Why (and how) threat actors target your Active Directory. Microsoft Active Directory tops the list of targets that attackers go after in the enterprise. It’s generally the core identity and access management solution for accessing resources in many environments, so Active Directory compromise can lead to catastrophic consequences. It can allow attackers to access sensitive information, launch ransomware attacks, escalate privileges, establish persistent threats, and more. Why is Active Directory an attractive target for hackers? Active Directory environments contain a wealth of information for an attacker. In Active Directory, a threat actor can gain information about all users, groups, and permissions for the environment. It’s the central authentication service for the enterprise. So, if an attacker can penetrate this core service, the old cliché is true: they gain access to the "keys to the kingdom.” What tools and tactics do attackers use to target Active Directory? Attackers can use many basic types of attacks to steal or crack weak or reused Active Directory passwords, including phishing attacks, brute force attacks, and password spray attacks. Note some of the popular tools attackers commonly use to compromise AD environments: What makes Active Directory an easy target? Several things can combine to make an Active Directory an easy target. These break down into several different categories, including the following: Weak and reused passwords – End users left without policies for proper password enforcement tend to choose weak passwords that are easy to remember. Even with a strong password policy in place, they may still reuse passwords leading to further risk. These weak and compromised passwords are easy targets for brute force and dictionary attacks. Scale and complexity of Active Directory infrastructure – Active Directory may have thousands of objects, OU's, service accounts, and many other components. There are lots of potential attack routes for hackers to exploit. Failure to audit activities in the AD environment – Many organizations don't have the tools needed to monitor and audit Active Directory properly, leaving unmonitored vulnerabilities in place. Unnecessary user accounts that are not maintained – There may be gaps in offboarding processes and unused service accounts that allow accounts to become stale or have dangerous passwords configured and set to not expire. Excessive privileges assigned to user or service accounts – Instead of using role-based access control, users or service accounts may be given excessive permissions to ease provisioning. These accounts can be particularly dangerous if compromised. However, all user accounts should be protected, as skilled attackers can escalate their privileges from any account. How to make your Active Directory a difficult target As we all know, proper security is about layers. It takes a multi-faceted approach. Organizations must do the basics, including proper security hygiene, configuration management, and lifecycle tasks for offboarding, etc. Businesses also need to think about the following to make their Active Directories more difficult to compromise: Boost your Active Directory security today Securing an Active Directory environment is a combination of best practices, diligence in lifecycle and housekeeping processes, and using the right technical tools to secure the environment. While this approach is not infallible, it makes Active Directory a more secure and less desirable as a target for attackers. Organizations can bolster the security of their Active Directory infrastructure with third-party solutions like Specops Password Policy, which extends the default capabilities of Active Directory password policies using existing Group Policy Objects (GPOs). In addition, the breached password protection feature provides a way to continuously scan for over four billion passwords known to have been compromised.

Daily Brief Summary
Microsoft Active Directory is a prime target for attackers due to its central role in enterprise identity and access management.
Compromising Active Directory allows attackers to access critical information, escalate privileges, and deploy ransomware.
Attackers employ various methods including phishing, brute force, and password spraying to steal credentials.
Common vulnerabilities include weak, reused passwords, complex infrastructure, and insufficient auditing of AD activities.
Organizations often fail to maintain proper offboarding, leaving unused accounts vulnerable and putting excessive privileges at risk.
Best practices for strengthening Active Directory security involve enhancing password policies, implementing rigorous configuration management, and improving lifecycle processes.
Specops Software offers tools like Specops Password Policy to enhance default Active Directory password policies and detect breached passwords.
Continuous security enhancements and expert consultations are recommended to mitigate risks and make Active Directory a less attractive target for hackers.
