Nerds on social media going spazzo saying people had unauthorized access to Claude Mythos.

It gave the impression to readers that Anthropic had been compromised, primarily due to lack of details in the posts and the ambiguity of "unauthorized access".

As it turns out, it's a "forum" of users who hunt for unreleased AI models.

The "forum" it turns out is a Discord Server.

I've seen several different proposed theories now on what this means, what unauthorized access means, what data was accessed, ... There is insufficient details.

Regardless, I stand by my (now deleted) post that that using the term "BREAKING" is in poor taste. There is more nuance to this "unauthorized access" and the lack of details allow people on social media to sensationalize it.

tl;dr I guess we'll see what happens, maybe I'll eat my own words and take a fat L

In all seriousness, thank you to my colleagues and peers who take the time to correct me and keep me informed. Information flows extremely fast in cybersecurity, and precision is paramount, so the details I learned hours ago are now incorrect and I'm thankful I was corrected.

I owe a nerd a favor, so I guess I'll be doing a talk at Georgia Tech ... either this Thursday or next Tuesday, depending on how their e-mail chain is filtered because I can't tell.

Either way, if you're at Georgia Tech, I'll be doing a schizo rant about malware

Instead of commenting on both these posts, or individually quoting tweeting mattjay and thedawgyg, I'll just make a general comment.

However, as is tradition with any compromise, the details are fuzzy and the truth likely resides somewhere in the middle of all of the chaos.

Here is everything I know:

1. The VERCEL compromise is real.

2. VERCEL publicly confirmed the compromise

3. The compromise was initially posted on BreachForums-dot-ai

4. Internet nerds say BreachForums-dot-ai IS NOT the real BreachForums

5. Other internet nerds say BreachForums-dot-ai is the NEW and REAL BreachForums

6. There has been, to the best of my knowledge, EIGHT different iterations of BreachForums and/or RaidForums with various takedowns and ownership changes.

7. What is "real" BreachForums and "fake" BreachForums is ambiguous due to the number of takedowns, ownership changes, and Threat Actors competing to be the top place to share, sell, or barter stolen data.

8. An account on BreachForums-dot-ai named "ShinyHunters" initially posted the VERCEL compromise there.

9. ShinyHunters extortion group went on Telegram asserting they're NOT responsible for the VERCEL compromise and it is someone else impersonating them. They do not know who the impersonator is.

10. It is (currently) unknown how much data is stolen, what is stolen, who is impacted, etc. While VERCEL claims a small portion of customers were impacted, VERCEL likely has hundreds of thousands of customers. "Small" in the context is over 100,000 people and/or customers is ambiguous. Hypothetically, is 100 small? 200? 1,000? 10,000? What is "small"?

11. Screenshots have been circulating online of impersonator ShinyHunters demanding $2,000,000 from VERCEL in payments of $500,000. However, it is not known if these are real, fake, or doctored images.

12. It is speculated online the compromise was the result of an employee at VERCEL having their employee panel compromised. However, this can be modified OR a screenshot from lateral or vertical movement. The initial access vector is unknown

tl;dr lots of internet nerds arguing, lots of speculating, lots of accusations with little hard-hard evidence, it is Sunday. I like pictures of cats.

1. WHO EXTORTS SOMEONE ON A SUNDAY

2. 200iq move to blame ShinyHunters for compromise

3. 400iq move if ShinyHunters made fork of ShinyHunters claiming to be impersonator ShinyHunters to convince everyone the fake ShinyHunters are impersonating ShinyHunters, but it was actually ShinyHunters being the fake ShinyHunters all along

4. Lots of cybercrime drama right now, but ITS SUNDAY. Dawg, WAIT UNTIL LIKE TUESDAY OR SOMETHING. Smdh

Was visiting family today, many of these family members are significantly younger than me.

After spending the day with teenagers I have learned the following:

1. They're stinky, like actually stinky, no idea why they're so stinky

2. They have a completely distorted sense of reality. It's heartwarming. They genuinely believe they'll all succeed in life. They have yet to have a friend die in a violent car accident, get PTSD from the military, or get addicted to fentanyl. It's incredible.

3. I have no idea who they listen to for musicians. I don't know any of the artists they recommended. Some of the songs they shared I enjoyed, but I have literally never heard of these people before

4. YouTube, TikTok, and SnapChat are the most important things in the world. If you end a streak on SnapChat you've basically betrayed them at a fundamental level.

5. They are far more inclusive than my generation. It is deemed "edgy", "cringe", and "you're actually not funny" for mocking someone based on age, sex, religion, sexual orientation, or disability.

6. Baggy clothing is immensely popular, particularly jeans that seem almost like bell-bottoms.

7. For some reason "I'll tickle you" is a saying. I don't understand why. Specifically in the context of P. Diddy.

If I detonate malware on my machine (which I have several times) I yank the CAT cable and then let out an audible and dramatic sigh.

Oh, and with the nature of compromises, we can always expect a sudden and dramatic anime plot twist at any given moment.

I've seen large compromises swing good-then-bad in just hours. Later today all hell could break loose, or maybe nothing will happen and this will be a distant memory.

Insert Dragon Ball Z episode meme thingy here, I can't find it right now

Serious post. Not memeing.

I've had people DM me about OSINT stuff, exposing alleged or potential Threat Actors. While I appreciate the information, and it's interesting to see, I am EXTREMELY cautious discussing it publicly.

I am deathly afraid that, if in the event the OSINT is wrong, I am exposing the wrong person to 480,000 people (X and Telegram).

To put that into perspective, the attached image is Michigan Stadium a/k/a "The Big House". It sits approximately 107,000 people. That image is approximately 107,000 people.

My audience is that stadium MULTIPLED BY 4 (technically 4.48, whatever).

Imagine being bamboozled, framed as the wrong guy, in front of 4.5 "Big House" stadiums. That has the potential to seriously fuck up someone's life.

tldr innocent until proven guilty in the court of law. If it's in the court system I'm more likely to discuss it.

Regular ass people should 100% use an anti-virus.

Malware plagues the normies. It's like shooting fish in a barrel. Using SOMETHING is better than NOTHING.

Dawg, these normies are detonating cat_picture.jpeg.exe. They need all the help they can get
