You can use the spoofing report to view the number of messages that show evidence of potential spoofing.
View the spoofing report
- Click Security.
- Click Dashboard.
- In the bottom-right corner of the Spoofing panel, click View Report.
This graph shows messages broken down by Similar domain, Display name, and Domain name:
- Similar domain—Number of incoming messages from domains that look visually similar to trusted domains
- Display name—Number of messages where the message sender's name is a name in your G Suite directory, but the mail is not from your company's domains or domain aliases
- Domain name—Number of unauthenticated messages (SPF or DKIM) pretending to be from your domain
Note: You can hide lines in the graph by clicking on the legend. For example, click Display name to hide data related to display-name spoofing. This is especially useful if one line overlaps another.
Using the drop-down menus above the graph, you also customize the graph to provide details only about certain types of messages:
Classification: All, Clean, Spam, Phishing, Malware, Suspicious
All—Include all messages.
|Domain||Choose the domain for your report.|
Customize the report to view data from Today, Yesterday, This week, Last week, This month, Last month, or Days ago (up to 180 days); or enter a Start date and End date. Click Apply after you set the date range.
Note: For this report, data is displayed only for the last 31 days. For example, if you set the parameters for up to 60 days, the data in the report is cut off at 31 days.
To generate a spreadsheet with the graph’s data, click Export Sheet. A spreadsheet corresponding to the data in the graph will be generated and saved to your My Drive folder.
Compare current and historical data
To compare the current data to historical data, in the top right, from the Statistical analysis menu, select Percentile. You’ll see an overlay on the chart to show the 10th, 50th, and 90th percentile of historical data (180 days for most data and 30 days for Gmail data). Then, to change the analysis, at the top right of the chart, use the menu to change the overlay line.
To view more details about spoofing on specific dates, click any data point in the graph. For example, you can view data for this report by Subject, Recipient, Sender, IP address, and more.
