While perusing the latest Risks Digest (22.04) article on the risks
associated with the proliferation of Nanny-Cams:
I back-tracked the URL to see if the author had any other interesting
papers to read.
In addition to a very interesting analysis of information leakage from
many of the popular web search engines, I came across a *very* interesting
on how line printers used as supposedly secure logging devices might
actually be subverted by getting it to accept control characters.
The author even gives the design for a simple hardware device to foil some
of those attacks.
