2023 Threat Hunting Report: Crowdstrike
Executive Summary
As we continue to navigate the ever-evolving cyber threat landscape, threat hunting has become a vital component of any organization’s cybersecurity strategy. In this report, we will dive into the latest threat hunting trends, tactics, and techniques used by attackers, and provide insights on how to stay ahead of the curve.
Introduction
Threat hunting is the continuous process of identifying and mitigating unknown threats within an organization’s systems and networks. It involves using threat intelligence, behavioral analytics, and human expertise to detect and respond to sophisticated attacks. In this report, we will explore the findings of Crowdstrike’s 2023 threat hunting report, which examines the latest trends and techniques used by attackers.
Key Findings
- Rise of Double Extortion Ransomware
Double extortion ransomware attacks, where attackers steal sensitive data in addition to encrypting it, have become increasingly popular in 2023. This approach allows attackers to extort victims twice, making it a lucrative and effective tactic.
- Increased Use of Living Off the Land (LOTL) Techniques
Attackers are adopting more sophisticated techniques, such as using legitimate tools and software to further their attacks. LOTL tactics allow attackers to blend in with legitimate system processes, making it more challenging to detect.
- Growing Importance of Identity-Based Attacks
Identity-based attacks, where attackers target specific individuals or roles within an organization, have become increasingly common. This approach allows attackers to gain a foothold in the network and move laterally with ease.
- Continued Use of Fileless Malware
Fileless malware, which resides in memory rather than on disk, has remained a prevalent threat in 2023. This type of malware is particularly challenging to detect and remove.
- Increased Use of Removable Media
Attackers are increasingly using removable media, such as USB drives, to spread malware and steal sensitive data. This approach allows attackers to bypass traditional security controls.
Threat Hunting Strategies
To stay ahead of these evolving threats, organizations must adopt a threat hunting strategy that incorporates the following best practices:
- Use Threat Intelligence to Inform Your Hunting Efforts
Stay up-to-date with the latest threat intelligence and indicators of compromise (IOCs) to inform your hunting efforts.
- Implement a Hybrid Detection Approach
Combine traditional signature-based detection with behavioral and anomaly-based detection to identify and respond to unknown threats.
- Leverage Machine Learning and AI
Use machine learning and AI-powered threat hunting tools to identify patterns and anomalies in network traffic and endpoint data.
- Improve Incident Response Capabilities
Develop and regularly test incident response plans to ensure rapid detection and response to security incidents.
- Invest in Continuous Monitoring and Improvement
Continuously monitor and improve your threat hunting efforts through regular training, mentoring, and knowledge sharing.
Conclusion
Threat hunting is a critical component of any organization’s cybersecurity strategy. By understanding the latest threat hunting trends and tactics, and adopting a proactive approach to threat detection and response, organizations can stay ahead of the curve and minimize the impact of cyber threats.
