Will be decoded by the next version of Malzilla
I think I know how I can process it.
The sub-project name is "Kalimero processor". As for now, it gets all the relevant HTML-part data. It remains now to implement passing the data to JS engine.
Because of urgency, Kalimero will probably create template from HTML, the same kind of template we already have in Decoder tab, and Decoder will use it like any other template. This is probably the fastest way to get deobfuscation of this kind of scripts implemented.
