SIEM and SOAR

1. Threat Hunting: Proactively Defending Against Cyber Threats Understanding, Implementing, and Impacting Organizations

2. What is Threat Hunting? Proactive search for hidden cyber threats. Goal: Detect & stop threats before damage. Example: Detecting malware like 'Snake Keylogger' used in phishing campaigns.

3. Threat Hunting in Simple Terms Analogy: Like an investigator searching for intruders beyond security cameras. Example: Hackers bypass firewalls using 'Living off the Land' techniques; hunters find hidden traces.

4. Why is Threat Hunting Important? • 70% of cyber threats bypass security. • Attackers remain undetected for months. • Essential for stopping ransomware & insider threats. • Example: Recent 'BlackCat' ransomware attacks targeting enterprises.

5. Pros & Cons ✅ Pros: Early detection, fewer false positives, better security. ❌ Cons: Requires skills, time, and continuous monitoring. • Example: Successful detection of 'Cobalt Strike' misuse before an attack.

6. Who is Affected? • Technical: SOC analysts, incident response, IT teams. • Business: Executives, risk management, legal teams. • Example: A company's CFO targeted by 'Business Email Compromise (BEC)' scams.

7. Key Steps in Threat Hunting 1. Set Objectives: What threats to detect? 2. Gather Data: Logs, network traffic, endpoint info. 3. Use Threat Intel: Leverage MITRE ATT&CK. 4. Analyze & Detect: Behavior patterns, anomalies. 5. Automate: AI & ML for efficiency. • Example: Identifying 'ProxyShell' exploits in Microsoft Exchange servers.

8. Essential Tools • SIEM: Splunk, QRadar • EDR: CrowdStrike, Defender • Threat Intel: MISP, VirusTotal • Automation: Python, Sigma rules • Example: Using Splunk queries to detect 'Maui' ransomware activity.

9. Real-World Example • Issue: Unusual login attempts on an executive account. • Discovery: Threat hunters found stolen credentials in use. • Action: Account locked, attackers blocked, security strengthened. • Example: Recent cases of 'MFA Fatigue Attacks' forcing unauthorized logins.

10. Key Takeaways • Threat hunting is proactive cybersecurity. • Requires skills, data, and AI support. • Strengthens security & business resilience. • Example: Preventing 'Log4Shell' exploits before damage.
