Whenever we want to proactively hunt for malware of interest for threat intelligence purposes, YARA is the swiss-army knife that makes the work of malware researchers and threat intelligence Researchers easier.

We will talk about leveraging the YARA to detect the future version of the malware.
Malware developers work just like legitimate software developers, aiming to reduce the time wasted on repetitive tasks wherever possible. That means they create and reuse code across their malware. This has a pay-off for malware hunters and threat intelligence researchers, we can learn how to create search rules to detect this kind of code reuse, Traditional Yara rules are written on strings, but if we implement code leveraging YARA code reuse rules in addition to the strings rule the rule will last decades. We can leverage that for finding future malware from the same authors using their digital code fingerprints.
