Мичиганский университет представил миру свою версию программы для сканирования портов под названием Zmap. Чем этот сканер привлек наше внимание? Да собственно ничем, кроме того, что с одного-единственного ПК, подключенного к сети по гигабитному каналу можно просканировать все адресное пространство IPv4 всего за несколько минут.
Сразу хочу сказать, что ни к каким бот-сетям ZMap не имеет никакого отношения. Чем же тогда обуславливается его скорость? ZMap работает на пределе теоретических возможностей Ethernet, задействуя гигабитный канал полностью. Особенность заключается в том, что Ethernet-кадры генерируются минуя стек TCP/IP. На обычном ПК с гигабитным соединением программа способна сканировать со скоростью 1,4 млн пакетов в секунду.
Создатели ZMap надеятся, что их детище будет полезно для исследователей интернета. Так же его можно использовать для изучения использования новых протоколов, мониторинга сервисов и изучения структуры всемирной сети.
