CISA Alert: APT Actors Chaining Vulnerabilities against Government Organizations and Critical Infrastructure
The U.S. Department of Homeland Security Cybersecurity and Infrastructure Security Agency (CISA) has published an alert on recently-observed activity involving an advanced persistent threat actor exploiting multiple legacy vulnerabilities in combination with a newer privilege escalation vulnerability – CVE-2020-1472 – in Windows Netlogon. CISA explains this is a commonly-used tactic, known as “vulnerability chaining,” in which multiple vulnerabilities are exploited in the course of a single intrusion to compromise a network or application.
