One of the key aspects of cybersecurity is being able to detect and prevent cyberattacks before they cause significant damage or loss. This requires having a good understanding of the indicators of compromise (IOCs) that can reveal the presence or activity of malicious actors or malware on a system or network.
An IOC is a piece of information that indicates a potential or actual security incident. It can be anything that deviates from the normal or expected behavior or state of a system or network. For example, an IOC can be a suspicious file name or hash value, a malicious domain name or IP address, a registry key or process name associated with malware, or a network connection or traffic pattern that indicates command-and-control (C2) communication.
By collecting and analyzing IOCs from various sources, cybersecurity professionals can identify the nature and scope of an attack, determine its impact and severity, and take appropriate actions to contain and eradicate it. Moreover, by sharing IOCs with other security teams or communities, they can also help prevent future attacks or limit their spread.
What are the types of IOCs?
IOCs can be classified into different types based on their source or level of abstraction. Some of the common types of IOCs are:
Network IOCs: These are IOCs that relate to network-level activities or artifacts associated with an attack. They include domain names or IP industry groups, and government agencies. These sources can offer different types and formats of IOCs, such as CSV, JSON, XML, STIX, TAXII, etc. These sources can also have different access and usage policies, such as free, paid, open, or restricted. Some of the common sources of IOCs are:

Here are some frequently asked questions and answers related to the topic of downloading IOCs:
What is the difference between IOCs and IOAs?
IOCs (indicators of compromise) are pieces of information that indicate a potential or actual security incident on a system or network. IOAs (indicators of attack) are pieces of information that indicate the intent or objective of an attacker or malware on a system or network. IOCs are more reactive and retrospective, while IOAs are more proactive and predictive.
What is the difference between atomic and composite IOCs?
Atomic IOCs are single pieces of information that can indicate a security incident, such as a file hash, a domain name, or an IP address. Composite IOCs are combinations of multiple pieces of information that can indicate a security incident, such as a file hash and a registry key, a domain name and a URL, or an IP address and a port number. Composite IOCs are more specific and contextual, while atomic IOCs are more generic and ambiguous.
What is the difference between STIX and TAXII?
STIX (Structured Threat Information Expression) is a standardized language and format for expressing and exchanging threat intelligence and IOCs. TAXII (Trusted Automated Exchange of Intelligence Information) is a standardized protocol and service for transmitting and receiving threat intelligence and IOCs. STIX defines what to share, while TAXII defines how to share.
