Breaking into and Reverse Engineering iOS Photo Vaults

Every so often we hear stories of people losing their mobile phones, often with sensitive photos on them. Additionally, people may lend their phones to friends only to have those friends start going through their photos. For whatever reason, a lot of people store risqué pictures on their devices. Why they feel the need to do that is left for another discussion. This behavior has fueled a desire to protect photos on mobile devices. One popular option are photo vault applications. These applications claim to protect your photos, videos, etc….

The iOS Get out of Jail Free Card

If you have ever been part of a Red Team engagement, you will be familiar with the “Get out of Jail Free Card”. In a nutshell, it’s a signed document giving you permission to perform the activity you were caught doing. In some instances, it’s the difference between walking away and spending the night in a jail cell. You may be saying, “Ok, but what does a Get out of Jail Free Card have to do with iOS applications?” Well, iOS mobile application assessments usually occur on jailbroken devices, and…

Bad Crypto 101

This post is part of a series about bad cryptography usage . We all rely heavily on cryptographic algorithms for data confidentiality and integrity, and although most commonly used algorithms are secure, they need to be used carefully and correctly. Just as holding a hammer backwards won’t yield the expected result, using cryptography badly won’t yield the expected results either.   To refresh my Android skillset, I decided to take apart a few Android applications that offer to encrypt personal files and protect them from prying eyes. I headed off…

Silly Bugs That Can Compromise Your Social Media Life

A few months ago while I was playing with my smartphone, I decided to intercept traffic to see what it was sending. The first thing that caught my attention was the iOS Instagram app. For some reason, the app sent a request using a Facebook access token through an HTTP plain-text communication. Here is the original request that I intercepted from the Instagram app:   POST /api/v1/fb/find/?include=extra_display_name HTTP/1.1 Host: instagram.com Proxy-Connection: keep-alive Accept: */* Accept-Encoding: gzip, deflate Content-Length: 337 Content-Type: multipart/form-data; boundary=Boundary+0xAbCdEfGbOuNdArY Accept-Language: en;q=1, es-MX;q=0.9, fr;q=0.8, de;q=0.7, zh-Hans;q=0.6,…

Personal banking apps leak info through phone

For several years I have been reading about flaws in home banking apps, but I was skeptical. To be honest, when I started this research I was not expecting to find any significant results. The goal was to perform a black box and static analysis of worldwide mobile home banking apps. The research used iPhone/iPad devices to test a total of 40 home banking apps from the top 60 most influential banks in the world.
