Is a type of malware in which the data on a victims computer is locked and payment is demanded before the data is unlocked?
Ransomware is one of the most damaging types of malware, causing billion-dollar disasters every year. For businesses and individuals alike, a ransomware infection can mean losing irreplaceable files and spending weeks recovering computers. Show
In this article, we’ll explore the definition of ransomware, how it works, and how to get it off of your computer. Ransomware definitionLike adware and spyware, ransomware is a type of malware. Unlike some other kinds of malware, ransomware has a very specific definition: it’s malicious software that encrypts the victim’s files and demands a ransom to decrypt them. Generally, the ransomware author requests their ransom in Bitcoin or another hard-to-trace cryptocurrency. While most types of ransomware only encrypt a user’s files, others threaten to publish them as well. Because of this, ransomware can be hugely damaging to an organization, both in terms of finances and reputation. How ransomware worksIn a nutshell, ransomware abuses encryption, a technology for scrambling data, to prevent victims from accessing their data unless they pay up. After a victim unwittingly installs it, the ransomware follows a few general steps:
Encryption is the same technology used to make online banking secure. It also secures your web browsing, instant messages, and emails (between major providers). However, hackers can also use encryption to lock their victims out of their own data. How does ransomware spread?There are a few different ways of infecting users with ransomware. Below, I answered some of the most burning questions about the spread of this malicious software:
Unfortunately, ransomware is extremely quick once it gets into your system. It only takes a few seconds to encrypt all your files. That’s why you should focus on avoiding it in the first place. What are the types of ransomware?Ransomware has been one of the most popular and successful malware types these days. With it, cybercriminals can successfully block access to your own data and devices, steal sensitive information, and earn a fortune by forcing you to pay a ransom. That’s why ransomware is constantly evolving and even has 4 different types – locker, crypto, double extortion, and RaaS ransomware. But the two main ones are locker and crypto-ransomware. Locker RansomwareThis type of ransomware completely blocks access to your device. It uses stolen credentials and social engineering techniques to get into the system. After it gets into the system, the cybercriminals demand for you pay the ransom. However, the damage doesn’t resolve as the intruders already have your data. Crypto-ransomwareBy using this type of ransomware, the hacker seeks to decrypt your sensitive information by not compromising your computer’s functionality. Once the hacker is in, you can only see your files but not access them. At this point, you also receive a message informing you about the ransom and the possible loss of files if you don’t pay the required amount of money. As we can already see, ransomware is a quick and easy way to steal files and earn money for the bad guys. And one of the best ways to stay protected is to use the best ransomware protection from our listed software. How to prevent ransomwareMost types of ransomware require some kind of user error to trigger. On occasion, ransomware will use security vulnerabilities in software or remote access protocols to spread. Generally, preventing ransomware attacks is similar to preventing other kinds of attacks. Here are some more specific recommendations:
Other general security measures might keep ransomware at bay, but the user is the most important element of the security system. By being careful and skeptical of websites, emails, and other information on your computer, you can avoid ransomware. How to remove ransomwareSince your files are completely encrypted, it’s impossible to remove ransomware without totally wiping and reinstalling your computer. You won’t be able to get back your files without having a backup from before the ransomware was installed. Here’s how to wipe and restore your computer:
If you don’t have a backup of your files, you might be out of luck. In the final section of this article, we briefly discuss why you shouldn’t pay the ransom. There’s no guarantee that the criminal won’t simply take your money without restoring access to your files. On the other hand, if you’re fine losing your files, just wipe your computer completely and don’t restore any backups. Ransomware examplesIn recent years, ransomware attacks have shown up in the news all the time. From the famous WannaCry attack that hit hundreds of major organizations to the Petya and NotPetya variants, ransomware has been a hot topic for a few years. You can see a summary of the most significant ransomware variants here:
Should I pay if I get hit by ransomware?If at all possible, do not pay the ransom. By paying the ransom, you’re encouraging the ransomware authors to continue attacking other individuals and organizations. However, sometimes you can’t avoid paying the ransom because you don’t have backups and the value of your data exceeds the cost of the ransom. Remember that the ransomware authors have no incentive to actually unlock your files if you pay the ransom. Although most of the time they do unlock victims’ files, there is no guarantee. When a Kansas hospital was hit with a ransomware attack, their data was not returned, even after paying the ransom. Another reason to avoid giving in is the possibility that other malware was installed at the same time. Malware often comes in groups—even if you pay to remove the ransomware, your computer might still be infected with other, more subtle malware. If you prepared well and you have backups, wipe every infected computer and restore from your backups. This way, you’ll still have your data and won’t encourage cybercrime in the future. FAQCan ransomware infect the external hard drive?Yes. Sometimes, ransomware can encrypt even external storage devices. To avoid this, don’t keep your external hard drive permanently connected to your computer. How common are ransomware attacks?Unfortunately, they are pretty common. It is estimated that a few thousand ransomware attacks occur every single day. Should you pay ransomware?If possible, no. Paying the ransom only encourages hackers to infect more devices. Also, there are no guarantees that your data will be decrypted. Can ransomware steal data?Yes. Some types of ransomware can steal all your personal data before encrypting your files. Is a type of malware in which the data on a victim's computer is locked and payment is demanded before the data is unlocked?Ransomware is a type of malware attack in which the attacker locks and encrypts the victim's data, important files and then demands a payment to unlock and decrypt the data.
What type of malware can lock you out of your files?Ransomware / Crypto-Malware
Ransomware is a type of malware designed to lock users out of their system or deny access to data until a ransom is paid.
What is the name of the malware that can lock you out of your computer and prevent access to your data until you pay a fee to the software developer?Ransomware definition
Ransomware is a form of malware that encrypts a victim's files. The attacker then demands a ransom from the victim to restore access to the data upon payment. Users are shown instructions for how to pay a fee to get the decryption key.
What kind of malware is ransomware?Ransomware is a type of malicious software (malware) that threatens to publish or blocks access to data or a computer system, usually by encrypting it, until the victim pays a ransom fee to the attacker. In many cases, the ransom demand comes with a deadline.
