Yes postings have been sparse lately – things getting busy so alas. Anyway, very short (but rather alarming) note from Wired about copiers. Though I knew most copiers now used digital technology of some sort, I had no idea they actually contained full-blown hard drives that store your copies. The exact reason why they need hard drives to copy documents, and why the data needs to remain on the drives, is a bit of a mystery to me, and something the article doesn’t go into. I’d had always just assumed that the image information was stored somewhere temporarily and disappeared when you finished copying. Apparently not. Anyway, here’s a brief excerpt:
most digital copiers manufactured in the past five years have disk drives – the same kind of data-storage mechanism found in computers – to reproduce documents. As a result, the seemingly innocuous machines that are commonly used to spit out copies of tax returns for millions of Americans can retain the data being scanned.
If the data on the copier’s disk aren’t protected with encryption or an overwrite mechanism, and if someone with malicious motives gets access to the machine, industry experts say sensitive information from original documents could get into the wrong hands.
I guess someone, somewhere, will be selling add-on kits for copiers relatively shortly…
[…] example is copiers and the tip comes from David Ma’s techblawg in a post called “from the ‘another security headache’ department” that highlights a Wired article on the storage capabilities of […]
