    i have followed your tutorial with exact same version of flash player which is vulnerable. but the staging of the attack doesn’t come. it is stuck at “sending swf”, i have read some forums and used windows/exec payload and set CMD calc.exe just to see if it works, still that doesn’t work, i have turned my firewall off, deactivated the antivirus, made a fresh install of firefox and then i tried again, but still i amn’t able to solve it. please help me out! thanks in advance
