Follow the evidence.
Understand what happened.
404ensics is a digital forensics, incident response and cybersecurity resource built around investigation, practical knowledge, useful tools and the artifacts that help turn digital activity into evidence.

What is 404ensics?
A practical resource for people working with digital evidence, cybersecurity incidents and technical investigations.
404ensics exists to make useful DFIR knowledge easier to find, understand and apply.
Digital investigations rarely begin with perfect information. They begin with an alert, a compromised account, a suspicious file, an unusual connection, an encrypted system, a disk image, a memory capture or simply a question: what happened?
Answering that question requires more than a single product or technique. It requires understanding systems, knowing where artifacts exist, collecting evidence correctly, selecting the right tools and interpreting the information those tools produce.
404ensics brings those pieces together through technical articles, forensic references, curated resources, tool directories, downloads, research and practical investigative guidance.
The Mission
Practical resources built around the investigative process.
Build Understanding
Explain forensic concepts, artifacts and investigative techniques in a way that connects technical detail with practical application.
Preserve What Matters
Highlight tools and methodologies that help investigators identify, acquire and preserve potentially valuable digital evidence.
Make Sense of Artifacts
Explore the traces left behind by operating systems, applications, users and adversaries and the tools used to parse and interpret them.
Connect the Evidence
Encourage an investigative mindset: correlate multiple evidence sources, construct timelines, test hypotheses and use the available facts to reconstruct activity.
Make Useful Tools Discoverable
Curate forensic utilities, threat-intelligence resources, datasets, reference material and open-source projects that can help others perform their work.
Build Better Solutions
Support experimentation, scripting and tool development where existing forensic workflows can be improved, automated or made easier to understand.
Who is 404ensics For?
Anyone tasked with understanding what happened on a digital system or network.
The 404ensics Approach
Tools are useful. Methodology and understanding matter more.
Evidence has value only when its integrity can be trusted. Collection and preservation should always be deliberate.
Do not rely on a single artifact, alert or tool result when other evidence can independently support or challenge it.
The strongest findings often emerge when filesystem, memory, network, log and application artifacts tell the same story.
Record what was collected, what was examined, what tools were used and how conclusions were reached.
Tools provide output. Investigators determine what that output means. Always consider alternative explanations.
Operating systems, adversaries, applications and artifacts continually change. Effective investigation requires continual learning.
What You’ll Find Here
Resources designed to support investigations from first response through analysis.
DFIR Fundamentals
Practical discussion of scoping, containment, acquisition, preservation, analysis, timelines, evidence handling and incident-response methodology.
Forensic Artifacts
Information about the evidence left behind by Windows, macOS, Linux, applications, browsers, networks and other digital systems.
Downloads & Utilities
Curated tools for collecting, parsing and analyzing digital evidence, organized around the investigative task they help accomplish.
Investigator Links
Carefully selected DFIR, threat-intelligence, OSINT, ransomware, malware-analysis, vulnerability and research resources.
Technical Exploration
Testing, observations and research intended to better understand how artifacts are created and what they can reveal during an investigation.
Tools & Scripts
Development and sharing of utilities, scripts and ideas that can simplify repetitive forensic tasks or expose useful investigative information.
What 404ensics Isn’t
[ IMPORTANT CONTEXT ]
404ensics is an educational and technical resource. Content, tools and external resources should be evaluated within the context of your own investigation, organization, policies and legal authority. A tool does not replace methodology, and a technical observation does not automatically establish an investigative conclusion.
Digital evidence tells a story.
The challenge is learning how to read it.
404ensics exists to help investigators, defenders and students find the knowledge, tools and resources needed to ask better questions of digital evidence — and build defensible answers from what they find.
