I have been getting quite a few hits on my webservers for the resource /USH.HTML. I have never hosted this file, and do not know what it is.

Is this a type of robots.txt file or something specific to a certain CMS?


I found out the answer, and it is a similar Japanese website that has a domain very similar to ours, but with a hyphen in the name instead. I guess all the 404s are due to a typo on the referring link.

    A quick Google search didn't turn up anything for me. It might be a file that can be exploited or confirm to a hacker that a specific software package is installed and now that they know it is there they can try to exploit it. Just speculation, though. That's why this is a comment and not an answer.

Is it definitely a bot? Do you have a user-agent? And is there a referer [sic] header for those requests?

A Google search doesn't bring up anything remotely significant so I don't think it's related to robots.txt, nor anything like a bot polling for security flaws.

It is likely to be something simple like a mistyped link to your site - for example you have a page "usb.html" or "rush.html", or perhaps a site with a similar domain name has the page "ush.html".

  • Yahoo, MSN, Baidu and a couple of unknowns from Japan have all tried to access it. The file has never existed and is not similar to any other filename or resource on the site. Sep 23, 2010 at 19:07
  • Then perhaps it's just someone fooling around, OR another site with a similar domain (@DisgruntledGoat) which has the page "ush.html".
