How did this happen? The company failed to properly configure their Rsync backups, wrote CSO’s Steve Ragan.Later that week, WikiLeaks released a trove of information on the CIA’s hacking tools, including descriptions of how the agency targeted iPhones, Android phones, Samsung smart TVs, and routers.On March 17th medical records of 26 million patients at 2,700 medical practices in Britain were potentially compromised.
