Trickuri

Manual tests for URL Spoofing scenarios

This tool is designed to allow testing of applications' display of URLs.

Background

URLs are often the only source of identity information available when making security decisions in a web browser or other context, but URL syntax is complicated and subject to a wide variety of spoofing attacks. Trickuri allows easy exercise of common sources of spoofing vulnerabilities to ensure applications are robust in their display of URLs.

Implementation

Trickuri is configured as a proxy server for the client application under test. All of the client's HTTP requests are sent to the proxy. The proxy returns HTML content such that the behavior of the client application can be tested. For instance, for Chrome itself, the tester can examine the content of the omnibox to verify that the origin is visible and unambiguously identified to the user.

Testcases

Files in the testcases folder will be served as if they were served from any URL, i.e. with the proxy running, visiting example.com/samplepathtest will serve testcases/samplepathtest. Additional test cases can be added to the testcases folder.

Running

To run Trickuri, run go run trickuri.go in the source directory.

Proxy configuration

The proxy may be configured in one of two ways:

  1. As a "static proxy", running on port 1270 (by default) of the machine running the proxy.
  2. As an "autoconfigured proxy" where the client pulls http://<IP/hostname of computer running Trickuri>:1270/proxy.pac as the proxy determination script.

The advantage of the latter configuration is that it allows the proxy to specify that it should be bypassed for certain URLs, e.g. those used by SafeBrowsing, component updates, etc. Such bypasses help limit the impact of the proxy on the system under test.

See https://www.chromium.org/developers/design-documents/network-settings for instructions on configuring proxy settings if you are testing Chrome with Trickuri.

Certificate configuration

In order for the tool to be able to intercept HTTPS requests, its root certificate needs to be trusted by the application being tested. If you are testing Chrome, this means that you should import the Trickuri root certificate into your OS trust store. The root certificate can be downloaded from http://localhost:1270/root.cer once Trickuri is running.

Flags

-p Sets the port in which the tool will listen, defaults to 1270.

-h Sets the port for the https server, defaults to 8443.

-d Sets the directory for certificate storage, defaults to ~/.config/trickuri
