Respond with Digital Forensics & Incident Response (DFIR) effectively to malware infection, hacker attack, fraud, data theft and other criminal or unwanted digital activities with the support of our highly skilled first responders and certified DFIR experts.

Professional Digital Forensics & Incident Response (DFIR)

Our specialized first responder team provides competent and dedicated support so you can respond fast to cyber security incidents. Our incident response service gives you direct access (upon request 24 h x 365 days) to our pool of experts and includes an initial workshop to ensure seamless collaboration.

To prepare for cyber security incidents, we offer incident response/digital forensic readiness assessments and incident response exercises (IREX) & trainings. Our DFIR experts support you in developing or optimizing your individual incident response process including use cases and the corresponding IR playbooks.

If your focus is on a comprehensive investigation of a cyber security incident, our DFIR team comes into play to examine data on digital devices like computers, mobile phones, memory sticks, etc. and to find answers to the questions: who did what, when, where and why (how).

Examples of incidents which may trigger IT forensic investigations are: Malware infection, hacker attacks, data theft, data leakage, fraud, mobbing, intentional deletion of data, possession and provision of digital media with illegal content, etc.

The digital forensic investigation needs to be carried out thoughtfully to avoid that potential legal evidence is irreversibly destroyed or will be rejected in court. IT forensic analyses may be very complex and depend on expert know-how, as well as specialized soft- and hardware, in order to be able to meet legal requirements. Thus, Oneconsult has highly qualified and certified DFIR experts and a well-equipped digital forensics lab.

Are you planning to implement a Security Operations Center (SOC) or would you like to optimize the performance of your current solution? Our DFIR consultants will support you in requirements analysis, design, evaluation, tendering and implementation.

Malware Incident Response

If business-relevant systems have been infected with malware (for example by a computer virus or a ransomware trojan like CryptoLocker) a fast and effective reaction is critical to take control of the incident. Our professional malware incident response team helps you to:

  • Identify and isolate infected systems
  • Determine the root cause / gateway of the infection
  • Develop short-term measures to control the malware infection quickly and effectively
  • Analyze the malware to better understand its behavior and capabilities
  • Create an action plan to remove the malware, to avoid and be better prepared for future malware infections

A malware incident response project is usually made up of the following steps:

  • Briefing / preparation
  • Initial live analysis of the infected infrastructure
  • Proposal of short-term measures to master the infection
  • Data acquisition with forensic methods and tools
  • Analysis of the malware and infected systems with specialized tools and techniques
  • Documentation incl. action plan to remove the malware
  • Presentation / discussion (optional)

Our customers benefit from a very short reaction time, pragmatic approach and our vast IT security knowhow (malware analysis, APT tests, incident response, client audits, reverse engineering, etc.).

Digital Forensic Investigation

Once an incident has happened that requires digital forensic investigation, a fast and effective reaction is of paramount importance.

Our IT forensic investigation services cover the following specializations:

  • Computer forensics: Servers, clients (PCs and notebooks), peripheral devices
  • Network forensics: Network components (routers, switches, firewalls, etc.)
  • Mobile forensics: Smartphones, tablets, PDAs, cell phones

All digital forensic projects are conducted according to the following systematic process:

  • Briefing / preparation
  • Pick-up of devices (if applicable)
  • Forensic data acquisition
  • Data analysis
  • Documentation
  • Return of devices (if applicable)
  • Presentation / discussion

We will provide detailed, reproducible forensic analysis and documentation which can be used in court and ensures absolute data integrity and a complete documentation.

IT Forensics Readiness / Incident Response Readiness

IT forensic readiness (also known as digital forensic readiness) makes sure you are prepared for a digital forensic related incident by guidelines, procedures and further organizational and technical measures.

A digital forensics guideline describes the processes, roles and responsibilities, tools and measures to be prepared in case a digital investigation is required.

Usually the following steps are involved to develop a customized digital forensic readiness concept:

  • Initial workshop: Definition of scope and requirements
  • Document grinding and interviews
  • Workshop: Definition of processes, roles and responsibilities, tools and measures (technical and conceptual)
  • Write-up of draft digital forensics guideline
  • Review of draft
  • Finalization

Based on the digital forensics guideline, the following measures may have to be implemented:

  • Tool selection
  • Role-based forensic training of staff
  • Set-up of digital forensics organization
  • Implementation of required logging systems and functions
  • Service agreements with third parties
Approach: Digital Forensics & Incident Response (DFIR)

Each of our DFIR projects starts with a kick-off meeting (briefing) to make sure we understand your specific requirements and expectations, agree on basic conditions and clarify open points.
