What are some common techniques used to distribute malware?

### REPLY:
One common technique to distribute malware is through a botnet, which is a network of infected computers controlled by a hacker. The hacker can then use these compromised computers to send out spam emails containing malicious attachments or links. Another method is to exploit vulnerabilities in software or operating systems to gain unauthorized access to a device and install malware without the user's knowledge or consent.
