WhatsApp, with over 2 billion active users, is a prime target for spyware, despite its end-to-end encryption. If you suspect your account is being monitored, you can take steps to protect your privacy. Check for unusual activity in your linked devices, as spyware can access your conversations through this feature. Enable two-factor authentication for an extra layer of security. Be wary of excessive phone heat, which could indicate spyware running in the background. Lastly, monitor your battery usage, as spyware can drain battery life.
