What is Wrong with My website ?Can you Help me [closed]

My Website is working properly but sometimes I saw traffic to post which I haven't created. Here is the "Your New Content " Section in google search Console, How this post Created and Publish I don't Know, but when I Visit these pages. It returns a 404 error enter image description here

Same with google analytics, I'm getting traffic from Unknown Keyword for these Posts as you see in the screenshot enter image description here

But, these Types of Posts are Not in My WordPress Dashboard. I don't know how it created

Can you Please Help me with this?
