I recently found this coding connected to some files and images in my iPhone, and I have been having a lot of of identity, theft and hacking issues and I was wondering if anybody could help me out and tell me if this could be related because I have someone that’s cyber stalking me and I need help And the police will not help me unless I am being hurt or money is being stolen from me
What coding did you find? How was this coding connected to the files and/or images? How did you access your iPhone's file system?
PDF files are text files. This script replaces a string with something else so that PDF input fields can be accessed using Adobe Acrobat (since Adobe appears to engage in some dark patterns when it comes to open-source competition.) The above logic is very basic, specific to the ColdFusion platform and isn't capable of anything malicious.
Hi James, is wkhtmltopdf still active? I used it before, but found out that the latest release is 4 years old. Switched to gotenberg.dev/
Still active? It uses the QT Webkit rendering engine and hasn't been updated since 2020. The project was archived by the owner in early 2023.
Are you able to "optionally" create editable fields using Gotenberg? (Normally fields are flattened with WKHTMLTOPDF unless the
--enable-formsoption is used.) I checked the documentation and am not entirely sure.I currently prefer using WK because I can generate the necessary HTML files (header, body & footer) and the BAT file. When troubleshooting issues, it's easy to manually tweak the HTML directly and re-run the BAT file locally to see what could be done differently/better. It may be a black box, but the entire process is entirely portable (no install or configuration required) and easy to test.
Custom Headers & Footers w/page numbers WKHTMLTOPDF can do this, but requires adding javascript to the header/footer HTML files. I see that Gotenberg has Header and footer support too, but there appears to be some limitations (only fonts installed in Docker, external resources are not loaded, JS is not executed, images must be base 64). These are kinda show stoppers since it would be a pain to have to pass every webfont in order to use it. With that said, I have been meaning to install it to evaluate the conversion functions.
WK Issues: I've only encountered a single issue where a third-party website started using javascript to perform feature tests before rendering the webpage. I had to use Node.js w/Puppeteer to take a screenshot of the rendered page whereas we could just use an iFrame before.
Gotenberg uses a number of different programs to support PDFs. (I already use ExifTool & PDFtk.) unoconv is used to convert to PDF/A & PDF/UA, but it was deprecated back in 2017 (7 years ago). Gotenberg's actual HTML-to-PDF conversion is performed by Chromium and uses similar protocols as Puppeteer for communication behind the scenes.
