This software package from Italy claims to be able to crack IKE Aggressive Mode Pre-Shared Keys. Although this has not been verified it is always recommended to use the IPSec tunnels in "MAIN" mode instead of "Agressive" mode

Cain & Abel v2.5 beta35 for NT/2000/XP released
New features:
- IKE Aggressive Mode Pre-Shared Keys Cracker. The cracker works with both MD5 and SHA1 Hashes.
- Sniffer filter for IKE Aggressive Mode Pre-Shared Keys authentications. The sniffer collects all the parameters needed to crack a Pre-Shared Key used in IKE Aggressive Mode authentications (see RFC-2409 for details).
The IKE-PSK sniffer/cracker has been successfully tested using a Cisco VPN Client v4.0 and a Cisco PIX Firewall Version 6.3(1). Please let me know your results.
