What Is Ransomware and Why Windows Systems Are Targeted

Ransomware is a type of malicious software that locks your files using powerful encryption. Attackers then demand money for a key to unlock them. Windows systems are a common target because they are widely used in homes, offices and organisations. Attackers know there is a higher chance of finding valuable data on Windows devices.

During an attack, the ransomware silently encrypts your files so that you cannot open them. It focuses on documents, images, databases and anything important to your daily life or business. This article will help you understand the steps behind this process and what you can do to protect yourself.

How Ransomware Enters a Windows System

Unsafe paths attackers use

Email attachments

Many attacks begin when you open a harmful attachment that looks genuine.

Fake downloads and unsafe installers

Cracked software, pirated tools or unknown updates often hide malware.

Compromised RDP connections

Weak passwords and open Remote Desktop ports make it easy for attackers to enter.

How attackers gain execution rights

Once inside, they use Windows permissions to run the ransomware quietly in the background.

Initial Execution: What Happens First

• A small dropper file runs automatically.
  
  

• It sets up persistence so it restarts every time Windows boots.
  
  

• Entries are added to startup folders and scheduled tasks.

Did you know?
Most ransomware begins encrypting files within seconds after execution, leaving almost no time to react.

How Ransomware Scans the System for Target Files

Ransomware scans your system and looks for commonly used file formats.

• It avoids system folders because it needs Windows to keep working.
  
  

• It prioritises documents, images, databases and work files.
  
  

• It maps shared folders and network drives to increase damage.

The Encryption Process: How Files Are Locked

File by file locking

The ransomware performs a repeating cycle.

1. Opens your file
   
   

2. Encrypts it
   
   

3. Renames it
   
   

4. Deletes the original version

Strong encryption algorithms

Attackers use AES and RSA based encryption. These are extremely strong and almost impossible to break using normal methods.

Unique encryption keys

• A system key is created for your device.
  
  

• Many types also generate a key for each file.
  
  

• In some cases, they contact a remote command server for additional keys.

Did you know?
Many modern ransomware groups use two layer encryption which makes recovery more challenging.

How Ransomware Spreads Inside Windows Networks

Ransomware spreads quickly inside networks.

• It moves through mapped drives.
  
  

• It abuses SMB sharing.
  
  

• It uses weak passwords to jump between systems.
  
  

• With stolen credentials, it performs lateral movement easily.

Did you know?
Some ransomware strains can infect every device in a network within five minutes.

How Ransom Notes Are Created in Windows

Ransomware usually leaves behind instructions in the form of TXT, HTML or PNG notes.
It may even change your desktop wallpaper to frighten you.
These notes include contact information and payment instructions.

How Windows Security Fails Against Modern Ransomware

Outdated antivirus and missing patches

Attackers exploit zero day vulnerabilities when systems are not updated.

Disabled Defender and firewall rules

Many people turn these off while installing software, allowing malware to enter easily.

Users ignoring early warning signs

You may notice slow performance, renamed files or unknown processes, but many ignore these early clues.

Did you know?
Many attacks succeed simply because users click Allow on security prompts without reading them.

How to Protect Windows Systems from Encryption Attacks

• Keep Windows updated.
  
  

• Use strong passwords and multi factor authentication.
  
  

• Disable unnecessary ports such as RDP.
  
  

• Maintain offline and immutable backups.
  
  

• Use behaviour based security tools instead of only signature based antivirus.
