In Japan, lately it was on the news that stream from web cameras is exposed for public.
Poor settings of MFP were on the news, too. In many universities and small offices, MFP were connected to network without proper security settings like no password, no router, use of default password. Data in MFP were able to be viewed from outside.
Poor security settings of network equipment are problems not only in Japan but also in other countries.
Poor security settings of web cameras were reported from long ago.

And we still can see many web cams all over the world on Insecam.com (http://www.insecam.org/en/bytag/Office/?page=1).
Poor settings of MFP is common. "MFPs are often ignored as being as security risk at all" is addressed on BEU's Fundamentals of Security whitepaper.
