i tried a quick google to find the article i learned about this tool from, because it actually gave a walkthrough of its use for precisely the situation you describe. i couldn't find the article i remembered, but the utility, pdf-tools, should provide you with all the capabilities you need to investigate a pdf file for potential malware traits. the didier stevens guy's website actually covers some techniques for analyzation, and lists some common attributes to search for. http://blog.didierstevens.com/programs/pdf-tools/ a simpler way to know may just be the contents of the pdf, if you can convert it into flat text file, you should be safe to comfortably browse the contents to determine if the pdf is at all related to the topic of the wiki. if it's not, it has no place there regardless of whether or not it contains malware, and i would be pretty confident at that point that it probably is. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
