If you have the Brave Browser installed on your Windows devices, then you may also have Brave VPN services installed on the machine. Brave installs these services without user consent on Windows devices.
Brave Firewall + VPN is an extra service that Brave users may subscribe to for a monthly fee. Launched in mid-2022, it is a cooperation between Brave Software, maker of Brave Browser, and Guardian, the company that operates the VPN and the firewall solution. The firewall and VPN solution is available for $9.99 per month.
What’s to stop the installer on Linux from configuring the service such that the service always runs on boot? e.g.
systemctl enable malware.service.Linux doesn’t have “installers” as Linux uses package managers. The only way you can get malware is if you manually add a bad repo.
So it doesn’t really matter in the long run

Are you really serious making this claim? lol.
Yes, prove me wrong. As long as your running a up to date system there shouldn’t be anything that could be easily compromised.
I’ve been using Linux (and UNIX) professionally since the kernel version started with a “1.” I have no need to try to prove anything to you. Linux has installers other than just those invoked by a package manager, and it is laughable that you claim otherwise.
You still need to manually enable the service. The configuration of the service has zero effect on its activation or lifecycle.
Huh? Any script can create a service, enable it and then start it. What would make you think the brave package (or just the application itself) can’t do this?
Not possible to start or enable a created service without user intervention. You don’t know what you are talking about.
Systemd “enabled” services are literal symlinks… whenever a target runs, it tries to start also all the service files on its “wants” directory.
You can literally enable any service for next boot by making a symlink in
/etc/systemd/system/multi-user.target.wants/(or whichever other target you want it to run on) as root (and installation scripts are run as root).ln -s /usr/lib/systemd/system/whatever.service /etc/systemd/system/multi-user.target.wants/whatever.serviceThis is actually very close (just tested and confirmed it). I somehow stand corrected about requiring manual enablement but this is just using the package manager to do the dirty work for you.
However the program itself cannot write into those directories without root permissions. You still have to allow your package manager to do this with root permissions as mentioned.
Installing as user does not require root, to be clear. You can use systemd without root by specifying user.
Installing a package requires root which will automatically give the package manager permission to write anywhere on the system. To create a systemd service in user that will automatically start at boot requires root, someguy here commented with the how.
However you can run any installed binary via Desktop files as a user (no root) on login by writing to
~/.config/autostart.My comment wasn’t about installing the package. You seemed to think that systemd required root, which it does not. Further, you can have systemd user processes start at boot. I do this exact thing with Duplicacy, no root required.
OK… challenge accepted. Maybe you don’t know about systemd user services.

This requires the user to run a script aka manual intervention.
Now imagine that the script is set to run as part of the brave installation - you type “yes” please download brave, brave installs brave and runs this script. Linux isn’t immune to malware as you seem to think.
You would need the power of root to do all these aforementioned things (run a VPN service).
And am not saying that Linux is immune to malware, just that it’s not out of the norm to have package managers install services crucial for operation during installation. Since Windows doesn’t have package managers, I’m gonna replace package managers with packages in this reasoning.
I thought that you only were ignorant, but no, you’re more than that!
Maybe am ignorant but at least I understand the questions before I answer them.

Bruh you just ran the command to enable the ‘written’ service. Comprehension is a problem in this community.
