Infrastructure Penetration Testing
Network, Infrastructure & Cloud
Whether you are a digital asset provider with some Azure cloud infrastructure, or an international telecoms organisation with hundreds of thousands of public IPs, we can thoroughly assess your network infrastructure (on-prem or cloud) with expert level attack coverage.
-
Scope
Atlan Digital works with you to develop a detailed scope of the penetration testing to be undertaken.
-
Recon
In the first phase Atlan Digital will perform OSINT, analysing the routing mechanisms, and then all your systems will then be scanned for all active TCP and UDP ports and we will establish the security rule-base.
-
Exploit
In the exploitation phase Atlan Digital will iteratively identify and exploit vulnerable systems using public vulnerability information, and configuration & design errors. A scenario analysis over the entire network will is conducted.
-
Report
In the final phase Atlan Digital will perform comprehensive reporting of the issues identified. The risks will be rated according to numeric CVSS scores alongside an internal qualitative risk grading.
Web Application Penetration Testing
360° Coverage on Web Application Pen Tests
Enterpise applications, e-commerce platforms, trading systems, SasS platforms and other web first components dominate the corporate landscape. We work to comprehensively assess their security posture for known and unknown security vulnerabilities.
Methodology
Our methodology is built upon the PTES (Penetration Testing Execution Standard) and the OWASP TOP 10 Framework but also informed by our teams experience of conducting 100s of application tests.
Fingerprinting
Mapping web app, hosts, content scripts and files by looking at the supporting infrastructure Source code analysis, developer commands, client side validation, applet and class decomplication.
Platform Enumeration
Exploit known OS and application vulnerabilities Attempt to use default insecure configurations.
Application Functionality
Circumvent application normal processing by conducting parameter poisoning, directory traversal and XXE HTML form modification, SQL command insertions, unauthorized database access, database corruptions.
Authentication
Cookie examination, session re-use, sensitive cached information Intrusive account testing is performed at the end including brute forcing user accounts and password attacks.
Reporting
Comprehensive reporting risk rated by both CVSS3 and Atlan.
Mobile Penetration Testing
Mobile Application – Android & iOS
As an extension of web applications, mobile applications can allow extended funcionality - whether as a transcation signing mechanism, custom 2 factor authentication solutions, thick clients providing business critical functions - we inspect these applications at the deepest levels.
OWASP Top 10 – Mobile
While specific techniques exist for individual platforms, a general mobile threat model is used by Atlan Digital in creating a mobile security testing methodology for any platform. The outline below describes this general mobile application testing methodology.
Prerequisites/Planning
Tasks and requirements before conducting the mobile security assessment.
Information Gathering
The steps and things to consider when you are in the early stage reconnaissance and mapping phases of testing as well as determining the application’s magnitude of effort and scoping.
Static Analysis
Analyzing raw mobile source code, decompiled or disassembled code.
Dynamic Analysis
Executing an application either on the device itself or within a simulator/emulator and interacting with the remote services with which the application communicates. This includes assessing the application’s local inter-process communication surface, forensic analysis of the local filesystem, and assessing remote service dependencies.
ICS Penetration Testing
Industrial Control Systems (SCADA)
Critical infrastucture provides much of the backbone of a city's, or even a country's successful operational ability. In troubling times, these systems can be high priority targets for nation states, or advanced cyber criminal groups. We can apply our methodologies to help identify weak points and security risks to allow you to mitigate them.
-

- Review findings with key stakeholders
Secure Code Review
JavaScript, Ruby, Infra as code, NodeJS, Python, .NET, C/C++
Finding security vulnerabilites before applications reach deployment stage is critical. We can work with your developers collaboratively to bake in security or even help you develop a Secure Development Lifecycle (SDLC).
Secure Code Review:
Reviews are performed in alignment with industry proven best practices, guidelines and standards from organisations such as OWASP, MITRE, CERT and NIST. A general threat model is used by Atlan Digital when conducting source code reviews for complex enterprise applications.
Prerequisites/Planning
Evaluating tasks and requirements for conducting the code review, as well as assessing the application’s magnitude and scope of effort required.
Static Analysis
Analysing raw source code, using manual techniques and automated scanners that highlight code hotspots.
Developer & Architect Interviews
We will work closely with the developers where appropriate to expediate the process of understanding the code, understanding the architecture of the application and providing knowledge transfer.
Information Gathering
Review of all the application’s supporting documentation and development guidelines. This allows consultants to identify the intended purpose, functionality and development approach.
Dynamic Analysis
Working in combination with static analysis using human and automated resources; we will also perform dynamic analysis of the code, in the event the code is unreachable statically or where efficiency is improved dynamically.
Software Development
Custom Software, Machine Learning & Tooling
With many of our consultants having contributed to the security community, or having been full time developers themselves, we can respond to requests to develop programmatic solutions where cyber security domain knowledge is essential.
Example Capability - SharpML:
SharpML employes C# to mine Active Directory file shares, while bundling a resource file. This resource file is a custom Machine Learning algorithm written in Python (compiled with Pyinstaller) whose logic uses Clustering and Classification to evaluate the likelihood of a User / Password pair combinations and subsequently automictically test these against a Domain Controller to assist operators in identifying passwords littered on fileshares.
A version of this tool had been open sourced by the consultants when at Hunnic Cyber but Version 2, wherein further developments have been made internally by Atlan Digital can be requested. The write up for this project can be viewed here. Our current research outline around building a Generative Adversarial Network for Malware Development can be viewed viewed here.
Penetration Testing
We can develop solutions to complement our manual testing activities to enable a client to be tested 24/7, 365 days of the year.
Red Team & Malware Development
We can assist clients or other consultancies in developing tooling to enhance security testing activities.
Machine Learning & Automation
As part of our consulting efforts we can develop solutions to help automate security tasks, continuous security scanning tools or apply machine learning to security problem solving.
