We conducted a similar study of HDDs and SSDs purchased on eBay in 2019. To discover what we found in this more recent study, download “Privacy for Sale: Data Security Risks in the Second-Hand IT Asset Marketplace.”

According to redemptions and loss recovery company Chargebacks 911, 72 percent of Americans own a smartphone, with users replacing them every 29 months. With all of these mobile phone replacements comes a hidden threat—the (often) sensitive data that’s left behind. Between May 2015 and August 2015, Blancco and Kroll Ontrack purchased a combined total of 122 second-hand hard disk drives, solid state drives and mobile devices sold in the U.S., Germany and the U.K. from popular online marketplaces. Here’s what we found:

  • 48 percent of hard drives and 35 percent of smartphones held residual data
  • Incomplete data sanitization methods had been performed on many of the devices
  • Recovered information included emails, sensitive company documents, photos and videos
