Ransomware is a type of malicious software that takes full access to your computer and demands a ransom from you. It basically enters your computer and locks your file system or data. You have to pay a huge amount of money to restore it. Now it can happen to any computer at any time.

How it works:

  • Through phishing emails or files
It basically sends a link or file through a phishing email which, once downloaded, takes over your device.
  • Data encryption
Ransomware encrypts important data on the device, causing the user to lose access to it.

  • Demanding ransom
They ask users to pay a certain amount of ransom, which is paid through cryptocurrency (e.g. Bitcoin), to return their data.

There are usually some specific signs to recognize a ransomware attack. These are:
  •  File encryption or locking
Your computer files may suddenly change to an unknown format or extension.
A password or key may be asked when opening the file.
  • Note on the desktop or in a folder (Ransom Note)
After a ransomware attack, a text file, HTML page, or pop-up message will appear on your desktop or in a file.
It will state that your files have been locked and that money (Bitcoin or other cryptocurrency) is being demanded to restore the files.
  •  Computer slowness
Ransomware starts many processes after entering the system, which can slow down the computer.
  •  Antivirus ineffective
Your antivirus or security software may be turned off.
Some security settings in the system may be changed.
  •  Redirection in the Internet browser
The browser may suddenly be redirected to an unknown website.
  •  Ransomware dialog or pop-up window
A special pop-up or lock-like message appears on the screen.


Types of ransomware


There are different types of ransomware, such as:

  • Crypto Ransomware
It encrypts data, thereby blocking user access.
  • Locker Ransomware
It locks the entire system, making it impossible to use the device.
  • Double Extortion Ransomware
In addition to encrypting data, it also threatens to steal it and leak it on the internet.
  • Server Ransomware
It attacks the servers of companies or organizations, thus disabling their entire network.


Ways to prevent ransomware

  • Use anti-malware software
Protect your device by using strong anti-malware software.

  • Warning
Avoid downloading suspicious emails, links or files.
  • System updates
Keep your software and operating system updated to close security vulnerabilities.

  • Suspicious emails
