MAXIMIZING THE VALUE OF INDICATORS OF COMPROMISE AND REIMAGINING THEIR ROLE IN MODERN DETECTION

Summary from the TLDR InfoSec newsletter

File hashes, IP addresses, and domains are usually seen as indicators of compromise (IoCs), but they have limited value in investigations because adversaries can easily alter them. These IoCs can be more insightful if supplemented with additional contextual data like fuzzy hashes, GeoIP information, and domain reputation. As AI enhances malware developers' abilities, IoCs will no longer serve as standalone alerts but will evolve into data points that help build a comprehensive understanding of a threat actor's behavior.
