1. Introduction to Cyber Threat Intelligence
It refers to collecting, analyzing, and disseminating information about cyber threats and vulnerabilities. It helps organizations identify, assess, and mitigate the risks posed by cyber threats. Cyber threat intelligence can come from various sources, including government agencies, private sector companies, and open-source information.
Cyber threat intelligence is important because it enables organizations to protect themselves and their customers from cyber-attacks. It allows them to understand cybercriminals' tactics, techniques, and procedures and develop effective countermeasures to prevent or mitigate attacks. It also helps organizations respond to and recover from cyber incidents more quickly and effectively.
One real-life example of the importance of cyber threat intelligence occurred in 2017 when the global WannaCry ransomware attack affected over 200,000 computers in 150 countries. The attack exploited a vulnerability in older versions of the Windows operating system, spreading rapidly through a worm. Many organizations were unprepared for this attack, and as a result, they suffered significant disruptions to their operations. Had these organizations been utilizing cyber threat intelligence, they may have been able to identify the vulnerability and patch their systems before the attack occurred.
2. Types of Cyber Threats
There are several types of cyber threats, including, but not limited to:
Malware is a type of software that is specifically designed to disrupt, damage, or gain unauthorized access to a computer system. It can take many forms, including viruses, worms, trojans, and spyware. Malware can be installed on a victim’s computer through various means, such as email attachments, web browsing, or the exploitation of vulnerabilities.
Ransomware is malware that encrypts a victim’s files, making them inaccessible until a ransom is paid to the attackers. Ransomware attacks can be particularly devastating for organizations, as they can disrupt critical operations and lead to significant financial losses. In 2017, the global WannaCry ransomware attack affected over 200,000 computers in 150 countries, causing widespread disruption and financial damage.
Phishing attacks are a type of cyber attack that involves the use of fraudulent emails or websites to trick victims into revealing sensitive information, such as passwords or financial data. These attacks often take the form of spam emails that appear to be from legitimate sources and can be very convincing. According to a report by the Anti-Phishing Working Group, there were more than 1.2 million phishing attacks in the first half of 2020 alone.
Vulnerabilities are weaknesses in computer systems or networks that attackers can exploit to gain unauthorized access or perform malicious actions. These vulnerabilities can be found in software, hardware, or firmware and can be exploited through various means, such as malware or phishing attacks. Organizations need to identify and address vulnerabilities in their systems to prevent attacks.
Exploits are methods or techniques to exploit vulnerabilities to gain unauthorized access to a system or perform other malicious actions. Cybercriminals or security researchers can develop exploits, delivered through various means, such as email attachments, web browsing, or network-based attacks.
Cyber espionage is using cyber means to gather sensitive information for political, economic, or military advantage. This can include the theft of intellectual property, trade secrets, or classified information. Cyber espionage can be conducted by nation-states, criminal groups, or other actors, and it can have significant consequences for targeted organizations and individuals.
Advanced persistent threats (APTs) are sophisticated cyber attacks often carried out by nation-states or other highly skilled actors. APTs typically involve using multiple vulnerabilities and exploits to gain unauthorized access to a system and maintain a presence within it over an extended period. APTs are often difficult to detect and defend against and can have serious consequences for targeted organizations.
Denial of service (DoS) attacks involve overwhelming a target’s resources, such as its web servers or network bandwidth, to prevent legitimate users from accessing the service. DoS attacks can be carried out using various methods, including distributed denial of service (DDoS) attacks, in which multiple systems are used to flood the target’s resources.
Network intrusions are unauthorized access to a network or system. They can be carried out through various means, including malware, phishing attacks, and the exploitation of vulnerabilities. Network intrusions can result in the theft of sensitive data, the disruption of operations, or other negative consequences for the targeted organization.
3. Gathering Cyber Threat Intelligence
The following steps help in gathering intelligence :
Indicators of compromise (IOCs) are signs or evidence that an attacker has compromised a system or network. IOCs can take many forms, such as IP addresses, domain names, file hashes, or other data types that can be used to identify malicious activity. IOCs are an important part of cyber threat intelligence, as they can help organizations identify and respond to attacks more quickly.
For example, suppose an organization is monitoring its network traffic for indicators of compromise, and it detects a connection to a known malicious IP address. In that case, it can block the connection and prevent further damage. It can also use the IOC to investigate and determine the compromise’s extent.
Cyber threat intelligence feeds are sources of information about cyber threats and vulnerabilities that are updated in real-time or regularly. These feeds can come from various sources, such as government agencies, private sector companies, and open-source intelligence. Cyber threat intelligence feeds can be used by organizations to stay up-to-date on the latest threats and to identify indicators of compromise in their systems.
Threat intelligence platforms are software tools that collect, analyze, and disseminate cyber threat intelligence. These platforms often incorporate multiple sources of intelligence, such as threat feeds, open-source information, and proprietary data, and they provide features such as data visualization, threat scoring, and incident response capabilities. Threat intelligence platforms can help organizations manage and respond to cyber threats more effectively by providing a centralized location for storing and analyzing intelligence data.
4. Using Cyber Threat Intelligence
