Remember the KRACK attack?
It was bug-of-the-week about a month ago.
KRACK documented a way that you could, in theory, snoop on wireless data – albeit typically only tiny amounts, and with quite a lot of difficulty – even on encrypted wireless connections.

So, we asked Sophos security expert Luke Groves to talk us through the question, “Is Wi-Fi still safe to use?”
