Earlier this week, Dario
0:01
and the Anthropic team pulled the ultimate trust me bro power move
0:05
when they announced Mythos,
0:06
a model so powerful, so capable,
0:08
so veiny that they claim the fallout for economies, public safety,
0:12
and national security could be severe
0:14
if it were to be released to the general public.
0:17
And as you can imagine, this has everyone losing their collective minds again.
0:20
>> Something very familiar about all this.
0:23
>> Some are saying Mythos may lead to the entire cybersecurity industry collapsing under
0:27
the weight of our new god in a box.
0:29
>> Because the security implications of a model that is this capable are terrifying.
0:34
>> While others are saying Anthropic is just repeating the same model release playbook
0:38
we've seen countless times before to scare the slop out of people,
0:41
then quietly release a model
0:43
that can't even code a spell five to do app.
0:45
For us in our parasocial relationship, it's like a fun game of Russian roulette,
0:49
but instead of getting shot in the head,
0:51
you have to become a ranch hand
0:52
and I have to start teaching tutorials on how to collect turkey semen
0:55
so you can deploy genetic payloads into production hens.
0:58
In today's video, we'll break down Mythos
1:00
and I'll show you my bulletproof guide on how to update your software fast
1:04
enough that you not get zero dayed,
1:05
but slow enough to not get supply chain attacked.
1:08
It is April 10th, 2026 and you're watching The Code Report.
1:11
I'm tired, boss, because every time a new model comes out,
1:14
it seems to bring on a new form of mass psychosis.
1:17
Midjourney was going to make all human art obsolete,
1:20
but now nobody talks about it.
1:21
GPT-4o had an entire subreddit feeling love for the first time.
1:25
And now Mythos, without even being publicly available,
1:28
has many feeling existential dread for the first time.
1:31
And the reason for that feeling is that during Anthropic's internal testing,
1:35
they discovered that Mythos is basically a zero-day vending machine.
1:38
It found a 16-year-old vulnerability in FFmpeg,
1:42
which allowed an attacker to craft a malicious video file
1:45
that tricks the decoder into writing a few bytes of data outside its allowed
1:48
memory,
1:49
potentially crashing the program and corrupting nearby data.
1:52
It was also able to find a 27-year-old bug in OpenBSD,
1:56
allowing a remote attacker to trigger a null pointer write,
1:59
which instantly crashes any OpenBSD machine reachable over TCP.
2:03
In every major browser,
2:05
it was able to run a train on a few JavaScript engine bugs
2:07
that lets a malicious webpage escape the browser sandbox.
2:10
In one case, that allowed it to steal data across websites, and in another,
2:14
it was able to write directly to the operating system's kernel,
2:17
giving an attacker full control over the device the moment the victim opened the
2:21
webpage.
2:22
And my personal favorite,
2:23
it found a bug in the Linux kernel
2:25
which let it flip a single bit in a neighboring memory page,
2:28
which turned the password executable into a writable file,
2:31
which it then overwrote to gain full root access to the system.
2:34
>> I found more bugs in the last couple of weeks than I found
2:37
in the rest of my life combined.
2:38
>> And just yesterday, US Treasury Secretary Scott Bessent
2:42
and Federal Reserve Chair Jerome Money Printer Powell has set up an urgent meeting
2:46
with bank CEOs to warn of the security dangers posed by Mythos.
2:50
So, it's no wonder
2:51
that Dario is pulling inspiration from House Harkonnen
2:54
and locking down control of the spice with the announcement of Project Glasswing,
2:58
a new initiative that brings together a collection of companies
3:01
that happen to pay Anthropic a lot of money in an effort to secure
3:04
the world's most critical software via access to Mythos.
3:08
The idea is that Mythos is too dangerous for a default config NPC like
3:12
you to have,
3:13
but perfectly safe in the hands of a dozen trillion-dollar companies
3:16
and a bank.
3:17
Anthropic's plan is that the fellowship will quickly patch all of the world's software
3:21
before anyone else builds a model this capable,
3:23
which, if it's up to Sinister Sam,
3:25
now that Open AI is no longer acting
3:27
as the fluffer of slop gen AI videos,
3:29
will hopefully be any day now.
3:31
But, not everyone is convinced that Mythos is that capable.
3:34
Anthropic has been using Mythos internally since February 24th, and since then,
3:38
they leaked Claude code source code, leaked documents revealing the existence of Mythos,
3:43
and have had a very rough time even keeping their APIs online.
3:46
On top of that,
3:47
the way Mythos actually found these exploits is a little sus.
3:50
Like, the OpenBSD vulnerability came out of 1000 parallel agent runs across the code
3:55
base at costing nearly $20,000 in compute.
3:58
If you use the same process with Opus 4.6
4:00
or GPT 5.4 Pro,
4:02
you'd probably find plenty of issues as well.
4:05
And the Firefox numbers are doing something similar.
4:07
One of the claims is
4:08
that Mythos had an 84% success rate at writing working exploits in Firefox,
4:13
which is a massive jump over Opus 4.6's 15%.
4:17
But that number isn't against actual Firefox.
4:19
It's against a SpiderMonkey shell with the process sand box
4:23
and other mitigations turned off.
4:24
So that begs the question, is Mythos going to destroy the world?
4:28
Well, in my expert opinion, it almost certainly will not.
4:30
But is Mythos a real step up from Anthropic's current flagship model Opus 4.6?
4:35
Probably yes.
4:36
Either way, we'll just have to take their word for it
4:39
because >> It's a big club
4:41
and you ain't in it.
4:42
>> But if you want to try an amazing tool
4:44
that you can actually use today,
4:45
you should check out BrowserBase, the sponsor of today's video.
4:48
It's a complete platform for building
4:50
and deploying browser agents where a single API key it gives your agent access
4:55
to cloud browsers,
4:56
web search, and everything else it needs to access the web like a real
5:00
human being.
5:01
This lets your agents perform more complex jobs like filling out forms
5:05
and extracting unstructured data.
5:07
And it's built in tandem with StageHand,
5:09
their popular open-source SDK for browser agents.
5:12
They also partnered with Cloudflare on an open-source protocol called WebBot Auth,
5:17
which lets your agents prove they're legit
5:19
so they can access any website without pretending to be human.
5:22
Teams at Microsoft, Lovable, Ramp,
5:25
and many others are already using it to build thousands of browser agents.
5:28
And you can try it out for free using the link below.
5:31
This has been the Code Report.
5:32
Thanks for watching and I will see you in the next one.
