I am downloading a PDF file, and would like to know how to diagnose security vulnerabilities in that file.


The last version of Google Chrome is giving me the following warning on a PDF download:

enter image description here

Trying to learn more about the alert brings me to this help page, which explains that the alert can be triggered by either

a malicious, unwanted, or uncommon file


the website you tried to download the file from has been known to distribute malware.

I would like to sort out which one it is, and am therefore looking for a way to scan the PDF file for potential vulnerabilities.

My guess is that any tool that indicates the existence of executable code in the file would do, but does such a tool exist?

peepdf and pdf-parser.py from Didier Stevens. Various online malware scanners which support PDF is good to try either.

  • Thank you very much. And your third link includes @Jedi's link to VirusTotal.

  • @Fr. Yes, VirustTotal is most well known in online malware scanners which anyone shouldn't forget to mention!
