-Instrumentation for the second option of attack added (additionally to
triggerring the shell): figure out address of our own small malicious program
'indicator', located in /bin, and write inside main function of compress42.c
this address to file 'indaddress' (similar to writing addresses of the shell
and system() to files). As a result of attack ncompress will jump to
/bin/indicator (instead of jumping into shell as in the first attack)

- File 'indaddress' is generated
