And it's right there in the second line of the article:
> One of the proxy services is a Russian company whose founder’s web hosting business was ground zero for cyberattacks against election systems in Arizona and Illinois in 2016.
Surely a Russian company known for cyberattacks against the US having direct access to the White House network is far more serious than just DDOSing random websites. This is espionage at the highest level. (Again.)
The owner of the proxy is not great, but the fact that its an open door to snoop on everything else on the entire network is the realy fucker there.
