Use EICAR test strings as passwords so when the password is stored as plain text the antivirus software will delete the file.
Dude makes a whole binary of a virus his password.
Doesn’t have to be a binary file, toss the string in a txt file and the AV still throws a fit.
According to wikipedia it has to be at the beginning of the test file or it won’t work.

What is an EICAR test string?
a computer file that was developed by the European Institute for Computer Antivirus Research (EICAR) and Computer Antivirus Research Organization to test the response of computer antivirus programs. Instead of using real malware, which could cause real damage, this test file allows people to test anti-virus software without having to use real malware.

A specific string of text that you can use to test your AV without actually grabbing a virus.
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
They actually thought it through, huh?
For some reason that surprises me from the AV vendors

fun fact, “commas” does not require an apostrophe
Yeah, but look at how many extra comments that generates. I’m starting to think that intentionally bad grammar is sometimes a good social media tactic to create engagement on top of what you’re already doing, but I’m not excluding people being just plain illiterate.
Add apostrophes to “commas” to mess with me

Interesting… I wrote a gag comment about using an SQL injection as my password and crashed the Lemmy API. Using connect if that makes any difference.
Like the Bobby tables? Can u put it in a coffee?
Bobby’, –
SQL injection in the big 2025…
Friend, we’re still seeing publicly exposed plaintext credentials in 2025…
I haven’t kept up with the cybersecurity world recently. Ever since I graduated I’ve just been completely fed up with IT. Is there a story behind this? Has a major service done this lately?
Thanks to my password manager, commas are among the more tame characters that occur in my passwords.
Hm, now you’re making me wonder how feasible it would be to use Emojis in my 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.
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.
Real passwords contain ASCII 0.
CSV has standard escape sequences. This is pointless
See RFC-4180:
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.
That standard won’t stop me because I can’t read!
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.
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.
What about quotes (single/double) and \s mixed with commas?
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.
Gotcha, that’s what I was thinking as well. I haven’t done any software development in a long time (I have a degree in it, but professional career sent me down another path in tech), so my memory on input sanitization is very rusty. Thanks for the response!
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.
That’s why I use “” to escape the commas.
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)
Only if it’s actually using a standard like rfc 4180 https://www.ietf.org/rfc/rfc4180.txt
Also just noticed it specifies CRLF as the line ending, not LF, which is kind of weird.
Why did the creator add an incorrect apostrophe in “commas,” but not “passwords?” At least be consistent!
Mine are typical error messages.
See you next time!
