Automatically curate open source yara rules and run scans

Installation

go get github.com/EFForg/yaya
cd $GOPATH/src/github.com/EFForg/yaya

Dependencies

Yaya depends on the following packages outside the standard library:

• https://github.com/go-git/go-git
• https://github.com/hillu/go-yara
• https://github.com/jinzhu/gorm

You must also install the yara4 C libraries. We recommend you install these from source with the following command:

wget https://github.com/VirusTotal/yara/archive/refs/tags/v4.1.0.tar.gz && mkdir yara && cd yara && tar xf ../v4.1.0.tar.gz \
    && cd yara-4.1.0/ && ./bootstrap.sh && ./configure --enable-cuckoo --enable-magic --enable-dotnet && make && sudo make install && sudo ldconfig
