It doesn't work that way. Attackers don't check if you are using "Omega", they check if you are vulnerable. There is simply no difference if you are hiding framework indicators here.

Well - unless there is a targeted attack _against you_. In this case the attacker will search for known vulnerabilities in Omega and maybe even try to come up with some new ones. Having source helps the attackers here, but then again, it has helped researchers fix the vulnerabilities too. So it's a mixed blessing.
