Interesting find today...

I was perusing the event log on our web server today for any unexpected ASP.NET exceptions/errors. Found the following:

Exception information:

Exception type: HttpException

Exception message: Path '/builder/builder.sitemap' is forbidden.

Request information:

Request URL: https://www.bondwave.com:443/builder/builder.sitemap

Request path: /builder/builder.sitemap

User host address: 66.249.71.247

User:

Is authenticated: False

Authentication Type:

Thread account name: NT AUTHORITY\NETWORK SERVICE

At first I thought this was maybe an attempt by a hacker to mess with the sitemap. Using a handy web site (www.network-tools.com) I did a lookup on the IP address and found it was a Google bot trying to crawl the application. In this case, I would expect an exception or 403 since the site requires authentication anyway.
