All news with #azure entra id tag

🔒 Researchers disclosed a max-severity vulnerability in Microsoft Entra ID that allowed attackers to request and reuse internal Actor tokens to impersonate any user, including Global Administrators, across tenants. The issue stemmed from a legacy Azure AD Graph API that failed to validate the originating tenant, enabling cross-tenant impersonation without triggering MFA, Conditional Access, or audit logs. Microsoft patched the flaw, tracked as CVE-2025-55241, and rolled a global fix but experts warn that lack of historical visibility leaves uncertainty about past exploitation.

🔍 Cyber threat group Scattered Spider has been linked to a new campaign targeting financial services, according to ReliaQuest. The attackers gained access by socially engineering an executive and abusing Azure AD self-service password reset, then moved laterally via Citrix and VPN to compromise VMware ESXi. They escalated privileges by resetting a Veeam service account, assigning Azure Global Administrator rights, and attempted data extraction from Snowflake and AWS. The activity contradicts the group's retirement claims and suggests regrouping or rebranding.

🔐 Microsoft has completed a global rollout enforcing multifactor authentication (MFA) for Azure Portal sign-ins across 100% of tenants as of March 2025. The rollout follows an initial enforcement announcement in May 2024 and prior warnings to Entra global admins to enable MFA to avoid access disruptions. Microsoft says this step strengthens account defenses and will be followed by mandatory MFA for Azure CLI, PowerShell, SDKs, and APIs in October 2025. The company cites internal research showing MFA dramatically reduces account takeover risk.

🔐 Microsoft Threat Intelligence reports that the financially motivated actor Storm-0501 has refined cloud-native techniques to rapidly exfiltrate and delete data in hybrid Azure environments. The group leveraged on-premises footholds—using tools such as Evil-WinRM and a DCSync attack—to compromise an Entra Connect server and identify a non-human synced Global Admin account without MFA. With that account the attackers registered a threat actor-owned federated tenant as a backdoor, escalated Azure privileges, and proceeded to mass-extract data and remove resources and backups before extorting victims through compromised Microsoft Teams accounts. Microsoft has updated Entra ID behavior, released Entra Connect 2.5.3.0 to support Modern Authentication, and recommended enabling TPM, enforcing MFA, and other hardening controls.
