Zeus Sphinx
Intelligence Profile
This family describes the vanilla Zeus-variant that includes TOR (and Polipo proxy). It has an almost 90% overlap with Zeus v2.0.8.9.
Please note that IBM X-Force decided to call win.zloader/win.zeus_openssl "Zeus Sphinx", after mentioning it as "a new version of Zeus Sphinx" in their initial post in August 2016. Malpedia thus lists the alias "Zeus XSphinx" for win.zeus_openssl - the X to refer to IBM X-Force.
