AWSGoat: A Damn Vulnerable AWS Infrastructure - Jeswin, Sanjeev

Demolabs DC Forum Page


Title:
AWSGoat : A Damn Vulnerable AWS Infrastructure

Presenter:
Jeswin Mathai, Sanjeev Mahunta

Abstract:
Compromising an organization's cloud infrastructure is like sitting on a gold mine for attackers. And sometimes, a simple misconfiguration or a vulnerability in web applications, is all an attacker needs to compromise the entire infrastructure. Since cloud is relatively new, many developers are not fully aware of the threatscape and they end up deploying a vulnerable cloud infrastructure. When it comes to web application pentesting on traditional infrastructure, deliberately vulnerable applications such as DVWA and bWAPP have helped the infosec community in understanding the popular web attack vectors. However, at this point in time, we do not have a similar framework for the cloud environment. In this talk, we will be introducing AWSGoat, a vulnerable by design infrastructure on AWS featuring the latest released OWASP Top 10 web application security risks (2021) and other misconfiguration based on services such as IAM, S3, API Gateway, Lambda, EC2, and ECS. AWSGoat mimics real-world infrastructure but with added vulnerabilities. The idea behind AWSGoat is to provide security enthusiasts and pen-testers with an easy to deploy/destroy vulnerable infrastructure where they can learn how to enumerate cloud applications, identify vulnerabilities, and chain various attacks to compromise the AWS account. The deployment scripts will be open-source and made available after the talk.

Badrats: Initial Access Made Easy - Kevin, Dominic

Demolabs DC Forum Page


Title:
Badrats: Initial Access Made Easy

Presenter:
Kevin Clark Dominic “Cryillic” Cunningham


Abstract:
Remote Access Trojans (RATs) are one of the defining tradecraft for identifying an Advanced Persistent Threat. The reason being is that APTs typically leverage custom toolkits for gaining initial access, so they do not risk burning full-featured implants. Badrats takes characteristics from APT Tactics, Techniques, and Procedures (TTPs) and implements them into a custom Command and Control (C2) tool with a focus on initial access and implant flexibility. The key goal is to emulate that modern threat actors avoid loading fully-featured implants unless required, instead opting to use a smaller staged implant. Badrats implants are written in various languages, each with a similar yet limited feature set. The implants are designed to be small for antivirus evasion and provides multiple methods of loading additional tools, such as shellcode, .NET assemblies, PowerShell, and shell commands on a compromised host. One of the most advanced TTPs that Badrats supports is peer-to-peer communications over SMB to allow implants to communicate through other compromised hosts.

Title:
Control Validation Compass – Threat Modeling Aide & Purple Team Content Repo - Scott Small
(no room for description)

Presenter:
Scott Small


Abstract:
Control Validation Compass ("Control Compass") provides a needed public resource that enables cyber security teams to actually operationalize MITRE ATT&CK for its best purpose: prioritized control validation. Control Compass unites tens of thousands of detection rules, offensive security scripts, and policy recommendations from 60+ open sources – all aligned with MITRE ATT&CK – into the largest single, continuously updated reference library for such content, wrapped in an easily searchable interface. This saves defenders, red teamers, and intel & GRC analysts serious time & effort when researching content for purple teaming efforts (aka control validation). Like its input components and sources, Control Compass resource sets are openly available to all, no strings attached. Control Compass supports a powerful second use case informed by its author’s experience advising security & intelligence teams across maturity levels: the tool also provides a library of unique, openly available threat landscape summaries organized by key adversary categories, including motivation, location, and victim industry. By enabling easy identification of relevant threat intelligence – and a simple UI-based workflow to instantly surface corresponding security controls – Control Compass greatly lowers the barrier to building accurate, intelligence-driven threat models and helps drive tighter control validation feedback loops around the threats that matter most to a given organization.

Title:
EDR detection mechanisms and bypass techniques with EDRSandBlast

Presenter:
Thomas Diot, Maxime Meignan


Abstract:
EDRSandBlast is a tool written in C that implements and industrializes known as well as original bypass techniques to make EDR evasion easier during adversary simulations. Both user-land and kernel-land EDR detection capabilities can be bypassed, using multiple unhooking techniques and a vulnerable signed driver to unregister kernel callbacks and disable the ETW Threat Intelligence provider. Since the initial release, multiple improvements have been implemented in EDRSandBlast: it is now possible to use this toolbox as a library from another attacking tool, new bypasses have been implemented, the embedded vulnerable driver is now interchangeable to increase stealthiness and the use of a pre-built offsets database is no more required! Come discover our tool and its new features, learn (or teach us!) something about EDRs and discuss about the potential improvements to this project.

