title: ASP.NET - Hacking the yellow screen of death
body: <p>In some of my books that I've read, it is stated that it is good to hide yellow screens of death (obviously), but not only for the reason in that it is quite informal to users, but also because hackers can use the information to hack your website.</p>
  
  <p>My question is this.  How can a hacker use this information?  How does a call stack of basic operations of the .NET call stack help hackers?</p>
  
  <p>I attached a yellow screen of death that I encountered on one of the websites that I created a long time ago and it sparked my interest.
  (The error is that it fails when attempting to cast a query string parameter to an int.  Yea, I know its bad code, I wrote it many years ago ;)</p>
