8,000 An Post customers have been affected by a security breach

More than 8,000 customers have been affected.

An Post has announced today that some of its customers have been affected by a security breach. According to the Independent, the breach happened April 2016 and September 2017, and it involved those who asked for their address to be changed in between those dates. The publication states that thousands of customers who inputted their new details into the company's mail redirection service were affected, as their information was unknowingly submitted to a file containing details from customers who gave permission for their name and address to be used in external databases. More than 8,000 customers received a letter stating that their information had been breached.

"Your new address may have been updated on the records of companies you interact with, and you may have received letters from some companies to your new address instead of your old address. "Please be assured that Data Ireland never discloses names and addresses from the file they receive from An Post to direct marketing companies."

A spokesperson said: "The matter is now closed. We apologise for any inconvenience or concern that this error may have caused to the customers."
