Ransomware is a type of malicious software that encrypts a victim's files and demands payment in exchange for the decryption key. It can infect a computer in several ways, including through email attachments, malicious websites, and software vulnerabilities.
One common method of ransomware infection is through phishing emails. These emails often appear to be from a legitimate source, such as a bank or a trusted company, and contain a link or attachment that, when clicked, downloads the ransomware onto the victim's computer.
Another way ransomware can infect a computer is through malicious websites. These websites may contain pop-ups or ads that, when clicked, download the ransomware onto the victim's computer. In some cases, the ransomware may be disguised as a legitimate software update or download.
Ransomware can also exploit vulnerabilities in software to infect a computer. This is why it is important to keep software up to date with the latest security patches and updates.
Once ransomware infects a computer, it begins encrypting files and displaying a message demanding payment in exchange for the decryption key. Victims are often given a deadline to pay, and if they do not comply, the ransom amount may increase or the files may be permanently deleted.
To protect against ransomware, it is important to regularly back up important files and keep software up to date. It is also important to be cautious when opening emails or clicking on links, and to use antivirus software to detect and remove any potential threats.
