Ransomware has become one of the most dangerous cyber threats in the United States, targeting hospitals, schools, businesses, and even government agencies.
What Is Ransomware?
Ransomware is a form of malicious software that blocks access to systems or encrypts files until a payment is made. Cybercriminals use it to extort money, often demanding cryptocurrency such as Bitcoin. In the United States, ransomware incidents increased by over 70% between 2022 and 2025, impacting sectors like healthcare, finance, and education.
There are 3 key characteristics of ransomware attacks:
- Files or systems become inaccessible
- A ransom demand message appears
- Payment instructions are provided with a deadline
For example, a small business in Texas lost access to 12 years of customer data in 2024 after a ransomware attack locked its servers and demanded $85,000 in Bitcoin.
Is Ransomware a crime?
Yes, ransomware is a crime. Specifically, it falls under the category of cybercrime and is illegal in virtually every jurisdiction worldwide.
Conducting a ransomware attack involves several distinct criminal acts:
- Unauthorized Access: Breaking into a computer system or network (hacking).
- Extortion: Demanding money or assets through coercion or threats.
- Data Interference: Damaging, deleting, or altering data without permission.
- Money Laundering: Processing ransom payments (often in cryptocurrency) to hide their illegal origin.
In many countries, these actions are prosecuted under specific laws, such as the Computer Fraud and Abuse Act (CFAA) in the United States or the Computer Misuse Act in the UK. Law enforcement agencies like the FBI and Interpol actively track and prosecute the individuals and organized groups behind these attacks.
How Ransomware Works (Step-by-Step Process)?
Ransomware attacks follow a structured process. Understanding these steps helps in prevention and response.
1. Initial Access
Attackers gain entry through:
- Phishing emails (90% of attacks begin this way)
- Malicious attachments like PDFs or Word files
- Compromised websites or fake downloads
- Weak passwords or Remote Desktop Protocol (RDP) breaches
Example: An employee clicks a fake invoice email, downloading malware.
2. Execution and Installation
The malware installs silently in the system. It may:
- Disable antivirus software
- Create backdoors for attackers
- Spread across the network
3. Lateral Movement
Attackers move through the network to access critical systems such as:
- Databases
- Backup servers
- Cloud storage
Large enterprises in the U.S. report attackers staying hidden for 7 to 21 days before launching the attack.
4. Data Encryption or Theft
Files are encrypted using strong algorithms like AES-256. Some attackers steal sensitive data before encryption.
5. Ransom Demand
A message appears, such as:
“Your files are encrypted. Pay 3 Bitcoin within 72 hours or lose your data permanently.”
Types of Ransomware
1. Crypto Ransomware
Encrypts files and demands payment.
- Example: WannaCry (affected 200,000 computers globally)
2. Locker Ransomware
Locks users out of their devices completely.
- Example: Police-themed ransomware scams
3. Double Extortion Ransomware
Steals data and threatens to publish it.
- Example: Maze ransomware
4. Triple Extortion Ransomware
Targets victims, customers, and partners simultaneously.
5. Ransomware-as-a-Service (RaaS)
Cybercriminals sell ransomware kits.
- Example: LockBit and REvil
6. Mobile Ransomware
Targets smartphones and tablets.
7. Doxware (Leakware)
Threatens to leak sensitive data instead of encrypting it.
Ransomware Examples in the U.S.
Colonial Pipeline Attack (2021)
- Impact: Fuel supply disruption across 17 states
- Ransom Paid: $4.4 million
Change Healthcare Attack (2024)
- Impact: Nationwide healthcare billing disruption
- Millions of patient records affected
MGM Resorts Attack (2023)
- Impact: Casino systems shut down for days
- Estimated loss: $100 million
U.S. Laws and Regulations on Ransomware
Ransomware falls under several U.S. legal frameworks:
1. FBI and CISA Guidelines
- Strongly discourage paying ransom
- Encourage reporting incidents immediately
2. OFAC (Office of Foreign Assets Control)
Paying ransom to sanctioned entities may violate federal law.
- Civil penalties can reach $307,922 per violation (2025 update)
3. State Data Breach Laws
All 50 states require notification if personal data is compromised.
