Doing anything online or digitally today leaves a record, whether it is conversations using messenger applications, saving, removing or moving files, or previously deleted emails. Digital forensics works to uncover digital activity that the perpetrator has previously tried to hide, delete or cover up.
#1. Tracing Digital Breadcrumbs
Often, the role of digital forensics analysists is to recover previously deleted data. You may think that after you delete a file, it is gone forever, but the truth is, deleting a file from your hard drive doesn’t mean that it has gone straight away. Instead, the computer will mark that place in its memory as available, but the original file will not be overwritten until a new file is saved to the same place.

In addition, the files that analysts gather are much more than simply the content produced by the file’s creator. Major file types such as emails and PDF’s, for example, contain a huge amount of information hidden in headers; this provides information such as when the file was sent, what service was used to send it, and much more. And, as an email moves from the sender to the recipient, any servers encountered along the way will add more information to the header. Digital Marketing Tips for Your Business
#2. Recovering Missing Data
According to analysts, most people’s devices are easy to look into when it comes to recovering missing data. When somebody has an authorized search warrant and the right tools for the job, even previously long deleted data on a computer or smartphone can be sorted and scraped through.

For example, saving files in ‘the cloud’ will make it difficult for analysts to recover files deleted there, while on the other hand, the growing trend of larger memory devices means that deleted files are less likely to be overwritten quickly.
Today, devices are tracking more data than ever before. As a result, analysts are finding new challenges in the sheer quantity of data that they may find on any one device. And, non-digital investigations are often still required to connect a device with a perpetrator.
