Aaron Rogan reports:

The home addresses of hundreds of Irish people have been published online in a data breach by a pharmaceutical company.

A cybersecurity expert said the error may leave people vulnerable to hackers as the company also shared email addresses that may be linked to other online accounts.

As part of a promotion for Aveeno moisturiser, Johnson and Johnson asked customers to fill in an online form. To prevent people from getting more than one free sample the form was checked against a text file of those who had already signed up. This file should have been encrypted and unreadable but was instead published on a website by the company that designed the promotion.
