DFIRIST
Practical Digital Forensics, Incident Response, Detection Engineering, Threat Hunting, and AI Security.
A practitioner-led community publication for defenders — real case breakdowns, forensic technique, and detection know-how, built to help teams stop ransomware and cybercrime before it wipes out the business.
Why DFIRIST exists
Most cybersecurity content sits at one of two extremes: academic papers few practitioners have time to read, or vendor blog posts that exist to sell a product. Very little of it is written by defenders, for defenders.
DFIRIST is a community-first attempt to close that gap — breaking down real incident response cases, forensic technique, detection engineering, and emerging threats, in plain and practical language.
No hype. No fear-based headlines. Just what happened, what worked, what didn't — and what you can use on the job this week to keep ransomware and cybercriminals out of your business.
What we cover
Five categories, one standard: does it help a defender do their job better this week?
Digital Forensics
Artifact analysis, disk & memory forensics, and methodology notes for examiners.
Incident Response
Timeline reconstructions, root cause analysis, and containment lessons from real engagements.
Detection Engineering
Building and tuning detections that catch real adversary behavior, not just checkbox rules.
Threat Hunting
Hypothesis-driven hunts, TTP commentary, and active-campaign analysis for defenders.
AI Security
How AI is changing both attacker tradecraft and defender tooling — and what to watch.
Built with defenders, not just for them
DFIRIST is a community-first publication. The goal isn't just to publish articles — it's to build a space where practitioners share what they're seeing, ask questions, and help each other stay ahead of attackers.
- Weekly case file digestOne new breakdown a week, straight to your inbox.
- Practitioner discussionComment, share your own war stories, and compare notes with peers.
- Open Q&AAsk a question about a case file — answers get folded into future write-ups.
- Free, alwaysThe core content is free. Vendor support keeps it that way — see below.
Case files
Real breakdowns, built to help you take action before it's your business in the headline.
72 Hours: How a Single Phished Login Led to a Full Ransomware Shutdown
A composite case built from patterns we see across real ransomware engagements — timelines, techniques, and outcomes generalized and anonymized. It's illustrative, not a specific named incident, and it's exactly how these attacks tend to unfold.
Initial Access
An employee enters credentials into a lookalike VPN login page. No MFA is in place to stop the reuse.
Silent Escalation
Attacker moves laterally, disables backups, and harvests domain admin credentials — undetected.
Detonation
Ransomware deploys across servers and endpoints simultaneously. Finance, ERP, and production systems go dark.
Response & Recovery
IR team isolates the network, rebuilds from offline backups, and works with legal & comms on disclosure.
The pattern behind cases like this is consistent: one missing control (MFA), one late detection (backups disabled without alerting), and days of silent dwell time before encryption. Businesses that survive with minimal damage are the ones that catch it in the "silent escalation" window — which is exactly where detection engineering and threat hunting earn their keep.
