What are some common delivery methods used by malware to infect systems?

### REPLY:
One common delivery method used by malware is through phishing emails. These emails are carefully crafted to appear legitimate and often contain malicious attachments or links. When a user clicks on the attachment or link, the malware is downloaded and executed on their system. Additionally, malware can be delivered through watering hole attacks, where attackers compromise trusted websites frequented by the target audience and inject malicious code into those websites.
