A ZIP archive is a file format that compresses one or more files into a single package, reducing storage space and simplifying file transfer. ZIP files are commonly used to bundle documents, images, or software for easier sharing and downloading. While they are a convenient way to organize and transmit data, ZIP archives can also be used to conceal malicious software, as malware can be hidden within compressed files to evade detection by security tools. Opening ZIP files from untrusted sources can pose cybersecurity risks.
