Hi,

since it's start about 20 years ago Windows NT supports (finegrained)

ACLs, including the permission "execute file".

In their very finite wisdom Microsoft but decided back then to have
this permission set on EVERY file a user creates (and assumes it is
set on local and remote file systems which dont support ACLs).

The result: on Windows, malware can run everywhere (and since CWD
alias "." is in the path, can be started everywhere)!



Keep these coming...these are very interesting reads...thanks Stefan.
