There are several common techniques used to distribute malware. One method is through malicious email attachments or links, where unsuspecting users are tricked into opening a file or clicking on a link that installs malware on their system. Another technique is through infected software downloads from untrusted sources, where the malware is bundled with legitimate software. Additionally, malvertising is a method where malware is distributed through malicious advertisements on websites, which can infect a user's system when they click on the advertisement.
