What Is Metadata and Why Does It Matter to Businesses?
Metadata is often described as “data about data”. It is the invisible layer of information attached to digital content, i.e. emails, Word documents, PDFs, spreadsheets, photographs, that describes how, when and by whom the file was created. Most people only ever see the visible content, but underneath lies a wealth of additional detail.
For example, a photo shared externally might contain GPS coordinates and the type of device used. Also, a Word document may carry the author’s name, the company domain, editing history and even internal file paths. Emails include headers that record the sending IP address, the mail server used, and the route taken.
Therefore, as highlighted by these examples, this invisible data matters because criminals do not always need to break into a system to learn about it. Metadata provides them with an information-rich trail they can use to understand how a business operates, who works there, and what technologies are in place. For UK businesses already facing high levels of phishing and fraud, this exposure creates another avenue for attack.
