Pro Tips for conducting a Social Media Investigation
1. Google & Bing Cross referencing
When conducting a Social media investigation always cross reference your subjects pedigree information across a range of search engines like google and bing and of course, social media websites like Facebook.
2. Look Your Subject Up On Social Media
Social media profiles provide strong information on a subject’s lifestyle, Interest and Locations as well as historical data which can be an absolute goldmine, think pictures of a target on a specific day, placing them somewhere they should not be. Of course as Social media is now so mainstream, be prepared that your targets may be more internet savvy and will likely make attempts to hide their information as much as possible.
Big social media sites like Facebook provide all the privacy tools to ensure a user does not feel too public but privacy controls are confusing to a lot of folks so always expect the unexpected and keep exhausting all avenues.
3. Constant Surveillance via Facebook Groups
Facebook has changed somewhat over the years and one area which has grown quickly and seems to be a mainstay is; Groups. Groups can be a strong tool for Investigators, with the ability to identify a target, discover their interests, potentially identify their favorite groups within Facebook and you can join the group and keep an eye on the target and their interactions.
Providing the group is a public group you can request to join and you can monitor your target long term or even develop communications with them.
4. Live Data Changes, Find it and File it, FAST
When you find something important, before you do anything else, capture that data from your live site and protect your Investigation. Live sites can change so quickly, do not be caught out with this kind of school boy error, Live Data Changes, Find it and File it, Fast.
