The Ransomware Epidemic Is Already Here

When someone searches for ransomware examples — whether they're typing "2026" or any other year — they're really asking one question: what does a real ransomware attack look like, and how do I stop it from happening to me? I've spent years watching these attacks evolve, and I can tell you this: the tactics threat actors use today will still be the playbook for years to come. The patterns are already set.

In 2020, ransomware payments exceeded $350 million in cryptocurrency — a 311% increase over the previous year, according to Chainalysis. The FBI's Internet Crime Complaint Center (IC3) received 2,474 ransomware complaints in 2020 alone. And that number drastically undercounts the real total because most victims never report.

This post breaks down real ransomware examples from the past two years, explains exactly how they worked, and gives you specific steps to protect your organization right now — and for years ahead.

What Makes Ransomware So Effective in the Real World

Ransomware isn't sophisticated because of its encryption. AES-256 has been around for decades. What makes it devastating is the delivery mechanism — and that's almost always a human being clicking something they shouldn't.

The Cybersecurity and Infrastructure Security Agency (CISA) consistently identifies phishing emails as the number-one initial access vector for ransomware. Credential theft, exposed Remote Desktop Protocol (RDP) ports, and unpatched VPN appliances round out the top four. Every ransomware example I'll walk through below exploited at least one of these entry points.

Here's what I tell every organization I work with: ransomware is a people problem wrapped in a technology wrapper. If your employees can spot a phishing email, your risk drops dramatically. That's why investing in cybersecurity awareness training is the single highest-ROI security decision you can make.

Ryuk: The Ransomware That Shut Down Hospitals During a Pandemic

In October 2020, the FBI, CISA, and the Department of Health and Human Services issued a joint advisory warning of an imminent Ryuk ransomware threat targeting U.S. hospitals. It wasn't hypothetical. Universal Health Services (UHS), which operates over 400 facilities, suffered a Ryuk attack in September 2020 that forced staff to use pen and paper for weeks.

UHS estimated the attack cost them $67 million in lost revenue and remediation. The initial access? A phishing email carrying a Emotet/TrickBot payload that eventually deployed Ryuk.

How Ryuk Actually Works

Ryuk follows a multi-stage attack chain that's become a template for modern ransomware:

  • Stage 1: A phishing email delivers Emotet or BazarLoader malware.
  • Stage 2: The initial malware downloads TrickBot, which maps the network, harvests credentials, and identifies high-value targets.
  • Stage 3: After days or weeks of reconnaissance, the threat actor deploys Ryuk across the network, encrypting everything simultaneously.
  • Stage 4: Ransom demand — typically in Bitcoin, often seven figures.

The dwell time between initial compromise and ransomware deployment is what makes Ryuk so damaging. By the time you see the ransom note, the attacker has been inside your network for weeks.

Maze and the Birth of Double Extortion

Before Maze, ransomware was straightforward: encrypt data, demand payment, maybe give back the decryption key. Maze changed everything in late 2019 by stealing data before encrypting it, then threatening to publish it if the victim didn't pay.

Allied Universal, a major security staffing firm, was one of Maze's early high-profile victims. When they didn't pay, the Maze operators leaked 700 MB of stolen data online. This double extortion tactic became the industry standard almost overnight.

Why Double Extortion Changes Your Risk Calculus

If you thought backups alone protected you from ransomware, Maze proved otherwise. Even with perfect backups and a fast recovery, your sensitive data is now in a threat actor's hands. That means potential regulatory fines, customer notification costs, lawsuits, and brand damage.

This is why a zero trust security model matters. Segmenting your network, enforcing least-privilege access, and monitoring lateral movement can limit what an attacker can steal — even after initial compromise.

REvil (Sodinokibi): Ransomware-as-a-Service at Scale

REvil, also known as Sodinokibi, operates as a ransomware-as-a-service (RaaS) platform. The developers build and maintain the ransomware; affiliates carry out the attacks and split the ransom payments. It's a franchise model for cybercrime.

In March 2021, REvil hit Acer with a $50 million ransom demand — the largest publicly known demand at the time. They exploited a Microsoft Exchange vulnerability to gain access. Earlier, in January 2020, Travelex paid a reported $2.3 million ransom to REvil after an attack crippled their foreign currency exchange services globally.

