The National Cybercrime Investigation Agency (NCCIA) has issued an advisory for WhatsApp users, urging immediate action in case of account loss or suspected hacking, advising users to uninstall and reinstall the app, log in with their phone number, and enter the six-digit SMS verification code, which automatically logs the hacker out as WhatsApp can only be used on one device at a time; the agency also reassured users not to panic if a seven-day wait is required due to two-step verification, clarifying that the account remains inaccessible to everyone during this period and user data stays secure.
