Ransomware Attack Statistics: What You Need to Know

Ransomware in 2025

• 2025 attacks = bolder, smarter, costlier than ever.
• Threat actors evolve faster than most defenses.
• Victims: businesses, hospitals, governments no sector safe.
• Tactics: double extortion, AI-powered phishing, supply chain hits.
• This report: 2025 stats, actor profiles, attack trends & defenses.
• Goal: help leaders stay ahead & avoid breach headlines.

Quick Takeaways

• Ransomware attacks are up across nearly every sector.
• Recovery times are longer, ransom demands are bigger.
• Groups like Qilin, Akira, and Medusa are dominating the scene.
• Healthcare, education, finance, and legal sectors are prime ransomware targets.
• QR phishing and AIgenerated deepfakes are rising fast.
• Cyber insurance is getting stricter except for higher costs and tighter terms.

Ransomware in 2025: A New Era of Sophistication

Here’s the deal: ransomware attacks aren’t just about locking files anymore. They’re calculated, layered, and designed to exfiltrate before encrypting. Attackers are smarter. Defenders have to be, too.

Groups like Qilin, Akira, and Medusa are blending double extortion, stealthy infiltration, and industry specific targeting. Qilin loves remote access exploits. Akira is going hard after school and college. Medusa? It’s wreaking havoc in the finance world.

Real Example: In Q1 2025, Qilin breached a European investment bank using a VPN zero day. Before encrypting anything, it exfiltrated over 600GB of sensitive data, including unannounced mergers.

The Numbers That Matter in 2025

Let’s break down what the ransomware statistics 2025 are showing us:

• Healthcare attacks: Up 45% hospitals remain a top target.
• Education sector: 30% rise in ransomware cases.
• Finance: 25% increase in targeted incidents.
• Average ransom demand: Now over $1.2 million per case.
• Average payment: $250,000 and that’s just the starting point.
• Average downtime per attack: About 30 days.
• Data exfiltration before encryption: Over 500GB per breach on average.

From our internal telemetry at DeepStrike, we've also seen:

• 1 in 4 ransomware attacks now involve initial access brokers selling credentials.
• 72% of successful breaches began with a phishing email.
• 83% of clients without segmentation experienced lateral movement across networks.

Who’s Getting Hit: Sector Breakdown

Healthcare

Patient data is gold. Attackers know hospitals can’t afford downtime, so they pay faster. Attacks in 2025 have halted surgeries, locked out patient records, and delayed ambulance routing.

Case: A regional medical center in the Midwest had to reroute emergency patients after Medusa encrypted its radiology systems and stole 1.2TB of diagnostic data.

Education

Universities and schools are easy targets: outdated tech, limited budgets, and loads of personal info. Remote learning widened the attack surface. Akira has heavily targeted higher education institutions in North America and Europe.

Finance & Legal

These sectors handle highvalue, sensitive data. A breach doesn’t just cost moneyit can lead to regulatory fines and lawsuits. Medusa and Hellcat are hitting them hard.

CISO Tip: “Legal firms are especially vulnerable. One stolen NDA or contract can cost more than the ransom itself.”

Top Ransomware Attack Vectors

Phishing Is Evolving

Forget typos and bad grammar. In 2025, phishing attacks are:

• AI generated emails that mimic company tone.
• Deepfake voice calls impersonating execs.
• Malicious QR codes (aka quishing)a major trend this year.

Underground forums now sell ChatGPTstyle tools that generate custom phishing lures in under 60 seconds.

Remote Access Vulnerabilities

RDP, VPNs, and outdated third party software are still being exploited daily.

Quick tip: No MFA + no patching = open invitation for ransomware.

Most Active Ransomware Groups in 2025

The Big 3

• Qilin: Precision targeting, advanced evasion, huge data grabs.
• Akira: Brutal double extortion tactics on schools and SMBs.
• Medusa: High profile targets in finance and critical infrastructure.

Rising Threat Actors

• Hellcat: Legal and government sectors beware.
• RansomHub: Zeroday exploit arsenal and fast deployment.
• NightSpire: Custom payloads aimed at critical systems.

Real Case: In March 2025, NightSpire disabled a Southeast Asian energy provider’s control systems for 18 days after demanding $8 million in crypto.

The Economics of Ransomware in 2025

• 60% of victims now file cyber insurance claims post breach.
• Average cost of recovery (ransom, downtime, legal, reputation): $4.54 million.
• Insurance premiums are skyrocketing. Many insurers are cutting coverage.

Reality Check: Insurance is a backup not your cybersecurity plan.

Quick Ransomware Readiness Checklist

Ask yourself:

• Tested backups in the last 30 days?
• Quarterly phishing simulations?
• MFA enforced on all remote access points?
• Network segmented by role/department?
• Annual (or more frequent) penetration tests?

If you said “no” to more than one… you’ve got work to do.

What You Should Do Right Now

1. Run Penetration Tests (Seriously)

Simulate real attacks. Test external and internal surfaces. Don’t guesstest. More on penetration testing.

2. Train Your Team

Phishing drills, awareness campaigns, and fast reporting culture. Phishing statistics 2025.

3. Lock Down Remote Access

Disable unused ports. Enforce MFA. Use allowlisting.

4. Segment the Network

Separate sensitive systems. One infected workstation shouldn’t bring down your whole org.

5. Test Your Backups

Don’t just back up the test. Store offline copies. Encrypt backups.

3 Red Flags You’re RansomwareReady (For All the Wrong Reasons)

1. Still clicking sketchy links with no training plan.
2. Using a 2019 firewall, no updates, no logs.
3. One shared password for all vendor logins you know who you are.

Legal and Regulatory Shakeups

Governments aren’t playing around anymore:

• 72hour breach reporting is now mandatory in the U.S. and EU.
• Fines and penalties for lax cybersecurity controls.
• New grant funding for small businesses improving cyber hygiene.

Quick Tip: Regulatory compliance = stronger security posture.

Looking Ahead: What to Expect in 2026

• Expect more AIdriven phishing.
• More ransomware as a service affiliates.
• Insurance claims will get more restrictive.
• Crossborder attacks will increase as global tensions rise.

Now’s the time to harden your defenses before 2026 hits harder.

Final Thoughts: Get Proactive or Get Compromised

Ransomware isn’t a “maybe.” It’s happening now. Every day. And it’s more targeted than ever.

But here’s the good news: defenders can win. With the right tools, training, and awareness, you can stay ahead.

Real security isn’t about fear. It’s about preparation, resilience, and action.
