NYMAIMNymaim

Nymaim was discovered in 2013. At that time it was only a dropper used to distribute TorrentLocker. In February 2016 it became popular again after incorporating leaked ISFB code, dubbed Goznym. When dropper obtains C&C address, it starts real communication. It downloads two important binaries and a lot more: payload – banker module (responsible for web injects – passive member of botnet); optional bot module (it is trying to open ports on a router and become an active part of a botnet. When it fails to do so, it removes itself from a system).
