All Wi-Fi at Risk from Krack Attack

Security researchers have revealed that all Wi-Fi connections are potentially vulnerable to an unprecedented security flaw that allows hackers to snoop on Internet traffic.

The vulnerability, dubbed “Krack” , has been described as a “fundamental flaw” in wireless security techniques by experts. Apple, Android and Windows software are all susceptible to some version of the vulnerability, which is not fixed by changing Wi-Fi passwords.

Dr Gary McGraw, VP of security technology, Synopsys, said: "The KRACK problem is unfortunately a prime example of a design flaw (as opposed to an implementation bug). That’s why KRACK is so pervasive across chips and platforms. Generally speaking, flaws have a much greater impact than bugs and are harder to fix. Building secure software properly addresses both bugs and flaws in equal measure."
