Vulnerable Active Directory Scripts (Part 1)

By Ashwin Venugopal -

 




About

There are different types of Vulnerable Active Directory Scripts that make AD environment vulnerable to various kinds of attacks. Every script is written in PowerShell. 

ACL

In Active Directory, this is used to establish an Organizational Unit and configure Access Control Lists (ACLs). The script's first two lines import the Active Directory module, which sets the current location to the AD disc and offers the cmdlets required to operate with AD.   

The script then defines the "SetAcl" function, which has four parameters: $right, $inheritance, $for, and $to." The username of the user for whom the ACL is being set is represented by the $for parameter, the name of the OU to which the ACL is being applied is represented by the $to parameter, and the right being granted to the user is represented by the $right parameter. To indicate if the access rule should be inherited by child objects, use the $inheritance argument. Additionally, the function contains an extra input called $extendedRight that can be used to define an extended right.

AnonymousLDAP

In an AD system, this script is used to set the anonymous LDAP bind user and enable anonymous LDAP access. The script's initial line imports the Active Directory module, which offers the cmdlets required to work with AD. 

ASRPRoasting

This PowerShell command can be used to change an AD user account's settings. This command specifically sets the "DoesNotRequirePreAuth" value of the user account "korin.z" to true using the Set-ADAccountControl cmdlet.

The "DoesNotRequirePreAuth" attribute determines whether or not the user account pre-authentication step is required by the Kerberos authentication protocol. The user can authenticate to the domain without supplying any evidence of their prior domain authentication when this attribute is set to true, indicating that the user account does not require pre-authentication. Because anyone can authenticate to the domain as the designated user without having to provide a working password or other kind of identity verification, this lowers security.

Note- This command only affects the account on the Kerberos authentication protocol, and does not affect other authentication protocols such as NTLM or LDAP. 

Conclusion

This topic talks about different Vulnerable Active Directory Scripts and their uses.

  Azure Sentinel Workbooks Several ready for use templates are provided by the Azure Sentinel that can be used to create your own workbook and then modify them as needed for Contoso. Most of the data connectors it uses to ingest data come with their own workbooks, but better insight can be obtained by simply looking into the data that is being ingested by using tables and visualizations, including bar and pie charts. You can also make your own workbook easily by using this data from the beginning instead of using the predefined templates. Workbook Page You can easily access the workbook page from the Azure Sentinel from the navigation pane which consists of the: Workbook header- You can add a new workbook and review the saved workbooks as well as templates that are available on the workbook page. Templates section- You can access existing workbook templates on the Templates tab. You can save some of the workbooks for quick access and they will appear on the My Workbooks tab.  From the

The loaf balancer also offers an option of DirectServerReturn which if configured, can help in directing the traffic from the DBMS VM to the SAP application layer directly to the application layer without routing through the load balancer. But, if it isn't configured, then the return traffic to the SAP application layer is routed through the load balancer. You can also use Azure Load Balan

Work with String Data Using KQL Statements

  Extract Data from Unstructured String Fields Unstructured string fields often contains the Security log data and requires parsing to extract data. There are multiple ways of pulling information from string fields in KQL and the two primary operators used are extract and parse.  Extract It gets a match for a regular expression from a text string. You can convert the extracted substring to the indicated type.  Arguments regex- A regular expression. captureGroup- A positive int constant indicating the capture group to extract. 0 stands for the entire match, 1 for the value matched by the first '('parenthesis')' in the regular expression, 2 or more for subsequent parenthesis.  text- A string to search. typeLiteral- An optional type literal. If provided, the extracted substring is converted to this type.  Returns If regex finds a match in text- the substring matched against the indicated capture group captureGroup, optionally converted to typeLiteral. If there's no mat
