Viewing Detected Messages | Trend Micro Service Central

Views:

Gain intelligence about the context of a spear-phishing attack by investigating a wide array of information facets. Review the email headers to quickly verify the email message origin and how it was routed. Investigate attacks trending on your network by correlating common characteristics (examples: email subjects that appear to be your Human Resource department or fake internal email addresses). Based on the detections, change your policy configuration and warn your users to take preventive measures against similar attacks.

Go to Detections > Detected Messages.
Specify the search criteria.
See Detected Message Search Filters.

Detected Message Search Filters

The following table explains the basic search filters for querying suspicious messages. To view the detected messages, go to Detections > Detected Messages.

Note:

Search filters do not accept wildcards. Deep Discovery Email Inspector uses fuzzy logic to match search criteria to email message data.

Filter	Description
Threat type	Select All or a threat type from the list. For details, see Threat Type Classifications.
Risk level	Select All or the email message risk level.
Action	Select All or an action from the list. This is the action that Deep Discovery Email Inspector applies on email messages when a scanning condition is matched in a policy rule. For more information, see Policy Rules. Note: In BCC mode and SPAN/TAP mode, the action is always Monitoring only.
Period	Select a predefined time range or specify a custom range.

Specify the information to filter.

Filter	Description
Sender	Specify the sender email address.
Email header (To)	Specify a primary recipient email address in the email header.

Direction	Specify the message direction.
Rule	Specify a rule name.
Email header (From)	Specify the author email address in the email header.
URL	Specify a URL.
Source IP	Specify the MTA IP address nearest to the email sender. The source IP is the IP address of the attack source, compromised MTA, or a botnet with mail relay capabilities. A compromised MTA is usually a third-party open mail relay used by attackers to send malicious email messages or spam without detection. Note: The Source IP search filter requires an exact-string match. Deep Discovery Email Inspector does not use fuzzy logic to match search results for the source IP address.
File name	Specify an attachment file name.
Data identifier	Specify a data identifier name.
YARA rule name	Specify the name of a YARA rule.
Recipient	Specify a recipient email address. Only one address is allowed.
Threat name	Specify the threat name provided by Trend Micro. The dashboard widgets and the Detections tab provide information about threat names. For information about threat discovery capabilities, see Scanning / Analysis.
Sender IP	Specify the sender IP address. If you deploy Deep Discovery Email Inspector as an edge MTA in your network, the sender IP address is the public IP address of the external MTA nearest to your network. If you deploy Deep Discovery Email Inspector as a non-edge MTA in your network, the sender IP address is the IP address of the MTA nearest to the edge MTA relay server. Note: The Sender IP search filter requires an exact-string match. Deep Discovery Email Inspector does not use fuzzy logic to match search results for the sender IP address.
Policy	Specify a policy name.
DLP template	Specify a DLP template name.
YARA rule file name	Specify the name of a YARA rule file.
Password-protected attachment	Select email messages that contain a password-protected file.
