In part one of our two part blog series on the “String of Paerls” threat, we showed an attack involving a spearphish message containing an attached malicious Word doc. We also described our methodology in grouping similar samples based on Indicators of Compromise: static and dynamic analysis indicators. In this second part of the blog series we will cover the malicious documents and malicious executables. For the technical deep dive see the write up on the VRT blog here.
