pnorth writes "A defunct payment gateway has exposed as many as 19,000 credit card numbers of US and UK consumers in a major worldwide breach. The data, held in Google cache, includes credit card numbers, CVVs, expiry dates, names and addresses. The credit card numbers are for accounts held with Visa, Mastercard, American Express, Solo, Switch, Delta and Maestro/Cirrus. Within the address bars of the cached pages are URLs of e-commerce sites that have become victims of the breach. They include clothing, science, health, sports and photo imaging stores. The cause appears to be 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."
