As WhatsApp account hijacking incidents rise, protecting your account becomes paramount. Beyond staying vigilant against scams, follow these essential practices to safeguard your account: 

1. Avoid Suspicious Links and Files: Never click on links or open files from untrusted sources or text messages. Visit websites via official URLs. 
   
   
2. QR Code Caution: Be wary of Quick Response (QR) codes with unknown URLs, especially if they come from untrusted sources. Malicious websites may be linked through such codes. 
   
   
3. Regularly Review Linked Devices: Check your linked devices in WhatsApp settings to ensure no unknown device accesses your account. Remove any suspicious devices promptly. 
   
   
4. iPhone users: Go to Settings > Linked Devices.  
   
   
5. Android users: Tap on the three dots in the top right corner > Linked Devices  
   
   
6. Enable Multi-Factor Authentication (MFA): If available, activate MFA for an extra layer of security. 
   
   
7. Protect Registration Codes and Passwords: Never share your 6-digit registration code received via SMS or your account password with others. 
   
   
8. Guard Personal Information: Avoid sharing personal details via WhatsApp or other social media tools. 
   
   
9. Public Wi-Fi and Computers: Refrain from logging into your personal account while using public Wi-Fi networks or public computers. 

If you suspect your WhatsApp account is compromised, take immediate action: 

1. Check Linked Devices: Verify if any unauthorized devices are linked to your account. If found, log out all devices simultaneously. 
   
   
2. Reset Password and Enable MFA: Change your WhatsApp account password using a clean device and enable MFA. 
   
   
3. Review Messages and Files: Examine sent or deleted messages, voice recordings, and files in your chats. Notify contacts about unusual or suspicious messages, especially those requesting urgent funds. 
   
   
4. Verify Contact Person: If someone is requesting money transfer, verify with the person via a trust channel. 
   
   
5. Report Incident: If there is any financial loss, report to the Police immediately.
