January 20, 2020: Major Cybersecurity Incidents Unfold

# Lead Story: Citrix Vulnerability Exploited in the Wild

On January 20, 2020, the cybersecurity community was alerted to a critical vulnerability in Citrix Application Delivery Controller and Citrix Gateway, identified as CVE-2019-19781. This vulnerability allows remote, unauthenticated attackers to execute arbitrary code, and reports indicate that attackers began exploiting it almost immediately after its disclosure. The urgency of the situation is underscored by the U.S. Census Bureau's acknowledgment of a cyberattack linked to this vulnerability, although officials confirmed that no census data were compromised. As organizations scrambled to apply patches, the incident highlighted the persistent threat of exploitation in the current landscape. Citrix released updates by January 24, 2020, but the rapid exploitation of such vulnerabilities puts organizations at significant risk. CISA Cybersecurity Advisory
