Domain Password Spray
A tool written in PowerShell to perform password assessments
DomainPasswordSpray is a focused security tool designed to perform enterprise-scale password spraying assessments against Active Directory environments. It automates the process of attempting common or customized passwords against many accounts while respecting timing and throttling controls to reduce obvious lockout noise. The project includes features for credential list management, target selection (users, service accounts, or collections), and configurable rate limits so testers can tune the balance between coverage and stealth. Output formats include summary reports and structured logs to help analysts triage which accounts were hit and where to prioritize defensive follow-up. The codebase is written to be used by penetration testers, red teams, and security assessors in authorized engagements and emphasizes responsible use; the README explicitly warns against unauthorized use and stresses running tests only with permission. -

Invoke-PSImage
Encodes a PowerShell script in the pixels of a PNG file
Invoke-PSImage is a PowerShell utility that hides, extracts, and optionally executes PowerShell payloads inside image files using simple steganography techniques. It can embed a script or binary blob into an image (commonly PNG or JPEG) and later recover that payload without leaving a separate file on disk, enabling in-memory execution workflows. The tool offers options for compression and encryption so the embedded content is both smaller and protected by a passphrase when required. It includes helpers to encode a payload into an image, decode an embedded payload back to readable form, and run the extracted content directly from memory to avoid touching disk. Designed as a compact, single-file PowerShell script, it relies on .NET imaging APIs to manipulate pixel data or metadata and to store the payload in a way that survives ordinary file transfers. -

Invoke-TheHash
PowerShell Pass The Hash Utils
Invoke-TheHash is a PowerShell module providing utilities to perform “Pass-the-Hash” style remote operations over WMI and SMB by supplying NTLM hashes instead of plaintext passwords. The project includes multiple scripts/modules (Invoke-WMIExec, Invoke-SMBExec, Invoke-SMBEnum, Invoke-SMBClient, and a wrapper Invoke-TheHash) so operators can choose enumeration, file access, or command execution modes. It uses .NET’s TcpClient for direct SMB/WMI connections and performs authentication by inserting an NTLM hash into the NTLMv2 protocol flow. The module supports both local accounts and domain accounts (via domain parameter), and it accepts either LM:NTLM or pure NTLM format hashes. For command execution, it can create services on remote hosts (SMBExec style) or use WMI class methods. Since it works over network protocols rather than relying on built-in Windows clients, it can bypass some limitations or restrictions in constrained environments. -

MicroBurst
A collection of scripts for assessing Microsoft Azure security
MicroBurst is a PowerShell toolkit from NetSPI focused on assessing Microsoft Azure security by automating discovery, enumeration, and targeted auditing of cloud services and configurations. It bundles many functions to enumerate Azure resources (subscriptions, VMs, storage accounts, container registries, App Services and more), probe common misconfigurations, and harvest sensitive artifacts when available (for example storage blobs, keys, automation account credentials, and other subscription-level secrets). The project exposes both interactive helpers and scripted commands (e.g., Invoke-EnumerateAzureBlobs, Invoke-EnumerateAzureSubDomains, REST-based VM command execution and storage key retrieval routines) so operators can pivot from discovery to validated proof-of-concept actions during authorized penetration tests. -

Microsoft Defender for Cloud
Welcome to the Microsoft Defender for Cloud community repository
Microsoft Defender for Cloud (the community repository) is a centralized collection of programmatic automations, policy definitions, remediation scripts, and visualization workbooks designed to help organizations manage and operationalize Microsoft Defender for Cloud at scale. It packages ready-to-use Azure Policy definitions, Logic App templates, PowerShell automation, remediation actions, and custom workbooks so teams can deploy detections, enforce security posture, and automate responses across subscriptions and tenants. The repo includes playbooks and examples for translating recommendations into automated remediation, along with onboarding and deployment artifacts (including Terraform helpers) to simplify large-scale rollout. Content is explicitly presented as community-driven: contributors can submit Logic Apps, policies, and scripts, and the project documents contribution guidelines and CLA requirements for submissions. -

Nishang
Offensive PowerShell for red team and penetration testing
Nishang is a framework and collection of scripts and payloads which enables usage of PowerShell for offensive security, penetration testing and red teaming. Nishang is useful during all phases of penetration testing. Import all the scripts in the current PowerShell session (PowerShell v3 onwards). Use the individual scripts with dot sourcing. Note that the help is available for the function loaded after running the script and not the script itself since version 0.3.8. In all cases, the function name is same as the script name. Nishang scripts are flagged by many Anti Viruses as malicious. The scrripts on a target are meant to be used in memory which is very easy to do with PowerShell. Two basic methods to execute PowerShell scripts in memory. Use the in-memory dowload and execute: Use below command to execute a PowerShell script from a remote shell, meterpreter native shell, a web shell etc. and the function exported by it. -

