Trying to append absolute path error , w00tw00t attack and vibe.d app

Posted Mon, 23 Jun 2014 18:13:31 GMT

I have a test application running on an Amazon EC2 with nginx.

I got this error and the app crashed.

Path 'w00tw00t.at.blackhats.romanian.anti-sec:)' -> '/w00tw00t.at.blackhats.roma
nian.anti-sec:)'
Task terminated with unhandled exception: Trying to append absolute path.

I think this w00tw00t kind of attack contains a GET request without a host.

Additionally how can somebody be notified when an app is crashing on the server? Could it be programmed in the vibe.d app itself or by using another application or script?

Thanks.
