2010 Gozi v2.0, Gozi ISFB, ISFB, Pandemyia(*)
2014 Dreambot (Gozi ISFB variant)

In 2014, a variant of Gozi ISFB was developed. Mainly, the dropper performs additional anti-vm checks (vmware, vbox, qemu), while the actual bot-dll remains unchanged in most parts. New functionality, such as TOR support, was added though and often, the Fluxxy fast-flux network is used.

See win.gozi for additional historical information.
