Today we had a guest lecture in our Digital Forensics class, held by a consultant from [SEC Consult](https://www.sec-consult.com/?ref=niklas-heringer.com), a cybersecurity company that offers everything from penetration testing to fully managed incident response.

They walked us through the **phases of a cyber crisis**, sharing practical insights drawn from real-world cases. It was quite interesting stuff, especially since it wasn't just theoretical knowledge but based on actual experiences.

The difference between operational and legal-grade forensics was not optimal for our course which is about the latter but it really got us into another rote.

# Active vs Passive Security

SEC Consult positions itself as both a **preventive** and **reactive** player:

- On one side: classic **penetration testing** and **security assessments**.
- On the other: **Managed Incident Response,** basically full-scale crisis handling when the red lights are already flashing.

They stressed a practical truth:

> **"In real-world incidents, you're usually doing security forensics, not courtroom-grade forensics."**

In other words: move fast, find the problem, stop the damage. Legal admissibility comes second.

# Threat Landscape: Modern Crisis Drivers

We also got an overview of how SEC sees the modern **threat landscape**. Key players and trends:

- **Hacktivists** → politically motivated attacks (e.g. defacements, DDoS)
- **FIN groups** → financially motivated, often sophisticated
- **APTs** (Advanced Persistent Threats) → state-sponsored, resource-heavy, long-term compromise strategies

They explained how the **Unified Kill Chain** provides a broader modern view compared to MITRE ATT&CK or Lockheed's original kill chain, by emphasizing:

- Entry vectors (**In**)
- Internal movement and escalation (**Through**)
- Exfiltration or impact (**Out**)

This more holistic breakdown helps defenders see attacks as **multi-phase operations** rather than isolated events.

# Tools and Techniques

We touched on tools like **Mimikatz,** simple in use, powerful in impact. It’s still effective against misconfigured or under-protected environments.

The point: attackers don’t always use zero-days. **Simple tools + bad configs = compromise**.

# Incident Response Lifecycle

SEC Consult follows a clear **incident response lifecycle**, which maps closely to standard models like NIST but with practical emphasis:

1. **Detection**
  - May come from internal logs, external notifications, or even customers
2. **Containment**
  - Segment the damage, isolate systems, avoid lateral movement
3. **Eradication**
  - Remove the cause: malware, persistence mechanisms, rogue accounts
4. **Recovery**
  - Restore clean backups, bring services back, validate integrity
5. **Lessons Learned**
  - Timeline analysis, policy review, process improvement

They pointed us to [Backdoors & Breaches](https://play.backdoorsandbreaches.com/?ref=niklas-heringer.com), a great tabletop tool for IR training that simulates attack scenarios in a card-game format. Definitely something I want to try out in my own practice.

# Final Thoughts

What stuck with me the most was the emphasis on **realism over perfection**.  
In a cyber crisis, speed and clarity beat formality. Knowing what to log, who to contact, and how to act makes all the difference.

This session gave me a better idea of how fast-moving, high-stakes incident response can feel and how good preparation is the only real defense.

Let me know if you want a printable version of this post or a companion checklist for incident response flow.  
I'll definitely be diving deeper into killchains and tabletop scenarios in the research section soon.
