      A perspective from someone who red teams for a living:

      If I encounter a password like that, I’m probably going to pay special attention to your account among the millions. Commas dont stop most people from being weak to password permutations either.

        If you’re manually checking the 12 million username password pairs in the leaked database you aren’t really going to breach many accounts before people update their passwords, are you?

          I’m referring to when it breaks my tooling and I’m forced to dig into the problem.

          That being said, thats not really a problem for modern tools like credmaster.

      intermix the , and the ; as well, in case the CSV uses a different separator.

      I think Python csv would save that as "Pass\",\"words\",\"Are\",\"fun\",\"\\n" and then it would be read by Excel / LibreOffice / Python csv as expected.

    OP thinks security researchers don’t understand how to properly serialize data for correct deserialization. OP also thinks they largely use CSV.

      CSV existed for over 30 years before RFC 4180. Excel, and countless other tools, have their own incompatible variants. Excel in particular is infamous for mangling separators when exporting to CSV.

        Fuck Excel’s CSV handing. It differs by locale, silently. Imagine the thousands of people every year who patiently wait to import a multi-megabyte CSV from some instrument only to see garbage because their language uses the decimal comma and semicolon separator.

        Excel mangles everthing…
        I work with a lot of EANs and every CSV import into Excel means I have to pay extra attention to the EAN field, because Excel likes to think for me, and thinks that the scientific notation would be very helpful for me… It’s not! 8.72E+12 is useless to me, Excel!!!
        And don’t get me started on FEB-01.

        I just fuckin’ hate Excel.

      yeah unless you’re dealing with some steaming pile of vibe-coded shit this is a dumb as fuck idea.

      (have seen people who don’t know how to appropriately use an LLM just let it wholly reimplement standards, read it over, and then say “oh wow that works great!” smh…)

          of course there’s always been terrible code. people used to and still do reinvent the wheel all the time, even without the help of a robot.

          trust me i’m one of the last people to shit on LLMs unnecessarily. the tools coming out nowadays are the bees knees. i think vibe coding is fucking awesome and most people’s premonitions against it are things that, similar to the premise, have just always been true - most of the “evil” of vibe coding can be dealt with easily by being a not shit engineer in the first place.

          plus, not every problem needs to be a software development problem through and through. sometimes you just need a webui or an api to browse a dataset, for example - it’s not opsec critical and you need it now. that’s okay. the moral police won’t come to your house and arrest you for vibe coding.

      You would be surprised how many people are simply splitting the string on commas instead of using an actual ascii parser. Especially for one off scripts, like churning through a csv full of passwords.

        Should work alright if the server handles Unicode correctly, and isn’t one of those ass sites that put restrictions on the password’s length and composition. Hashing functions don’t even care if you’re feeding them raw binary.

          I… I hope my passwords are hashed and salted long before they reach the server, so the way it handles unicode shouldn’t affect it all that much. The logistical issue I was seeing with emojis was more that some of them look the same but have different Unicodes alltogether, so typing in the same emoji across devices might be tricky if their keyboards default to different codes.

            Oooh hashed and SALTED! I kept peppering the passwords that get sent to my server. Now all I need is to clean up the mess and the mold that all those hash browns leave behind.

            Passwords are typically sent to the server and hashed there. I’m a bit hazy right now on the implications of client-side hashing, but it would likely present some security problems.

            Edit: at the least, it would allow an attacker to use a leaked password database to log in to the sites, sidestepping the whole hashing thing.

            There are protocols that send a hashed or encrypted password instead of plaintext, but they’re more complex than just hashing. Iirc they involve a challenge-and-response method.

    I don’t think they actually store any passwords, usually hashes are stored for better security. Of course not everyone does this so yeah thanks to Skeleton.

    Correct me if I’m wrong, but doesn’t text with commas in it get put in double quotes in acsv file to avoid this exact thing?

    Like if I had cells (1A: this contains no comma), (2B: this, contains a comma), and (3C: end of line), the csv file would store (this contains no comma,“this, contains a comma”,end of line)

      Yes and no. Like yes, that can be true. But a lot of tools don’t handle commas correctly no matter how you escape them.

      A CSV is just a long string of text with a few control characters tossed in for end lines. There are practically no rules enforced by the file type itself. You can dump that unsanitized and poorly awk’d data into whatever awful mess you want. Nobody’s stopping you. Sure, excel will force it’s CSV formatting rules on you when you export like a child’s training wheels. But that’s not relevant here.
