What is a honeypot?

From wikipedia: in computer terminology, a honeypot is a trap set to detect, deflect, or in some manner counteract attempts at unauthorized use of information systems. Generally it consists of a computer, data, or a network site that appears to be part of a network, but is actually isolated and monitored, and which seems to contain information or a resource of value to attackers. Simple Honeypot is a honeypot solution for ASP.NET MVC2+.

Simple honeypot is, simple

Simple honeypot will simply stop bots from submitting spam via public forms on your website. There are some plans to make simple honeypot protect agents more types of spam, so check for new releases.

  • Breaking: Constructor overload for HoneypotAttribute has changed.

What is adds to your solution

  • SimpleHoneypot.dll
  • WebActivator.dll
  • App_Start directory
  • App_Start/SimpleHoneypot.cs

Default configuration of SimpleHoneypot.cs

public static void Start() {

        public static void RegisterHoneypotInputNames(HoneypotInputNameCollection collection) {
            //Honeypot will use 2 words at random to create the input name {0}-{1}

Other configuration options

By Default, Simple Honeypot will render an input with a CSS class name called 'input-imp-long'. You can change this CSS by calling Honeypot.SetCssClassName("newCssName") in the Start function of the SimpleHoneypot.cs class.

The controller

You will need to annotate the Action of your controller with the [Honeypot] Filter Attribute.

[Honeypot, HttpPost]
public ActionResult Comment(BlogComment comment) {
    /* Some Processing */
    return RedirectToAction("Index");

The HoneypotAttribute optionally takes a url to redirect to as a String [Honeypot("/Home/Honeytrap")]

The View

Next, you will need to add a call to the HoneypotInput HtmlHelper in your form.

@using SimpleHoneypot.HtmlHelpers
@model BlogComment

@using(Html.BeginForm("Comment", "Blog")) {
        <input type="submit" value="Comment" />

Adding a class to your style sheet

By default Simple Honeypot will use 'input-imp-long' for the input generated. However, if you used the Honeypot.SetCssClassName("newCssName") you will need to use the custom css name.

.input-imp-long { display: none; }


.newCssName { display: none; }
