I was unaware. Thank you.
Yeah, thats very weird. I dunno if that is some new quirk, but it definitely sounds wrong. You can also cat /etc/groups to see what groups a user has been added to, maybe something was preventing that file being updated?
Where was the FTC action when it was revealed that period apps were selling user data? Does the FTC not care about 2nd class citizens? (Sarcasm and rhetorical if it wasn't clear)
Edit: Turns out they did, good.
The second option to market place was gumtree no? So you're actually the third...
Normally groups update at login, so logging in and out should have done it. When your logged in, groups should give you your active groups.
No hate, just a joke.
I'm a little shocked that he can read. Maybe they just bolded all the times he gets to say "family".
That one is mostly language agnostic.
The setup they have requires a pair of huge antennas, so pulling that off surreptitiously feels unlikely. They also had a controlled lab environment, so who knows how it would work in a less controlled RF space.
Definitely cool research, but this isnt a viable attack vector IMO.
The N in NFC is Near. For someone to exploit it they need to be within centimeters of your device. Even if you can do it at 1m, thats close enough that it can just be stolen from you.
Also, your link to rfidgate appears broken.
At most, i would expect the fan in the airfryer to spin faster, but i don't believe there is a relationship between frequency and power.
Resistive heating elements in airfryers should also be unaffected by frequency.
My guess is that heating element is tuned for 220v, but at 230v it goes to a much higher temperature? Or they suck at cooking :)
Edit: thinking more, a 20% faster fan could definitely be the issue.
