Last Thursday’s Pizza My Mind was hosted by the digital forensics and software development company Cipher Tech Solutions, Inc. Cipher Tech’s CEO and co-founder Keith Bertolino was the sole speaker for the presentation. The presentation consisted of example scenarios, with most real stories being classified government work, intended to represent how Cipher Tech would conduct its business.
The first story was that of a crime scene. In this scenario the goal was to extract video from a damaged SD card for use in the investigation. Bertolino emphasized how difficult it is to do so, very different than what is shown in tv shows like NCIS. If any data is found it is extracted and standard video software is used to test it. In most cases if the video doesn’t work then it is simply too damaged or jumbled to be of any use. But in some cases the code can be patched in some areas with the help of knowledge of the base working of the media format to recreate the missing sections of code.
The second story was a battlefield. Data from cellphones and apps can be invaluable in a battlefield situation. Recovered phones are connected to communication devices where they can attempt to extract data from various applications such as Facebook. This is also a very difficult process as apps are constantly updating with no clear indication as to what has changed on the non consumer side. APKs can often be downloaded from the internet in the right places and a large amount of testing data make some data discovery possible.
Bertolino ended with a brief discussion about the ease that social media sites can be manipulated and how to discover malware on possibly infected laptops.
