Identity theft occurs when criminals steal personal data such as names, ID numbers, or bank details to commit fraud. Stolen information can be used to open credit accounts, hijack emails, take over insurance policies, or be sold to other fraudsters. Common methods include phishing, social engineering, and unsecured Wi-Fi networks. A scenario illustrates how fraudsters exploit CVs or IDs submitted online to forge fake documents and open illicit accounts. Key prevention tips: verify data requests, limit information shared online, monitor banking activity, secure email, and report suspected fraud immediately to banks and police.
