It can also spread through malicious email attachments, infected websites, or file-sharing networks. Once a computer is infected with TAMECAT, it can steal sensitive information, delete files, disrupt system operations, and serve as a backdoor for other malware to enter the system. Users should be cautious when downloading files or clicking on links from unknown sources to prevent TAMECAT infections.
