 * Every week I’m getting several decades of FILE NOT FOUND errors in my server 
   log. They’re in the form:
    [http://www.blog.com/foo/bar](http://www.blog.com/foo/bar)**/
   test**
 * Somehow, there’s a** /test** appended at the end of URLs, and the referer is 
   empty.
    Is it some sort of malicious attack, trying to exploit some old WP plugin?
   How can I block it, even if it appear to be unharmful? Thanks
 * P.S
    .htaccess and permalinks are OK, and it doesn’t happen when a “normal” user
   visits the blog.

 * Just curious, are all these entries in the logs from the same IP address?

 * That’s a good call, I never tried to check the IPs, I only took a look at the
   error log in Awstats, which doesn’t show IP addresses.
 * Now I checked the access log and… it looks like they’re generated by genuine 
   bingbot IPs:
    207.46.13.102 – – [29/Jan/2015:11:35:37 +0100] “GET /blog/foo/title-
   of-the-post/test HTTP/1.1” 404 11824 “-” “Mozilla/5.0 (compatible; bingbot/2.0;
   +http://www.bing.com/bingbot.htm)”
 * That’s curious.

 * That is strange, and you’re right, that IP is registered to Microsoft.
 * Does your sitemap have /test on the end of the URLs?

 * Negative, I’ve just checked all the URLs (the map is automatically generated 
   by XML Sitemap Generator).

 * It’s Bing crawling through your site. I’m not sure how they work and why it would
   go after a test URL, but I wouldn’t be too worried about it.

 * Yep, at this point I can’t do much.
