Accepted wisdom is to invoke ssh with an illegal option and check that the expected extra line is there (clean) or missing (infected). chkrootkit uses $(ssh -G) as it's illegal invocation but OpenSSH added the '-G' option to print configuration back in 2014. Long story short - chkrootkit needs to pick a different illegal option. Currently unused options include djruzBHJUZ. Changing the script (2 places) appears to work (I used -H, $(rpm -Vv openssh-clients) to check). ... Searching for Linux/Ebury - Operation Windigo ssh... nothing found ...
