From this report, you can view the number of messages with suspicious attachments. Attachments that use rare and anomalous filetypes, or attachments from untrusted senders that are either encrypted or contain scripts, pose a higher risk of malicious content.
Note: Untrusted senders are senders with no prior history with the recipient, or that have a low sender reputation.

Suspicious attachments graph
This graph shows messages broken down as follows:
- Encrypted—Number of messages with encrypted attachments. Encrypted attachments cannot be scanned for malware.
- Contain scripts—Number of messages that contain scripts. Certain documents contain malicious scripts that can harm your devices.
- Anomalous—Number of messages with anomalous attachments. Attachment types that are uncommon for your domain may be used to hide malicious content.
Note: You can hide lines in the graph by clicking on the legend. For example, click Contain scripts to hide this data. 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.

Compare current and historical data
To compare the current data to historical data, in the top right, from the Statistical analysis menu, select Percentile (not available for all Security dashboard charts). 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).
