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

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.

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

22

unfortunately, nearly all AV abides by the β€œcannot be larger than 68 bytes” rule

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.

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.

They had to put a comma in there somewhere. Even of it was in the wrong place and upside down.

Sadly, no. CSV files can deal with embedded commas via quoting or escaping. Given that most of the dumps are going to be put together and consumed via common libraries (e.g.python's csv module), that's all going to happen automagically.

Everything you can use for a password can be escaped out of a csv. Partially because csvs have to be interoperable with databases for a bunch of different reasons, and databases are where your passwords are stored (though ideally not in plaintext). There's no way that I can think of to poison your password for a data breach that wouldn't also poison the password database for the service you're trying to log into.

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

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.

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.

pythonreply
lemmy.world

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.

1

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.

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.

14

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.

Guys calm the fuck down. The point of this joke is not that you’ll be bulletproof a few in sort of a few commas and passwords every now and then. The point is that a lot of these guys use terrible scripts that do not parse data correctly and they dump all of this shit into large CSV files. One or two people put an errand, in there that it doesn’t expect and it fucks the whole thing sideways for the entire set everything after the asshole with the comma password gets fucked. People that know what they’re doing will be just fine with it, but scammers generally don’t know what the fuck they’re doing and they pass this data along over and over and over again it change his hands frequently. So there’s more chances for it to get fucked along the way.

Use a long series of spaces as your password. At least that way they'll have to do a double take when they crack the hash.

Don't forget to add a double quote before the comma. Otherwise it'll just become "ascjk,QRcdosaiw9;drop table users;commit;--"

So instead make your password ascjk",QRcdosaiw9;drop table users;commit;-- or something like it.

Kinda yes, but really no. If they assume there is always a comma, but if you add it after you've generated whatever password you've chosen you're still making it harder for them.

Bit of a joke related to bringing "what is TSV" to an "intense" TSV vs CSV debate.

As for TSV itself, it's a widely used standard from 32 years ago, and is often a default record delimiter when used with GNU/POSIX tools.

It mostly exists as legacy at this point, as people now prefer quoted values like those given in CSV (ver2) and JSON formats.
