![]() ![]() On Windows systems, you can find a list of Local User Accounts under Local Users and Groups in the computer management menu. ![]() Privileges can be Local or Domain, which determines the scope of access the User account has. How privileges are created and delegated in Windows systemsĪ privilege in Windows operating systems is the authorization delegated to a User account or Group that allows access to system resources, objects, and tasks. All these activities are crucial to ensure a business can function by keeping systems and software running. Privileged accounts allow Users to make system and software configuration changes, execute administrative tasks, create and modify accounts, deploy software, back up data, install security patches, enable interactive logins, and of course, access privileged data. Some types of non-human high privileged accounts are application accounts used to run services requiring specific permissions. A privileged account can be human or non-human. It’s common to have shared privileged access used by a department or group of Users to access applications or systems. Privileged accounts enable administrative or specialized levels of access based on higher levels of authorizations. Privileged accounts are distinguished from standard User accounts that represent human identities, such as an Active Directory User account with a password to restrict access. They ensure the IT team can manage the organization’s systems, infrastructure, and software, and they enable employees to access the data that enables them to make critical business decisions. Privileged accounts are at the core of every business. This foundation will help you understand the strategies cyber criminals use when attacking Windows systems so you know where to focus your defenses. Here's an example of elevation of a privilege attack using EternalBlue privilege escalation exploit:Įxample of when an attacker has pwned a system with NT Authority\System Privilege escalation focuses on privileged accounts and accessīefore we start getting into the mechanics of Windows privilege escalation attacks, we must first understand what privileged accounts are used for, the different types of privileges on Windows systems, and how they work. And, you’ll identify opportunities to increase Windows privilege management to reduce your risk of a cyberattack. By viewing privilege escalation through the lens of a hacker you’ll see how attackers exploit security vulnerabilities to achieve their goals. In this blog, you’ll learn how an attacker escalates privileges on Windows systems using a step-by-step process. With higher-level privileges, an attacker can move freely around the network without detection.Įxamples illustrating the difference between vertical and horizontal privilege escalation Horizontal privilege escalation, the more common method, is when an attacker gains access to another credential on the network with higher privileges than the initial one used to gain their foothold.For example, they might add the compromised account to the local administrator group. They then look for ways to increase their privileges using the same account. Vertical privilege escalation, sometimes referred to as privilege elevation, is when an attacker compromises a user account that has limited permissions on a system.To achieve those goals, an attacker employs a variety of strategies to escalate privileges: They’re looking for access to business-critical systems so they can deploy ransomware, threaten shutdown, and demand financial payment. They’re looking for more sensitive data they can resell on the Dark Web. ![]() That password may enable certain privileges, for example, it may only unlock data stored locally on a laptop. Let’s say an attacker successfully steals a User’s password and gains access to their account. With Domain Administrator access, they own the entire network.Īn attacker may employ a variety of strategies to escalate privileges With NT Authority\System access, attackers have full access to one system. From a hacker’s perspective, privilege escalation is the art of increasing privileges from initial access, which is typically that of a standard user or application account, all the way up to administrator, root, or even full system access. Privilege escalation is also one of the most common techniques attackers use to discover and exfiltrate sensitive valuable data. For example, users may need access to troubleshoot a technical problem, run a quarterly financial report, or install a program. For trusted users, privilege escalation allows expanded access for a limited time to complete specific tasks. Privilege escalation is the process by which a user with limited access to IT systems can increase the scope and scale of their access permissions. ![]()
