Statewide, MoDOT maintains thousands of computer devices. Keeping those computers safe from outside threats is a 24-hour responsibility that relies on the latest security measures.

For the fourth quarter of fiscal year 2026, MoDOT received a total of 21,545 emails containing malicious content (links and/or attachments) that were delivered to user inboxes. Of those 21,545 delivered emails, seven recipients clicked on the links or attachments. Among those seven clicks, four were blocked at the time of click, while the remaining three were permitted.

This quarter saw a decrease in the number of malicious emails delivered to user inboxes. The current high is 30,536 malicious emails delivered in the third quarter of FY 2026. Out of the 90 days in this quarter, there were only five days when MoDOT did not receive a malicious email directly in a user’s inbox. These emails originated from 16 campaigns, involving seven threat actors.

MoDOT continues to emphasize cybersecurity and provide training for all department computer users. The cybersecurity oversight team works to identify areas of vulnerability and deploy solutions to reduce risk. In addition, MoDOT utilizes the Office of Administration’s network firewall services, endpoint cybersecurity detection, and remediation services to provide increased cyber protection.

Purpose of the Measure:

Measurement and Data Collection:

The incident data for this measure is captured from MoDOT's e-mail security platform.
The target for this measure is zero clicks.
