INTRODUCTION
IKEForce is a command line IPSEC VPN brute forcing tool for Linux that allows group name/ID enumeration and XAUTH brute forcing capabilities.

INSTALL
Requires the pyip, pycrypto and pyopenssl modules installed, but other than that it's only standard libs.
pyip is the most likely lib that you won't have, install it with 'pip install pyip'
USAGE
./ikeforce.py [target] [mode] -w /path-to/wordlist.txt [optional] -t 5 1 1 2
Example (find all AM transforms):
./ikeforce.py 192.168.1.110 -a -s 1
Example (enum mode):
./ikeforce.py 192.168.1.110 -e -w groupnames.txt -s 1
Example (brute mode):
./ikeforce.py 192.168.1.110 -b -i groupid -u dan -k psk123 -w passwords.txt -s 1
Options:
-h, --help
show this help message and exit
-w WORDLIST, --wordlist=WORDLIST
Path to wordlist file
-t TRANS, --trans=TRANS
[OPTIONAL] Transform set: encryption type, hash type, authentication type, dh group (5 1 1 2)
-e, --enum
Set Enumeration Mode
-a, --all
Set Transform Set Enumeration Mode
-b, --brute

-y IDTYPE, --idtype=IDTYPE
[OPTIONAL] ID Type for Identification payload. Default
is 2 (FQDN)
-s SPEED, --speed=SPEED
[OPTIONAL] Speed of guessing attempts. A numerical
value between 1 - 5 where 1 is faster and 5 is slow.
Default is 3
-l KEYLEN, --keylen=KEYLEN
[OPTIONAL] Key Length, for use with AES encryption
types
-v VENDOR, --vendor=VENDOR
[OPTIONAL] Vendor Type (cisco or watchguard currently
accepted)
--version=VERSION [OPTIONAL] IKE verison (default verison 1)
Transform Set Helper (Non-exhautive):
| Enc Type (1) | Hash Type (2) | Auth Type (3) | DH Group (4) |
|---|---|---|---|
| 1 = DES | 1 = HMAC-MD5 | 1 = PSK | 1 = 768-bit MODP group |
| 2 = IDEA | 2 = HMAC-SHA | 2 = DSS-Sig | 2 = 1024-bit MODP group |
| 3 = Blowfish | 3 = TIGER | 3 = RSA-Sig | 3 = EC2N group on GP[2^155] |
| 4 = RC5-R16-B64 | 4 = SHA2-256 | 4 = RSA-Enc | 4 = EC2N group on GP[2^185] |
| 5 = 3DES | 5 = SHA2-384 | 5 = Revised RSA-Sig | 5 = 1536-bit MODP group |
| 6 = CAST | 6 = SHA2-512 | 64221 = Hybrid Mode | |
| 7 = AES | 65001 = XAUTHInitPreShared |

Version 0.1
- Improved timeout in enum mode
- Fixed server exit trace errors
- Added automated transform set enumeration using the -a flag
- Improved transform code and several other parts of the client/handler code.
- Improved/added full connect mode (-c) which allows to negotiation of a full IPSEC connection. The ESP keys are provided after successful negotiation
- Fixed a bug in brute mode
- Added a check for XAUTH bypass (CVE-2015-0760)
