SUMMARY The Cybersecurity and Infrastructure Security Agency (CISA) and the Multi-State Information Sharing & Analysis Center (MS-ISAC) conducted an incident response assessment of a state government organization’s network environment after documents containing host and user information, including metadata, were posted on a dark web brokerage site. Analysis confirmed that an unidentified threat actor compromised network administrator credentials through the account of a former employee—a technique commonly leveraged by threat actors—to successfully authenticate to an internal virtual private network (VPN) access point, further navigate the victim’s on-premises environment, and execute various lightweight directory access protocol (LDAP) queries against a domain controller.[1]…
