Phone hacking refers to the unauthorized access of a mobile device, often to steal personal information or gain control over the phone. This can involve exploiting software vulnerabilities, using malware, or employing social engineering tactics to trick users into revealing sensitive data. Common targets of phone hacking include private messages, contacts, and financial information. Hackers may use this information for identity theft, fraud, or to spy on individuals. Protecting against phone hacking involves using strong passwords, enabling two-factor authentication, and keeping software updated to close security gaps.