PersistenceSniper
Powershell module that can be used by Blue Teams, Incident Responders
PersistenceSniper is a digitally signed PowerShell module aimed at blue teams and incident responders for automated detection of persistence mechanisms on Windows systems. It implements detection logic for techniques listed in MITRE ATT&CK (e.g. registry run keys, scheduled tasks, service modifications) and is regularly updated with new detection paths. -

PowerSharpPack
Offensive CSharp Projects wraped into Powershell for easy usage
PowerSharpPack is a consolidated offensive-security toolkit that wraps many standalone C# projects into an easy-to-use PowerShell loader. The author compiles, gzip-compresses and base64-encodes each C# binary, then dynamically loads the assemblies into the PowerShell process so operators can invoke powerful .NET tools without dropping executables on disk. The bundle exposes a single entry script (PowerSharpPack.ps1) with switches to select which embedded tool to run and an optional -Command argument to pass tool-specific parameters. Included projects cover a broad range of post-exploitation and reconnaissance needs: Kerberos tooling, host survey utilities, credential and browser data extractors, AD enumeration, privilege escalation helpers, persistence frameworks, and file/handle utilities. For convenience the repo also ships per-binary PowerShell loaders when users prefer to avoid loading the entire pack, plus helper binaries used for compression/encoding. -

TigerSafe
Free open source password manager
TigerSafe is a free open source password manager. It allows to store passwords in a file, without internet, by encrypting them with a single password. The user can then use a different password for every website he wants to use, and only has to remember a single password: the one used to encrypt/decrypt the file storing his passwords. It is highly recommended to do backups of the file storing passwords with TigerSafe, for example copy/paste it in USB flash drives, cloud drives like Google Drive, Dropbox... Indeed, users are solely responsible for their data. TigerSafe also enables you to store the 2-factor authentication mechanism mostly used by modern websites (TOTP 2FA) in a secure way. Since TigerSafe is particularly sensitive, no binary installation file is provided (because it could be infected by a virus, or have a vulnerability in its dependencies such as the JDK implementation used). Instead, installation instructions are provided, and a YouTube video for Windows. -

Ultimate AppLocker Bypass List
The most common techniques to bypass AppLocker
UltimateAppLockerByPassList is a community-curated repository that collects known techniques, patterns, and candidate binaries that have been observed or proposed to bypass Microsoft AppLocker and similar executable control policies. The project functions as a living catalog: entries list binaries, script hosts, and patterns that researchers have tested or reported in the wild, along with notes about context, platform constraints, and mitigation ideas. It is aimed primarily at defenders, incident responders, and security researchers who need a consolidated reference to understand common bypass vectors and to validate detection logic. The repository emphasizes defensive use—helping blue teams craft allow-list policies, create detection rules, and test policy hardening in isolated lab environments—rather than offensive exploitation. -

powercat
Netshell features all in version 2 powershell
PowerCat is a compact PowerShell implementation of netcat-style networking utilities that makes it easy to create TCP/UDP clients and listeners, forward ports, and move data between sockets and files. It provides both interactive shells and single-command execution modes so operators can create bind shells, reverse shells, or simple file upload/download endpoints using only PowerShell. The tool supports encrypted connections (SSL/TLS) and can act as a basic SOCKS proxy or relay, enabling flexible pivot and tunneling workflows. PowerCat is implemented as a single, portable PowerShell script that favors minimal dependencies and is convenient to drop into a target or use from an admin workstation. Because it reimplements low-level socket behavior in managed code it is especially useful in Windows environments where native tools like netcat are unavailable or restricted. -

sRDI
Shellcode implementation of Reflective DLL Injection
sRDI is a compact project that implements a shellcode form of Reflective DLL Injection, enabling DLLs to be converted into position-independent shellcode and loaded in memory by a small in-process PE loader. The codebase groups a C implementation of a reflective PE loader with multiple loader/wrapper components (native C loader, a .NET loader, Python and PowerShell conversion helpers) so authors can produce and embed sRDI blobs in different environments. The loader aims to behave like a proper PE loader: it preserves section permissions, supports TLS callbacks, performs sanity checks, and exposes flags to control behaviors such as header clearing, memory wiping, import obfuscation, and whether the shellcode receives the base address. The repository also provides utility scripts to convert DLL binaries into embedded blobs and to update static encodings used by the supplied loaders.
