EPISODE 8 — THE PROCESS THAT HID IN MEMORY Security+ Domain 4 concepts • CySA+ behavioral analytics • SOC fileless attack detection

Modern attackers don’t always drop files. Sometimes the entire attack happens in memory — invisible to antivirus, bypassing traditional scans, and relying on stealth to stay ahead of the SOC.

In this cinematic scenario, you’ll see how defenders detect fileless techniques through subtle signals: unusual PowerShell behavior, reflective loading, credential access attempts, and processes that should never run the way they’re running.

What you’ll learn:

• How fileless attacks operate without touching disk • Why memory-only processes are early indicators of compromise • How EDR/XDR telemetry exposes reflective loading & AMSI bypass attempts • How attackers attempt credential access through LSASS • What suspicious PowerShell behavior looks like • How to isolate, contain, and escalate memory-resident threats

Security Operations Skills Covered:

✔ EDR/XDR telemetry interpretation

✔ Memory analysis fundamentals

✔ Fileless malware techniques

✔ Behavioral & heuristic detection

✔ Credential theft monitoring

✔ Threat hunting signals

✔ Incident response workflow for in-memory attacks

This scenario reinforces key concepts from:

Security+ (SY0-701) — EDR/XDR, behavioral detection, malware identification, IR workflows

CySA+ (CS0-003) — Memory-based attacks, credential access attempts, advanced detection analytics

Designed to support both exam learners and working SOC analysts.

Ideal for:

— Security+ learners — CySA+ learners — SOC Tier 1 analysts — Blue team defenders — Incident responders — Anyone learning how modern attackers avoid traditional AV

Short. Cinematic. Practical. A real-world look into attacks designed to stay invisible.
