Investigate real evidence, and build the DFIR skills to show for it.

Every case hands you real artifacts to examine, from disk and memory images to network captures, mobile and cloud evidence and live EDR and SIEM feeds. They come in the formats you meet on the job and open in the tools analysts actually use, like Autopsy, Volatility and Wireshark. The cases run from a single-artifact first look to a multi-hour intrusion, so they suit a working professional sharpening their skills and someone still learning the craft.

The Red Herrings case library: dozens of cases across digital forensics and incident response, filterable by discipline, difficulty and certification path.
A library that teaches: dozens of cases across two disciplines
Evidence in real formatsDisk, memory, PCAP, cloud and mobile, opened in Autopsy, Volatility and Wireshark
Unlimited unique variationsEvery run reseeds the names, times, hashes and IPs, so each evidence set is different and a copied answer is wrong
Cert-aligned pathwaysTracks mapped to GCFE, GCFA, GNFA, GCFR and MITRE ATT&CK

The First Look cases are free, no account and no watermark. Download for Windows, macOS or Linux and work a real case end to end, fully offline. When you're ready for a class, a 30-day trial adds sample cases from the paid library, the student portal, timed exams and whole-class grading.

What makes it different

A unique case for everyoneNames, timestamps, hashes and IP addresses are all generated from a seed, so everyone works different evidence and a copied answer is the wrong one.
Evidence in real formatsYou work from disk and memory images, packet captures, Windows event logs, registry hives, Prefetch, browser, email and mobile databases, along with cloud, EDR and SIEM feeds.
The tools of the jobYou work the evidence in the software real analysts use, like Autopsy, Volatility, Wireshark and Eric Zimmerman's EZ Tools, rather than in a proprietary sandbox.
Pathways to the certsFollow a track from First Look to a capstone, aligned to GCFE, GCFA, GNFA, GCFR, EnCE and Cellebrite and mapped to MITRE ATT&CK.
Runs fully air-gappedEverything is generated on your own machine, with no account, cloud or network, so it's safe to run in an isolated classroom or a secure facility.
Answers you can trustNo answer is ever hard-coded. Each one is re-derived from the generated evidence and confirmed by an independent parser before release, a step we call the verification check.

Built for everyone who trains on real evidence

The same engine serves a first-year class and a corporate SOC. Pick the path that fits.

A cyber range gives everyone one shared lab. This gives each person their own.

Building realistic evidence by hand takes a senior specialist days per case, and a cyber range rents you one shared lab in its cloud. Red Herrings generates a different case for everyone, runs on your own machine, and grades it for you.

Every other cyber range
  • One shared environment, the same for everyone
  • Hosted in the vendor's cloud, so you rent seats by the month
  • Answers and write-ups circulate within a term
  • Priced per student because the vendor pays for the compute
  • Needs the internet; nothing works in an air-gapped room
Red Herrings
  • A different case for every learner, generated fresh
  • Runs on the learner's own laptop, nothing to host
  • Collusion fails by design: a classmate's answer is the wrong answer
  • One flat price, well under per-seat range pricing
  • Works fully offline, even in an air-gapped classroom

One authored case becomes a hundred unique, auto-graded labs, and every extra person costs nothing to add. No other training tool can say the same.

Real evidence, and an answer key checked against it

These aren't multiple-choice quizzes dressed up as forensics. The artifacts come in the real formats of the job, and the answer key is checked against them before anyone sees it.

