- Information about this document
The /etc/passwd file on Unix systems contains password information. An attacker who has accessed the etc/passwd file may attempt a brute force attack of all passwords on the system.
An attacker may attempt to gain access to the etc/passwd file through HTTP, FTP, or SMB. Typically this is done through one of the CGI scripts installed on the server, so this event may be seen in conjunction with other events of that type.

Examine the URL accessed and evaluate if the access attempt could have been successful. If so, consider the system compromised and all passwords exposed. Although this event is not the result of a specific vulnerability, you should take steps to ensure that HTTP, FTP, and SMB file shares do not contain vulnerabilities that could allow remote access to the /etc/passwd file.
