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

[–] Orygin@sh.itjust.works 19 points 15 hours ago (1 children)

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

[–] Valmond@lemmy.world 118 points 21 hours ago (2 children)

Dude makes a whole binary of a virus his password.

[–] slazer2au@lemmy.world 61 points 21 hours ago (1 children)

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

[–] sem@lemmy.blahaj.zone 5 points 9 hours ago

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?

[–] Strider@lemmy.world 60 points 21 hours ago (1 children)
[–] CaptainBlagbird@lemmy.world 67 points 21 hours ago (2 children)

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.

[–] tomiant@piefed.social 4 points 15 hours ago

I am really liking this place.

A specific string of text that you can use to test your AV without actually grabbing a virus.

[–] henfredemars 22 points 20 hours ago (1 children)

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.

[–] b_tr3e@feddit.org 45 points 20 hours ago

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.

[–] 30p87@feddit.org 3 points 14 hours ago

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.

Unless you're the only one in the dump, no :c

[–] Saganaki@lemmy.zip 9 points 21 hours ago

unfortunately, nearly all AV abides by the “cannot be larger than 68 bytes” rule
