Overview

Threat Intelligence is reputation information that helps responders make informed decisions on attacks and compromises.

Datadog curates commercial, open-source, and in-house threat intelligence indicators of compromise into categories and intents. Threat intelligence is updated at least once per day, per source. This data is used to enrich your logs and traces with relevant reputation information.

Threat Intelligence Lifecycle

Datadog collects threat intelligence across the following entity types. Each entity type has unique characteristics and a useful timeframe. This timeframe, or lifecycle, requires consideration when assessing the importance of a threat intelligence match on your data.

File Hashes: Unique Digital Fingerprints

File hashes function as unique digital fingerprints for specific files. When a file hash is marked as malware, it signifies the file’s exact content is harmful. The immutability of a hash, which is tied to its file’s content, ensures its consistent identification. As a result, a file hash tagged as malware retains this identification, provided the identification was a true positive.

Application Packages: Malware Risk in Distribution

Unlike immutable file hashes, application packages can vary in content and security, even under the same version number. Malicious actors may upload harmful packages mimicking legitimate ones, or they might compromise existing packages by introducing malware. The lifecycle of malicious packages is frequently long-lived, but not immutable.

Domains: Temporary Signatures

Unlike file hashes, domains identified as malicious are subject to change. They may undergo processes such as remediation, reassignment, or repurposing by various entities. While the lifecycle of malicious or suspicious domains is somewhat prolonged compared to IP addresses, it remains temporary and variable.

IP Addresses: Dynamic and Transient

IP addresses represent the most volatile element in threat intelligence, often changing reputations within a 24-hour cycle. Given their dynamic nature, particularly in residential and mobile networks where multiple hosts may be involved, it’s crucial to regularly reassess their status. Not all hosts connected to a low-reputation IP address are inherently malicious, underscoring the need for correlation.

Best Practices in Threat Intelligence

With threat intelligence, reputation is key, but it must be weighed alongside other evidence. Relying solely on IP and domain intelligence for blocking traffic is not recommended, with few exceptions. A balanced, evidence-based approach is essential.

Threat intelligence used in Detection Rules should reference the Datadog keys such as category and intent. Other keys should not be used.

Transparency in Threat Intelligence

Datadog ensures transparency by providing external links to external threat intelligence sources associated with a detection. Threat intelligence curated by Datadog is ingested into the Datadog platform for enrichment and detection. Datadog does not send customer data to threat intelligence sources.

The detections and enrichments are accessible in the UI and event JSON.
