I recently came across some log messages that indicated that someone was trying to compromise a website I manage.

They tried several times to access various url paths that end in `/Telerik.Web.UI.DialogHandler.aspx`

[This page](https://captmeelo.com/pentest/2018/08/03/pwning-with-telerik.html) suggests that accessing that page may be used to compromise a site. 

I don't use any telerik services in my site, but I'm still concerned that someone is trying to get access.

The client IP was 23.101.181.45, which I found to be a [Microsoft server](https://db-ip.com/23.101.181.45)

My web app is hosted in the azure cloud, but I don't believe that this IP has anything to do with my service. My best guess is that this came from an unrelated Azure-hosted virtual machine. 

My question is does this analysis seem valid, and should I do anything about this? I'm afraid of ignoring it.
