JiK, long ago and far away I once prepared a nasty little trap for would-be crackers.

On a Unix machine, I created a file with a name something like "Everybodys_Passwords_Unencrypted" -- not that name, of course, but you get the idea. Really attractive bait.

If you opened the file, your machine would be flooded with about 500,000 CODABAR barcodes, converted to hex. It would, in effect, overwrite your hard drive with the barcodes.

The trap was never triggered, and eventually I wiped that HD.

Sure wish I could remember how I did that!
