Introduction
Cyber Threat Intelligence (CTI) is a critical component of modern cybersecurity, enabling organizations to proactively identify and mitigate threats. Red Teams leverage CTI to simulate adversary tactics, test defenses, and improve incident response. This article explores key techniques, commands, and tools used by professionals like CrowdStrike’s Red Team Engineers.
Learning Objectives
- Understand core Red Team tactics and CTI applications.
- Master essential Linux/Windows commands for threat hunting.
- Learn how to analyze and mitigate advanced cyber threats.
1. Network Reconnaissance with Nmap
Command:
nmap -sV -A -T4 <target_IP>
What It Does:
Performs an aggressive scan (-A) with version detection (-sV) and fast timing (-T4) to identify open ports, services, and OS details.
Step-by-Step Guide:
1. Install Nmap:
sudo apt install nmap Linux
2. Run the scan against a target IP or subnet.
3. Analyze results for vulnerabilities (e.g., outdated services).
2. Exploiting Vulnerabilities with Metasploit
Command:
msfconsole use exploit/windows/smb/ms17_010_eternalblue set RHOSTS <target_IP> exploit
What It Does:
Leverages the EternalBlue exploit (CVE-2017-0144) to compromise unpatched Windows systems.
Step-by-Step Guide:
1. Launch Metasploit:
msfconsole
2. Search for exploits:
search eternalblue
3. Configure and execute the exploit.
3. Detecting Malicious Activity with Sysmon
Windows Command (Config):
<Sysmon schemaversion="4.90"> <EventFiltering> <ProcessCreate onmatch="exclude"/> <FileCreateTime onmatch="include" /> </EventFiltering> </Sysmon>
What It Does:
Sysmon logs process creation and file changes for threat detection.
Step-by-Step Guide:
1. Download Sysmon from Microsoft.
- Apply a custom config to monitor suspicious activity.
- Use SIEM tools (e.g., Splunk) to analyze logs.
4. Cloud Hardening in AWS
AWS CLI Command:
aws iam create-policy --policy-name "LeastPrivilege" --policy-document file://policy.json
What It Does:
Enforces least privilege by restricting IAM permissions.
Step-by-Step Guide:
1. Define a minimal policy in `policy.json`.
2. Apply it to users/roles.
3. Audit permissions with:
aws iam get-account-authorization-details
5. API Security Testing with OWASP ZAP
Command:
docker run -t owasp/zap2docker zap-api-scan.py -t https://api.example.com -f openapi
What It Does:
Automates API vulnerability scanning (e.g., SQLi, XSS).
Step-by-Step Guide:
1. Pull the OWASP ZAP Docker image.
2. Scan an API endpoint for flaws.
3. Review the report for critical findings.
6. Threat Intelligence Feeds with MISP
Command:
misp-import --url <MISP_instance> --event <event_ID>
What It Does:
Imports threat indicators (IPs, hashes) for analysis.
Step-by-Step Guide:
1. Set up a MISP instance.
2. Fetch threat data from trusted sources.
3. Correlate IOCs with internal logs.
7. Memory Forensics with Volatility
Command:
volatility -f memory.dump --profile=Win10x64 pslist
What It Does:
Extracts running processes from a memory dump.
Step-by-Step Guide:
1. Install Volatility:
pip install volatility3
2. Analyze a memory image for malware artifacts.
What Undercode Say
- Key Takeaway 1: Red Teams must continuously update tactics to match real-world adversaries.
- Key Takeaway 2: Automation (e.g., ZAP, MISP) is critical for scalable threat detection.
Analysis:
The rise of AI-driven attacks demands adaptive defenses. CrowdStrike’s approach highlights the need for proactive threat hunting, cloud security, and memory forensics. Future threats will likely exploit IoT and AI APIs, requiring advanced CTI integration.
Prediction:
By 2026, AI-powered threat actors will automate zero-day exploits, forcing defenders to adopt AI-augmented Red Teaming and real-time intelligence sharing.
