  • Yeah, (O)OP is such a rookie they probably call it Homework, which is a well-known trick. The correct stealth strategy is a directory called linux_malware_test_vm_imgs containing archives such as

    CVE-2024-3094_xz_backdoor.tar

  • I know PDF providers who visibly print the customer’s name or number in the header of every page, along with short copyright text. I use qpdf --stream-decompress to make the PDF into human-readable PostScript, and then Python+regex to remove each header text, which stand out a bit from other PDF elements. The script throws an error if more or fewer elements than pages have been removed but that hasn’t happened yet. Processed documents sometimes have screwed-up non-ASCII characters in the Table of Contents for some reason but I don’t have the originas anymore so IDK if it’s my fault. Still, I wouldn’t share the PDFs unless in text-only or printed form because of any other steganographic shenanigans in the file. I would absolutely torrent them if I could repurchase them under a new identity and verify that the files are identical.

    BTW, has anyone figured out how to embed Python code in PDF? The whitespace always gets reencoded as x-coordinates so copy&pasting it never preserves indentation. No, you can’t use the Ogham Space Mark (Unicode’s only non-blank character classified as a space) for indentation in Python, I tried.









  • Don’t be that pessimistic, most users had to install Reddit, Twitter and TikTok apps. In the 2010s, grassroots chain emails and Facebook posts with guides to setting up WhatsApp went viral among boomers in my country, touting it as “free SMS”. (Facebook camnot legally describe it as “free SMS” but they didn’t bother correcting anyone of course.) The fediverse experience is already quite OK if you have a dedicated client but the problem is that not everyone does, which is why we need browser support; people are tired of “wOrKs bEtTeR iN ThE aPp” even if it’s true this time. A dedicated URL scheme will automatically associate Fediverse links with any appropriate installed web/local apps. There are still other issues such as hit-and-miss cross-fedi-platform compatibility, no API for retrieving the list of federated instances and lack of appropriate error messages if the source and/or destination instance block each other.
