Introducing my latest Burp extension - “Passive Search”. Passive Search searches for a list of terms in HTTP responses and creates an issue if it finds one.
I got the idea of after maintaining a list of things that I was checking for in responses and using either the search in HTTP History on an item by item basis or using the global Search. It was a completely manual process.
Today I started a new project that I’ve been thinking about for awhile. It’s located at – https://appsec.fyi. It is a growing collection of interesting links that I’ve found regarding varying application security topics. The basic site is up and the plumbing is there. Just need to add more content. Check it out!
Python List Comprehensions is a pretty interesting feature that I haven’t seen in other languages (at least that I’ve played with). The basic idea is that they create lists from other iterables. They consists of brackets containing the expression which is executed against each item in the iterable object. One or more conditionals dictate if the item is added to the new list.
The basic format is –
list = [expression for_loop_one_or_more conditions]
Excited to see AuthHeader Updater on a list of awesome burp extensions!
Excited to release Auth Header Updater today – a Burp extension to update Authorization headers during a scan and also guest post about it on ihackthings.online.
Read more about it at ihackthings.online or chs.us.
Source code and plugin available on GitHub. ~
I’ve updated jekyll-clicky to version 0.1.3. This fixes an issue where some posts weren’t getting the javascript code and changed it to be asynchronous..
Check it out at RubyGems and find the source at Github.
Just whipped together a new Burp extension called perfmon (not to be confused with the Windows tool of the same name). I was really interested in the the resource usage of Burp while doing certain activities.
It adds a new tab to Burp and samples every 5 seconds-
Current and max number of threads in use
Current and max memory used
Current and max memory allocated
Ticker to set how often the stats update.
This is the first part in a series that I plan to write on how to create Burp extensions. I became interested in writing Burp extensions at a previous company where we were fortunate enough to be given time to do research presentations and then present them to our peers. My first presentation topic was to write an Active Scanning extension in Burp that would look for XXE (XML External Entity Injection).
BinPeek is an application that checks to see if a Windows application is managed(.NET) or unmanaged(native). It handles x86 and x84 executables. If doing it manually, you must check several values in the PE (Portable Executable) file header that differ slightly based on whether the executable is 32-bit or 64-bit. BinPeek does that work for you.

Install
Build with Visual Studio or just use the release version in the repo.
Sitting here on a cold, snowy day thinking about secure design principles. These are key to think about during the design phase of a feature/project?
Total Mediation – every access to every resource must be validated every time
Economy of Mechanism – keep it as simple as possible
Fail-Safe – in case of failure, default to a secure state
Defense in Depth – layer security
Open Design – the security of a system should not be dependent on secrecy of its design or implementation
