unable to decode streams in pdf
Hi Guys,
I was laying my hands on a malicious pdf and was unable to decode the streams either using pdf-parser or using pdftk. Pls can you have a look at it.

pdf-parser decodes the fike properly. After decoding you find 5 JS sections.

Is it highly obfuscated?

Re: unable to decode streams in pdf
I was just wondering what that other things mean?
There were three distinct sects of '\x??' on the file.... Is it added just like that or does it mean something?
