Administrator privilege virus

In GPOs linked to OUs containing member servers and workstations in each domain, the DA group should be added to the following user rights:. This will prevent members of the DA group from logging on to member servers and workstations.

Auditing should be configured to send alerts if any modifications are made to the properties or membership of the DA group. These alerts should be sent, at a minimum, to users or teams responsible for AD DS administration and incident response. You should also define processes and procedures for temporarily populating the DA group, including notification procedures when legitimate population of the group is performed. As is the case with the EA and DA groups, membership in the Administrators BA group should be required only in build or disaster-recovery scenarios.

There should be no day-to-day user accounts in the Administrators group with the exception of the local Administrator account for the domain, if it has been secured as described in Appendix D: Securing Built-In Administrator Accounts in Active Directory. When Administrators access is required, the accounts needing this level of access should be temporarily placed in the Administrators group for the domain in question. Although the users are using the highly privileged accounts, activities should be audited and, preferably, performed with a user performing the changes and another user observing the changes to minimize the likelihood of inadvertent misuse or misconfiguration.

When the activities have been completed, the accounts should immediately be removed from the Administrators group. Administrators are, by default, the owners of most of the AD DS objects in their respective domains. Membership in this group may be required in build and disaster recovery scenarios in which ownership or the ability to take ownership of objects is required.

Additionally, DAs and EAs inherit a number of their rights and permissions by virtue of their default membership in the Administrators group. Default group nesting for privileged groups in Active Directory should not be modified, and each domain's Administrators group should be secured as described in Appendix G: Securing Administrators Groups in Active Directory , and in the general instructions below.

Remove all members from the Administrators group, with the possible exception of the local Administrator account for the domain, provided it has been secured as described in Appendix D: Securing Built-In Administrator Accounts in Active Directory.

Members of the domain's Administrators group should never need to log on to member servers or workstations. In one or more GPOs linked to workstation and member server OUs in each domain, the Administrators group should be added to the following user rights:.

At the domain controllers OU in each domain in the forest, the Administrators group should be granted the following user rights if they do not already have these rights , which will allow the members of the Administrators group to perform functions necessary for a forest-wide disaster recovery scenario:. Auditing should be configured to send alerts if any modifications are made to the properties or membership of the Administrators group.

These alerts should be sent, at a minimum, to members of the team responsible for AD DS administration. Alerts should also be sent to members of the security team, and procedures should be defined for modifying the membership of the Administrators group.

Specifically, these processes should include a procedure by which the security team is notified when the Administrators group is going to be modified so that when alerts are sent, they are expected and an alarm is not raised. Additionally, processes to notify the security team when the use of the Administrators group has been completed and the accounts used have been removed from the group should be implemented. NOTE] When you implement restrictions on the Administrators group in GPOs, Windows applies the settings to members of a computer's local Administrators group in addition to the domain's Administrators group.

Therefore, you should use caution when implementing restrictions on the Administrators group. Although prohibiting network, batch and service logons for members of the Administrators group is advised wherever it is feasible to implement, do not restrict local logons or logons through Remote Desktop Services.

Blocking these logon types can block legitimate administration of a computer by members of the local Administrators group. The following screenshot shows configuration settings that block misuse of built-in local and domain Administrator accounts, in addition to misuse of built-in local or domain Administrators groups.

Note that the Deny log on through Remote Desktop Services user right does not include the Administrators group, because including it in this setting would also block these logons for accounts that are members of the local computer's Administrators group.

If services on computers are configured to run in the context of any of the privileged groups described in this section, implementing these settings can cause services and applications to fail. Therefore, as with all of the recommendations in this section, you should thoroughly test settings for applicability in your environment. Generally speaking, role-based access controls RBAC are a mechanism for grouping users and providing access to resources based on business rules.

In the case of Active Directory, implementing RBAC for AD DS is the process of creating roles to which rights and permissions are delegated to allow members of the role to perform day-to-day administrative tasks without granting them excessive privilege. RBAC for Active Directory can be designed and implemented via native tooling and interfaces, by leveraging software you may already own, by purchasing third-party products, or any combination of these approaches. In the simplest RBAC implementation, you can implement roles as AD DS groups and delegate rights and permissions to the groups that allow them to perform daily administration within the designated scope of the role.

