Credentialed Enumeration From Linux

Authenticated Enumeration - from Linux

1️⃣ CrackMapExec

• sudo crackmapexec smb 10.20.30.40 -u alex -p StrongPass123 --users → Enumerates domain users Displays a list of domain users along with the badPwdCount attribute.

• sudo crackmapexec smb 10.20.30.40 -u alex -p StrongPass123 --groups → Enumerates domain groups Provides a list of groups along with the number of users in each.

• sudo crackmapexec smb 10.20.30.150 -u alex -p StrongPass123 --loggedon-users → Shows currently logged-in users.

• sudo crackmapexec smb 10.20.30.40 -u alex -p StrongPass123 --shares → Lists available shared resources and access levels for the user.

• sudo crackmapexec smb 10.20.30.40 -u alex -p StrongPass123 -M spider_plus This module scans all accessible shares for readable files. You can specify a particular share using --share 'Finance Records'. The output is saved in /tmp/cme_spider_plus/<target_ip>.

2️⃣ SMBMap

• smbmap -u alex -p StrongPass123 -d CORP.LOCAL -H 10.20.30.40 → Checks accessible resources and permission levels.

• smbmap -u alex -p StrongPass123 -d CORP.LOCAL -H 10.20.30.40 -R 'Finance Records' --dir-only Displays all subdirectories within the specified directory without listing files.

3️⃣ rpcclient

rpcclient is a useful tool for interacting with Samba and MS-RPC services. It allows enumeration, modification, and deletion of Active Directory objects.

• rpcclient -U "" -N 10.20.30.40 → Establishes a null session shell with the domain controller.

• rpcclient$> queryuser 0x457 → Enumerates user by RID (0x457 in hex = 111 in decimal).

• rpcclient$> enumdomusers → Lists all domain users along with their RIDs.

4️⃣ Impacket Toolkit

Psexec.py

This tool uploads an executable to the ADMIN$ share, creates a remote service, and establishes a SYSTEM-level shell.

• psexec.py corp.local/jdoe:'SecurePass!1'@10.20.30.125 → Spawns a remote shell.

wmiexec.py

wmiexec.py leverages Windows Management Instrumentation (WMI) for command execution. Unlike psexec.py, it does not leave artifacts on the target system.

• wmiexec.py corp.local/jdoe:'SecurePass!1'@10.20.30.40 → Opens a semi-interactive shell.

5️⃣ Windapsearch

Windapsearch is a Python script for querying LDAP and extracting user, group, and computer information from an Active Directory domain.

• python3 windapsearch.py --dc-ip 10.20.30.40 -u [email protected] -p StrongPass123 --da → Retrieves members of the Domain Admins group.

• python3 windapsearch.py --dc-ip 10.20.30.40 -u [email protected] -p StrongPass123 -PU → Identifies privileged users.

6️⃣ BloodHound.py

Initially a PowerShell tool, BloodHound.py is a Python implementation useful for gathering AD-related data without needing a Windows machine.

• sudo bloodhound-python -u 'alex' -p 'StrongPass123' -ns 10.20.30.40 -d corp.local -c all → Runs BloodHound data collection.

  • -ns = Name server

  • -d = Domain

  • -c = Collection type (all data in this case)

The output consists of JSON files.

• zip -r corp_bh.zip *.json → Compresses collected data into a ZIP file.
