What is a common method for distributing malware over the internet?

Peer-to-peer file sharing is a common method for distributing malware over the internet because it allows users to share files directly with one another without the need for a central server. This decentralized model can make it easier for attackers to distribute malicious content, as users often download files from multiple sources, which may include infected files disguised as legitimate software, music, or video files.

Additionally, peer-to-peer networks often lack sufficient security measures or oversight, making them attractive for the distribution of malware. Users might unknowingly share or download infected files while seeking legitimate content, leading to widespread malware infection across multiple devices and networks. This method exploits the trust among users in the sharing community, as individuals may be less cautious when downloading files from peers they believe to be trustworthy.

In contrast, other options such as secure websites typically have measures in place to protect against such risks, while encrypted messages and social media posts may not inherently focus on file distribution, making them less common for the distribution of malware.
