There are some examples Spyware Steal your personal information or Ransomware This locks your system or turns the device into a robot for a distributed denial of service attack.

This has the potential to give them access to sensitive information, such as login credentials, credit card details, or private messages. In some cases, they may even modify data, resulting in fraud or data breaches.

Hackers often take advantage of public Wi-Fi, but some may take a step further and create fake hotspots under their control. To help you avoid these pitfalls, these are some common signs of rogue Wi-Fi networks.

- Exceptional behavior: If you encounter strange popups, ads, frequent Wi-Fi disconnects, or slow speeds, it can damage the network you are connected to. To reduce risk, disconnect and run immediately Malware Scan.