In some cases, existing security groups in Active Directory can be used to grant rights and permissions appropriate to a job function. For example, if specific employees in your IT organization are responsible for the management and maintenance of DNS zones and records, delegating those responsibilities can be as simple as creating an account for each DNS administrator and adding it to the DNS Admins group in Active Directory.

The DNS Admins group, unlike more highly privileged groups, has few powerful rights across Active Directory, although members of this group have been delegated permissions that allow them to administer DNS and is still subject to compromise and abuse could result in elevation of privilege.

In other cases, you may need to create security groups and delegate rights and permissions to Active Directory objects, file system objects, and registry objects to allow members of the groups to perform designated administrative tasks. For example, if your Help Desk operators are responsible for resetting forgotten passwords, assisting users with connectivity problems, and troubleshooting application settings, you may need to combine delegation settings on user objects in Active Directory with privileges that allow Help Desk users to connect remotely to users' computers to view or modify the users' configuration settings.

For each role you define, you should identify:. In many environments, manually creating role-based access controls for administration of an Active Directory environment can be challenging to implement and maintain. If you have clearly defined roles and responsibilities for administration of your IT infrastructure, you may want to leverage additional tooling to assist you in creating a manageable native RBAC deployment.

For example, if Forefront Identity Manager FIM is in use in your environment, you can use FIM to automate the creation and population of administrative roles, which can ease ongoing administration. If you use Microsoft Endpoint Configuration Manager and System Center Operations Manager SCOM , you can use application-specific roles to delegate management and monitoring functions, and also enforce consistent configuration and auditing across systems in the domain.

If you have implemented a public key infrastructure PKI , you can issue and require smart cards for IT staff responsible for administering the environment. In other cases, it may be preferable for an organization to consider deploying third-party RBAC software that provides "out-of-box" functionality.

When choosing between native solutions and third-party products, you should consider the following factors:. Privileged identity management PIM , sometimes referred to as privileged account management PAM or privileged credential management PCM is the design, construction, and implementation of approaches to managing privileged accounts in your infrastructure.

Generally speaking, PIM provides mechanisms by which accounts are granted temporary rights and permissions required to perform build-or-break fix functions, rather than leaving privileges permanently attached to accounts. Whether PIM functionality is manually created or is implemented via the deployment of third-party software one or more of the following features may be available:.

One of the challenges in managing privileged accounts is that, by default, the accounts that can manage privileged and protected accounts and groups are privileged and protected accounts. If you implement appropriate RBAC and PIM solutions for your Active Directory installation, the solutions may include approaches that allow you to effectively depopulate the membership of the most privileged groups in the directory, populating the groups only temporarily and when needed.

If you implement native RBAC and PIM, however, you should consider creating accounts that have no privilege and with the only function of populating and depopulating privileged groups in Active Directory when needed. Appendix I: Creating Management Accounts for Protected Accounts and Groups in Active Directory provides step-by-step instructions that you can use to create accounts for this purpose.

Law Number Six: There really is someone out there trying to guess your passwords. Your account type is displayed below your user name. If your account type is Administrator , then you are currently logged on as an administrator. If your account type is not Administrator , then you cannot log on as an administrator unless you know the user name password for another account on the computer that is an administrator. If you are not an administrator, you can ask an administrator to change your account type.

Windows 7 More Type the user name and password for your account in the Welcome screen. Need more help? Join the discussion. The main problem is that a high-privilege Windows native application eventvwr. Discovery and detailed analysis of this recent UAC bypass technique was posted by enigma0x3 here only a few months ago. The fourth section of the command simply executes the Fareit malware again.

This may just be a fail-safe mechanism in case the attempt to execute it in high privilege does not work. Macro malware attacks have been around for a long time, mainly because they are very effective at social engineering schemes. Over time, they have become more aggressive and creative in evading detections for themselves and their payloads, and this current example is another advance development that we will surely start to see in other variants.

Sharing this kind of information to the public always has its pros and cons. For the security community, it can serve as a good heads-up to plan and mitigate its bad effects.
