Edzel Ares Sy, Sorry for late reply.
If your domain have multisite wordpress installation you need to be careful.
If you have installed wordpress separately in subdomains or subdirectories, Like you install wordpress at Root domain dir eg. example.com and other wordpress installation in 2–3 subdomains like sub1.example.com , sub2.example.com etc., Your all subdomains can be affected by this attack.
Make sure this things. Use beyond comparator and compare your current directory structure on weekly or monthly basis.
