How do you use threat intelligence in malware analysis?

Threat intelligence is the collection and analysis of information about potential or current attacks that threaten the safety of an organization or its assets. For example, a cybersecurity team might receive threat intelligence that a specific type of malware is targeting their industry, enabling them to update their firewalls and educate employees about phishing emails carrying the malware.

Effective TI is a measure of the number of signals you are able to assess and derive if the threat is real. Specifically in the multivector threat era where the threat landscape is so sophisticated and modern. More the number of signals more effective is your TI.

Threat intelligence refers to information that helps organizations understand and mitigate cybersecurity threats. It involves gathering, analyzing, and interpreting data about potential or current cyber threats, including information about the tactics, techniques, and procedures (TTPs) used by threat actors, indicators of compromise (IOCs), and the motivation behind various cyber attacks. The primary goal of threat intelligence is to provide actionable insights that enable organizations to anticipate, detect, and respond to cyber threats effectively.

Strategic intelligence: This type of threat intelligence focuses on understanding the broader trends and motives of threat actors, as well as the overall cybersecurity landscape. Strategic intelligence helps organizations make informed decisions about long-term security strategies and risk management. Operational intelligence: Operational threat intelligence involves real-time data about specific threats, including ongoing attacks, emerging vulnerabilities, and potential risks to an organization's systems and networks. It helps security teams respond promptly to immediate threats and vulnerabilities.

Tactical intelligence: Tactical threat intelligence provides detailed insights into the specific tools, techniques, and procedures used by threat actors. It helps security teams understand the modus operandi of attackers and develop effective defense mechanisms and countermeasures. Threat intelligence is gathered from various sources, including open-source intelligence, dark web monitoring, security vendor reports, government agencies, industry-specific information sharing and analysis centers (ISACs), and internal security monitoring tools. By leveraging threat intelligence, organizations can proactively identify and address potential cyber threats, enhance their security posture, and mitigate the risk of cyber attacks and data breaches.

Collecting threat intelligence involves gathering data from various sources such as cybersecurity feeds, hacker forums, dark web, incident logs, and SIEM systems. For instance, a security analyst might use automated tools to monitor and analyze chatter on a dark web forum where a new exploit kit is discussed, allowing the organization to preemptively strengthen their defenses against this specific threat.

Learning from attacks, collaborating with partners and governments, AI/ML based threat research, assessing as many signals from your platform powers any TI.Chosing right TI feed depends on these capabalities and investments of the TI provider. BYOML is something that you can leverage to comprehensively hunt your environment for threats specific to your org/industry.

Open-source intelligence (OSINT): Monitor publicly available sources such as news articles, social media platforms, blogs, and forums to gather information about emerging threats, vulnerabilities, and cyber attacks. Information sharing and analysis centers (ISACs): Participate in industry-specific ISACs or other information-sharing communities to exchange threat intelligence with peers and industry partners. These platforms facilitate the sharing of threat data and best practices among trusted organizations.

Dark web monitoring: Monitor the dark web and underground forums to identify discussions and activities related to potential cyber threats, data breaches, and the sale of stolen data or credentials. Dark web monitoring helps in understanding the tactics and activities of threat actors in illicit online communities. Security vendors and research reports: Stay updated with threat intelligence reports, research papers, and analyses published by reputable security vendors, research organizations, and cybersecurity experts. These reports provide insights into the latest cyber threats, attack vectors, and emerging vulnerabilities.

Government and law enforcement agencies: Access threat intelligence from government agencies, such as national cybersecurity centers and law enforcement organizations, which often share information about significant cyber threats, state-sponsored attacks, and global cybercrime trends. Internal security monitoring tools: Utilize security monitoring tools, such as Security Information and Event Management (SIEM) systems, intrusion detection systems (IDS), and intrusion prevention systems (IPS), to collect and analyze real-time data about potential security incidents and threats within your organization's network and systems.

Threat intelligence is used in malware analysis by providing context and indicators of compromise (IoCs) that help analysts understand malware behavior and origins. For example, if intelligence indicates a rising trend in ransomware targeting healthcare systems, analysts can scrutinize suspicious code for related IoCs, enabling quicker identification, understanding of the attack vector, and development of specific countermeasures to protect their networks.

Integrating threat intelligence into malware analysis transforms it from a technical exercise into a strategic endeavor. It’s not just about dissecting a piece of malware, but contextualizing it within the broader threat landscape. By leveraging threat intelligence, analysts can discern the ‘why’ and ‘how’ behind a malware attack, aligning defensive measures more precisely with attacker methodologies. This integration elevates malware analysis from a reactive post-mortem analysis to a proactive tool, guiding the development of more adaptive and predictive security postures. It's a shift from dissecting code to understanding adversaries, turning malware analysis into a strategic chess game against threat actors.

Using threat intelligence in malware analysis enhances the effectiveness of security measures by enabling proactive defense. For example, if threat intelligence reveals a new malware variant exploiting a software vulnerability, analysts can quickly deploy targeted antivirus signatures and network rules to detect and block this threat, reducing the time the malware has to cause damage and improving the organization's overall security posture.

Malware analysis becomes difficult task when the threats are unknown. You can get visibility on IOC'S using TI and hunt for them in your environment and get control and visibility. However TI with comprehensive IOA's empower you to deal with the unknowns.

Improving threat intelligence skills requires staying current with trends, regularly engaging with the cybersecurity community, and continuous learning. For instance, participating in threat intelligence forums, attending relevant webinars, and practicing with threat intelligence platforms can sharpen analytical abilities. Simulating threat scenarios and using sandbox environments to dissect new malware types also hones the practical skills needed for real-world threat intelligence analysis.

Enhancing threat intelligence skills is a journey of continuous learning and adaptation. It requires an insatiable curiosity and a relentless pursuit of knowledge across a wide range of domains. In addition to keeping up-to-date with the latest trends and techniques, one must also cultivate a diverse skill set encompassing technical, analytical, and communication abilities. Engaging in communities of practice and embracing hands-on experiences, whether through simulations, exercises, or real-world application, remains key. As the threat landscape evolves, so must our skills, ensuring that we're not just keeping pace but staying ahead of adversaries.

When improving threat intelligence skills, consider also developing soft skills such as communication and collaboration, as they're vital for effectively sharing insights. For example, presenting findings clearly to non-technical stakeholders or collaborating with international cybersecurity groups can enhance your threat response strategies and build a comprehensive defense framework by integrating diverse perspectives and experiences from across the global security community.

When it comes to threat intelligence in malware analysis, it's essential to recognize that intelligence is not just a product, but a process – a cycle of constant learning, application and adaptation. The integration of threat intelligence into security practices should not be seen as an added layer, but as a fundamental pillar, ingraining a mindset that continuously seeks to understand and anticipate the adversary. The real power lies in the ability to transform data into wisdom, guiding not just technical strategies but shaping a comprehensive, informed approach to cybersecurity. This is the frontier where technical prowess meets strategic foresight, where data points become a narrative that informs and empowers a robust defense strategy.
