In Episode 2 of Data Discourse, Pete Mansmann and Jeff Stiegler break down changes, challenges, and evolutions in digital forensics – zeroing in on computers, social media, and the Internet of Things. They examine how advancements in technology are reshaping data collection and analysis methods. This episode provides valuable insights for how investigators can adapt to the complexities of modern digital evidence.
The discussion on social media highlights the difficulties investigators face due to the constantly-updating of platforms and strict privacy settings. With new applications like TikTok and WhatsApp becoming prevalent, traditional methods of collecting comprehensive social media histories are no longer feasible. Instead, investigators now need to conduct targeted searches and rely on data from mobile devices to understand a subject’s social media interactions more effectively.
The episode also covers the impact of the Internet of Things. Devices such as smart home assistants and security cameras can offer critical information for your case, but accessing this data can be challenging due to legal and technical barriers. Pete and Jeff spend time emphasizing the need for proper legal channels, such as subpoenas, to retrieve information from companies like Amazon, highlighting the increasing role of the Internet of Things in shaping forensic investigations.
