Qu'est-ce qui vous donne l'impression d'être malveillant? –
@ m.edmonson - J'ai vu des scripts malveillants obscurcis où les codes hexadécimaux étaient évalués dans d'autres commandes. Il n'est pas inconcevable que cela puisse être malveillant (d'un coup d'œil), bien que je sois d'accord avec vous que l'inspection occasionnelle réfute cela. Peut-être que la palette de couleurs est dure pour les yeux. –
Je sais que c'est vieux, mais si vous êtes toujours là, @Fred, où avez-vous trouvé ce code? –
