"When you upgrade to a new mobile phone or computer, how you discard your device impacts your security. Most people think that when they reformat their hard drive or restore their mobile device to its factory default settings, everything gets erased -- but that's not usually the case." [emphasis mine]
This statement above is what got my full attention when I watched a short video over at Udemy on the safe disposal of hard drives. This course is part of a very digestible video series on Mobile Cybersecurity Awareness that was created by Eric Schwartzman of the Center for Digital Innovation at Howard Industries. I highly recommend watching it (and the other 11 lectures in this series) as essential learning for every mobile device user. It won't even take up too much of your time; as you can see in the screenshot below, it's less than 4.5 minutes.
In the video, Schwartzman shared that MIT had actually conducted a study using over 160 hard drives that were disposed or resold to determine if these were really cleaned out effectively. They were able to recover confidential information like credit card numbers, medical records, social security numbers. Yikes.