The RaaS Model Means More Attackers, Not Fewer

Here's what keeps me up at night about RaaS: it lowers the barrier to entry. A threat actor doesn't need to write malware anymore. They just need to buy access. The FBI IC3 2020 Internet Crime Report highlighted how this affiliate model is accelerating the volume of attacks across every industry.

Your organization doesn't need to be a Fortune 500 target. REvil affiliates go after mid-market companies, law firms, manufacturing plants — anyone with data worth encrypting and insurance policies worth exploiting.

Ransomware Examples: What Do They All Have in Common?

Every major ransomware example from the past two years shares a remarkably consistent attack pattern:

  • Initial access through phishing or credential theft — over 90% of the time, according to the Verizon 2020 Data Breach Investigations Report.
  • Lateral movement using stolen credentials — attackers don't stay where they land. They move to domain controllers, file servers, and backup systems.
  • Dwell time measured in days to weeks — the ransomware payload is the last step, not the first.
  • Targeting of backups — modern ransomware specifically seeks out and destroys backup copies before encrypting production data.
  • Double extortion as standard practice — data exfiltration before encryption is now the norm.

Understanding these patterns is far more valuable than memorizing strain names. The specific malware changes. The methodology doesn't.

How to Actually Defend Against Ransomware in Any Year

I've consulted with organizations after they've been hit. The playbook for prevention is the same whether we're talking about 2021 or years from now. Here's what actually works.

Train Your People Before Threat Actors Train Them for You

Phishing simulations reduce click rates by 60% or more when done consistently. I've seen organizations go from a 35% click rate to under 5% within six months of implementing regular phishing awareness training. That's not a marginal improvement — that's eliminating the primary attack vector for ransomware.

Your employees are either your first line of defense or your biggest vulnerability. There's no middle ground.

Implement Multi-Factor Authentication Everywhere

Credential theft is the second most common ransomware entry point after phishing. Multi-factor authentication (MFA) neutralizes stolen passwords. Deploy it on email, VPN, RDP, cloud services — everything externally accessible. No exceptions.

Segment Your Network and Enforce Least Privilege

If every user and system has access to everything, one compromised account means total encryption. Network segmentation limits blast radius. Least-privilege access means your accounting clerk's credentials can't be used to reach your domain controller.

Patch Aggressively, Especially Edge Devices

REvil exploited Microsoft Exchange vulnerabilities. Other ransomware groups have exploited Pulse Secure VPN, Citrix ADC, and Fortinet VPN flaws. CISA maintains a catalog of known exploited vulnerabilities — use it as your priority patching list.

Maintain Offline, Tested Backups

Backups don't help if the ransomware encrypts them too. Follow the 3-2-1 rule: three copies, two different media types, one offline. Test restoration quarterly. I've seen organizations discover their backups were corrupted only after they desperately needed them.

Deploy Endpoint Detection and Response (EDR)

Traditional antivirus won't catch fileless malware or living-off-the-land techniques that modern ransomware operators use. EDR solutions detect behavioral anomalies — like a process encrypting thousands of files per minute — and can isolate endpoints automatically.

What Is the Most Common Way Ransomware Infects an Organization?

Phishing emails are the most common ransomware infection vector, responsible for the initial compromise in the vast majority of ransomware incidents. According to the Verizon 2020 Data Breach Investigations Report, social engineering — primarily phishing — was involved in over 22% of all breaches, and that percentage climbs significantly when looking at ransomware specifically. The second most common entry point is exploitation of exposed RDP services using stolen or brute-forced credentials. Defending against both requires a combination of security awareness training, MFA, and network hardening.

The $67 Million Question

UHS spent $67 million recovering from Ryuk. Travelex paid $2.3 million in ransom and eventually went into administration. Garmin reportedly paid a $10 million ransom after a WastedLocker attack in July 2020 disrupted their services globally.

These aren't abstract numbers. They're real financial consequences that hit real organizations. And in every case, the initial compromise was preventable.

The ransomware examples dominating headlines right now will look familiar five years from now. The strain names will change. The delivery mechanisms will evolve slightly. But the fundamentals — phishing, credential theft, lateral movement, encryption — will remain constant.

Your defense strategy should be equally constant. Train your people with comprehensive security awareness training. Implement technical controls that assume breach. Test your backups. Run phishing simulations until your click rate approaches zero.

Because the question isn't whether a threat actor will target your organization. It's whether your people and your systems are ready when they do.
