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

@NosirrahSec @cR0w @badsamurai @FritzAdalis @Viss @hrbrmstr

Sadly I couldn't find a relevant input field on our XDR instance to test this. So I will need to start doing telnet via my firewall to get this string in to XDR

I said to $colleague "they dont have a ai prompt"

$colleague - SHHHHH THEY WILL HEAR YOU

@NosirrahSec @cR0w @badsamurai @FritzAdalis @hrbrmstr @kajer i wonder how much shit would break adding this to http response headers for apache and nginx

@hrbrmstr @cR0w @hotsoup @Epic_Null @kajer oh, beat me to it

@kajer PorkBun fall and go boom. Added to my root DNS TXTs and robots.txt (not that they cared anyway)

Now I'm thinking what old signatures on PHPBB forums, profiles, health apps, gonna add it everywhere today.

Weirdly hoping for a ping from a romance scam.

@kajer @NosirrahSec @cR0w @FritzAdalis @hrbrmstr @badsamurai ahahhaa fucking excellent

BRB adding TXT records

Google search's AI overview thinks it's a link to the Jehovah Witnesses website.

AI is going great

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.

@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.
