zBang – Privileged Account Threat Detection Tool
zBang is a risk assessment tool for Privileged Account Threat Detection on a scanned network, organizations and red teamers can utilize zBang to identify potential attack vectors and improve the security posture of the network.
The results can be analyzed with the graphic interface or by reviewing the raw output files.
The tool is built from five different scanning modules:
- ACLight scan – discovers the most privileged accounts that must be protected, including suspicious Shadow Admins.
- Skeleton Key scan – discovers Domain Controllers that might be infected by Skeleton Key malware.
- SID History scan – discovers hidden privileges in domain accounts with secondary SID (SID History attribute).
- RiskySPNs scan – discovers risky configuration of SPNs that might lead to credential theft of Domain Admins
- Mystique scan – discovers risky Kerberos delegation configuration in the network.
Requirements to run zBang Privileged Account Threat Detection Tool
- Run it with any domain user. The scans do not require any extra privileges; the tool performs read-only LDAP queries to the DC.
- Run the tool from a domain joined machine (a Windows machine).
- PowerShell version 3 or above and .NET 4.5 (it comes by default in Windows 8/2012 and above).
zBang Privileged Account Threat Detection Tool Performance
zBang runs quickly and doesn’t need any special privileges over the network. As the only communication required is to the domain controller through legitimate read-only LDAP queries, a typical execution time of zBang on a network with around 1,000 user accounts will be seven minutes.
When you intend to scan large networks with multiple trust-connected domains, it’s recommended to check the domain trusts configuration or run zBang separately from within each domain to avoid possible permission and connectivity issues.

Memhunter – Automated Memory Resident Malware Detection
Memhunter is an Automated Memory Resident Malware Detection tool for the hunting of memory resident malware at scale, improving the threat hunter analysis process and remediation times.
It’s a self contained binary that can be deployed and managed at scale, does not use memory dumps and relies purely on memory inspection to do its work. It also does not require any complex infrastructure to deploy.
The tool was designed as a replacement of memory forensic volatility plugins such as malfind and hollowfind. The idea of not requiring memory dumps helps on performing the memory resident malware threat hunting at scale, without manual analysis, and without the complex infrastructure needed to move dumps to forensic environments.
Memhunter in a nutshell:
- It is an standalone binary that gets itself deployed as a windows service
- It uses a set of memory inspection heuristics and ETW data collection to find footprints left by common injection techniques.
- Forensic information on findings gets reported through console or event logs for forwarding
Memhunter Automated Memory Resident Malware Detection Features
The detection process is performed through a combination of endpoint data collection and memory inspection scanners. The tool is a standalone binary that, upon execution, deploys itself as a windows service. Once running as a service, memhunter starts the collection of ETW events that might indicate code injection attacks. The live stream of collected data events is feed into memory inspection scanners that use detection heuristics to down select the potential attacks. The entire detection process does not require human intervention, neither memory dumps, and it can be performed by the tool itself at scale.
- 9 hunter heuristics included (see next slide)
- 15 code injection techniques implemented on minjector test tool
- ETW data collection of suspicious events used for heuristic triggering
- Windows Event Log generation
- Exclusion of baseline detection
- Basic forensic information
- Sqlite storage integration
Memhunter Automated Memory Resident Malware Detection minjector.exe
Besides the data collection and hunting heuristics, the project has also led to the creation of a companion tool called “minjector” that contains +15 code injection techniques. The minjector tool cannot only be used to exercise memhunter detections, but also as a one-stop location to learn on well-known code injection techniques out there.

Sandcastle – AWS S3 Bucket Enumeration Tool
Sandcastle is a Python-based Amazon AWS S3 Bucket Enumeration Tool, formerly known as bucketCrawler. The script takes a target’s name as the stem argument (e.g. shopify) and iterates through a file of bucket name permutations.
Amazon S3 [Simple Storage Service] is cloud storage for the Internet. To upload your data (photos, videos, documents etc.), you first create a bucket in one of the AWS Regions. You can then upload any number of objects to the bucket.
In terms of implementation, buckets and objects are resources, and Amazon S3 provides APIs for you to manage them.
Examples of the kinds of bucket names it would look for:
- -training
- -bucket
- -dev
- -attachments
- -photos
- -elasticsearch
- […]
You can find the example bucket names file here.
Using Sandcastle – AWS S3 Bucket Enumeration Tool
Here’s how to get started:
- Clone this repo (PyPi distribution temporarily disabled).
- Run
sandcastle.pywith a target name and input file (grab an example from this repo) - Matching bucket permutations will be identified, and read permissions tested.

usage: sandcastle.py [-h] -t targetStem [-f inputFile] arguments: -h, --help show this help message and exit -t targetStem, --target targetStem Select a target stem name (e.g. 'shopify') -f inputFile, --file inputFile Select a bucket permutation file (default: bucket- names.txt) |
Status codes and testing for Sandcastle – AWS S3 Bucket Enumeration Tool
- 404 – Bucket Not Found – Not a target for analysis (hidden by default)
- 403 – Access Denied – Potential target for analysis via the CLI
- 200 – Publicly Accessible – Potential target for analysis via the CLI

Astra – API Automated Security Testing For REST
Astra is a Python-based tool for API Automated Security Testing, REST API penetration testing is complex due to continuous changes in existing APIs and newly added APIs.
Astra can be used by security engineers or developers as an integral part of their process, so they can detect and patch vulnerabilities early during development cycle. Astra can automatically detect and test login & logout (Authentication API), so it’s easy for anyone to integrate this into CI/CD pipeline.
Astra can take API collection as an input so this can also be used for testing apis in standalone mode, it looks for the following issues:
- SQL injection
- Cross site scripting
- Information Leakage
- Broken Authentication and session management
- CSRF (including Blind CSRF)
- Rate limit
- CORS misconfiguration (including CORS bypass techniques)
- JWT attack
- CRLF detection
- Blind XXE injection
