there have been a few links here on hn about content protection based on Markov’s chain. It might be interesting for Cloudflare to add damage for the scraper that tries to query the page, and not just blocking them.

New comment by nicolodev in "Show HN: I made a calculator that works over disjoint sets of intervals"

It’s astonishing how nobody hasn’t mentioned abstract interpretation yet. Under classical static analysis, if you can “prove” that a variable does not have values in some unsound zones, you can e.g. “prove” soundness or apply further optimizations.

The interval abstract domain works under interval analysis with an algebra that’s the same of this calculator. It’s funny to implement something like that on source/binary level :)

Another good replacement for capstone/keystone based on LLVM is nyxstone https://github.com/emproof-com/nyxstone

yeah I agree, and while everyone is suggesting tools which are really good but I designed mine to get rid of the flags and CLI interface. Good for tech people that keeps remembering flags, I'm not :(

> mutool clean -d in.pdf out. pdf

My tool can do exactly the same (viewing internal structure, exporting objects, and see the uncompressed raw content for stream) with a graphical interface and without all this kind of flags (which one of the reasons I started to design this project with egui), but thanks for posting yours too.

Thanks! Immediate paradigm might be a little bit scary if you used to play with Qt, but looks easy to manage and it's really interactive

argh, that's too bad, feel free to open an issue, what's happening in the console? It's panicking, isn't it? Feel free to contact me via email if you prefer

Nice! My tool should be runnable in the browser thanks to wasm compatibility with Rust + egui :) Btw I've just tried it, and it's a little bit buggy in Safari with a 504kb PDF (lots of objects though). Apart from that, is there a way to export the raw stream? Is there any reason of do you print all the raw streams as a text?

:D Well, I'm sure that half of reverse engineering community needs to thank you, and Zynamics for the important contribution for tools of static analysis. I just take the occasion to thank you for being an inspiration with such awesome tools like in BinNavi, BinDiff, and ultimately PDF dissector. When I was reading that it got discontinued, I just had that idea and started to reason about something focused on analysis, and applying some approaches we've already seen for the binary analysis tools.

Thanks for the list, the idea behind my tool was to try to code something that might fit an analyst that would take a fast look at the PDF. I'm also trying to figure out some fast heuristics to mark/highlight some peculiar stuff on the file itself.

Now regarding the tools you mentioned, I haven't checked out all of them, but part of them are interesting (and more mature, speaking of testing and compatibility). However some (at least the ones I was trying) are very basic, and they don't allow the "Save object as.." or uncompress it. I like the feature of displaying the PDF for preview :)

I'd suggest you to code something along popular libraries for PDF manipulation. I've used pdf-rs for the tool.

Thanks, it seems a great product too :) Do you have any particular feature that you share that product for?

I’m writing a little tool for analysing a pdf and its internals, if author is interested or anyone else, just let me know :)
