FortiGuard Labs has been actively monitoring FALLCHILL, validating all its IOCs (indicators of compromise), and providing protection for our customers. In a previous post we provided a high level overview of FALLCHILL. In this research report we dig even further, providing a deep dive analysis of the FALLCHILL Remote Administration Tool (RAT) in order to shed additional light on this threat, and thereby help our customer and the security community at large defend against this threat and similar threats.
FortiGuard Labs has been actively monitoring FALLCHILL and validating all IOCs, whether we discovered them ourselves through one of our millions of sensors deployed around the world, or collected from the hundreds of threat sharing feeds we subscribe to. Our comprehensive threat information-sharing program includes Governments, Certs, and Strategic Partners from around the world.
