Versa Director Zero Day Exploitation

Versa Director Zero Day Exploitation was conducted by Volt Typhoon from early June through August 2024 as zero-day exploitation of Versa Director servers controlling software-defined wide area network (SD-WAN) applications. Since tracked as CVE-2024-39717, exploitation focused on credential capture from compromised Versa Director servers at managed service providers (MSPs) and internet service providers (ISPs) to enable follow-on access to service provider clients. Versa Director Zero Day Exploitation was followed by the delivery of the VersaMem web shell for both credential theft and follow-on code execution.
