Common Ways Ransomware Infects Systems
Ransomware can infect systems through various methods, including phishing emails and social engineering, malicious websites and downloads, and exploiting vulnerabilities in software and systems.
Phishing emails are one of the most common ways ransomware is delivered to victims. Attackers send emails that appear to be from a legitimate source, such as a trusted company or organization, and trick the recipient into clicking on a malicious link or opening an infected attachment. Once the victim interacts with the email, the ransomware is downloaded onto their system.
Malicious websites and downloads are another common method of ransomware infection. Attackers create fake websites or distribute infected files that appear to be legitimate software or documents. When the victim visits the website or downloads the file, the ransomware is installed on their system.
Exploiting vulnerabilities in software and systems is another way ransomware can infect systems. Attackers take advantage of security flaws in software or operating systems to gain access to a victim’s system and install the ransomware. This can happen if the victim has not installed the latest security patches or updates.
