In Cisco VPN client configurations, which field is stored as enc_GroupPwd and is encrypted but can be cracked easily?

• A. GroupPwd
• B. enc_GroupPwd
• C. Password
• D. UserPassword

Answer: (B)

The key idea is that credentials in a Cisco VPN client configuration can be stored in different forms, and one of them is an encrypted version of the group password. The field named enc_GroupPwd holds this encrypted form of the Group Password. It’s designed to hide the password, but the encryption used in older Cisco VPN client configs is weak, with a static key, so an attacker can recover the plaintext password from the file relatively easily using offline cracking. That’s why this field is described as encrypted but crackable. In contrast, the plaintext GroupPwd (if present) would be readable directly, and the other fields (like Password or UserPassword) pertain to different credentials or storage methods. The important takeaway is that enc_GroupPwd is the gated, encrypted form of the group credential, and its weak protection means it can be cracked with minimal effort.
