With this knowledge, you can improve your cybersecurity defenses and understand the complexity of network protocols. This guide is an invaluable resource for anyone looking to stay at the forefront of network security developments.



A Python script that uses the capabilities of Impacket to interact with network protocols. The main technique it can use is to extract or reset the NTLM (NT LAN Manager) information from the specified target. NTLM is a set of Microsoft security protocols designed to provide authentication, integrity, and privacy for users.



A Python script designed to execute commands on a remote machine in a Windows environment. This script probably uses the AT protocol, a legacy scheduling system, to execute commands remotely. It can interact with the Windows Task Scheduler service to schedule the execution of tasks (commands) on a remote computer.



GetST uses modern and very effective Kerberos interaction methods in AD environments. The script can be used to request service tickets for specific services in a domain. This process involves authenticating to the Kerberos Key Distribution Center (KDC) and requesting tickets that grant access to certain services.



Uses methods to interact with AD services to manage passwords. This may involve using network protocols such as LDAP (Lightweight Directory Access Protocol) or SMB (Server Message Block) to communicate with AD controllers and perform password change requests. The script can handle the authentication, encryption.



Uses techniques to analyze and interpret Kerberos tickets. Kerberos is a network authentication protocol commonly used in Windows Active Directory environments. The script probably parses the tickets to retrieve and display information such as the ticket’s encryption type, expiration date, and the identity of the primary and target servers.



Uses methods to query Active Directory for user account information. This may include retrieving details such as usernames, account settings, and other attributes stored in AD. The script can use Lightweight Directory Access Protocol (LDAP) queries or similar methods to retrieve this information from the AD database.



Uses methods of using the Kerberos protocol in Active Directory environments. Specifically, it targets accounts that do not require prior Kerberos authentication. By doing this, the script can request a Kerberos Ticket Granting Service (TGS) ticket for any user without needing their password. This ticket can then be used to attempt to crack the user’s password offline.



Uses the enumeration and service ticket query methods for accounts that have registered SPNs in the AD environment. In Kerberos, SPNs are used to uniquely identify a service instance. When a service ticket is requested for an SPN, it is encrypted with the service account password. This script is used to request tickets which can then be subjected password cracking attempts.



Uses methods to automate the process of adding a new computer account to an Active Directory domain. This may involve using LDAP (Lightweight Directory Access Protocol) or other AD protocols to contact the domain controller and create a new computer account. A script can also manage setting or changing various attributes associated with a computer account.



Methods are used to interact with the Windows Data Protection API, which is used to provide encryption and decryption capabilities to protect data such as passwords and keys. The script can perform tasks such as decrypting data protected by DPAPI, which can be crucial in forensic analysis or during a security assessment to access protected information.



Uses methods to remotely identify the architecture (32-bit or 64-bit) of the Windows operating system on the network computer. This may involve using network protocols such as SMB (Server Message Block) to interact with the remote system and gather information about its architecture. This information is essential for tailoring subsequent attacks.



Uses Kerberos methods in AD environments. The script can be used to request ticket-granting tickets that are essential for Kerberos-based authentication. This process involves authenticating to the Kerberos Key Distribution Center (KDC) and requesting a ticket that can be used to obtain service tickets for various services within the domain.




Uses methods for interacting with ESE database files, also known as JET Blue databases. These databases are used by various Windows services and programs, including Active Directory, Exchange, and Windows Update. A script can perform tasks such as reading, extracting, or manipulating data in ESE database files, which can be critical in forensic analysis.



The script uses methods to retrieve and decrypt passwords stored in Group Policy settings files. These files are often used by system administrators to configure settings on Windows machines on a network. Historically, they have been known to store credentials in encrypted form, but Microsoft released an encryption key that made it possible to decrypt these passwords.



Uses methods of interaction with Windows systems using the DCOM protocol. DCOM is a Microsoft technology for communicating between software components distributed across networked computers. A script likely uses this protocol to remotely execute commands or scripts on a target machine, using DCOM’s ability to communicate between different segments.



Uses methods to query Active Directory for user and computer account delegation options. Delegation in AD refers to the ability of one account to act on behalf of another. The script can use Lightweight Directory Access Protocol (LDAP) queries or similar methods to identify accounts with delegation permissions, which can be an important aspect when assessing the security posture of an AD environment.



GoldenPac uses modern methods related to the creation and use of the Golden Ticket. A golden ticket is a forged ticket-granting ticket (TGT) in Kerberos that can be used to gain unauthorized access to any service in an AD domain. A script can exploit vulnerabilities or misconfigurations in the AD environment to create a TGT that is trusted by a Key Distribution Center (KDC) that provides wide network access.



Techniques are used to interact with and analyze the PAC that is part of the Kerberos ticket in AD environments. The PAC contains user authorization information such as group membership and user rights. The script can use network protocols and authentication mechanisms to request and retrieve PAC data from a domain controller, which can be critical to understanding user privileges and roles in an AD domain.
