Really?... How about selecting all the tables from systables, then for

knowledge of the underlying applications and subtle enough that it
probably wouldn't be noticed until lots of damage had occurred. 

True ... but that's just causing arbitrary damage.  Most viruses have a
goal, even if it's just replicating.

Also, you assume that knowledge of the application would have to come
from the inside. The beauty of packages is that the table names are well
known.

The number of virus writers that know OS400 is pretty small, the number
of those that know BPCS, is probably even smaller.

'course, it only takes one :)
