A standard Microsoft 365 user was escalated to Global Administrator in five minutes and 30 seconds during a live product launch demonstration by cybersecurity firm Huntress. The attack required no zero-day vulnerability—only the permissive identity configurations that plague enterprise tenants.

The demonstration, part of a showcase for Huntress’ new managed Identity Security Posture Management (ISPM) tool, laid bare the brittle reality of Microsoft 365 privilege controls. In under six minutes, a simulated standard user with no special permissions navigated a chain of misconfigurations to seize the highest administrative role in the tenant. The takeaway was blunt: identity posture is the new attack surface, and most organizations are failing to manage it.

The 330-Second Sprint to Total Control

Huntress engineers crafted a scenario that is alarmingly common in production environments. Starting from an ordinary user account—perhaps one belonging to a marketing intern or a contractor—the attacker exploited a series of layered missteps. First, a legacy application registration granted the user the ability to create a new service principal. That service principal was then assigned an over-privileged Microsoft Graph API permission, which allowed it to read and write all user profiles. From there, the attacker granted their own user account the Global Administrator role through the Microsoft Graph API call POST /roleManagement/directory/roleAssignments.

The chain took exactly 330 seconds on stage. No passwords were cracked. No software flaws were triggered. The entire escalation hinged on three interdependent misconfigurations: an unmanaged legacy app registration, excessive OAuth consent grants, and missing controls on role assignment requests.

Andrew Kaiser, lead researcher at Huntress, noted during the demonstration: “We didn’t hack anything. We just asked politely, and Microsoft 365 gave us the keys.”

Dissecting the Identity Posture Failure

The demonstration underscores what Microsoft engineers have been warning about for years: Entra ID (formerly Azure Active Directory) grants immense power through consent and role assignments, but few tenants enforce boundaries. The root causes fall into well-known categories:

  • Legacy application registrations: Older tenants often contain app registrations created before modern consent frameworks existed. These can carry broad permissions like Directory.ReadWrite.All and are rarely audited.
  • Unrestricted OAuth consent: Many organizations allow users to consent to applications requesting user-level permissions, but accidentally enable admin-level consent as well. A single misconfigured consent policy can open a pathway to tenant-wide access.
  • Over-permissioned service principals: Service principals—the identity objects for applications—are frequently assigned roles like Global Administrator during development and never scoped back. If a standard user can take control of such a principal, they inherit its full power.
  • Missing Privileged Identity Management (PIM) safeguards: Without PIM, role assignments are permanent and continuously active. In the Huntress demo, no just-in-time approval or multi-factor authentication challenge blocked the role grant.

These aren’t zero-days. They’re configuration debt accumulated through years of operational convenience outpacing security hygiene. Microsoft has documented each vector and provided hardening guides, but the shared responsibility model means tenants must act. Huntress’ performance simply proved how few do.

The Broader Identity Hardening Crisis

Huntress’ live demo arrives at a moment when identity has become the most contested territory in enterprise security. Microsoft’s own 2024 Digital Defense Report shows that 99% of identity-based attacks use legitimate credentials, often obtained via phishing or token replay. Once an attacker has a foothold with a low-privilege account, the real damage begins when they pivot across the tenant’s identity fabric.

A 2023 study by the Identity Defined Security Alliance found that 84% of organizations experienced an identity-related breach in the previous 18 months. The median privilege escalation path in a typical Entra ID tenant takes fewer than three steps, according to internal threat modeling by SpecterOps. Huntress’ 5.5-minute sprint aligns perfectly with those statistics—and raises a stark question: if a vendor can demonstrate it in a press briefing, how much faster could a motivated adversary move?

The answer, increasingly, is “a matter of seconds.” During red team engagements, security consultants regularly report gaining Global Admin within an hour of initial low-privilege access. The tools for automating these attack paths—like ROADtools, Stormspotter, and AzureHound—are open-source and widely available.

How Huntress’ Managed ISPM Aims to Close the Gap

The demonstration was not a random show of hacking prowess; it was the driver for Huntress’ new managed ISPM offering. The service continuously monitors Microsoft 365 and Entra ID tenants for identity posture drifts, dangerous misconfigurations, and suspicious permission assignments. It then either recommends or enforces remediation steps.

