THE INTERNET IS FOR EVERYONE
First of all, wishing all readers Selamat Hari Raya!
A question. How do you transmit PDF documents to your customers/ vendors/ all other people? If you think that sending a PDF is better than sending a doc, you've got it all wrong... Let's see why... But before we get into how we can hack PDF documents, let's look at the evolution of the PDF documents:
Some time ago, DOC files used to move around as attachments in mails and people used them without worries. If the documents had to be confidential and private, they would be marked so in the header or footer or as a water-mark, and that was it.
But it soon so happened that untrusted and changed documents also started the mention of confidential and private, which meant this became a trust issue. Anyone on the network could get hold of your document, edit the content and send it forward and you wouldn't know if this came from a trusted source. (unless you go to Properties, check out the creation and last modified dates, in which case, you still dont know whether it was modified officially!)
Then everyone started using the Adobe format (PDF). You could take any document, convert it into PDF for which you had to buy tools like Distiller etc, and send these documents. This worked well for some time, people also came up with open source versions of PDF converters and, in fact all MS Office tools started providing the PDF converter plugin. But later, it was realized that a hacker still can copy and paste from the PDF onto a DOC, change the content and create a PDF out of it. So the trust issue seemed to be still hovering.
The next version for handling this trust issue came in the form of scanned PDF documents, which is a pretty good idea. After you create a document, take a print of it, get the signatures on it (if needed), then scan and send the PDF to the recipients. Copying the text from a scanned document (PDF) is not easy. This has thus far been "kind of" the best way to transmit documents.
But it's possible to hack this also. What you need for this hack are:
1. Google drive account
2. The PDF you want to hack
3. Some patience :o)
So let's get started...
1. First, upload ANY document to Google drive (can be any document format, jpg, png, doc, pdf anything), and ensure that you use the web (dont use the Google Drive app).
2. While uploading the document, there is a status bar shown by Google.
3. On this you'll see a small settings icon. Click on it and select the option "Convert Uploaded files to Google Docs format".
4. What you've done is turned on optical character recognition (OCR). Now you are ready to upload the PDF.
5. Now you are ready to upload your scanned PDF file.
6. Once done, open it from within the Google Docs web UI, and you'll be able to copy each character, or word, or sentence or the entire PDF file into the clipboard!!
7. Please note that only the text is copied, not the format.
8. Also if the language is different from the ones available in https://translate.google.com translation-availability list, the OCR will not work.
Also please use this for ethical use only...
Have a Wonderful Holiday
Can we hack you before the hackers do?
