Welcome!
On my site, I've published a couple of spelunking tools that I've written over the years.
ieHTTPHeaders
ieHTTPHeaders is an HTTP sniffer for Microsoft Internet Explorer. It will show you the HTTP traffic between your browser and the Web server. Get it here...
httpeyes
Like ieHTTPHeaders, this is an HTTP sniffer, but this one works with any application and not just with Microsoft Internet Explorer. Get it here...
comTrace
comTrace is a COM sniffer that will infiltrate selected processes and trace the calls made on your COM-objects. Can be handy for spelunking and/or debugging. Get it here...
Developer Playground
Another spelunking utility. This one I wrote together with Kim Gräsman. It will infiltrate selected processes with the possibility to trace calls made to imported modules. Get it here...
runAsLimitedUser
A simple Windows shell add-in that simplifies the usage of RunAs, using an account that has a very limited set of priviledges. Get it here...
chainHook library
ChainHook is my own homebrewed API interception implementation. Used in above mentioned tools. Get it here...
ccm
ccm is a tool that analyzes c, c++ and c# code and reports back on its cyclomatic complexity. Get it here...
