Russian Clusters UNC6293/UNC7005/UNC5976 Abuse OAuth Flows in Espionage Campaigns
- Engineer — Plan: OAuth consent-flow abuse by APT29-linked clusters is a real attack surface for any organization using third-party OAuth integrations; audit configured OAuth app permissions and enforce stricter conditional access policies to reduce the social-engineering foothold these groups exploit.
- SOC/IR — Act: Three active Russian clusters are running persistent campaigns against high-value sectors using OAuth flow hijacking and captive-portal redirects — pull Google’s full IOC list, hunt for anomalous OAuth token grants or device-code auth attempts since mid-2025, and tune detections for captive-portal redirect chains tied to UNC7005 TTPs documented by Reliaquest and Microsoft.
- Leader — Plan: If your organization falls in academia, aerospace/defense, government, or think tanks, queue a targeted user-awareness briefing on OAuth and device-code phishing before next quarter; the APT29 lineage of UNC6293 elevates this beyond routine phishing and warrants a conversation with your security team about protective intelligence coverage.
