What is ransomware

One of the most common types of cyberattack is ransomware. Ransomware can lock up your computer’s data and hold it hostage until you pay a ransom to the attacker. These attacks can be devastating if you’re not properly prepared. In this article, we’ll explain everything you need to know about ransomware: what it is, how it works, and what you can do about it. View Deal What is ransomware? Ransomware is a type of malware that reversibly encrypts files on your computer. While many individuals and businesses routinely encrypt their files for security, ransomware is problematic because the attacker—not the owner of the computer—has the decryption key. This means it’s impossible for users to access their files unless the hacker decrypts them. Some ransomware will delete your files after a specific, predetermined amount of time passes, which puts pressure on victims to pay up quickly. In other ransomware attacks, the attacker will also steal copies of your data and threaten to release them if you refuse to pay. This type of ransomware attack can be particularly problematic for large companies and government agencies that store sensitive data. There’s no guarantee that an attacker will decrypt your files even if you pay. However, in most cases, cybercriminals will do what they promise. In an illicit twist on traditional business practices, it’s in the attacker’s interest to develop a reputation for following through on their guarantees. Otherwise, there would be little incentive ...

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. The costs can range from a few hundred dollars to thousands, payable to cybercriminals in Bitcoin. How ransomware works There are a number of vectors ransomware can take to access a computer. One of the most common delivery systems is There are several things the malware might do once it’s taken over the victim's computer, but by far the most common action is to encrypt some or all of the user's files. If you want the technical details, the Infosec Institute has In some forms of malware, the attacker might leakware or doxware, in which the attacker threatens to publicize sensitive data on the victim's hard drive unless a ransom is paid. But because finding and extracting such information is a very tricky proposition for attackers, encryption ransomware is by far the most common type. Who is a target for ransomware? There are several different ways attackers On the other hand, some organizations are tempting targets because they seem more likely to pay a ransom quickly. For instance, government agencies or medical facilities often need immediate access to their files. Law firms and other organizations with sensitive data may be willing to pay to keep news of a compromise quiet — and these organizations may be uniquely se...

A ransomware attack is defined as a form of malware attack in which an attacker seizes the user’s data, folders, or entire device until a ‘ransom’ fee is paid. This article aims to give a comprehensive understanding of what a ransomware attack is, its types, encryption techniques, and best practices to prevent and protect from a ransomware attack. Table of Contents • • • • What Is a Ransomware Attack? A ransomware attack is a form of . Ransomware attack exploits the open security vulnerabilities by infecting a PC or a network with a phishing attack, or malicious websites. A ransomware attack compromises a user’s computer by either locking the user out of the system or encrypting the files on the computer and then demanding a payment (usually in Bitcoin) to restore the system or files. This form of attack takes advantage of system networks and system users and exploits A ransomware attack can target an individual, an organization, or a network of organizations and business processes. The attacker can spread malware to a network of computers using various distribution techniques, such as attachments or links in phishing emails, by infected websites. This is done using a drive-by download or via infected USB sticks, pop-ups, social media, malvertising , infected programs, a traffic distribution system (TDS), self-propagation, etc. According to the Vectra 2019 Spotlight Report Opens a new window , recent ransomware attacks have targeted cloud, data center, and enterprise infra...

The malware can also be spread through chat messages, removable Universal Serial Bus (USB) drives or browser plugins. Once the malware is in a system, it will begin encrypting the victim's data. It will then add an extension to the files, making them inaccessible. Once this is done, the files cannot be decrypted without a key known only by the attacker. The ransomware will then display a message to the victim, explaining that files are inaccessible and can only be accessed again upon paying a ransom to the attackers -- commonly in the form of bitcoin. Types of ransomware Attackers may use one of several different approaches to extort digital currency from their victims: • Scareware. This malware poses as security software or tech support. Ransomware victims may receive pop-up notifications saying malware has been discovered on their system. Security software that the user does not own would not have access to this information. Not responding to this will not do anything except lead to more pop-ups. • Screen lockers. Also known simply as lockers, these are a type of ransomware designed to completely lock users out of their computers. Upon starting up the computer, a victim may see what looks to be an official government seal, leading the victim into believing they are the subject of an of...
