NOMINATIONS NOW OPEN

​Prelude to a HACK

It all sounds harmless to post and share information, but to attackers these are great clues and can form the basis of a hack. Social engineering is a technique used as a foundational step to collect information for open sources.

A keynote from the CSO Perspectives Roadshow (Sydney 15th and Melbourne 22nd March) will feature an expert on this subject – Brett Webber from Sententia. Brett is an acknowledged thought leader and practitioner of deep analysis of open source data.

In a normal year, Brett is engaged by various law enforcement agencies, law firms and financial services companies to find all the things that we didn’t expect to be available online, or indeed we thought we had deleted.

Lots of Breadcrumbs

Should I want to conduct electronic surveillance of a targeted person or entity – I would arrange such an engagement with Brett. (For purely ethical business reasons of course!)

Brett uses Big Data tools and methodologies to collect large data sets to find the breadcrumbs of useful data, thus there is a critical and mandatory requirement for strong capabilities across a number of domains including:

  • Meta Data management
  • Unstructured data analysis
  • eDiscovery
  • Advanced Online Searching
  • Forensics
  • Social Media Data Mining.

Data is collected from multiple online sources and coalesced, then the real fun begins. The data is analysed against the requirements of the particular piece of work to develop valuable information for the client.

To analyse these large data sets of unstructured data from disparate data sources, companies like Sententia apply deep business and technical domain knowledge, and just a little hint of white magic.

Seeing patterns

This line of work typically produces a high proportion of ‘false’ positives, thus there is both a degree of inspiration and perspiration.

A demonstrated history of being able to eliminate false positives suggests that there is no luck involved, rather deep levels of skill with technology and methodology are involved in what to some may be a dark science.

Brett noted that: “In our investigations we are always surprised with what, and how much of it, we find. We bring expertise and context to large data sets which we obtain from a multitude of open sources. Enterprise search and analysis solutions enable us to join the dots. Often the data tells a very different story to that being spun elsewhere.”

Different disciplines in search are used including geospatial, social network analysis, keywords and search terms to augment supervised and unsupervised data analysis. Brett remarked that ‘key word’ search alone is quite limited.

The Power of Forensic Analytics

The acid test is how this actually works in the court of law. As I talked to Brett he also shared that in order to be used as evidence in court - insights from pattern matching has found critical items in many cases. In turn these new insights, led to discovery of facts and the overturing of claim matters.

Just one simple example, from Brett ……

“We recently found a key witness to an assault that had a particularly high media profile. The witness was found via an exchange of related material on a blog. Locating and contacting the witness in a manner which facilitated them being willing to give evidence was a key outcome, which assisted our client in turning the case to their advantage”.
