In recent months, Google has tracked three suspected Russia-linked cyber espionage clusters, dubbed UNC6293, UNC7005, and UNC5976. These clusters have been identified through Google's efforts to monitor phishing campaigns and authentication exploitation tactics that are being used to target researchers, academics, government officials, think-tank analysts, and defense sector personnel across Europe and the United States. The clusters have been linked to a number of malicious operations, including phishing campaigns, malware distribution, and OAuth phishing operations. To protect against these tactics, individuals and organizations must be aware of the common tactics used by these clusters and take steps to prevent their exploitation.
Google's Threat Intelligence Group has tracked three suspected Russia-linked cyber espionage clusters: UNC6293, UNC7005, and UNC5976. These clusters have been identified through phishing campaigns and authentication exploitation tactics targeting researchers, academics, government officials, and defense sector personnel in Europe and the US. UNC6293 is a sub-cluster of APT29 (ICE RELIC), linked to initial access operations and app password phishing. UNC7005 is a related cluster connected to ICE RELIC, with lower technical sophistication but a wider toolkit. UNC5976 focuses on military, aerospace, defense industrial base, and NGO targets, concentrating on Ukraine and Armenia. Common tactics used by these clusters include phishing campaigns, authentication exploitation, and malware distribution. Google recommends protecting against these tactics by not setting app passwords, revoking existing ones, and treating suspicious OAuth prompts.
In recent months, Google's Threat Intelligence Group has tracked three suspected Russia-linked cyber espionage clusters, dubbed UNC6293, UNC7005, and UNC5976. These clusters have been identified through Google's efforts to monitor phishing campaigns and authentication exploitation tactics that are being used to target researchers, academics, government officials, think-tank analysts, and defense sector personnel across Europe and the United States.
The oldest and most precisely attributed cluster, UNC6293, is believed to be a sub-cluster of the group known as APT29, also referred to as ICE RELIC. This group has been linked to initial access operations and has been identified through its consistent impersonation of US State Department officials to run app password phishing. The technique involves convincing a target to set a specific app password on their account, which the attacker already knows, and then using it to log in without triggering two-factor authentication.
UNC7005, a related but separate cluster, has been identified by Microsoft as STORM-2945 and is believed to be connected to ICE RELIC as well. This group operates with lower technical sophistication and worse operational security than UNC6293, but compensates by using a wider toolkit. UNC7005 has been linked to a number of phishing operations, including app password phishing, device code phishing against both Microsoft and WhatsApp, malware distribution, and OAuth phishing operations.
The most distinct cluster, UNC5976, has been identified by Google and is believed to focus on military, aerospace, defense industrial base, and NGO targets, concentrating geographically on Ukraine and Armenia. This cluster has been identified through its use of dedicated infrastructure and OAuth phishing operations, which are more automated. The group has been linked to a number of malicious operations, including the distribution of a malicious Excel plugin called HEADRUSH.
Google has identified a number of common tactics used by these clusters, including the use of phishing campaigns to target individuals, the use of authentication exploitation tactics to gain access to personal accounts, and the use of malware to exfiltrate data. The clusters have also been linked to a number of compromised legitimate accounts, which are being used to phish the target's contacts.
In order to protect against these tactics, Google has issued a number of recommendations, including not setting app passwords for anyone who asks, revoking existing ones that don't recognize, checking WhatsApp's linked devices list, and treating any OAuth authorization prompt from an unsolicited message as suspicious. High-risk individuals are also advised to consider Google's Advanced Protection Program, which blocks app password creation entirely.
The use of sophisticated phishing campaigns and authentication exploitation tactics by Russia-linked cyber espionage clusters is a concerning development in the world of cybersecurity. These clusters have been identified through Google's efforts to monitor phishing campaigns and authentication exploitation tactics, and have been linked to a number of malicious operations. In order to protect against these tactics, individuals and organizations must be aware of the common tactics used by these clusters and take steps to prevent their exploitation.
