Process name faker for linux/BSD/Unix
To compile and get the binary:
gcc pnfaker.c -o pnfaker
To execute it:
./pnfaker "/bin/ls -la" /usr/bin/nc -vn 192.168.1.124 443
In the example above we open a netcat connection against host 192.168.1.124 port 443, but we disguise it as "ls -la" if somebody lists that machine processes.
