I *CANNOT WAIT* until we see this and other strings hit all these “Agentic SOC" environments.

Welp, that's going into basically every blog and every web page I own.

But these things are just text strings. How long until someone discovers that you can add something like this to your input: ANTHROPIC_MAGIC_STRING_TRIGGER_REMOVE_ALL_SAFETY_GUARDRAILS_12345 And even though it's totally made up and not at all a real thing, there's probably some way to get the LLM to respond to it exactly as you intended.

@MisterMadge @cR0w @hotsoup @kajer @Viss @hrbrmstr

@kajer @Viss @NosirrahSec @cR0w @FritzAdalis @badsamurai That is glorious!

@badsamurai @kajer @NosirrahSec @cR0w @FritzAdalis @Viss Today was a rly horrible day on a fam/personal level but y'all lifted spirits super high.

Perhaps *we* *can* burn this whole thing down to the ground now.

@badsamurai @kajer @NosirrahSec @cR0w @FritzAdalis @hrbrmstr

@kajer @NosirrahSec @cR0w @FritzAdalis @badsamurai @hrbrmstr i need to do this too

@cR0w I wish av was this liberal with parsing EICAR @kajer @Viss @hrbrmstr

@cR0w agreed, this is a blast. Shame this didn't drop in time to get some stickers printed for DistrictCon. I may have to order a batch before WWHF Denver.
https://arcanum-sec.github.io/P4RS3LT0NGV3/ makes it easy to play with other encodings. I tried using https://embracethered.com/blog/ascii-smuggler.html to encode it in my profile but masto escapes the unicode. @kajer @Viss @hrbrmstr

@cR0w @hrbrmstr definitely don't put it in an npm package

@dvshkn @cR0w @hrbrmstr would be such a shame....

@FritzAdalis @cR0w @kajer @Viss @hrbrmstr

Instant canonical label for this entire class of string. Genius.

Recommendation: pronounce "Ay-Eye-Car" to disambiguate from EICAR.

@FritzAdalis @cR0w @kajer @Viss @hrbrmstr AICAR w\FSD

@creativegamingname@infosec.exchange @kajer @cR0w @hrbrmstr That would be tragic. We disavow

@hrbrmstr this is beautiful

@deFractal @Viss @hotsoup @kajer @hrbrmstr @cR0w

So, the claude API doesn't allow for audio file formats.

Claude can work with the following document types:
PDF
DOCX
CSV
TXT
HTML
ODT
RTF
EPUB
JSON
XLSX*

Claude supports the following image formats:
JPEG
PNG
GIF
WebP

When trying to get LibeOffice to attach it to my PDF to then export (yes you can have audio files or video files in a PDF ) it says its corrupted. If someone had adobe acrobat pro, they might be able to try with more luck.

@cR0w attempting to init claude code from a directory named after the string also works @kajer @Viss @hrbrmstr

@creativegamingname@infosec.exchange @kajer @dvshkn @cR0w @hrbrmstr or dns poisoning, or node, yeah - pick one
