What is Ransomware? – Definition, Types and More

Ransomware Definition

The term ransomware derives from the English word “ransom.” It means ransom. Ransomware is a severe malware that attempts to block the use of systems or data.

Ransomware is malicious software that blocks the use of computers or data and demands a ransom for release.

There are methods such as the encryption of files used. Well-known examples of this type of malware include CryptoLocker, WannaCry, or Locky.

However, the malware can affect a wide variety of operating systems such as Windows, Linux, macOS, or Android and hardware platforms such as servers, PCs, tablets, or smartphones.

What is the Infection with ransomware?

The Common ways of infection are via e-mail attachment, via infected websites, by downloading infected software or via prepared data carriers such as USB sticks and memory cards.

Many current virus scanners detect numerous variants of the encryption Trojans and prevent infection. Once the malicious software has settled on a computer.

Some of the malicious programs can spread in the networks as computer worms over incomplete security vulnerabilities.

That’s what ransomware does: lock system

Ransomware locks your computer with a so-called lock screen. It will tell you that an alleged authority is displaying a message. Your system is locked.

  1. If your computer gets with ransomware, a message appears at system startup purporting to be from the police or similar authority.
  2. It states that you as the user, have committed an illegal act. To settle the penalty, you should pay a sum of money.
  3. It is promised to suspend the suspension after payment of the penalty.
  4. And also, it Comes above messages, and you can assume that your PC infects with ransomware. Do not pay any amounts, and the blocking will remain.

What are the different ways of working ransomware?

  • Simple blocking methods are fading of windows, which can no longer close by inexperienced users and make it difficult to use the computer.
  • The software displays hints on how to remove the blockade by paying a ransom. Often this kind of barrier can be canceled with little effort. Data will not be affected in this case.
  • The programs begin without the user being able to encrypt files on the hard disk and connected storage such as cloud storage or server drives.
  • If the files encrypted, then the user no longer has access.
  • And also, The crypto-trojan urges the user to pay a ransom to gain possession of the key. Only with this key, the decryption of the files is possible.

The malware can use different ways of working. As a rule, these two variants are:

  1. Blockade of the system
  2. Encryption of files

Protective measures against ransomware

  • The same protective measures have to take against viruses and Trojans. It has to be aware of current virus software, closes security gaps and responsible use of e-mails or external data.
  • Regular backups allow you to recover the data without paying a ransom. It is essential to keep the backup data separate from the system.
  • And also, An active-backup hard disk connects to the computer also affects by the encryption of the crypto trojan, and the backed-up information is unusable.

Removal of ransomware

  • If ransomware detects on a machine, the system shuts down immediately to stop the encryption of data.
  • Before that, Some anti-malware programs then allow you to remove the ransomware without paying a ransom.
  • Already encrypted files restore using published decryption tools.
