[GPSCC-chat] Heartbleed is real. Do something real.

Fri Apr 11 12:52:20 PDT 2014

People should also know that there may be additional security gaps in ATMs
and Point Of Sale terminals due to their owners' slow response to the need
to do away with using Windows XP. For instance, the last time I went to
Round Table Pizza a couple of weeks ago, the screen saver on their POS
terminal still said "Windows XP". Chase signed a contract for another year
of support from MS for Win XP for their ATMs, but I can only assume that
everyone else will no longer have support for Win XP after early April
2014.  Good luck on that one too.
