I mean, you can pentest the President and write about it for Gizmodo because the FBI isn't going to bust you for harmless shenanigans when they have enough problems recruiting security people without antagonizing the community they're trying to recruit from.While we have legal and illegal aspects of culture, China has legal, illegal and quasi-legal.
This is far more your wheelhouse than mine, but is this not a stupendously dumb article? - what did they do besides wardrive Mar-el-lago? - what crime would they be guilty of if they got onto a secure hotel network? Which they didn't? - doesn't an undisclosed cc/ssn leak point more to Verifone than it does whatever user-facing Ruckus/Unifi mesh a hotel has deployed? I mean, I get it. If Trump (or anyone around Trump) puts his phone on a compromised network, there's a very real possibility his/their phone could be compromised. But Gizmodo getting on a boat and going "yeppers, his hotel has Wifi" neither illuminates nor ameliorates this problem. One would assume that any confidential equipment/network/IT present at Mar-el-lago would be substantially more robust than "ATTFreeWifi." I'm hardly a 1337 hax0r but I know how to set up an AES-encrypted private, invisible network on my fuckin' $130 Netgear and I assume the Secret Service/NSA/CIA/DIA/ABC/123 know some tricks I don't?
