Understanding What Ransomware Is<\/b><\/h2>\n

Ransomware is a type of <\/span>malware<\/b> that encrypts a victim’s files or locks them out of their system, demanding a ransom (usually in cryptocurrency) in exchange for restoring access. It has become one of the most prevalent and financially damaging forms of cyberattacks in recent years.<\/span><\/p>\n

Cybercriminals use various methods to execute ransomware attacks. Understanding the <\/span>types of ransomware<\/b> can help you better prepare.<\/span><\/p>\n

This variant encrypts files on a device or network, making them inaccessible until a ransom is paid.<\/span><\/p>\n

2. Locker Ransomware<\/b><\/h3>\n

Instead of encrypting files, locker ransomware locks users out of their devices, often displaying a full-screen ransom message.<\/span><\/p>\n

3. Scareware<\/b><\/h3>\n

Fake software that claims to find issues on your computer, prompting you to pay to fix non-existent problems.<\/span><\/p>\n
