(Bloomberg) -- Attunity Ltd., a company that manages and safeguards data, left internal files exposed on the internet for clients including Ford Motor Co., and the Toronto-Dominion Bank, in the latest example of sensitive information being publicly accessible on the web. Researchers at UpGuard Inc., a cybersecurity company, found more than a terabyte of data left unsecured by Attunity last month on Amazon Web Services cloud-computer servers, according to a report they published Thursday. The centerpiece was a large collection of Attunity files including administrative and employee passwords to various systems, extensive employee email backups, a roadmap to the company’s virtual network and personal information about Attunity’s employees. Attunity removed public access to the buckets the day after UpGuard informed the company about the breach in May, but it took several weeks before Attunity asked the cybersecurity company more detailed questions about the data exposure, according to Vickery. Attunity said current evidence indicated UpGuard was the only entity that accessed the data.
