Does a corrupted pdf still become a virus if the binary for a virus still exists but the pdf structure is corrupted?

  • you get -3 when your question is so garbled, that it's unreadable – schroeder Aug 28 '17 at 9:06
  • the answer is obvious: viruses need to be executed - if they cannot be executed, then they are not a virus - which means, according to your question, it depends on how the PDF is corrupted – schroeder Aug 28 '17 at 9:07
  • I suspect you are asking if a PDF containing a virus remains capable of harm if the PDF file itself is corrupt. However what you actually asked is whether the one can be transmuted in the other - which is semantic gibberish. – symcbean Aug 28 '17 at 11:31

By definition, a PDF that contains a virus is corrupt. (I'm ignoring the case where a PDF might contain a JPG or font that houses a virus.) So yes, a virus in a corrupted PDF is still viable and can infect a client that parses it.
