Hi Yannick,
my own website was hacked today or before and really weird things happened. A Chinese gmail Adress registered my website as an owner in the search console and submitted a txt Sitemap with 1000 Domains.
I have no Idea where this hacker could upload the verification file and the txt file.
In my research now I found some testing?x-wblr-crawler-cdn-bust=17daa457-1e63-4bb1-b3dc-0cc31fa49d96 entries in the 404 records and stuff like forseo/v1/cron/image/2wuzzmxfap7gwf2xxccn58.svg in the 404 records
I also found out that all 404 result in a 301. This seems to be a Joomla bug: https://github.com/joomla/joomla-cms/issues/38785
The problem is, when Google will follow the weird links the guy submitted it will all result in 301 but must be 404 to not cause any harm :-( too bad.
Anyway, the purpose of this ticket is only to let you know of the security incident and maybe something is going on with these testing?x-wblr-crawler-cdn-bust=17daa457-1e63-4bb1-b3dc-0cc31fa49d96 and forseo/v1/cron/image/2wuzzmxfap7gwf2xxccn58.svg entries.
