Wifi Attack Vulnerabilities

 Had cause to take a closer look at IOT, and other often Wifi enabled systems.   So their vulnerabilities is of concern.   Good intro piece in Wired:

Decades-Old Flaws Affect Almost Every Wi-Fi Device

The so-called Frag Attack vulnerabilities could let hackers steal data or compromise connected gadgets.

A SET OF vulnerabilities in how Wi-Fi is designed and used in practice expose virtually every Wi-Fi-enabled device to some form of attack. A handful of those flaws have been around since the original Wi-Fi standard debuted in 1997. 

The findings, publicly disclosed this week by New York University Abu Dhabi researcher Mathy Vanhoef, show that an attacker within Wi-Fi range of a target network could potentially exfiltrate data from a victim and compromise their devices. But while the sheer scale and scope of the exposure is staggering, many of the attacks would be difficult to carry out in practice, and not all Wi-Fi devices are affected by all of the flaws.  ...
