What is a Privileged Account and Why Attackers Target Them

Not all accounts are created equal. In every organisation, a small number of accounts have the power to change system configurations, access all data, create or delete other accounts, and override security controls. These are privileged accounts — and they are the single most valuable target for cyber attackers.

If an attacker compromises a standard user account, they can see that person’s email and files. If they compromise a privileged account, they can see everything — and change anything. This is the difference between a minor incident and an existential breach.

What Makes an Account “Privileged”?

A privileged account is any account that has elevated permissions beyond what a standard user needs for day-to-day work. These accounts can:

• Install or remove software across the network
• Create, modify, or delete other user accounts
• Access all files and data — including sensitive financial, HR, or customer records
• Change security settings — disable firewalls, alter audit logs, modify access policies
• Move laterally across systems without triggering the access restrictions that apply to normal users

Privileged accounts exist in many forms that organisations often fail to track:

• Domain Administrator accounts in Active Directory
• Root accounts on Linux/Unix servers
• Global Administrator in Microsoft 365 and Azure AD
• Database administrator (DBA) accounts
• Service accounts used by applications to communicate with other systems
• Emergency or break-glass accounts kept for disaster recovery
• Local admin accounts on individual workstations

Why Attackers Prioritise Privileged Accounts

Cybercriminals and nation-state actors do not break into organisations by brute-forcing the front door. They find a way in — usually through phishing or exploiting a vulnerability — and then escalate privileges. The initial foothold is just the beginning. The real objective is always a privileged account.

In the SolarWinds attack (2020), attackers compromised a software update mechanism to gain initial access to thousands of organisations. But the damage was done when they escalated to privileged accounts within those environments — accessing email systems, identity infrastructure, and security tools. Without privileged access, the initial compromise would have been contained.

The Colonial Pipeline ransomware attack (2021) was triggered by a single compromised VPN account that had administrative privileges. The attackers did not need to exploit sophisticated vulnerabilities — they logged in with valid credentials to an account that had far more access than it should have had.

According to CrowdStrike’s 2024 Global Threat Report, 80% of breaches involve compromised credentials, and privilege escalation is present in nearly every major incident investigation.

The Privilege Problem at Scale

Most organisations dramatically underestimate how many privileged accounts they have. A mid-sized company with 500 employees might have 100 standard user accounts for every one human administrator — but they might also have 200+ service accounts, local admin accounts on every workstation, and shared credentials for legacy systems that nobody has audited in years.

This sprawl of unmanaged privilege is what makes Privileged Access Management (PAM) essential. PAM is the discipline of identifying, securing, monitoring, and controlling all privileged access in your environment. It is not a single product — it is a combination of policies, processes, and tools.

Why This Matters

A compromised privileged account gives an attacker the same power as your most trusted administrator. They can exfiltrate data, deploy ransomware, destroy backups, and cover their tracks — often within hours. The cost of a breach involving privileged credentials is significantly higher than one involving standard accounts, because the blast radius is the entire organisation.

Insurance underwriters now routinely ask about privileged access controls. Organisations without PAM fundamentals face higher premiums, policy exclusions, or outright denial of cyber insurance coverage.

What to Do Now

• Ask IT to produce a list of all accounts with administrative or elevated privileges — including service accounts
• Determine whether privileged accounts are separated from day-to-day user accounts (they should be)
• Check whether MFA is enforced on all privileged accounts without exception
• Find out if there are any shared admin credentials in use
• Ask when the last review of privileged access was conducted

Evidence to Collect

• A current inventory of all privileged accounts (human and service)
• Documentation showing that admin accounts are separate from standard user accounts
• Proof that MFA is enforced on privileged access
• Records of the most recent privileged access review, including who approved continued access
• Any logs showing privileged account usage over the past 90 days

Common Mistakes

• Using admin accounts for daily work. Administrators who read email, browse the web, and perform admin tasks from the same account are creating a direct attack path. A phishing link clicked in an admin session compromises the entire environment.
• Not knowing how many privileged accounts exist. If you cannot list them, you cannot secure them. The first step is always discovery.
• Treating service accounts as low risk. Service accounts often have the highest privileges and the weakest controls — no MFA, passwords that never rotate, and no one monitoring their activity.
• Believing small organisations don’t need PAM. Attackers target organisations of all sizes. A ten-person company with an unprotected admin account is easier to breach than a large enterprise with PAM controls in place.
