Summary:
This event is generated when an attempt is made to access the Windows Security Accounts Manager (SAM) password file via a web request.

--
Impact:
Information gathering - An attacker tried to get the Windows password file

--
Detailed Information:
The SAM password file contains Windows logins which are NTLM or LANMAN hashes on Windows NT/2K/XP hosts.

The hash algorithms are weak and can be cracked within few minutes/hours if passwords are weak.

--
Affected Systems:
Windows NT 3.x and 4.0

--
Attack Scenarios:
If an attacker can get the real SAM file and is able to gain clear text passwords, the host can be compromised using the Administrator's login.

--
Ease of Attack:
Simple. Exploit scripts are available. The host may be already compromised depending on the password strength used on the server.

--
False Positives:
None Known

--
False Negatives:
None known

--
Corrective Action:
Change all Windows passwords.

Apply appropriate vendor supplied patches.

Upgrade to the latest non-affected version of the software.
