Rule:
--
Sid: 1776
--
Summary:
This event is generated when an attempt is made to use the MySQL 'show' command to garner a list of databases.
--
Impact:
Intelligence gathering. This may be the prelude to an attack against one the databases or the MySQL daemon.
--
Detailed Information:
This event is generated when the MySQL command 'show' is used to garner a list of MySQL databases being served by the MySQL daemon.
This connection can either be a legitimate telnet connection or the result of spawning a remote shell as a consequence of a successful network exploit.
--
Attack Scenarios:
A MySQL implementation may inappropriately respond to connections from any host external to the protected network. The atttacker may be able to query the daemon to gain a list of databases available, then continue to garner information from the databases.
--
Ease of Attack:
Simple.
--
False Positives:
This event may be generated by a legitimate user making a query to a MySQL daemon from an external source.
--
False Negatives:
None Known
--
Corrective Action:
Ensure that this event was not generated by a legitimate session then investigate the server for signs of compromise
Look for other events generated by the same IP addresses.
