Somewhere in most Azure tenants sits a small, often overlooked list of accounts holding Global Administrator or equivalent privileged roles, each one capable of undoing every other security control in the environment in a matter of minutes. These roles do not need a sophisticated exploit to become a disaster. They just need to fall into the wrong hands, once, briefly.
Global Administrator is a master key, not just a job title
A Global Administrator in Azure AD can reset any password, add new privileged accounts, disable multi-factor authentication requirements, and reach into every connected service across the tenant, from email to file storage to line-of-business applications. This level of access is sometimes necessary for genuine administrative work, but it is granted far more often than it is actually needed, usually because assigning the broadest role is simply quicker than working out the narrower one that would have done the job just as well, and nobody circles back to tidy it up afterwards.
A thorough Azure pen testing engagement specifically maps every privileged role assignment in a tenant, because this is precisely where the real business risk concentrates, far more than in any individual misconfigured setting elsewhere. Finding that twelve accounts hold Global Administrator rights, when perhaps three genuinely need it, is the kind of finding that reshapes an entire security programme once it is properly understood.
Privileged roles are exactly what attackers hunt for first
Once an attacker gains any foothold in an Azure environment, their very next move is almost always to identify which accounts hold privileged roles, because compromising one of those accounts turns a minor incident into complete tenant takeover within minutes. Phishing campaigns increasingly target IT staff and administrators specifically for this reason — the return on a single successful phish against a Global Administrator vastly exceeds the effort of trying to compromise dozens of standard user accounts individually, one at a time.
William Fieldhouse has seen how quickly this concentration of privilege turns catastrophic.
“We found seventeen accounts with Global Administrator rights in one tenant during an assessment, and when we asked why, the honest answer was that it had simply been the path of least resistance every time someone needed elevated access for a one-off task. Seventeen doors to the entire kingdom, left unlocked, because closing them properly each time felt like more effort than it was worth.”
— William Fieldhouse, Director of Aardwolf Security Ltd
Seventeen is an extreme example, but the underlying pattern is depressingly common: privileged access granted for convenience, rarely reviewed afterwards, and almost never reduced back down once the original task is finished. Each one of those accounts is a single point of failure for the entire tenant, and most businesses have no accurate current count of how many they actually have.
Audit your privileged roles before an attacker does it for you
Run a proper audit of every account holding Global Administrator or similarly powerful roles in your tenant, and apply the principle of least privilege without exception, no matter how inconvenient it feels in the short term. Aardwolf Security’s Azure assessments map this exposure clearly and are frequently cited by clients as a reason we are recommended as the best pen testing company for cloud-focused security work generally. Get in touch to have your privileged roles properly and independently reviewed.
