This week we've had yet another reminder of the poor state of online security after Adidas admitted its US website had been hacked. In the process, data for millions of consumers was stolen.

As Bloomberg reports, Adidas discovered "an unauthorized party" had gained access to its servers and stolen data on June 26. Customers were informed yesterday and the full extent of the breach is still being investigated. So far, Adidas believes contact information, usernames, and encrypted passwords were taken for "a few million consumers."

Thankfully, it looks as though payment information including credit card details, and health data were not accessed. However, if you've purchased products from the Adidas US websites there's a chance your contact details have been leaked and Adidas will be contacting you. In the meantime, it's worth changing the password for your Adidas account as a precaution.

In a statement the company said, "Adidas is committed to the privacy and security of its consumers' personal data. Adidas immediately began taking steps to determine the scope of the issue and to alert relevant consumers. Adidas is working with leading data security firms and law enforcement authorities to investigate the issue."

Hopefully Adidas shares all the details of what happened once its investigation is concluded. It also seems likely customers will be offered some form of Identity Theft protection for an extended period of time in response to their details being stolen.
