Red Team Reality Check — Understanding the Radar Rather Than Evading It
I still remember my first labs.
Back then, a classic payload was often enough to get a shell and move through the environment comfortably.
Today? It's a different story.
And honestly… it's impressive to see how much Blue Teams have progressed in recent years.
👁️ What Modern EDRs See
- 💉Memory injections — process hollowing, reflective DLL loading
- 🔴Suspicious behaviours — unusual action sequences
- 📡Abnormal API calls — NTDLL hooks, syscall patterns
- ↔️Lateral movement — WMI, PsExec, SMB lateral
- ⚡Unusual PowerShell execution — AMSI, Script Block Logging
🏭 The Reality on Enterprise Grounds
Classic signatures
Detected within seconds — copy-pasted payloads do not last long anymore.
Files vs behaviours
SOCs monitor behaviours far more than the files themselves.
Public tooling
Mimikatz, CobaltStrike, Metasploit in default config — detected immediately.
Moving fast
Speed generates noise. Noise generates alerts. Alerts generate a response.
💡 The Real Objective of a Red Team Exercise
It is not just about evading the EDR
The goal of a Red Team exercise is not to infiltrate without being seen at all costs. The real objective is:
« The most interesting lessons often come from the alerts that did fire. »
- →Understand what the SOC sees — which telemetry, which rules
- →Identify blind spots — what is not surfacing yet
- →Test real detection and response capabilities
- →Help improve the overall defensive posture
📚 Real Case — Heavily Monitored Environment
What triggered alerts vs what went unnoticed
Detected in seconds
Noisy techniques — classic injections, known tooling
Went unnoticed
Lower-noise techniques — not "magic", just quieter
What the SIEM saw
Behavioural correlations, not just file hashes
Key lesson
Observing what triggers an alert is as valuable as the exploit itself
🔗1. Correlation
👉 An isolated event is not an alert. It is the chain that matters.
- Multi-source correlation: endpoint + network + identity
- Detection of attack sequences, not isolated actions
- SIEM rules based on complete kill chains
🧠2. Behaviour
👉 UEBA — User and Entity Behavior Analytics.
- Behavioural baselines per user and per machine
- Statistical deviations — what falls outside historical norms
- Anomaly detection without known signatures
🔬3. Endpoint Visibility
👉 EDR — granular telemetry on every workstation and server.
- Full process trees with command-line arguments
- Memory scanning — shellcode, reflective injection
- Network connections per process — who talks to whom
🎯4. Threat Hunting
👉 Proactively hunting what the rules have not found yet.
- MITRE ATT&CK-based hypotheses — hunting TTPs
- Manual investigation in raw telemetry
- Discovering blind spots before attackers exploit them
📋 Advice If You Work in Red Team
What separates a beginner from an experienced operator
- 1Spend time understanding logs — Windows Event Log, Sysmon, ETW
- 2Study how EDRs actually work — hooks, kernel callbacks, telemetry pipelines
- 3Learn Windows/Linux telemetry — what surfaces, what does not
- 4Build realistic labs — with EDR enabled, SIEM connected, and a Blue Team (even yourself)
🧠 What This Taught Me
Modern Red Teaming is no longer just about "staying under the radar".
It is about understanding how the radar works.
Watching a Blue Team respond effectively in real time… is often just as satisfying as a successful exploit.
Because ultimately, the objective is shared:
✔ Strengthen the organisation's resilience
✔ Find blind spots before real attackers do
✔ Raise the level of both teams simultaneously
What detection has already surprised you during a Red Team exercise or pentest? A behaviour you thought was quiet, an unexpected correlation, a more aggressive EDR than expected?
