Fanny

Fanny is an Equation Group worm. The provided content identifies it as an earlier Equation Group malware family/toolset alongside EQUATIONDRUG, DOUBLEFANTASY, and GRAYFISH, and states that it was later linked to Stuxnet through shared exploits. Specifically, the content says Fanny used two Stuxnet zero-days one to two years before Stuxnet, including the Windows LNK exploit CVE-2010-2568 and a privilege-escalation exploit embedded in Stuxnet Resource 207. The content further states that these shared exploits helped connect Stuxnet, Duqu, and the Equation Group, and that Kaspersky researchers noted shared coding practices between Stuxnet and Equation developers. No additional high-confidence details on Fanny’s infection vector, victimology, industries targeted, or specific indicators of compromise are provided in the supplied content.

Equation Group

Having originally uncovered the Equation group in February 2015, we’ve taken a look at the newly released files to check for any connections with the known toolsets used by Equation, such as EQUATIONDRUG, DOUBLEFANTASY, GRAYFISH and FANNY.

Equation

At the same time, Stuxnet was connected to Duqu and, as we found more recently, the Equation group, through their exploits originally used by the Fanny worm.
