A modern photocopier is basically a computer with a scanner and printer attached. This computer has a hard drive, and scans of images are regularly stored on that drive. This means that when a photocopier is thrown away, that hard drive is filled with pages that the machine copied over its lifetime. As you might expect, some of those pages will contain sensitive information.
This 2011 report was written by the Inspector General of the National Archives and Records Administration (NARA). It found that the organization did nothing to safeguard its photocopiers.
Our audit found that opportunities exist to strengthen controls to ensure photocopier hard drives are protected from potential exposure. Specifically, we found the following weaknesses.NARA lacks appropriate controls to ensure all photocopiers across the agency are accounted for and that any hard drives residing on these machines are tracked and properly sanitized or destroyed prior to disposal. There are no policies documenting security measures to be taken for photocopiers utilized for general use nor are there procedures to ensure photocopier hard drives are sanitized or destroyed prior to disposal or at the end of the lease term. Photocopier lease agreements and contracts do not include a "keep disk"1 or similar clause as required by NARA's IT Security Methodology for Media Protection Policy version 5.1.
I don't mean to single this organization out. Pretty much no one thinks about this security threat.
