It's with a heavy heart that I write this. Long time contributor and friend @Delchi has passed away. RIP
He always answered the phone with "What's the good word?" and had an insatiable hackers curiosity. He pioneered the Hackers with Disabilities to help make #DEFCON more accessible, a selfless soul always on the lookout on how to help.
It will be the first time I have set an account to "In Memoriam" and I am not looking forward to it.

That latest report on mass location surveillance using SS7 makes me want to try a test.
I’ll enable airplane mode and VoLTE, and see how calls and messages perform when only using VPN over WiFi.
If that works reasonably well then the next step is to us a mobile hotspot for the WiFi.
In the end my SS7 location would always show the geolocated IP address of where the VPN terminates.

Several people were arrested during an undercover operation targeting child sex predators in Nevada. One of them is Tom Alexandrovich, who turns out to be the Executive Director of the Israel Cyber Directorate. The child predator was released.
I believe the security community must denounce this person and be banned from the conferences, including BlackHat and DefCon.
@fr0gger since, unfortunately, you are in the picture with this person (LinkedIn account of him was deleted already), and you have a good reputation within our community, would be super cool if you'd take a lead and get in touch with the BlackHat/DefCon organizers.

This research by Marek Tóth presented at #DEFCON is good. The vulnerability he discusses is real.
However, exploiting it requires the attacker to compromise a website and add phantom workflows to it that the victim doesn't notice as suspicious. Not impossible, but also IMO not likely unless you visit shady websites frequently.
Personally, I do not think the likelihood is high enough to disrupt my existing workflows to protect against the attack.
