"...Judging by the growing number of Linux and other
operating system machines exploited every month, there are an
increasing number of "poorly administered" Linux boxes out there.
Figures from Attrition up until April show that around 300 Linux
boxes are exploited every month. This is less than the figure for
NT boxes, but it is still worrying.
Paul Rogers, network security analyst at MIS, pointed out that
security in any environment comes down to security policy. "You do
find poorly administered Linux boxes, just as you find poorly
administered DNS servers, and just as you find poorly administered
machines running any other operating system."
The risk the Remote Shell attack poses is reduced, said Rogers,
"because Linux-based Trojans and viruses need more social
engineering to get executed because of the way, for example, Linux
mail clients are written"."
