I see some 404 errors in my search console panel. it's pages like "/m4eu5ebanday.thermosonde" or "/hgcrdie29intt.navidrex". Such pages never existed on website or sitemap.xml. Also I see notice about them "URL might be known from other sources that are currently not reported". Accourding webserver's logs, that it's really was Google bot. Where could Googbot get these links? Is this preparation for a website hack or something like that?
Google started asking for random pages around the time we started honouring every page request and generating content on the fly. By never having a "bad request" or genuine 404 we looked like spammers. Most of us caught on quickly but I still see sites doing this. So, these requests might be from bad inbound links or they might be checks that you're throwing genuine 404s. Check your CMS that these requests generate the right header codes.
Thanks. I see it third time on my GSC for different websites. All of these websites nor do not generate content on the fly not having such inbound links. My CMS generate 404 error for this request so I guess everything is OK.
It's possible that these URLs were created with bad intentions or due to a server configuration error. It's important to look into this further and make sure you have strong security measures in place to avoid any potential security breaches. Keeping an eye on your website's logs and search console regularly can help you identify and fix any strange activity.
