What are the security risks of loT device ?

security risks of IoT (Internet of Things) devices --- ⚠️ Security Risks of IoT Devices The Internet of Things (IoT) has transformed our lives, connecting everything from smart thermostats to wearable health monitors. However, with this convenience comes a significant downside: security risks. Below are some of the most critical concerns: 1. **Weak or Default Passwords** Many IoT devices come with default usernames and passwords (like “admin/admin”), which users often don’t change. Hackers can easily guess these credentials and gain access. 2. **Lack of Regular Updates** IoT manufacturers sometimes neglect to issue regular firmware or security updates. This leaves devices vulnerable to known exploits. 3. **Unencrypted Communication** If a device transmits data without encryption, attackers can intercept sensitive information, such as location, passwords, or personal habits. 4. **Botnet Attacks (e.g., Mirai)** Compromised IoT devices can be t...
