I think you have missed the point that all current Devuan releases ship more
recent versions of OpenSSH than required by this test (6.7 or earlier):

openssh    | 1:7.9p1-10+deb10u2 | oldoldstable           | source
openssh    | 1:7.9p1-10+deb10u2 | oldoldstable-debug     | source
openssh    | 1:8.4p1-2~bpo10+1  | buster-backports       | source
openssh    | 1:8.4p1-2~bpo10+1  | buster-backports-debug | source
openssh    | 1:8.4p1-5+deb11u3  | oldstable              | source
openssh    | 1:8.4p1-5+deb11u3  | oldstable-debug        | source
openssh    | 1:9.2p1-2+deb12u3  | stable                 | source
openssh    | 1:9.2p1-2+deb12u3  | stable-debug           | source
openssh    | 1:9.8p1-8          | testing                | source
openssh    | 1:9.8p1-8          | unstable               | source
openssh    | 1:9.8p1-8          | unstable-debug         | source

-G is now a legitimate ssh option (see ssh(1)).

We have reviewed the article you provided and can find no evidence of compromise
of Devuan installations. It is also worth noting that all of Devuan's openssh
packages come directly from Debian, so it would likely be Debian that was
compromised.

I will close this report now, but if you feel we have misunderstood you or
missed something, please feel free to reopen.

Best wishes

Mark