01

Real evidence, in the formats they'll meet on the job

  • Digital forensics: disk images, registry hives, Windows event logs, Windows and Linux memory images, PCAPs, Prefetch, LNK and jump lists, browser history, email, cloud audit logs and mobile databases, all in genuine on-disk formats.
  • Incident response: EDR detection feeds, SIEM alert exports, packet captures and host event logs, mapped to MITRE ATT&CK and tagged with the NIST 800-61 phases, so students respond the way a responder does.
  • Opens in the tools of the trade: Autopsy, FTK Imager, Registry Explorer, EvtxECmd, Wireshark, Volatility 3 and standard SQLite and email tools.
02

A different investigation for everyone

  • Names, timestamps, hashes, IPs and answers all change from one seed, so a copied answer is the wrong answer.
  • Catch collusion, not only cheating: a per-question report flags which submissions look most alike.
03

The key is checked against the files

  • Every answer is computed from the generated evidence, never hard-coded, then confirmed present in each file by an independent parser before release. This is the verification check.
04

Grading that shows its work

  • Auto-grading with sensible tolerances: hashes ignore case, timestamps allow a few seconds, free text is fuzzy-matched and flagged for review. Every score shows why, and one click overrides it.
  • Grade the whole class at once, see per-question correct rates, and export to Canvas, Blackboard, Moodle or D2L, or post over LTI 1.3.
  • Students can solve in the browser: a private link per student, practice or timed exam, with the answer key never reaching the page.
05

Built for how forensics is actually taught

  • A learning on-ramp: guided mode walks a stuck learner from where to look, to how to work it, to the answer, one question at a time. Or run any case as a capture-the-flag.
  • Investigation report and chain of custody: a court-ready template with the evidence manifest and hashes already filled in, which is the part employers hire for and most courses skip.
  • Certification-prep and ATT&CK tracks: filter forensics cases by cert path (GCFE, GCFA, GNFA, GCFR, EnCE, Cellebrite, Magnet) and incident-response cases by MITRE ATT&CK tactic, or follow a learning pathway from first look to capstone.

Frequently asked questions

Does it phone home or upload student data?

No. Generation and grading run entirely on your machine with no network call. The software contacts a server only to activate, refresh or deactivate a license, when it sends only the license key, a derived machine id, the hostname and the app version, and to check GitHub for a new version if you turn that on. Air-gapped labs activate offline.

How do I know the answer key is correct?

After generating each lab, Red Herrings re-opens every artifact with an independent parser (The Sleuth Kit, python-registry, python-evtx, LnkParse3, dpkt and others) and confirms each answer is present in the evidence. The result is the green Verified checklist. Answers are computed from the generated evidence, never hard-coded.

Which forensic tools do the artifacts work with?

The evidence is written in real on-disk formats, so it opens in Autopsy, FTK Imager, Registry Explorer, EvtxECmd, PECmd, JLECmd, Wireshark, Volatility 3, and standard SQLite and email tools.

Can I get grades into Canvas, Blackboard, Moodle or D2L?

Yes. Grade the whole class in Red Herrings, then export a grade file in Canvas, Blackboard, Moodle or D2L Brightspace format, with an optional per-student feedback note listing what each learner missed. You can also export a case as a Common Cartridge (.imscc) content module that imports into any conformant LMS.

Is there anything to help beginners learn?

Yes. Guided mode on the Solution screen steps a learner from a nudge about where to look, to how to work the question with the right tool, to the answer, one question at a time, instead of showing everything at once. An optional guided worksheet prints a short hint under each question and a tool quick-start appendix, so students can start away from the app.

Does it cover incident response, or only forensics?

Both. Digital forensics cases cover disk, registry, event logs, memory, network, mobile and cloud evidence. Incident response cases are worked from EDR detection feeds and SIEM exports, mapped to MITRE ATT&CK and tagged with the NIST 800-61 phases. Every plan includes both.

Do students need to install anything?

No. Hand each student a zip to work in their own tools, or a private link to the student portal, where they read the evidence and answer in the browser. Grading runs on your machine either way.

Can I write my own scenarios?

Yes. The visual editor validates live and previews a resolved answer key, so you see exactly what a student will get. Export a pack to share or sell it.

Can I remove the Red Herrings branding?

Yes, with a white-label license. One setting rebrands every screen and document with your institution or company identity.
