Iranian government-sponsored threat actors have been blamed for compromising a U.S. federal agency by taking advantage of the Log4Shell vulnerability in an unpatched VMware Horizon server.
The details, which were shared by the U.S. Cybersecurity and Infrastructure Security Agency (CISA), come in response to incident response efforts undertaken by the authority from mid-June through mid-July 2022.
“Cyber threat actors exploited the Log4Shell vulnerability in an unpatched VMware Horizon server, installed XMRig crypto mining software, moved laterally to the domain controller (DC), compromised credentials, and then implanted Ngrok reverse proxies on several hosts to maintain persistence,” CISA noted.
