What Is Ransomware?


Ransomware is a type of malware that blocks access to computer files until a ransom is paid. Files can be encrypted with a key that must be provided by the victim in order to decrypt them. In recent years, ransomware has become increasingly common as cyber criminals take advantage of victims’ fear and ignorance about cyber security. This blog post will explore the basics of ransomware and give an example of how it works. By understanding ransomware, you’ll be better equipped to protect yourself from its effects.

What is ransomware?

Ransomware is a type of malicious software that encrypts files on a victim’s computer, then demands payment from the user in order for the files to be unlocked. Once paid, the ransomware typically removes any encryption it has imposed. In most cases, victims have no way of decrypting the files without first paying the ransom.

How does ransomware works?

Ransomware is a type of malware that encrypts files on a computer, asking the user to pay a ransom in order to restore access to the files. Once encrypted, the files are inaccessible until the ransom is paid. This type of malware has been on the rise in recent years, as criminals have found it to be an effective way to extortionate users.

One of the simplest ways ransomware works is by displaying a message onscreen that warns the user their files have been encrypted and asks for payment in order to unlock them. To make sure people actually pay the ransom, ransomware often includes hidden features that monitor users’ computer activity and alert the attacker if they attempt to restore or copy the file without paying first.

Some common types of ransomware includeLocky and Cerber. Locky was one of the first types of ransomware and features simple graphics that appear when infected files are opened. Cerber is more sophisticated than Locky and can encrypt multiple file types simultaneously. Both Locky and Cerber use AES encryption, which makes it difficult for victims to decrypt their files without help from experts.

What to do if you’re infected with ransomware?

If you find yourself infected with ransomware, the first thing you should do is power down your computer and remove all removable media. Make sure you back up any important files before doing this.

If you can’t access your computer or if it’s already powered down, you’ll need to contact a professional services provider to help restore your data.

How to prevent ransomware infections in the future?

Ransomware is a type of malware that encrypts files on a computer, and then demands a ransom from the user in order to decrypt them. This type of malware is notoriously dangerous because it can encrypt important files, making them inaccessible until the ransom is paid. In addition, ransomware can cause systems to become unstable or even unusable.

To prevent ransomware infections in the future, be sure to keep your software up-to-date and install anti-virus protection on your computer. Additionally, make sure to never pay ransom demands in order to unlock encrypted files. If you do experience a ransomware infection, don’t panic; there are many ways to recover your files without paying the ransom.

What to do if you’re infected with ransomware?

If you’re infected with ransomware, your computer may start to lock up and display a message demanding payment in order to unlock it. The best way to protect yourself is to make sure you have an up-to-date virus protection program installed and regularly updated. If your computer starts locking up, trying to pay the ransom will only make the problem worse. There are a few things you can do if you don’t have access to your computer: -Contact your IT department -Restore from a backup -Enable hidden files and folders If you do have access to your computer, there are several things you can do: -Try deleting the ransomware file or folder -Disable security features that may be preventing you from accessing files -Change your passwords regularly

The history of ransomware

Ransomware is a type of malware that encrypts files on a victim’s computer and demands money from the user in order to release the data. Ransomware has been around for over a decade, but became more prevalent in the late 2000s and early 2010s.

Some of the earliest known examples of ransomware were CryptoLocker, which attacked users in 2013, and Locky, which attacked users in 2014. In both cases, victims were required to pay a ransom in order to regain access to their encrypted files.

Since then, ransomware has evolved into an increasingly popular threat. In 2016, there was a surge in ransomware attacks due to the popularity of WannaCry and NotPetya. WannaCry used EternalBlue exploit software released by the National Security Agency (NSA) earlier that year to infect computers worldwide. NotPetya used a similar exploit to infect computers across Europe before spreading globally.Both outbreaks resulted in widespread disruption and millions of dollars worth of damage.

Nowadays, ransomware is most commonly seen as a form of extortion rather than pure infection vector. Criminals use it as an tool to extort money from victims or hold them hostage until they pay up. They typically target individuals or businesses who are less likely to be able to afford the ransom fee, or who don’t have access to reliable backup systems.

Because ransomware is such a prolific threat, there are many different variants of it out there. Some of the most popular ransomware strains include CryptoLocker, Locky, and Ransomware-as-a-Service (RaaS) malware like Cryptolocker 2 and CryptoWall 3.

 Ransomware works

When a victim’s computer is infected with ransomware, the malware will typically encrypt all of the files on the computer. It will then demand a ransom fee in order to decrypt the files.

Ransomware variants can vary in their methods for collecting ransom payments. Some variants will ask victims to pay using specific payment platforms, while others will simply send a message to victims demanding money.

Once a ransom is paid, the malware will typically release the encrypted files back onto the victim’s computer. However, there is always the chance that the malware could hold onto the files and refuse to release them until a further ransom payment is made.

Ransomware types

Ransomware is a type of malware that infects computers and demands payment from the user in order to release the computer system or data. The most common form of ransomware is encrypts the user’s files with a password, then displays a message asking for a payment in order to unlock the files. In some cases, ransomeware will delete all of the user’s files if they do not pay the ransom.

How to avoid ransomware attacks?

Ransomware is a type of malware that threatens to delete your data or lock your computer unless you pay a ransom. Ransomware can encrypt your files, preventing you from accessing them unless you pay an extortion fee. There is no guarantee that paying the ransom will actually decrypt your files.

Wipe and reformat your hard drive:

If your computer is infected with ransomware, one effective tactic is to wipe the drive and reinstall the operating system. This will erase all of your personal data and restore the computer to its factory condition. Be sure to backup important data before doing this step.

Enable Windows 10 security features:

Windows 10 offers several built-in security features designed to protect you from ransomware attacks. You can protect yourself by turning on at least some of these features: Windows Defender Antivirus, Windows Update for Business, Secure Boot, BitLocker Drive Encryption, and DataProtection API.


Ransomware is a type of malicious software that uses encryption to hold onto a user’s data until the ransom is paid. Ransomware can encrypt files on a computer, demand payment in Bitcoin or another cryptocurrency, or even lock down entire systems until the ransom is paid. Although ransomware has been around for years, recent incidents involving WannaCry and NotPetya have highlighted its growing threat to businesses and individuals. If you’re ever faced with ransomware, there are several steps you can take to try and protect your data and restore access: create backups regularly; install antivirus software; use strong passwords; keep up with updates for your operating system and applications.
