Create by @pxcs. This tool targeted to get information about the versions of software and services running on the network. This information can be used to identify known vulnerabilities and exploits specific to those versions. Mainly used for enumerate user accounts, group memberships, and roles within a target system. Knowing user privileges and access rights can help Attackers to identify potential targets for privilege escalation.

Ghost Hunter | Brazilian Karambit | Enumeration Tool

Ghost Hunter | Enumeration Tool:
These tools can help to uncover network policies, firewall rules, and routing tables. Understanding these configurations can help Attackers find ways to bypass security measures. Simple Network Management Protocol (SNMP) enumeration can reveal detailed device information, including system configurations, hardware details, and running processes, which can be leveraged for further attacks.

Warning

The application is included in the standard of Enumeration tool package was not available yet.
You can also download the release and unzip/untar, only after the test was completed on active directory scenario.

Warning

The application is not compatible yet with the official HarpoonHound project. Also, it has not been tested on any other Enumeration tool.

Role for Kerberos attack

A senior penetration tester or advanced cyber criminal focusing on network enumeration and Kerberos attacks, having a comprehensive set of tools and features is crucial.

Key Features and Strengths

Kerberos Interaction

Automated AS-REQ and TGS-REQ, for automates the sending of AS-REQ (Authentication Service Requests) and TGS-REQ (Ticket Granting Service Requests) messages to the Kerberos Key Distribution Center (KDC). This streamlines the process of obtaining TGTs and service tickets.

Capability

Extraction and Parsing: It includes functionality to parse and extract relevant information from the tickets received, which is essential for further analysis or attacks. The tool can request service tickets for various service accounts, which can then be extracted for offline password cracking. This is a critical component of the Kerberoasting attack.

YARA for Enumeration and Kerberoasting Protocol

The tool primarily used in malware research and detection. However, it can be adapted for various purposes in cyber-attacks, including the detection of specific behaviors such as enumeration and Kerberoasting in a network. Kerberoasting is an attack method that targets the Kerberos authentication protocol used in Windows environments to extract hashed credentials for brute-force cracking. And for Detection enumeration activities often involve scanning for open ports, user accounts, and services. Detecting such activities can involve looking for specific strings or patterns associated with known enumeration tools or behaviors.

YARA to detect Kerberoasting activity:

rule KerberoastingDetection
{
    meta:
        description = "Detects Kerberoasting tools and activities"
        author = "Username"
        date = "2020-07-02"
        reference = "https://github.com/pxcs/KerberossianCracker"

    strings:
        $rubeus = "Rubeus"
        $JtR = "John-the-Ripper"
        $hashcat = "hashcat"
        $tgsrepcrack = "tgsrepcrack"
        $gettgssession = "Get-TGSSession"
        $invoke_kerberoast = "Invoke-Kerberoast"
        $request_spn = "Request-SPN"
        $spnrequest = "spnrequest"
        $kerberoast = "kerberoast"

    condition:
        any of ($rubeus, $Jtr, $hashcat, $tgsrepcrack, $gettgssession, $invoke_kerberoast, $request_spn, $spnrequest, $kerberoast)
}

Run YARA protocol:

yara -r /path/to/rules /path/to/scan
