On a UNIX/Linux system, anyone who is logged in as root or as the same user that the daemon is running as, can have complete access to the memory of the daemon and can thus (in principle) read the value of any variable. This could be done crudely with hexdump or strings and grep, or more sophisticatedly, by running gdb against the perl process.

Also they can (using strace for example) see all the data that is read from STDIN or any other file handle.

I don't know about Windows, but I would expect similar caveats to apply.
