    Use EICAR test strings as passwords so when the password is stored as plain text the antivirus software will delete the file.

        Doesn’t have to be a binary file, toss the string in a txt file and the AV still throws a fit.

      Sadly it wouldn’t work if found in a CSV file with other records:

      According to EICAR’s specification the antivirus detects the test file only if it starts with the 68-byte test string and is not more than 128 bytes long. As a result, antiviruses are not expected to raise an alarm on some other document containing the test string

      Unfortunately there is significant overlap between plain-text-password-servers and servers that can’t be bothered to use antivirus. Also, the string may not work if it’s not at the start of the file. AV often doesn’t process the whole file for efficiency purposes.

        It’s not about the password on the server where you want to log in, it’s about CSV files stored on the machine of the cybercrook who wants to use the passwords to steal people’s identities.

      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.

      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.

              Different languages have different rules for making words plural. Dutch, for instance, requires an apostrophe for a lot of them. (een komma, twee komma’s), so a mistake is quickly made.

              To err is human, still… Are you able to type 100% faultlessly in your second or third language?

      An apostrophe might have an even better effect than a comma. PSA: Don’t shoot yourself in the foot by escaping commas or apostrophes! Like in password:“,\,',\‘’!DROP TABLE(''users')” That’s more likely to “trick” the log on machine that to bust a CSV file.

        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.

            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.

      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.

        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!!!

        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.

          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.
