## **Malloc Hook**

Kama unavyoweza [Tovuti Rasmi ya GNU](https://www.gnu.org/software/libc/manual/html\_node/Hooks-for-Malloc.html), kipengele cha **`__malloc_hook`** ni kipande kinachoelekeza kwenye **anwani ya kazi itakayoitwa** wakati wowote `malloc()` inaitwa **iliyohifadhiwa kwenye sehemu ya data ya maktaba ya libc**. Kwa hivyo, ikiwa anwani hii itabadilishwa na **One Gadget** kwa mfano na `malloc` inaitwa, **One Gadget itaitwa**.

Kuita malloc inawezekana kusubiri programu iite au kwa **kuita `printf("%10000$c")`** ambayo inaleta idadi kubwa ya baiti hivyo kufanya `libc` kuita malloc kuwahifadhi kwenye rundo.

Maelezo zaidi kuhusu One Gadget katika:

Tafadhali elewa kwamba vitanzi vime **lemazwa kwa GLIBC >= 2.34**. Kuna njia nyingine za kutumia kwenye toleo za kisasa za GLIBC.
