Ry Crozier of iTnews reports:
A defunct payment gateway has exposed as many as 19,000 credit card numbers, including up to 60 Australian numbers.
The discovery by a local IT industry worker was made by mistake and appears to be caused by a known issue with the Google search engine, in which the pages of defunct web sites containing sensitive directories remain cached and available to anyone.
The cached data, viewed by iTnews, includes 22,000 credit card numbers, including CVVs, expiry dates, names and addresses.
Up to 19,000 of these numbers could be active.
“It looks like the site might have been a payment processing gateway that handled credit card transactions for a bunch of websites before it went belly-up,” the worker speculated.