4. HIPAA (Healthcare Sector)
Healthcare providers must report ransomware attacks involving patient data.
Why Paying Ransom Is Discouraged?
There are 5 major reasons U.S. authorities advise against paying:
- No guarantee of data recovery
- Encourages more attacks
- Funds criminal organizations
- Possible legal violations (OFAC sanctions)
- Repeat targeting of victims who pay
The FBI reports that only 65% of organizations regain full data after payment.
What To Do If Attacked by Ransomware?
Take these steps immediately:
Step 1: Disconnect Systems
Disconnect infected devices from the network to stop spread.
Step 2: Do Not Pay Immediately
Evaluate options before making decisions.
Step 3: Report the Incident
Contact:
- FBI Internet Crime Complaint Center (IC3)
- CISA
Step 4: Identify the Ransomware
Use tools like:
Step 5: Restore From Backup
Restore clean data, if backups are available.
Ransomware Removal Tactics
There are 4 proven removal approaches:
1. Use Antivirus and Anti-Malware Tools
Tools such as Malwarebytes, Bitdefender, and Microsoft Defender can remove infections.
2. System Restore
Restore system to a previous clean state.
3. Decryption Tools
Some ransomware variants have free decryptors available.
4. Professional Incident Response
Hire cybersecurity experts for enterprise-level attacks.

How Organizations Can Prevent Ransomware?
1. Implement Multi-Factor Authentication (MFA)
Adds an extra layer of security.
2. Regular Software Updates
Patch vulnerabilities quickly.
3. Employee Training
Train staff to identify phishing emails.
4. Secure Backups
Maintain 3 copies of data, store 1 offline.
5. Network Segmentation
Limit spread across systems.
6. Endpoint Protection
Use advanced threat detection tools.
7. Email Filtering
Block malicious attachments and links.
8. Access Control
Limit user permissions.
9. Zero Trust Security Model
Verify every access request.
10. Incident Response Plan
Prepare a documented response strategy.
How to Detect Ransomware Early?
Early detection reduces damage.
Look for 5 warning signs:
- Sudden file encryption
- Unusual network activity
- Disabled security tools
- Unauthorized login attempts
- Strange file extensions
Response Strategy (NIST Framework – USA Standard)
The National Institute of Standards and Technology (NIST) recommends:
1. Identify
Understand systems and risks.
2. Protect
Implement safeguards.
3. Detect
Monitor threats.
4. Respond
Contain and mitigate.
5. Recover
Recovery After a Ransomware Attack
Recovery involves 3 phases:
1. Data Restoration
Restore backups and verify integrity.
2. System Rebuilding
Reinstall operating systems and applications.
3. Security Improvements
Fix vulnerabilities to prevent future attacks.
Final Thoughts
Ransomware has evolved into a multi-billion-dollar cybercrime industry affecting individuals, small businesses, and Fortune 500 companies across the United States. Attackers use advanced tactics such as double extortion and Ransomware-as-a-Service to maximize profits.
Strong cybersecurity practices, employee awareness, and a clear incident response plan reduce the risk significantly. Fast action during an attack minimizes damage and speeds up recovery.
Organizations that invest in prevention, detection, and response systems reduce ransomware impact by over 80%, according to industry reports.

Who should I contact after an attack?
Contact FBI IC3 and CISA immediately.
What is ransomware attacks?
Ransomware is a type of malware designed to deny a user or organization access to files on their computer by encrypting them.
The attackers then demand a ransom payment—typically in cryptocurrency—in exchange for the decryption key, often threatening to permanently delete the data or leak sensitive information if the payment is not made within a specific timeframe.
Is ransomware a type of malware?
Yes, ransomware is a specific category of malware (malicious software).
While “malware” is a broad umbrella term that includes anything designed to damage, exploit, or gain unauthorized access to a computer system—such as viruses, worms, and spyware—ransomware is distinguished by its unique method of extortion.
Instead of simply stealing data or damaging the OS, ransomware takes the system or its data “hostage” through encryption, making it a highly specialized and financially motivated type of malware.
Is ransomware a crime?
Yes, ransomware is a crime. Specifically, it falls under the category of cybercrime and is illegal in virtually every jurisdiction worldwide.
