Well, probably infection, I wanted to say. So you need to find the malicious code, look at the rights to the files, update joomla, maybe they installed some kind of "left" module / plugin, and then change the passwords. If possible, roll back to a late backup, where everything was fine and check all of the above.
Check the server settings at the same time, if it is yours. Well, read the articles on the subject of site security on joomla. The first thing that googled, for example, is joomfans.com/blogs/bezopasnost-sajta-na-cms-joomla...

Answer 2

check js scripts
