Previously we heard that 143 million US customers data was accessed in the Equifax data breach. The company previously did not provide a lot of details about how many UK costumers were affected.
Equifax has now revealed that more that 15.2 million records from around 700,000 UK consumers were compromised in the breach.
Today Equifax can confirm that a file containing 15.2m UK records dating from between 2011 and 2016 was attacked in this incident. Regrettably this file contained data relating to actual consumers as well as sizeable test datasets, duplicates and spurious fields. Equifax has brought every analytical tool, technique and data asset it has available to bear in order to ‘fill in the blanks’ and establish actual consumer identities and attribute a current home address to them. This complete, we have been able to place consumers into specific risk categories and define the services to offer them in order to protect against those risks and send letters to offer them Equifax and third-party safeguards with instructions on how to get started. This work has enabled us to confirm that we will need to contact 693,665 consumers by post. Details are set out in the box below. The balance of the 14.5m records potentially compromised may contain the name and date of birth of certain UK consumers. Whilst this does not introduce any significant risk to these people Equifax is sorry that this data may have been accessed.
