Now on the Green Room at #VB2019, @eldracote @anshirokova will present "Geost botnet. The discovery story of a new Android banking trojan from an OpSec error", a work also done with @MaryJo_E ! 
The Geost botnet was found by investigating the traffic of a different botnet: #htbot also known as proxyback. This htbot botnet offers a proxy service for users in the underground.
The Geost operators were using htbot to access the command and control servers from Geost (thinking they were hiding themselves).
