There are three ways to unzip files on Mac: you can double-click on the zipped file, right-click and click open with Archive Utility or use third-party software. Spammers also use ZIP files as phishing bait, where they camouflage themselves as a bank, business partner, friend, or employer, and instruct the recipient to take specific action. As much as a Mac has a built-in defense mechanism, attackers use ZIP archives to surpass the defense, infect the computer and collect information about the system. The ability to conceal content is what makes ZIP files a hacker's best friend. But they can potentially be - when cybercriminals use them to infiltrate Mac systems. Unless a Mac user uses third-party software, they cannot tell what's inside the zipped folder without opening the file. Usually, ZIP files don't display their content. Unfortunately, cybercriminals also use ZIP files to advance their course. These two features make the ZIP file format one of the most common ways people share files and collections of files online. ZIP file bundles multiple files into a single container file and also compresses them.
