We have always been told not to connect to wifi networks we don’t know and not to share personal information when connected to public networks. However, it now appears that all networks could be vulnerable to hacking. WPA2 protocol, which is used by most connections, has now been proven to be breakable by researchers from Belgium.
This has enormous ramifications for everyday users, as the information we enter is supposed to be encrypted and unreadable. A hack would allow the attacker to steal all kinds of details, like bank information, credit card numbers, address details and passwords. It would also be possible to inject malware into a website.
Any website that does not use HTTPS needs to be considered public and you should use them with caution. You can tell if a website is encrypted by looking for the padlock symbol that appears in the address bar when entering the URL.
