to triple- and quadruple-extortion tactics, such as threatening to contact the victims' customers or regulators.
Throughout the last few months, there have been many headlines in the news that speak to the damages associated with these types of attacks on many health care providers. Several hospitals and medical clinics were victims of ransomware attacks, and hundreds of thousands of patients had their personal and/or medical records compromised.
Several automotive and retail companies are suffering from multi-million-dollar losses as a direct result of ransom payments as well as the lost revenue due to the downtime associated with the attacks.
Not only are ransomware attacks not limited to large corporations, but they also can have a negative financial impact on organizations of any size. Furthermore, the financial impact of ransomware will extend beyond the ransom demand, as the organization will incur expenses associated with prolonged outages, legal expenses, and damage to their long-term reputation.
There are many factors contributing to the sustained success of ransomware and its growth. Attackers use a variety of methods to execute their attacks on organizations, with phishing e-mails being the primary method, as most employees will click on phishing e-mails that contain a link and/or attachment(s).
Attackers can also utilize:
Attackers typically progress laterally within a computer system, gaining entry into many different systems, deactivating any necessary security measures that are in place, and removing backup systems from accessibility to halt the ability of an infected organization to recover from ransomware quickly.
The emergence of Ransomware as a Service (RaaS) (e.g., "Robo Ransomware," "Ransomware-as-a-Service") has lowered the hurdle to place and run a professional-quality ransomware attack, and criminals with lower skill levels can now easily achieve this level of sophistication.
Ransomware prevention strategies should include a multi-layered (or "defense-in-depth") approach that combines technology, people, and processes. Organizations should consider the following best practices to minimize the risk of falling victim to ransomware:
1. Implement Effective Backup and Restore Strategies
The most effective way to defend yourself against ransomware is to back up your organization's vital data regularly. To maximize your backup strategy, you should consider the "3-2-1 rule." This rule states that you need three copies of your data on two different mediums, and the third copy must be stored either in an external location or in the cloud storage service, which has "immutable" storage capabilities.
Testing that your backups can be restored quickly and completely is vital. Having immutable backup capabilities will help prevent cybercriminals from destroying or corrupting your backups with their attacks.
2. Keep All Software Up-To-Date and Patch Vulnerabilities Quickly
Outdated software is an easy entry point for cybercriminals to gain access to a system. Patching your organization's operating system, application, browser, and networking hardware should be a priority within your organization. As part of your organization's patching and update strategy, it is essential to prioritize and patch vulnerabilities that are currently being exploited by cybercriminals.
3. Access Controls Are Very Important
When possible, use Multi-Factor Bio-Metrics, User and Password, to log into accounts that support that option as well as remote access to corporate systems. Utilize the Least Privilege Option to limit what users and systems can access. Also, apply a Zero Trust Architecture by ensuring that no user or device is trusted by default.
4. Segment Your Network to Find Threats
By segmenting your networks into separate (isolated) networks and ensuring that if one is breached, the attacker or threat cannot spread easily to your critical systems, backup, or sensitive data.
5. Train Your Employees Regularly
Most cyber-attack incidents happen due to human error. Conduct regular cybersecurity awareness training targeted at teaching employees how to identify phishing, unsafe links, and safe cybersecurity practices. Create cybersecurity simulation activities using both passive and active types of cyber-attacks to reinforce the training and build a cybersecurity culture.
6. Deploy Advanced Security Solutions
Use Endpoint Detection and Response (EDR) solutions, next-generation firewalls, and artificial intelligence (AI) to detect threats. In addition, email security gateways will block malicious attachments or links before they reach users.
7. Have a Plan: Develop and Test Your Response to Cyber-Attacks
Ensure you have a plan for detection, containment, and recovery from cyber-attacks. Have procedures to communicate, assign roles to team members, and activate the involvement of law enforcement or cybersecurity professionals. Conduct regular tabletop exercises to ensure all team members know what to do.
8. Monitoring and Responding to Emerging Cyber Risks
Continuously monitor for unusual activity and have processes in place to determine when an attack is happening and to respond immediately.
Ransomware has been and will continue to be one of the most financially lucrative industries for cybercriminals. Organizations that view cybersecurity as a top priority can greatly reduce their overall risk by taking the following measures:
Preparedness is about much more than just defending against a successful cyber attack; it is also about how to respond quickly and effectively if you do fall victim to one. Resiliency, which is defined as taking proactive measures to minimise the impact of future attacks, is increasingly becoming the primary mechanism for protecting against double-extortion ransomware and other ever-evolving cyberthreats.
To protect your organisation from an ever-evolving cyberthreat environment, you must stay up-to-date on current threats and act quickly while also creating a culture of secured, responsible behaviours within your organisation. The cost of preparing for and creating the opportunity for prevention will always be significantly lower than the monetary costs of recovering from a successful ransomware attack.
