With the and the attacker's system hosting the Empire listener, the malicious AppleScript can be created and disguised to appear as a legitimate PDF using a few Unicode and icon manipulation tricks. A real PDF is required for this attack to work. Files over 1 MB in size would be too large and may cause the target to become suspicious. The real PDF will be downloaded every time the target opens the Trojanized AppleScript (the fake PDF), so the real PDF should be only one page and small enough to download quickly, otherwise, the target might start wondering why it takes a few seconds for the PDF to load in Preview when it should be instantaneous. Previously: In this follow-up to the, I'll show how to quickly create a PDF using the cover of a CompTIA study guide found on, but a higher quality image should be used during a real scenario. Step 1: Copy a PDF Cover Image In your web browser, navigate to a site that has the PDF that's going to be cloned. In my example, that's the on AllITebooks. ![]() Moving from the Script Editor to the Comic Editor Now that you have finished typing your script using Keywords you can click on the “Start Comic” icon in the toolbar. This will present you with the template chooser again. If you’re not using this script, just make a new script for your entries. It’s quite simple: type two colons, followed by the hotkey text. After two more colons, type the phrase to be expanded. You don't actually need to download the PDF file, you just need the first image that appears in the preview, so right-click on that, select 'Save Image As,' then 'Save' it with the name cover.jpg into the files/ directory. Step 2: Install GIMP & Open the Image In order to manipulate the PDF's cover image, we'll need GIMP, a popular image-manipulation application that's totally free. To install it, use the command below. Apt-get install gimp Once installed, open cover.jpg in GIMP with the below command. Gimp cover.jpg Step 3: Export the Cover Image as a PDF Next, export the image to the files/ directory by navigating to 'File,' then 'Export As.' Change the file name to real.pdf and file type to 'Portable Document Format (*.pdf).' When the conversion is finished, download and save the.icns file to the files/ directory. There should now be four files in the files/ directory (you can check with ). Quicktime movie editor for windows. How To Make A Auto Clicker For Mac Using Script Editor In Chief`/ tokyoneon ~/files > ls cover.icns cover.jpg cover.png real.pdf The cover.jpg and cover.png were used as templates and are no longer required. The real.pdf is a small PDF that will be downloaded by the target every time the AppleScript (the fake PDF) is opened. The cover.icns is the Apple icon file which will be used in a later step. That's it for the Kali Linux end of things. To create the malicious AppleScript (fake PDF), I'll be using in macOS High Sierra. Step 8: Create the AppleScript It should be possible to create trojanized AppleScripts using Kali, but it's a bit more involved than this article allows for. To keep things simple, I'll use macOS with AppleScript version 2.7 and Script Editor version 2.10.
