Since about 25th January I started to get unusual amount of 404 crawl errors in my GWT all of which point to some strange pages on my site that were never there, I mean there were never there from beginning, which was way back in 2002.
What so strange about it is that GWT will usually point to the page that those broken links had appeared on, but at this point there is nothing to refer to, so I simply cannot see anything. Naturally I went to check my site logs to see if I can find any trace of these links anywhere, but there is nothing there, except from several hundred IP's from china that are trying my site for loopholes in various areas, but either having 404 or 403 responses to there queries. To be on the safer side, I have had to block all of the IP's that I could trace via .htaccess.
I understand that 404 cannot harm the site and SEO in general, which is fine, but is is safe to assume that I should just leave it to Google to decide what to do with all of this errors?
I have checked entire site and DB for possible injections, nothing was found, I also tried fetching site in GWT to see if I can find any trace of clocking or anything else in the source code that should have not been there in the forst place, but found nothing again.
here is few of these URL's
I do not use any unsafe methods in my PHP and all of the queries are checked prior to processing them so that anything that is not in my DB will automatically fire up 404.
I am open for suggestions and your experience on this subject.
