حزمة ELF لـ Zeek

تنفّذ هذه الحزمة:

باختصار!

إذا كان لديك zkg وسبق لك تشغيل...

zkg autoconfig

...فيمكنك تثبيت هذه الحزمة كما يلي:

sudo zkg install zeek-elf

الآن في أي سكربت Zeek، ما عليك سوى تحميل الإضافة وستعمل مباشرة:

@load Zeek/ELF

الأحداث الجديدة لهذه الإضافة موجودة في events.bif.

البناء والتثبيت

يمكن بناء هذه الإضافة باستخدام:

./configure --zeek-dist=/your/zeek/src/dir
make
sudo make install

استخدام ELF

ملف pcap المستخدم في الاختبار:

https://github.com/corelight/zeek-elf/blob/master/tests/Traces/all_executables.pcap

الملفات الثنائية في هذا الـ pcap مأخوذة من:

https://github.com/JonathanSalwan/binary-samples

بعد التثبيت، يمكن تحميل هذه الإضافة باستخدام سكربت Zeek التالي:

@load Zeek/ELF

event file_elf(f: fa_file)
    {
    print "ELF";
    }

event file_elf_header(f: fa_file, m: Zeek::ELFHeader)
    {
    print "====";
    print "ELF HEADER";
    print m$signature;
    print "====";
    }

يجب أن يبدو الناتج كما يلي:

% zeek -r pcaps/all_binaries.pcap -C elf.zeek
