In case you’re a Windows 7 user looking for an OS replacement when your support ends on January 14, 2020 – Linux is not necessarily the “replacement OS” that you are looking for.
List of tested OSes that are “vulnerable to this attack”:
Ubuntu 19.10 (systemd)
Debian 10.2 (systemd)
Arch 2019.05 (systemd)
Manjaro 18.1.1 (systemd)
Devuan (sysV init)
MX Linux 19 (Mepis+antiX)
Void Linux (runit)
Slackware 14.2 (rc.d)
Apparently other OSes also have problems, e.g. Android and MacOS/iOS have a “slightly different” behavior, but still a vulnerability problem.
I don’t use a Virtual Private Network (VPN), and really know nothing about them beyond it ‘Hiding’ you – though William J. Tolley says that Tor “evidently is not” vulnerable, and I sometimes use that browser. I also use Kodachi that “filters all network traffic through a VPN and the Tor network, obscuring the user’s network location.” Kodachi is the #6 Distro in my Top 10 list. A great portable OS!
I was also waiting for WireGuard – which supposedly gets “released in the next major Linux kernel release, 5.6, in the first or second quarter of 2020.” However, there must be other versions of WireGuard, since they have a ‘Download’ page for it. Well, sorta a ‘download’ for Linux Distros, but since it is still a keyboard based operating system (‘Think’ the modern version of MS-DOS) you’ll need to open a terminal and start typing the ‘Linux sudo command’ stuff. No Linux Distro has the basic “Auto Scroll” mouse function, even after almost 29 years of trying. Don’t be fooled by the radical Linux users’ hype – Linux isn’t the “replacement OS” for Windows 7…it’s OK to piddle with, or as a hobby, but realistically it is nothing more than a ‘Toy OS’ that is fun (sometimes!) to play with. Anyway, my wait to try WireGuard may continue for a while longer, since William J. Tolley also says that it is vulnerable.
IMHO, if you have electricity, you are more vulnerable than you realize. Fact is, if someone wants to ‘spy’ on you there is no VPN that will truly hide you from them. Throw away your phone, have the electric + water + gas + etc shut off to your home, and they’ll send in the camera drones if they want to ‘spy’ on you. Personally, if I was worried about security and ‘Anonymity Online’ I would at least stop using the internet; however, I have found that Windows 10’s Windows Security (which is Free) does as well as Kaspersky (which I used for about 20 years) and/or BitDefender (which I used for about 6 months before moving all computers to WIN10 and/or Linux).