Injectyll-HIDe: Pushing the Future of Hardware Implants to the Next Level - Fischer, Miller



Title:
Injectyll-HIDe: Pushing the Future of Hardware Implants to the Next Level

Presenter:
Jonathan Fischer, Jeremy Miller

Abstract:
Enterprises today are shifting away from dedicated workstations, and moving to flexible workspaces with shared hardware peripherals. This creates the ideal landscape for hardware implant attacks; however, implants have not kept up with this shift. While closed source, for-profit solutions exist and have seen some recent advances in innovation, they lack the customization to adapt to large targeted deployments. Open-source projects exist but focus more on individual workstations (dumb keyboards/terminals) relying on corporate networks for remote control. Our solution is an open source, hardware implant which adopts IoT technologies, using non-standard channels to create a remotely managed mesh network of hardware implants. Attendees will learn how to create a new breed of open-source hardware implants. Topics covered in this talk include the scaling of implants for enterprise takeover, creating and utilizing a custom C2 server, a reverse shell that survives screen lock, and more. They will also leave with a new platform from which to innovate custom implants. Live demos will be used to show these new tactics against real world infrastructure. This talk builds off of previous implant talks but will show how to leverage new techniques and technologies to push the innovation of hardware implants forward evolutionarily.

Title:
Memfini - A systemwide memory monitor interface for linux

Presenter:
Shubham Dubey, Rishal Dwivedi

Abstract:
Surprisingly, memory related events logging has been ignored by monitoring tool’s authors since a long time. There are multiple event loggers present for Linux that are capable of monitoring processes, i/o operations, function calls or whole systemwide events. But something which lacks in most is global monitoring of memory related events like allocation, attachment to a shared memory, memory allocation in foreign process etc. This has many applications in security domain or even software engineering in general. The main area of focus or use case for Memfini is to assist Security professionals for carrying out memory specific Dynamic Malware Analysis, in order to help them in finding indicators for malicious activities without reversing the behavior. Below listed are few of the use cases (which we will also be demonstrating in the talk). • Process Injection • Fileless malware execution • Shellcode Execution • Malicious shared memory usage On the other hand, it can also be helpful for Software developers, who wish to have an eagle eye on the memory allocations • Finding Memory Leaks • Error detection for debugging purposes. The is possible as Memfini is capable of monitoring memory allocations on User space, Kernel space as well as some under looked allocations like PCI device mapping, DMA allocations etc. It provides a command line interface with multiple filters, allowing a user to interact with the logs generated & get the required data. Currently, the user will be able to filter the events by individual process, type of access etc.

Abstract:
PMR (PTVA Management & Reporting) is an open-source collaboration platform that closes the gap between InfoSec Technical teams and Management in all assessment phases, from planning to reporting. Technical folks can focus on assessment methodology planning, test execution ,and engagement collaboration. Whereas management can plan engagements, track progress, assign testers, monitor remediation status, and escalate SLA breaches, this is an All-in-One fancy dashboard. The main features are: A) *Asset Management* which allows IT asset inventory tracking with system owner contacts. B) *Engagements Management & Planning* that enable security testers to follow a test execution roadmap by creating a new testing methodology or follow execution standards such as NIST, PTES or OWASP. It definitely will keep pentesting engagements and projects more professional. Also, it enables collaborative testing, gathering information and evidence uploading. C) *Report Automation* that automates boring tasks such as writing technical reports and validation reports. Generating a PDF report that is ready to share with clients and management can be accomplished with one-click. D) *All-in-One Dashboard* that will keep executives and management up-to-date with the organization's security posture. The dashboard components are: - High level of current vulnerabilities. - Engagement progress. - Remediation Status. - Track SLA breaches. -Monitoring risk exceptions.

ResidueFree - Logan Arkema
A privacy-enhancing tool to keep sensitive information off a filesystem

Title:
ResidueFree

Presenter:
Logan Arkema

Abstract:
ResidueFree is a privacy-enhancing tool that allows individuals to keep sensitive information off their device's filesystem. It takes on-device privacy protections from TAILS and "incognito" web browser modes and applies them to any app running on a user's regular operating system, effectively making the privacy protections offered by TAILS more usable and accessible while improving the on-device privacy guarantees made by web browsers and extending them to any application. While ResidueFree currently runs on Linux, its maintainers are hoping to port it to other operating systems in the near future. In addition, ResidueFree can help forensic analysts and application security engineers isolate filesystem changes made by a specific application. The same implementation ResidueFree uses to ensure that any file changes an application makes are not stored to disk can also be used to isolate those changes to a separate folder without impacting the original files.

