A privileged account is any account with elevated access, like admin rights, the ability to modify configurations, view sensitive data, or move laterally across systems. When that access exceeds what the role actually requires, it becomes over-privileged.
According to the 2025 Verizon Data Breach Investigations Report, credential abuse was the initial access vector in 22% of breaches last year. Stolen credentials were involved in 88% of basic web application attacks.
The why is simple.
As Anton Chuvakin, security advisor at Google Cloud's Office of the CISO, puts it: "Over-privileged user accounts are the low-hanging fruit attackers are looking for, and they will always take the path of least resistance."
Attackers love stale accounts because they look legitimate. When a threat actor compromises a dormant admin account and starts moving through your environment, the activity doesn't immediately raise flags.
In 2024, attackers compromised a Snowflake vendor account that lacked multi-factor authentication (MFA). That one forgotten, under-secured access point led to breaches across more than 100 organizations, including AT&T and Ticketmaster. No exploit. No zero day. Just a door that was left open.
Snowflake was enterprise-scale, but the attack vector works just as well against a 50-person company running on shared IT admin credentials.
Chances are, you have at least one of these in your environment right now.
Offboarding processes are inconsistent, and in the chaos of someone leaving, full account deprovisioning often gets skipped or half-finished. Teams disable the account but leave permissions intact.
These accumulate over time. Shared credentials are especially problematic because no single person owns them, and when no one owns something, no one audits it.
You grant vendor access for a project and never revoke it once the work is done. It's the digital equivalent of a contractor keeping a keycard they were never asked to return. Third-party risk isn't theoretical. The 2025 Verizon DBIR found that breaches involving external partners doubled year-over-year, now accounting for 30% of all of them.
Organizations design service accounts for convenience, not security, and permissions pile up as a result. They operate silently in the background, with nobody reviewing whether their privileges still make sense.
Service accounts outnumber human users 5:1, and most have more access than they need.
Ownership of accounts becomes unclear as teams change. Access reviews happen inconsistently, if at all. And security teams are typically focused on active threats and active users, not on the ghost accounts collecting dust in the directory.
Security tools that prioritize novelty and anomaly don't always catch the risk hiding in plain sight.
For MSPs, this problem compounds fast. You're managing identity sprawl across dozens of client environments simultaneously, with no consistent offboarding process across clients. The ghost accounts aren't just collecting dust in one directory—they're collecting dust in all of them.
Getting this under control requires consistency. A few things that move the needle:
If an account has been inactive for 30, 60, or 90 days, flag it. For an MSP managing multiple clients, that means building account review into your quarterly check-ins.
If you can't answer "Who owns this?" or "Why does it still exist?" then you've got risk, pal. A simple spreadsheet mapping every privileged account to a name and a business reason is a better starting point than most organizations have.
If an account that's been dark for six months tries to authenticate at 2 am, that's a red flag. Investigate it.
Privilege management is an ongoing discipline that should be built into how you manage identity security across the board.
It's also a compliance issue. Regulations like HIPAA, GDPR, and SOX mandate strict access controls, and over-permissioned accounts are a fast path to an audit finding or a fine.
The hacker in the hoodie makes for a better movie poster, but forgotten accounts are the vulnerability that doesn't need to pick a lock because the door is already open.
Huntress Managed ITDR and Managed ISPM are built to help with this problem: detecting suspicious identity activity and identifying stale and over-privileged accounts.
The biggest threat in your environment might not be someone trying to break in, but a key that was never taken back.
