Dagah case study – Sasakawa USA institution

Automated mobile device vulnerability assessment, penetration testing, and mobile security awareness training




Sasakawa USA is a non-profit, non-partisan institution devoted to research, analysis, and better understanding of the US-Japan relationship in the areas of security, diplomacy, economics, business, trade, technology, and other matters of common concern.  Given the former role of Adm. Dennis C. Blair, U.S. Navy (Ret.), current Chairman and CEO of Sasakawa Peace Foundation USA as the US Director of National Intelligence and the think tank’s ongoing contact with high-level officials in the US Government, the organization is a target for sophisticated adversaries looking to use it as a stepping stone into government targets.


At Sasakawa USA’s request, Shevirah ran a campaign of social engineering attacks against Sasakawa USA’s employees using the Dagah Mobile Penetration Testing software.  This simulation of real world attacks that Sasakawa USA could face evaluated the mobile hygiene of employees and provided teaching points on how to identify and respond to actual mobile phishing attacks.  The vast majority of cyber attacks begin with phishing.

Shitsco CTF Problem Walkthrough

I started my career doing security research. I guess technically I had a government red team job before that, but to really get where I wanted to go in the industry I did some research, gave some talks, and went from there. But for the past couple of years I’ve mainly been focusing on building my consulting practice, commercializing my mobile security research, and build a product startup. So I haven’t had as much time for research as I would have liked. With the release of our first pro product Dagah I’ve made a resolution to change that. 

I’ve decided to start this blog to post some of my work. My goal is to make everything understandable to someone who has read the exploit development chapters in my book and/or did the exploit development exercises in the OSCP course and exam. I find that even with years of study I sometimes fall into the gaps of assumed knowledge and skipped steps on vulnerability write-ups. What I’ll try and do different here is make everything I post go step by step and include all the background. That might make it really boring to some of […]
