A year in cyber security: looking back at 2017

TEISS Head of Consulting Jeremy Swinfen Green looks back at 2017 – and takes a peek into next year.

We had data breaches in abundance of course. Nothing particularly new there although there were interesting features to some of them.


Equifax, the credit reporting agency, suffered a huge cybersecurity incident, affecting 143 million consumers in the US (well over half the adult population). The data of some 15 million UK customers was also reported as being compromised.

The hackers are thought to have stolen names, Social Security numbers, birth dates and addresses: information that taken together can be used to steal identities and set up fraudulent loans.
