How does ransomware work?
Ransomware is a type of malicious software that threatens to publish the victim’s data or perpetually block access to it unless a ransom is paid. While some forms of ransomware specifically target an individual user and their device, other forms of ransomware target entire networks of computers and systems. Regardless of the type of ransomware, the goal is always to extort money from the victim.
Ransomware attacks usually start with a phishing email. The email will contain either an attachment or a link that, when clicked, will download and install the ransomware onto the victim’s device. Once the ransomware is installed, it will scan the device for any files that it can encrypt. Once it has encrypted the files, it will display a ransom note on the victim’s screen with instructions on how to pay the ransom. The ransom will typically be demanded in Bitcoin or another cryptocurrency.
Depending on the type of ransomware, the victim’s data may or may not be accessible after the ransom is paid. In some instances, the victim may be able to use a decryption key to decrypt the files. However, in other instances, even if the ransom is paid, the victim’s data may not be accessible.
Ransomware is a serious threat to both individuals and businesses. It is important to be aware of the dangers of clicking on attachments or links in emails, as this is often how ransomware attacks begin. To protect against ransomware, it is recommended to keep regular backups of all data and to use a reputable antivirus program.
