VERY IMPORTANT

Recently, we have been observing another bot, with the design reminding of ZeuS, that seems to be fairly new (a 1.0 version was compiled at the end of November 2019), and is actively developed. Since the specific name of this malware was for a long time unknown among researchers, it happened to be referenced by a generic term Zloader/Zbot (a common name used to refer to any malware related to the ZeuS family). Our investigation led us to find that this is a new family built upon the ZeuS heritage, being sold under the name "Silent Night". In our report, we will call it "Silent Night" Zbot.
