Enterprise cloud giant Cloudera has pulled several of its cloud storage servers offline, despite initially claiming the servers were “open by design,” after a security researcher found sensitive internal files inside.

Chris Vickery, director of risk research at security firm UpGuard, found the cloud storage servers — known as buckets — hosted on Amazon Web Services in late July. The data largely contained legacy Hortonworks data from prior to its $5.2 billion all-stock merger with Cloudera in January 2019.
