How to generate signatures for a set of binaries (more than two binaries)

Hi all,

Thank you for your wonderful work. I am trying to use VxSig to generate AV signatures for a few malware families, where each family consists of multiple binaries (>2).

If I understand correctly, VxSig takes a pair of binaries as input, locating the common parts, and finally generate YARA rules to represent them.

Now how to generate signatures for a pair of binaries is clear. However, I am still confused about how to use VxSig to generate YARA rules for a set of binaries (more than two binaries). Actually I have some initial ideas, but I am not sure.

Could you give me some suggestions, or, what is the best practice of dealing with more than two binaries?

Much thanks in advance!
