FORT GEORGE G. MEADE, Md. , –
U.S. Cyber Command and the Department of Homeland Security - Cybersecurity and Infrastructure Security Agency released eight files attributed to the Russian Foreign Intelligence Service (SVR)/APT 29 to enable public defense against further compromise.

Hunt Forward operations are one way the U.S. defends forward against adversaries in cyberspace. These missions generate insights to understand the adversary, enable defense through sharing information with partner nations, departments, agencies and the cyber security community, and provide opportunities to disrupt, degrade or defeat malicious cyber activity when needed.
The samples released include variants of GoldMax, GoldFinder, Sibot and a new variant of a known webshell. Russian actors were using the variants of malware in combination on the targeted networks.
