    DISABLE" ALL user web/internet addresses/sites in a PDF?

    HistorianRigemental

      Professionally & Personally - I use, make, and Read many PDF files daily [reports, documents, & books]; I have many "many" thousands of PDF documents in my Archives.

       

      A. Background:

       

      1.    I have heard, since Acrobat 5, many security specialist have deemed JAVA as a THREAT; and PDF as a security concern! Recently Reported Home Land Security has deemed JAVA as an on-going "continuing high threat", in spite of se7u11; reported that DHLS expressed that 28% of reported ATTACKS were from Adobe Acrobat PDF files embedded user malicious software code [ever growing numbers of attacks]. <PDF security is a major growing DOD concern!>

       

      2.    To my great surprise from "IT" professional who disabled JAVA in his Department's systems, the current Security Software and specific program updates offer no real solution or resolutions to this ongoing security problem. I understood that Virus and Trojan Checkers do not check malicious software code hidden inside PDF files, and software updates do not remove or make safe the malicious software code in the actual PDF – thus it remains a potentially very DISTRUCTIVE-DATA-BOMB just setting in your databases awaiting to be activated at some future date.

       

      3.    "This is very tedious and time consuming!" I have since disabled JAVA in my Adobe Acrobat and run each PDF through "PDF OPTIMIZER" - Discarding all User Data, User Objects, and especially User JAVA Codes – and disable my LAN internet connection -- before utilizing it. I don’t know if this is of any good or not – but I feel safer.

       

      B. PROBLEMS & QUESTIONS (I’ve given each question its own string to assist with preventing confusion)!

       

      2.    Using an Adobe Acrobat program function - how can I "REMOVE & DISABLE" ALL [100%] of user noted, embedded, or hidden web/internet addresses/sites in a PDF? What is Adobe's solution?

          Do not re-post your question multiple times. It's not going to help you get an answer...

           

          Also, please stop spreading incorrect information. PDF files do not contain any Java code and there's no need to disable JavaScript in Acrobat/Reader.

            try67;

             

            I do so appreciate your assistance…

             

            Each of my “QUESTIONS” are specific, direct, and unique – Please Read THEM and answer if you can – if you do not have the technical ability or understanding of my question please do not “scold” me!

             

            Although I have used in business and own computers since the 1970’s [built one myself], I’ve not had to concern myself with programming since, DOS, Lotus/IBM/Apple Basic and COBAL --- especially after XP release I gave up even trying to figure what each does. I did not mean to offend as to which specific JAVA version and/or product is the problem, since I personally have no CLUE – and today totally depend upon goodwill of smart guys like you.

             

            Specifically why recently DHLS [IT security folks and DOD for many years] is saying that Malicious Software code in PDF files is such a big threat and responsible for 28% of the systems attacks I do not know the technicalities or reasoning of these assertions – except it had something to do with JAVA CODE/JavaScript[?] contained inside the actual PDF which virus software doesn’t detect or destroy?  I do not know if it is the Additional CODE placed inside the PDF by the bad actor and/or the changing of actual Adobe Program Code is the problem? I may be chasing may tail!

             

            My biggest concern for many years into the future -- is protecting my very large PDA database/Archive, multiple Systems, my personal information, and to try to the best of my ability to not pass PDF having within it Malicious Software CODE [JAVA CODE/JavaScript?] put into it by a bad actor.

             

            Since my PDF database Archives [and back-ups] is many terabytes – it is impossible to “import” each PDF into Acrobat and run PDF Optimizer (removing Adobe known user placed codes and data) – as I am doing now.

             

            This is again my very specific question -  Using an Adobe Acrobat program function - how can I "REMOVE & DISABLE" ALL [100%] of user noted, embedded, or hidden web/internet addresses/sites in a PDF?

             

            Thank you so very much for your knowledge, help, and interest.

              Not Java. Please stop calling it Java, or a version of Java. If you continue to mix them up you will confuse us, you, and future readers.

                Well, for starters you should stop prefacing each question with 3 to 4 identical paragraphs of copied&pasted infomation which you've posted already in other threads. Maybe then people would arrive to the actual question you're asking.

                Also, you might want to post all of your questions in a single thread...

                 

                And you should try reading the responses given to you and stop thinking there's Java code in PDF files. There isn't!


                Now, you asked:

                Using an Adobe Acrobat program function - how can I "REMOVE & DISABLE" ALL [100%] of user noted, embedded, or hidden web/internet addresses/sites in a PDF?

                What do you mean? The actual text? Links? Form fields? Something else? If you want help, you need to ask clear questions.

                  How should I know? I don't know what you're talking about...

                    Since you are worried by something to do with PDFs and can't tell us what it is, perhaps you could refer us to one of these reports and we can see if there are any facts to be found in it.

                      YES - understand your confusion. Sorry.

                       

                      Since this one transaction even caused confusin - I was consurnd addressing all questions one transaction would also confuse everyone - or not answer every question - and since each of my specfic qestions needed "back ground" as to the primus of the question since I could not be assured that "you" would read and respond to them all personnally [much less care].

                       

                      Links, mail accounts, email addresses, web links, any of the such that could direct reader or opener of PDF to "BAD GUYS!"  Especially those I understand that are hidden and initiated upon opening.

                       

                      Today of these I can see -- I edit/remove ---I see Acrobat has a fuction to "confirm" such links are valid links and disable non-vailid links,,,,

                       

                      I would like to know if "Acrobate" has a function to "DISABLE or REMOVE"  all links in PDF [displayed or hidden from view].

                        I politly responded to your question --- You are now being silly and not being helpful - and adding to confusion as tro the very specific question.

                         

                        The question is  "Using an Adobe Acrobat program function - how can I "REMOVE & DISABLE" ALL [100%] of user noted, embedded, or hidden web/internet addresses/sites in a PDF? What is Adobe's solution?"

                         

                        Whay are you being so upset about JAVA? That is not the Question?

                          I have no idea to what you're replying to anymore, but I'll do my best...

                           

                          Links can be removed using a script written in JavaScript, and probably also with a Preflight profile.

                          Acrobat/Reader automatically generates links from web addresses, which you can disable at: Edit - Prefs. - General - Create links from URLs.

                            Hello try67,

                             

                            Sorry, for not using your name in my past specific responses. Base upon other commo stings with you  --- I don't know [can't tell] if you're now trying to be honet and/or helpful with me and/or still playing JAVA games...

                             

                            1.  As I mentioned - I am aware of such fuctions of such as creat links from URLs... Which I have created and edit [known] links. Even editing text will accomplish the same for known links.

                             

                            2.  Sadly this is not the solution I was wishing for.... As you are aware - I had hope Acrobat would have a "Function" that would remove/disable "ALL" links/adresses. Such as to the opisit fuctions which Acrobat "confirms" valid connections in the PDF OPTIMIZER FUCTION.

                             

                            If you are not play the JAVA games I wish to thank you for your try...

                             

                            Always remember, everyone is not as smart as you think of yourself.

                              OK, it seems like you'll have to continue your search for answers without

                              my help, then...
