The biggest hole not plugged in your security is sitting in plain view, probably near your workstation, or at least its in a public area. If you’re at an institution that has done any upgrade to its copiers and printers within the last five years, the copier/printers being used are most likely housing the hidden threat underneath the plastic cover, a hard drive that copies and keeps records of every single copy made on the machine. The hard drive can hold a copy of every copy and the drive continues to write until it is full, and then the new data writes over the old copies.”]
