Vanhoef’s previous research outlined a Wi-Fi attack of Vanhoef, known as Krack. Krack differs from a FragAttack because it does allow the hacker access to sensitive and hidden info. But FragAttack hackers can inflict a lot of damage, especially when combined with other types of hacking.
The vulnerabilities Vanhoef outlines now have been around since 1997 when Wi-Fi first started to be used. can be exploited to inflict other kinds of damage, particularly if paired with other types of hacks.
“It’s never good to have someone able to drop packets into your network or target your devices on the network,” Mike Kershaw, a Wi-Fi security expert, and developer of the open-source Kismet wireless sniffer and IDS, reports.
“In some regards, these are no worse than using an unencrypted access point at a coffee shop—someone can do the same to you there, trivially—but because they can happen on networks you’d otherwise think are secure and might have configured as a trusted network, it’s certainly bad news.”
