Aufrufen tut ihr das ganze mit

viel spas!

Selbst gecoded?

[root]

Nope nicht selfcodet sondern bei hackhound gefunden

[KAS]

ey sorry bin bissel nublike aber für was is dieser source?

[L!x]

root kan nicht coden... wie soll der das auch machen

[sk!lled]

L!x deine kommentare kannste dir getrost sparen .


Seit lieber mal froh dass ihr den Source habt, der ist nämlich extrem nützlich


mfg sk!lled

[KAS]

ja für was is den der source? plz antworten^^

[root]

Hi also der ändert im file sowurde es mir erklärt den hash das antivre das file net erkennen oder so ich kann nur ein beispeil sagen macht man einen crypter mit runpe das file wird von sohpos erkannt macht man da sding rein ises fud

[w0red]

ich glaube, bin nicht zu 100% sicher(eher so 80%^^), er aktualisiert den header, also die größe, die im header steht, wird neu gemacht, wenn ihr an eine 100kb datei z.B. eure Stub dranhängt, das im pe header nicht immernoch 100kb steht sondern dann z.b 120kb, aber ich weiss es nicht genau, aufjedenfall wird eine datei, die als dropper erkannt wird, danach nicht mehr erkannt.

Googlet mal nach Pe-Header und erst wenn ihr das verstanden habt, solltet ihr diesen Source nutzen!
dann würden wir auch so blöde fragen nicht haben.
