Ransomware is like a burglar who keeps upgrading their tools — picking smarter locks and finding new ways to slip inside unnoticed. In 2025, these digital burglars will be more sophisticated than ever, using tactics like artificial intelligence and double extortion to cause maximum damage.

Staying ahead of these tactics starts with understanding them. This post breaks down the latest ransomware strategies and provides practical tips to help protect your business in this ever-changing landscape.

What Makes Ransomware Different in 2025?

Ransomware in 2025 will be smarter and more targeted than ever before. For instance, Google’s research points to the rise of AI. Cybercriminals use AI to craft convincing phishing emails and deploy malware that adapts to evade detection. This makes attacks more challenging to spot and easier to execute.

Double extortion has cemented itself as a leading tactic. Attackers encrypt data and simultaneously exfiltrate it, threatening to leak sensitive information unless their demands are met. This combination significantly raises the stakes for victims, exposing them to financial, reputational, and regulatory risks. By late 2022, 70% of ransomware incidents involved data theft. That statistic has only continued to rise since then.

Small to medium-sized businesses (SMBs) are increasingly in the crosshairs. With fewer resources for cybersecurity, SMBs suffer cyber extortion attacks 4.2 times more often than larger enterprises. Follow the guidance below to avoid becoming their next target.

Trending Tactics Cybercriminals Use

Cybercriminals constantly refine their methods and utilize new technologies and strategies to maximize their impact. Here are some of the most dangerous ransomware tactics emerging in 2025:

AI-Driven Phishing Emails

Attackers leverage artificial intelligence to craft phishing emails en masse, that are increasingly difficult to distinguish from genuine communications. These emails can mimic trusted contacts, including coworkers or service providers, and are personalized to increase their effectiveness.

Exploitation of Remote Work Vulnerabilities

The rise of hybrid and remote work environments has provided cybercriminals with new attack surfaces. Home office setups often lack enterprise-grade security measures, and unsecured personal devices or outdated VPN configurations make them easy entry points. Once inside, attackers can move laterally to access critical business systems.

Ransomware-as-a-Service (RaaS)

RaaS has democratized ransomware operations, enabling even low-skill attackers to launch sophisticated campaigns. Through this model, cybercriminals purchase or lease ready-made ransomware tools from other threat actors acting as “service providers.” This reduces the barrier to entry significantly, and therefore makes it increasingly likely that businesses that would have previously been too low-profile to be at high risk will be targeted.

What You Can Do to Stay Secure

Ransomware is evolving, but taking proactive steps can keep businesses ahead of the threats. These include:

Spot Suspicious Emails

Phishing emails are still the most common entry point for ransomware. Verify links and attachments before clicking and watch for red flags like mismatched sender details or unusual requests. If something feels off, reach out to the sender directly using a known contact method.

Use Multi-Factor Authentication (MFA)

MFA adds a critical layer of protection by requiring a second step, like a code sent to your phone, before granting access. Even if passwords are compromised, MFA can block unauthorized logins and secure sensitive systems.

Train Your Team

Employees are your first line of defense. Regular training helps them recognize phishing attempts, avoid clicking on malicious links, and report suspicious activity. Awareness across your team significantly reduces your vulnerability.

If you have a Security Awareness Training program, make sure to emphasize training compliance with your team. We recommend all employees take a Security Awareness Training course in their first week of employment, and then refresh the training at least annually. Leadership should lead by example, and take steps to ensure the whole team completes training within the targeted window.

If you don’t currently have a Security Awareness Training program, consider implementing one ASAP. Make sure to require all current employees to take the training, as well as to incorporate the training into your new employee onboarding materials to ensure ongoing compliance.

Implement Workstation Access Management

Employee end-users often need to be able to install or update approved software, but should be blocked from installing software or changing system settings that could put your business at risk (whether directly or via a threat actor). With the right Workstation Access Managment tools and policies in place, threat actors can often be stopped in their tracks even when other methods fail. Green Loop IT Solutions can help small to medium-sized businesses strengthen their defense-in-depth by establishing and enforcing controls on whether employees can install unapproved software on their workstations. Whether you decide to allow or block installations, we ensure the policy is tailored to meet your business’s specific needs and security objectives.

Staying Ahead in the Fight Against Ransomware

Ransomware is not going away—it’s evolving, growing smarter, and becoming a greater threat to businesses of all sizes. The key to resilience lies in staying informed, proactive, and adaptable. By understanding emerging tactics, you can take the necessary steps to strengthen your defenses.
