In late 2011, we published our analysis
of a bunch of USB keys we'd bought at a lost property auction.
We took $400 (about £260) to a public transport utility's annual auction and came home with 57 USB keys containing 4400 files.
We didn't find any Wikileaks-type information - there were no criminal plots, no rush orders for F-35
strike fighters, and no intelligence data from the diplomatic community.
But we did get several surprises, which we wrote about
at the time:
* 66% of the keys had one or more malware infections.
* Many of the keys contained personal and work-related files.
* Not a single one of the 4400 files was encrypted.
