CenturyLink Threat Research Labs has been tracking the Mylobot botnet, a sophisticated malware family that is categorized as a downloader. What makes Mylobot dangerous is its ability to download and execute any type of payload after it infects a host. This means at any time it could download any other type of malware the attacker desires. A detailed walkthrough and reverse engineering analysis of Mylobot was first reported in June by Deep Instinct. During the time we have been monitoring Mylobot we have observed it downloading the Khalesi malware as a second stage to infected hosts. Kaspersky Lab reports that the information stealing Khalesi malware is one of the top downloaded malware families in 2018.
