Scary article in Wall Street Journal today

[Paul E Condon <pecondon@mesanetworks.net>]

Today in Wall Street Journal (pg 3 in US edition), there is an article
about hacker break-ins to computers via the internet. Mentioned as the
method of break-in are spyware called ZeuS, and Firefox browser, but
no mention of what OS are aflicted. 

I assume most of the affected computers are running some version of
Microsoft Windows, but is this also a threat to Linux, and, in
particular, Debian with Iceweasel? Where can I look to read a
discussion in more detail than this issue merits on this list?
e.g. How does ZeuS work? And what does it do?

TIA
