A security issue has been identified in YubiKey Manager GUI which could lead to unexpected privilege escalation on Windows. If a user runs the YubiKey Manager GUI as Administrator, browser windows opened by YubiKey Manager GUI may be opened as Administrator which could be exploited by a local attacker to perform actions as Administrator. Under this circumstance, some browsers like Edge for example, have additional mitigations to prevent opening as Administrator.

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] Analysis also focused on the victim’s Azure environment, which hosts sensitive systems and data, as well as the compromised on-premises environment. Analysis determined there were no indications the threat actor further compromised the organization by moving laterally from the on-premises environment to the Azure environment.
