Amadey | Amadey is a botnet that appeared around October 2018 and is being sold for about $500 on Russian-speaking hacking forums. It periodically sends information about the system and installed AV software to its C2 server and polls to receive orders from it. Its main functionality is that it can load other payloads (called "tasks") for all or specifically targeted computers compromised by the malware. | No Attribution |

Nymaim | Nymaim is a trojan downloader. It downloads (and runs) other malware on affected systems and was one of the primary malware families hosted on Avalanche. Nymaim is different in that it displays a localized lockscreen while it downloads additional malware. Nymaim is usually delivered by exploit kits and malvertising. | No Attribution |