Key capabilities of the platform, as explained during the launch, include:

  • Continuous consent grant analysis: Automatically flags high-risk OAuth grants and app registrations with excessive permissions.
  • Privileged access monitoring: Detects when permanent Global Administrator assignments exist outside of PIM and alerts on new role assignments without required approvals.
  • Attack path simulation: Maps lateral movement paths from low-privilege accounts to critical roles, helping administrators cut off pivot points.
  • Identity hygiene scoring: Provides a simple numerical score that reflects overall security posture, similar to Microsoft Secure Score but focused purely on identity.

Managed ISPM is not unique—competitors like MDAG, CrowdStrike Falcon Identity Protection, and Varonis offer similar visibility—but Huntress is packaging it for the SMB and mid-market segment, where Microsoft 365 tenants often lack dedicated identity teams.

Practical Steps to Fortify Identity Posture Immediately

For organizations that can’t deploy a managed service overnight, Huntress’ demo serves as a free threat modeling exercise. Several immediate hardening actions can shut down the exact escalation path used on stage:

  1. Conduct a full OAuth consent audit: Review all enterprise applications and app registrations for permissions such as Directory.ReadWrite.All, RoleManagement.ReadWrite.Directory, and User.ReadWrite.All. Remove or restrict any that aren’t actively used.
  2. Enforce user consent settings: Under Entra ID > Enterprise applications > User settings, set “Users can consent to apps accessing company data on their behalf” to No. Use admin consent workflows for exceptions.
  3. Implement Privileged Identity Management (PIM): Convert all static Global Administrator assignments to eligible roles requiring activation. Enforce MFA and approval flows for activation.
  4. Restrict role assignment to designated administrators: In Entra ID role settings, configure Microsoft.Directory/roleAssignments/roleManagement.readWrite.all to only privileged administrators.
  5. Remove legacy app registrations: Identify and delete or update app registrations created before modern authentication enforcement. An easy query via Microsoft Graph: GET /applications?$filter=createdDateTime lt 2020-01-01
  6. Enable Multi-Factor Authentication universally: Use Conditional Access policies to require MFA for all users, especially for any operation that modifies roles or permissions.
  7. Monitor role assignment events: Set up alerts in Microsoft Sentinel or Microsoft Defender for Cloud Apps that trigger on any high-privilege role assignment addition.

Microsoft’s Response and the Shared Responsibility Model

Microsoft has not commented directly on the Huntress demonstration but has long acknowledged that identity posture is a customer responsibility. A Microsoft spokesperson reiterated: “The security of your tenancy is a shared effort. We provide the tools—like PIM, conditional access, and identity protection—but customers must configure and audit them.”

This stance is consistent with how all cloud providers operate, yet the Huntress demo exposes a critical gap: the default configurations are not secure. When a fresh Microsoft 365 tenant is created, user consent is enabled, and legacy permission models persist. Microsoft has made strides with security defaults for new tenants—mandating MFA and blocking basic auth—but these defaults do not retroactively fix existing tenants or prevent all privilege escalation paths.

The Azure Active Directory Connect cloud sync team has also been working on reducing the attack surface for hybrid identity, but on-premises synchronization misconfigurations remain a common entry point. In many environments, a single synchronized user with broad on-prem privileges can become Global Admin in the cloud with minimal effort.

The Clock Is Ticking

Huntress’ 5.5-minute escalation is not an outlier; it’s a representative sample of what happens when identity posture goes unmanaged. The demonstration serves as a stark warning to the thousands of businesses that treat Microsoft 365 as an email and file storage platform, ignoring the complex identity web beneath.

As more attackers trade malware for identity-based tactics, the speed of privilege escalation will only increase. Automated tools like TokenTactics and GraphRunner can now execute similar attacks in under two minutes when target tenants are heavily misconfigured. The difference between a minor user compromise and a full tenant takeover is increasingly a matter of whether the identity plumbing has been inspected in the past quarter.

For Windows-centric organizations, the lesson is clear: identity hardening must move from an annual compliance checkbox to a continuous operational priority. Whether through a managed ISPM service like Huntress’, Microsoft’s own suite of tools, or rigorous manual audits, the goal is to ensure that no standard user can become Global Admin in the time it takes to brew a cup of coffee.
