[VIDEO]Cracking TUTs

Recommended Posts

O sa incerc sa fac cate un astfel de tutorial o data pe saptamana (am foarte, foarte multe pe cap si prea putin timp liber), de la incepator spre avansat.

Prima parte (Absolute Begginer):

Uite...

Tie iti apare:

1. CPU - main thread.module CrackMe8 mie CPU - main thread module ntdll

2. Text strings referenced in CrackMe8:CODE mie Text strings referenced in ntdll:.text

P.S. (am dat search si nu am gasit stringul in Text strings referenced in ntdll:.text (ce imi apare mie))

P.S. Primul breakpoint trebuia pus pe linia cu JNZ, va dati voi seama. Scuzati-mi eroarea, nu am stat sa refac tutorialul doar pentru asta ^_^

Din cate am scris aici, breakpointul nu trebuie pus pe linia cu mov blabla (care contine stringul), ci cu un rand mai sus, pe linia cu JNZ'ul.

Succes !

10q vladiii am invatat ceva nou,adica faza cu breakpoint-ul,care arata parola pentru userul introdus.Eu am luat toate crack me de la sectiunea chalange intr-o zi si majoritatea lea-am facut.Doar cateva au rezistat.La acesta eu i-am dat direct reversing,orice combinatie fiind buna.

Tine-o tot asa.
