One common technique used to distribute malware is via exploit kits, which take advantage of vulnerabilities in software to install malware on the victim's system. Another method is to use botnets, which are networks of infected computers controlled by a remote attacker. These botnets can be used to send out spam emails containing malware attachments or links to infected websites. Additionally, hackers may also use malicious advertisements, known as malvertising, to distribute malware by injecting malicious code into legitimate online advertisements.
