How Ransomware Became the Fastest-Growing Cyber Threat
Imagine arriving at work one morning, turning on your computer, and seeing a red screen that says all your files are locked. The message demands $500,000 in Bitcoin within 72 hours or everything will be gone forever. You are not alone. Hospitals, schools, cities, pipelines, and even meat-packing plants have seen the exact same screen. That is ransomware, and in just ten years it went from a rare curiosity to the single biggest cybersecurity nightmare on the planet. In 2013, almost nobody had heard of it. By 2025, it is a multi-billion-dollar criminal industry that shuts down critical services and makes ordinary criminals richer than drug cartels. This blog post explains, in plain English, how ransomware exploded, why it is so hard to stop, and what it means for all of us.

The Early Days: 1989–2012 (Ransomware Was a Joke)
- 1989: The AIDS Trojan mailed on floppy disks asked for $189 by post
- 2005–2012: Fake antivirus scams and simple file lockers demanded $50–$200 via prepaid cards
- Most victims just restored from backups or reformatted their PCs
Back then, ransomware was rare, amateurish, and easy to beat. Few people paid, and criminals made almost no money.
2013: CryptoLocker – The Turning Point
In September 2013, a new ransomware called CryptoLocker appeared. It used strong encryption that nobody could break, and it demanded payment in Bitcoin. Suddenly, paying was the only realistic way to get files back for many victims.
- Used military-grade AES + RSA encryption
- Victims paid an average of $300–$700
- Criminals earned over $3 million in the first few months
- FBI takedown in 2014 (Operation Tovar) came too late – the model was proven
Bitcoin + unbreakable encryption = profit. The ransomware gold rush began.
2016–2017: The Explosion (SamSam, WannaCry, NotPetya)
- 2016: SamSam targets hospitals and cities, manually hacking networks instead of mass email
- May 2017: WannaCry infects 200,000+ computers in 150 countries in one day, including NHS hospitals
- June 2017: NotPetya (disguised as ransomware) wipes companies worldwide, causes $10 billion damage
These attacks showed that ransomware could bring entire countries to a halt. Hospitals turned patients away. Factories stopped. Cities lost 911 services.
2019–2021: Ransomware-as-a-Service and Double Extortion
Criminals turned ransomware into a franchise business:
- Ransomware-as-a-Service (RaaS): Groups like REvil, DarkSide, and Conti sell or rent their malware
- Affiliates do the hacking and split profits (70/30 or 80/20)
- Double extortion: Steal data first, then encrypt – threaten to publish if no payment
- Leak sites appear on the dark web to shame victims
Now anyone with $1,000 and basic skills could run a ransomware attack.
2021–2023: The Billion-Dollar Years
- May 2021: Colonial Pipeline pays $4.4 million, causes fuel shortages on U.S. East Coast
- July 2021: REvil attacks Kaseya – 1,500+ companies hit at once
- 2022: Costa Rica declares national emergency after Conti attack
- 2023: MOVEit supply-chain attack affects millions (British Airways, BBC, governments)
Ransom demands jumped from hundreds of thousands to tens of millions of dollars.
2024–2025: AI, Supply-Chain Attacks, and Nation-State Links
- AI writes perfect phishing emails in any language
- Deepfake voice calls trick employees into running malware
- Attackers target managed service providers to hit thousands at once
- Evidence grows that Russia and North Korea protect or run major groups
Ransomware is no longer just crime. It is economic warfare.
Why Ransomware Grew Faster Than Any Other Threat
- Direct money: Victims pay quickly to survive
- Low risk: Bitcoin + safe countries = almost no arrests
- Easy entry: RaaS lowers the skill barrier
- High success rate: Many organizations still lack backups
- Double/triple extortion increases pressure
- No need to hide: Public shaming works in criminals’ favor
Timeline of Major Ransomware Milestones
| Year | Event | Why It Mattered |
|---|---|---|
| 1989 | AIDS Trojan | First ever ransomware |
| 2013 | CryptoLocker | Proved strong encryption + Bitcoin = profit |
| 2017 | WannaCry & NotPetya | Showed global disruption possible |
| 2019 | REvil, Conti RaaS launch | Ransomware becomes a franchise |
| 2021 | Colonial Pipeline attack | First national infrastructure crisis |
| 2024–2025 | AI + supply-chain focus | Next evolution already here |
Conclusion
In just over a decade, ransomware went from a forgotten 1989 experiment to the fastest-growing and most profitable crime in history. Strong encryption, Bitcoin, and the ransomware-as-a-service model turned it into a perfect business for criminals and a nightmare for everyone else. Hospitals delay surgeries, schools close, fuel runs out, and cities lose emergency services, all because someone clicked the wrong email. The fight is not over. Backups, updates, training, and never paying are still the best defenses we have. Ransomware grew so fast because it works. Until that changes, it will keep growing.
What is ransomware?
Malware that encrypts your files and demands payment (usually Bitcoin) to unlock them.
When did ransomware really start making money?
2013 with CryptoLocker, the first widely successful version.
Why do people pay the ransom?
Because they have no recent backups and need their data to survive.
Should you ever pay ransomware?
Experts say no. It funds crime and there is no guarantee you get your files back.
What is Ransomware-as-a-Service?
A business model where developers rent their ransomware to others for a cut of profits.
What was WannaCry?
A 2017 worm that infected 200,000+ computers worldwide, including UK hospitals.
How much was the biggest ransom paid?
Public reports show payments up to $40–70 million in 2024–2025.
Which group attacked Colonial Pipeline?
DarkSide, a Russia-based ransomware gang.
Why is Bitcoin perfect for ransomware?
It is hard to trace and works across borders.
What is double extortion?
Encrypting files and threatening to publish stolen data if no payment is made.
Can ransomware be stopped with antivirus?
Good antivirus helps, but many attacks now bypass it. Backups are the real lifesaver.
Which countries host most ransomware gangs?
Russia, North Korea, and some Eastern European countries that rarely cooperate with the West.
What happened to REvil and Conti?
Both were disrupted by law enforcement, but members restarted under new names.
How much does ransomware cost the world each year?
Estimates range from $20 billion to over $1 trillion including recovery costs.
Why do hospitals get attacked so often?
They have critical data, old systems, and cannot afford downtime – they pay quickly.
What is the best defense against ransomware?
Regular offline backups, software updates, employee training, and strong email filters.
Is ransomware a national security threat?
Yes. The U.S., EU, and many countries now treat major attacks as potential national emergencies.
Will AI make ransomware worse?
Yes. AI already writes perfect phishing emails and may soon help break encryption.
Has any country banned ransom payments?
Some U.S. states and companies have policies against it, but no full country ban yet.
What can I do right now to protect myself?
Back up important files offline, keep software updated, and never click unknown links or attachments.
