En chiffres
Compromising WhatsApp accounts has become a common digital security threat today. Cybercriminals can impersonate users by accessing their personal information through phishing methods, SIM swapping, and unsecured public Wi-Fi networks.
Although the app does not send automatic notifications for unauthorized logins, it provides various tools to detect suspicious activities. Checking linked devices, paying attention to unsolicited verification codes, and monitoring sudden changes in profile information provide important clues that the account has been stolen.
The most effective way to keep your account secure is to immediately log out of unknown devices' sessions and enable two-step verification. Additionally, keeping the app up to date and always logging out after using it on someone else's device are of critical importance for your security.
