Russian State-Sponsored Phishing Campaign Targeting Zimbra Collaboration Suite — Denver Operations Footprint
Russian state-supported cyber actors are conducting an active phishing campaign targeting users of Zimbra Collaboration Suite, a widely deployed email and collaboration platform used across enterprise and BPO environments. Denver hosts approximately 360,000 contact-center, back-office, and knowledge-worker seats, making it a high-density target where credential compromise could disrupt communications, access controls, and service-delivery continuity. Operations leaders should verify Zimbra patch levels and MFA enforcement, issue phishing-awareness reminders to staff, and confirm whether the Panduit IntraVUE network infrastructure monitoring tool — flagged in the same signal cluster — is properly segmented and access-controlled given its network visibility scope. Affected regions: Denver, Dfw, Okc
