Thus, a usable instance of DFIR ORC needs to embed an appropriate configuration.Ī tutorial to customize configurations, to appear shortly, under final review.Ī compilation guide to obtain a usable binary using Microsoft Visual Studio (free version) with code and configurations cited above.Īs numerous institutions and private firms, ANSSI makes use of open-source software, and wishes to contribute back to the digital security community. The main program orchestrating the collection on a machineĬonfiguration examples: configurations define which elements should be collected using embedded or external tools, and allow to cap resource usage. The release consists of three GitHub repositories, gathered in an organization. DFIR ORC is a direct result of this change in the paradigm. In an effort to face these challenges, ANSSI has revamped its investigation methodology and developed suitable tooling. In the last decade, the DFIR community has had to deal with ever-growing installed bases and to address Advanced Persistent Threats (APTs). Diagnoses arise from analysis of artefacts by forensic investigators. Strictly speaking, it cannot be used to determine whetherĪ machine has been compromised. Can DFIR ORC identify compromised machines? ¶ĭFIR ORC collects data, but does not perform any analysis. It has been used in various contexts, from the investigation of a single desktop disk to incident response for a multinational corporation. The DFIR ORC framework is the result of several years of development.

On large Microsoft Windows installed bases, administrators can deploy and gather the results as they would for any other binary. Once configured, DFIR ORC is meant to be executed easily by any computer user. Is DFIR expertise needed to run DFIR ORC? ¶ Incident responders addressing security breaches on Microsoft Windows installed bases are the primary target audience. Who can use DFIR ORC? ¶ĭFIR ORC is intended for computer security professionals wishing to collect forensically relevant data.
This helps restoring a safe production environment as quickly as possible.
When incident responders analyze machines following a security breach, they use forensic investigation techniques to understand what happened and when. Usually, analysts track traces of computer hacks or criminal activities. What is an artefact? What is digital forensics? ¶ĭigital forensics investigators study traces left by various activities on computing systems.
