- Unsecured Wi-Fi: If a user’s Wi-Fi connection is not secured, viruses can spread through it.
How Viruses Spread Through Social Engineering
Social engineering is a type of attack that uses psychological manipulation to trick users into opening malicious attachments or clicking on links. Here are some key points to consider:
