Man-in-the-Middle Ataklar\u0131<\/h2>\n
Man-in-the-middle (MITM) ataklar\u0131, siber sald\u0131rganlar\u0131n iki taraf aras\u0131ndaki ileti\u015fimi gizlice dinleyerek veya de\u011fi\u015ftirerek ger\u00e7ekle\u015ftirdi\u011fi sald\u0131r\u0131lard\u0131r.

Dark web, siber su\u00e7lular\u0131n anonim olarak faaliyet g\u00f6sterebildi\u011fi bir platformdur. Burada, fidye yaz\u0131l\u0131mlar\u0131 ve di\u011fer k\u00f6t\u00fc ama\u00e7l\u0131 yaz\u0131l\u0131mlar kolayca sat\u0131n al\u0131nabilir ve da\u011f\u0131t\u0131labilir.
