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

      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.

            bruh a unit file can be written to the system or to the user profile

            systemctl --user enable name.service

            And i can most certainly write bash, and do write bash scripts, that write unit files to both user and system profiles.

            Maybe you dont know what your talkign about. just because most install scripts don’t include enabling the unit file for the system, doesn’t mean they can’t.

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

                The fuck are you talking about?

                https://wiki.archlinux.org/title/Systemd/User#Basic_setup

                Basic setup

                All the user units will be placed in ~/.config/systemd/user/. If you want to start units on first login, execute systemctl --user enable unit for any unit you want to be autostarted.

                Comprehension is a problem in this community.

                Apparently so is RTFM and understanding how things actually work.

            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.service

              This 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.

            OK… challenge accepted. Maybe you don’t know about systemd user services.

            Content of mytrojan.sh:

            #!/usr/bin/env bash

echo "Writing the service unit file"

cat > ~/.config/systemd/user/my_test_service.service << EOF
[Unit]
Description=Script Daemon For Test User Services

[Service]
Type=simple
User=
#Group=
ExecStart=/home/user/bin/myscript.sh
Restart=on-failure
StandardOutput=file:%h/log_file

[Install]
WantedBy=default.target
EOF

echo "Reloading systemd for the user"
systemctl --user daemon-reload || exit 1

echo "Enabling and starting the service"
systemctl --user enable --now my_test_service.service

            Content of myscript.sh:

            $ cat ~/bin/myscript.sh
#!/usr/bin/env bash

while true
do
    now=$(date)
    me=$(whoami)
    echo "User $me at $now"
    sleep 10
done

            Now run the script (mytrojan.sh) and check service status after that:

            $ ./mytrojan.sh
Writing the service unit file
Reloading systemd for the user
Enabling and starting the service
$ systemctl --user status my_test_service.service
