Your malware reesrch new friend, KLara

While doing threat research, teams need a lot of tools and systems to aid their hunting efforts – from systems storing Passive DNS data and automated malware classification to systems allowing researchers to pattern-match a large volume of data in a relatively short period of time. These tools are extremely useful when working on APT campaigns where research is very agile and spans multiple months. One of the most frequently used tools for hunting new variants of malware is called YARA and was developed by Victor Manuel Alvarez while working for VirusTotal, now part of Alphabet.
