Context

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. Zeus Sphinx on the one hand has the following versioning ("slow increase") - 2015/09 v1.0.1.0 (Zeus Sphinx size: 1.5 MB) - 2016/02 v1.0.1.2 (Zeus Sphinx size: 1.5 MB) - 2016/04 v1.0.2.0 (Zeus Sphinx size: 1.5 MB) Zeus OpenSSL on the other hand has the following versioning ("fast increase") - 2016/05 v1.5.4.0 (Zeus OpenSSL size: 1.2 MB) - 2017/01 v1.14.8.0 (Zeus OpenSSL size: 1.8 MB) - 2017/01 v1.15.0.0 (Zeus OpenSSL size: 2.2 MB)
