In June 2022, Montrose Environmental Group experienced a ransomware attack that targeted its laboratory network, disrupting testing services and delaying the delivery of certain lab results. The company characterized the threat actors as highly sophisticated and responded by engaging law enforcement and cybersecurity experts. Affected systems were suspended while remediation efforts were initiated, with priority given to restoring operations to minimize service interruptions. Cloud‑based enterprise systems and backups were reported to remain unaffected during the incident. The organization anticipated only limited operational impact from the attack. It committed to notify clients and regulatory bodies if any third‑party data access was identified during the ongoing investigation. The incident highlighted the firm’s focus on maintaining data integrity and its preparedness to coordinate with external authorities. These details constitute the publicly known facts about Montrose Environmental Group’s profile and its recent cybersecurity event.
