Course 30 - Practical Malware Development - Beginner Level | Episode 1: C# Offensive Operations: Recon, Persistence, and File Acquisition
In this lesson, you’ll learn about: Defensive perspectives on common red-team techniques1. System Enumeration (Detection & Hardening)
You can listen and download our episodes for free on more than 10 different platforms:

- What attackers typically try to collect:
- OS version, hostname, IP address
- Current user and privilege level
- Why it matters:
- Helps attackers tailor exploits and escalate privileges
- Defensive measures:
- Monitor unusual process behavior querying system info repeatedly
- Use Endpoint Detection & Response (EDR) to flag reconnaissance patterns
- Apply least privilege to limit accessible system details
- Common persistence targets:
- Startup folders
- Registry Run keys
- Scheduled tasks or services
- Why it matters:
- Allows threats to survive reboots and maintain access
- Defensive measures:
- Monitor changes to autorun registry keys
- Use tools like:
- Windows Event Logs
- Sysmon (for registry modification tracking)
- Enforce:
- Application allowlisting
- Regular startup audits
- Typical attacker behavior:
- Receiving commands from external servers
- Executing instructions dynamically
- Defensive measures:
- Detect unusual outbound connections (C2 patterns)
- Inspect traffic for:
- Beaconing behavior
- Irregular intervals or unknown domains
- Use network segmentation and egress filtering
- Why attackers use it:
- To deliver additional payloads or tools dynamically
- Defensive measures:
- Restrict outbound traffic to approved domains only
- Monitor:
- Unexpected file downloads
- Execution from temporary directories
- Use antivirus / EDR to scan downloaded content in real time
- These techniques (enumeration, persistence, remote control) are core attacker behaviors
- Defenders should focus on:
- Visibility (logs, monitoring, EDR)
- Restriction (least privilege, network controls)
- Detection (behavioral analytics, anomaly detection)
