UNC6671 Vishing-AiTM Campaign Targets Financial Services, Enterprise Cloud
- Engineer — Plan: Active group uses AiTM to bypass MFA on M365 and Okta; implement phishing-resistant FIDO2/hardware-key MFA and tighten Conditional Access or Okta device-trust policies to invalidate intercepted session tokens.
- SOC/IR — Act: Active campaign with mappable TTPs — hunt for anomalous Okta and M365 session activity (unexpected token origins, bulk SharePoint/OneDrive exfil) since May 2026 and pull the GTIG report for infrastructure IOCs tied to Redact, Pink, Helix, and Falcon brands.
- Leader — Act: Extortion group is actively hitting financial services, private equity, and professional services — if your org falls in these verticals, brief leadership this week on the campaign and verify that helpdesk impersonation and personal-device contact scenarios are covered in your security awareness program.
