Malicious links can be spread in a large variety of ways. They can be distributed through text messages, email, social media, and any other messaging app that lets you share links, like forums, multiplayer video games, and chat rooms. Infected websites and pop-up ads can be especially riddled with malware.
Not all malicious links come from hackers or scammers — for example, your friend may send you a link to watch a free episode of a new TV show, but the website you’re both watching it on might harbor malware. You should be vigilant about all links, regardless of where they’re from or which app you’re using. Take extra steps to avoid these dangers and use tools to check links before you click.
