Kolejne modele Panzerfausta, odpowiednio: 60, 100, 150, różnił
|
|
||||||
kaliber głowicy i wielkość ładunku miotającego. Konstrukcja i
|
|
||||||
mechanizm nie ulegał istotnym zmianom, z racji wzrastania zasięgu
|
|
||||||
broni modyfikacjom ulegały nastawy celowników. Jedynie we wzorze 150
|
|
||||||
wprowadzono (a był to już początek 1945 roku) wielokrotne użycie
|
|
||||||
wyrzutni rurowej. Osiągnięto to przez umieszczenie ładunku
|
|
||||||
miotającego w głowicy oraz przez wzmocnienie rury. W wyniku problemu z
|
|
||||||
transportem model ów nie wszedł do walki. Model 250 (o teoretycznym
|
|
||||||
zasięgu 250 m) z racji zakończenia wojny nie opuścił desek
|
|
||||||
kreślarskich nigdy nie wchodząc nawet w fazę prototypową.

You are doing a forensics evaluation of a linux box that you know has

used by the attackers to hide data on box that that was exfiltrated.

You dissamble the file and find the x86 assembly shown below (from Ida)

HINT: The function was orginally defined as void convert_buf(unsigned
