      Inversely, it’s also amazing what a lack thereof cannot achieve, for instance, redacting publicized documents.

    …it’s safe to say that Pam Bondi’s DoJ did not put its best and brightest on this (admittedly gargantuan) undertaking

    Actually they did. It’s just that their best and brightest are fairly dim.

      Long story short:

      • Some of the emails in the file dump had attachments.
      • The way attachments work in emails is that they’re converted to encoded text.
      • That encoded text was included - badly - in the file dump.
      • So it’s theoretically possible to convert them back to the original files, but it will take work to get the text back. Every character has to be exactly correct.

      Source: I’m a software developer and I’m currently trying to recover one of these attachments.

        Are you having as much trouble with OCR as the article author? I would have thought OCR was a solved problem in 2026 even with poor font selection.

          I wonder if they gave considered crowdsourcing this, having many people type in small chunks of the data by hand, doing their own character recognition? Get enough people in and enough overlap and the process would have some built-in error correction.

          OCR is mostly good enough. Problem here is we have 76 pages that we need to be read perfectly, with a low fidelity input

          We also have very little in the way of error correction, since it’s mostly not human readable

            We also have very little in the way of error correction, since it’s mostly not human readable

            This is the main point.
            Most well working OCR systems have a dictionary-check pass, which goes a long way into fixing the errors.

            On the other hand, if all those files are the same font and size, it should be possible to tune the OCR to better match the requirements. Also reduce the possibilities to the character set used by the encoding.


            I was recently using OCR for an unrelated project and it was totally unusable as is, because unlike what it expected (plain text documents), it got text on top of pictures. So now I have to find ways to preprocess and single out the text, removing the graphic lines that might be behind it, to make it readable.

        Curious here, this is base 64? And what’s behind it is more often than not an image or text? And you need to do ocr to get the characters?

        Maybe for the text it could use a dictionary to rubber stamp whether that zero is actually a letter oh, etc etc?

        I’m curious to know what the challenge is and what your approach is.

          Yes, it’s base64. And what’s behind it could be anything that can be attached to an email.

          In this case, it’s a PDF. If the base64 text can be extracted accurately, then the PDF that was attached to the email can be recreated.

          The challenge is basically twofold:

          1. There’s a lot of text, and it needs to be extracted perfectly. Even one character being wrong corrupts it and makes it impossible to decode.
          2. As the article points out, there are lots of visual problems with the encoded text, including the shitty font it’s displayed with, which makes automating the extraction damn near impossible. OCR is very good these days, but this is kind of a perfect example of text that it has trouble with.

          As for my approach, I’m basically just slowly and painstakingly running several OCR tools on small bits at a time, merging the resulting outputs, and doing my best to correct mistakes manually.

      There’s an iOS game about the history of fonts you might enjoy. Struggling to find it at the moment, but you play a colon navigating through time, solving various puzzles.

      Some of the reactions are some in an effective way, and I assume this example is one of them. The problem being evidently they didn’t think any what might be in big base64 blobs in the PDF, and I guess some of these folks somehow had their email encoded as PDF, which seems bonkers…

    I tried to leave a comment, but it doesn’t seem to be showing up there.

    I’ll just leave it here:

    too tired to look into this, one suggestion though - since the hangup seems to be comparing an L and a 1, maybe you need to get into per-pixel measurements. This might be necessary if the effectiveness of ML or OCR models isn’t at least 99.5% for a document containing thousands of ambiguous L’s. Any inaccuracies from an ML or OCR model will leave you guessing 2^N candidates which becomes infeasible quickly. Maybe reverse engineering the font rendering by creating an exact replica of the source image? I trust some talented hacker will nail this in no time.

    i also support the idea to check for pdf errors using a stream decoder.

        Since there’s 78 pages, I’m guessing at least 1 ambiguity per page? Anyways, it’s dreadfully big.

          2^78 is large but computers can do an awful lot per second, so if only about some the pages contain attachments 2^40-55 is something you could bruteforce in weeks if you can do millions of attempts a second