Biography:
Logan is a former student-turned-independent researcher and software developer. While he makes a living conducting IT, security, and privacy audits, his most impactful hacking is 1337ing his job's policies as a union rep to elevate workplace privileges. He has an OSCP, other certs from days wooing federal hiring screeners to pass along his application, and The Time Warp stuck in his head from the time he heard "rm -rf" could be pronounced "rimm raff."

Title:
SharpSCCM

Presenter:
Chris Thompson, Duane Michael

Abstract:
SharpSCCM is a post-exploitation tool designed to leverage Microsoft Endpoint Configuration Manager (a.k.a. ConfigMgr, formerly SCCM) for lateral movement from a C2 agent without requiring access to the SCCM administration console. SharpSCCM supports lateral movement functions ported from PowerSCCM and contains additional functionality to abuse newly discovered attack primitives for coercing NTLM authentication from local administrator and SCCM site server machine accounts in environments where automatic client push installation is enabled. SharpSCCM can also dump information about the SCCM environment from a client, including domain credentials for Network Access Accounts. Further, with access to an SCCM administrator account, operators of SharpSCCM can execute code as SYSTEM or coerce NTLM authentication from the currently logged-in user or the machine account on any SCCM client.

TheAllCommander - Matthew Handy
An open-source tool as a framework to prototype and model malware comms.

Title:
TheAllCommander

Presenter:
Matthew Handy

Abstract:
TheAllCommander is an open-source tool which offers red teams and blue teams a framework to rapidly prototype and model malware communications, as well as associated client-side indicators of compromise. The framework provides a structured, documented, and object-oriented API for both the client and server, allowing anyone to quickly implement a novel communications protocol between a simulated malware daemon and its command and control server. For Blue Teamers, this allows rapid modeling of emerging threats and comprehensive testing in a controlled manner to develop reliable detection models. For Red Teamers, this framework allows rapid iteration and development of new protocols and communications schemes with an easy to use Python interface. The framework has many tools or techniques used by red teams built in, such as a SOCKS5 proxy, which then use the implemented communication scheme. This allows comprehensive testing of the detection and functional capability of the communication scheme, allowing for efficient design and development choices to be made before committing to production tool development. To facilitate this goal, TheAllCommander includes a Java based command and control server with a simple API to allow new plug-ins for server-side control. There is a python-based emulation client, which can be easily extended using the API to allow new client side communications code. Several reference implementations for covert malware communication are provided to allow out-of-the-box modeling, including emulated client browser HTTPS traffic, DNS queries, and email traffic. The tool chain includes support for several common Red Team tactics, such as Remote Desktop tunneling and FODHelper UAC bypass. This implementation effectively generates both client side and network traffic indicators of compromise.

A visualization construct for memory analysis.

Title:
Xavier Memory Analysis Framework

Presenter:
Solomon Sonya

Abstract:
Malware continues to advance in sophistication. Well-engineered malware can obfuscate itself from the user and the OS. Volatile memory is the unique structure malware cannot evade. I have engineered a new construct for memory analysis and a new open-source tool that automates memory analysis, correlation, and user-interaction to increase investigation accuracy, reduce analysis time and workload, and better detect malware presence from memory. This talk demos a new visualization construct that creates the ability to interact with memory analysis artifacts. Additionally, this talk demos new, very impactful data XREF and a system manifest analysis features. Data XREF provides an index and memory context detailing how your search data is coupled with processes, modules, and events captured in memory. The System Manifest distills the analysis data to create a new memory analysis snapshot and precise identification of malicious artifacts detectable from malware execution especially useful for exploit dev and malware analysis!

Title:
Zuthaka: A Command & Controls (C2s) integration framework

Presenter:
Lucas Bonastre, Alberto Herrera

Abstract:
The current C2s ecosystem has rapidly grown in order to adapt to modern red team operations and diverse needs (further information on C2 selection can be found here). This comes with a lot of overhead work for Offensive Security professionals everywhere. Creating a C2 is already a demanding task, and most C2s available lack an intuitive and easy to use web interface. Most Red Teams must independently administer and understand each C2 in their infrastructure. Zuthaka presents a simplified API for fast and clear integration of C2s and provides a centralized management for multiple C2 instances through a unified interface for Red Team operations. A collaborative free open-source Command & Control development framework that allows developers to concentrate on the core function and goal of their C2. Zuthaka is more than just a collection of C2s, it is also a solid foundation that can be built upon and easily customized to meet the needs of the exercise that needs to be accomplished. This integration framework for C2 allows developers to concentrate on a unique target environment and not have to reinvent the wheel. After we first presented Zuthakas' MVP at Black hat USA 2021 and DEFCON demo labs, we are now presenting the first release with updated post-exploitation modules to support text based modules, as well as file based ones. With a lab populated of commonly used C2s and its out-of-the-box integrations.
