Connecting to a free Wi-Fi may compromise your privacy, its not always safe..
A key flaw in the WPA2 WiFi encryption protocol that allows hackers to intercept your credit card numbers, passwords, and sensitive information. The flaw called Key Reinstalled Attack or Krack Attacks is found in the WiFi standard. All the devices using WPA2 encrypted WiFi networks are vulnerable to the attacks. WiFi networks record the MAC address of connected devices, these MAC addresses can easily be carbon copied to impersonate the mobile devices. Any device connected to a router using WIFi can be exploited using the vulnerability found in WPA2 encryption. The report published by the security researcher, Marthy Vahoef, and Frank Piessens talks about these serious vulnerabilities found in WPA2 protocol. Faking the MAC address and forcing it to connect to the fake WiFi network is an easiest to cause 'man in the middle' attacks. If the device tries connecting to the original network, the hacker can even force to bypass it and re-connect it to the rogue one....
