DMA Hile Cihaz\u0131 Nedir ve Neden Bu Kadar Pahal\u0131?<\/h2>\n\n

DMA kartlar\u0131, bilgisayar\u0131n anakart\u0131ndaki PCIe yuvas\u0131na tak\u0131lan ve CPU ile i\u015fletim sistemini tamamen atlayarak do\u011frudan RAM’e eri\u015fim sa\u011flayan donan\u0131m cihazlar\u0131d\u0131r.

Riot Games’in Aral\u0131k 2025’teki g\u00fcvenlik g\u00fcncellemesinde belirtti\u011fi \u00fczere, DMA cihazlar\u0131 y\u0131llard\u0131r “en etkili ve pahal\u0131” hile y\u00f6ntemi olarak biliniyor.<\/p>\n\n

Riot Games’in T\u00fcrk\u00e7e g\u00fcvenlik a\u00e7\u0131klamas\u0131na g\u00f6re IOMMU, “RAM’i koruyan bir g\u00fcvenlik g\u00f6revlisi” gibi \u00e7al\u0131\u015f\u0131yor: belle\u011fe eri\u015fmeye \u00e7al\u0131\u015fan her cihaz\u0131n kimli\u011fini kontrol ediyor ve yetkisiz olanlar\u0131 engelliyor.<\/p>\n\n

G\u00fcncelleme sonras\u0131 s\u00fcre\u00e7 \u015f\u00f6yle i\u015fliyor:<\/p>\n\n

  • Oyun i\u00e7inde bir IOMMU yeniden ba\u015flatma uyar\u0131s\u0131<\/strong> tetikleniyor.<\/li>\n\n\n\n
  • Bu uyar\u0131dan sonra DMA firmware’i tamamen kullan\u0131lamaz hale geliyor.<\/li>\n\n\n\n
