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

For the second quarter of fiscal year 2026, MoDOT received a total of 17,147 emails containing malicious content (links and/or attachments) that were delivered to user inboxes. Of those 17,147 emails, 10 recipients clicked on the links or attachments. Among those 10 clicks, five were blocked at the time of click, while the remaining five were permitted.

This quarter saw the largest number of malicious emails delivered to user inboxes since this measure was first tracked. The previous high was 16,206 malicious emails delivered in the fourth quarter of FY 2025. Out of the 91 days in this quarter, there were only eight days when MoDOT did not receive a malicious email directly in a user’s inbox. These emails originated from 40 campaigns involving six 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 address risk. In addition, MoDOT utilizes the Office of Administration’s network firewall services, endpoint cybersecurity detection and remediation services to provide increased protection.

Purpose of the Measure:

This measure reports MoDOT's average click rate on malicious email links and attachments. Using this measure, MoDOT can compare performance to previous quarters and make adjustments in the security training program to reflect the observed trend.

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.
