Facebook once bought a VPN app for $120M and turned it into a surveillance tool that spied on 33M+ users' entire phones for years.

This app helped Zuck buy WhatsApp for a whopping $19B and break Snapchat's encryption.

Thread
The name of this Israeli app was Onavo.

It promised to “secure your data” and reduce mobile data usage.

When Facebook bought it in 2013, Zuck said the app would help them connect more people to the internet.

Facebook even promised to keep Onavo running as a standalone brand. Image
But Onavo operated as a VPN that routed all your phone's internet traffic through Facebook's servers before sending it anywhere else.

Facebook could see:

• Every app you opened
• How long you used it
• Which websites you visited
• And at what time you used each app
What did this mean for Facebook?

It meant that Zuck could see exactly which one of Facebook's competitor was growing popular among people.

Look how Facebook was tracking these apps (revealed in the court later): Image
By 2016, this data revealed Snapchat was exploding in popularity.

But there was one problem: Snapchat's traffic was encrypted, so Facebook couldn't see how people were using it.

In an email, Zuck says:
It seems important to figure out a way to get reliable analytics about them Image
Facebook's started "Project Ghostbusters" - named after Snapchat's ghost logo.

They would use "man-in-the-middle" attacks to break Snapchat's encryption.

Within a month, Facebook's engineers built "kits" that could intercept Snapchat's data before it got encrypted. Image
Facebook created custom client & server side code based on Onavo’s VPN proxy app.

This code included a client-side “kit” that installed a root certificate on Snapchat users’ mobile devices.

Then Facebook’s servers created fake digital certificates to impersonate Snapchat analytics servers to redirect & decrypt secure traffic from those apps to Facebook.Image
Seeing Snapchat's success, Zuckerberg offered to buy it for $3 billion.

But when Snap's CEO refused the offer, Facebook launched Snap's most famous feature on Instagram - Stories. Image
But this wasn't just about Snapchat.

Facebook used Onavo to systematically monitor Houseparty, YouTube, Amazon, and dozens of other apps.

Any rising competitor was identified, analyzed, and neutralized. Image
Apple forced Onavo off the App Store for violating privacy rules.

So Facebook rebranded it as "Facebook Research" and started paying teens $20/month to install it on their phones.

When Apple found out, they revoked Facebook's certificates, breaking ALL of Facebook's iOS apps. Image
Onavo shows how Big Tech weaponizes our trust.

33 million people installed privacy protection that was actually the most sophisticated corporate surveillance tool ever built.
Thanks for making it to the end!

8 Google engineers wrote the paper that every AI company now uses as their bible. OpenAI built GPT on it, Anthropic built Claude on it, and Meta built LLaMA on it.

Every LLM worth billions uses this paper's transformer architecture as the foundation...
Before 2017, teaching computers human language was torture.
AI would read text like humans reading through a keyhole - one word at a time.

They were slow, forgot context, and choked on long passages.
Then 8 researchers decided to flip things up... Image
They published an 8-page paper titled "Attention Is All You Need"

The idea was simple: Instead of reading word by word, why not look at everything at once? Like how you can glance at a page and immediately see which words relate to each other.

They called it a Transformer.

A Swedish non-profit operates the DNS billions of internet users depend on from Cold War bunkers.

They've had 100% uptime for 20+ years & they developed the invisible signatures that protect domains from hackers.

How they do it is interesting... Image
Without these signatures, hackers can hijack your DNS requests.

Which means that when you visit a website, you can be redirected to a fake site that looks same.

It's known as DNS poisoning & hackers just need to intercept your DNS request & send back a fake IP address to do it. Image
Enter DNSSEC - the cryptographic signatures I mentioned earlier...

Every DNS response now gets a mathematical signature that proves it came from the real server.

If someone tries to inject a fake response, your computer detects the missing signature and blocks it. Image

Three German brothers emailed eBay in 1999: "Let us run Germany for you."

eBay ignored them. So they cloned eBay, called it Alando, and made it so big that 100 days later eBay had to buy it for $43 million.

But what happened next was even more interesting... Image
The brothers - Marc, Oliver, and Alexander Samwer - turned this into a formula:

> Find successful US startups that hadn't expanded to Europe.
> Copy them exactly.
> Scale faster than the originals could expand.
> Sell it back to them or dominate.

They did this 100+ times. Image
The wildest was Airbnb. Brian Chesky flew to Berlin to meet their clone "Wimdu."

He walked into a converted factory with hundreds of people at desks. Each had two monitors: on the left, Wimdu on the right.

Copying every pixel change in real-time. Airbnb.com

Everyone thinks Apple is losing the AI race.

But Apple made their Neural Engine 60x more powerful.
Its M4 chip processes AI inputs 2X faster than rivals.

And they're quietly using the picks and shovel strategy used by Levi's during the California Gold Rush.

Thread Image
Image
Let's first go back to 1849.

A news headline about California having a lot of gold broke out.

Hundreds and thousands of people rushed to California digging for gold.

But most of them died or went completely broke.

However, there was a guy named Levi Strauss...
Levi Strauss noticed that the real money wasn't in mining gold.

It was in selling the tools every miner desperately needed.

So he started selling the picks, shovels, and pants to these miners.
(Levi's still has the logo that spoke to these miners)

But this doesn't end here... Image

Everyone's freaking out about Microsoft's deal with Nebius for $19.4 billion.

Two years ago, the same company was sanctioned and delisted from Nasdaq.

The founder fled from Russia with 1,300 engineers after condemning Putin's war.

Here's the wild story:
Microsoft's deal sent Nebius from $64 to $90 in hours.

$19.4 billion through 2031. That's 13x what Nebius made in all of 2024.

Microsoft had no choice though. They'd just lost their main GPU supplier to OpenAI... Image
But before we get to Microsoft's mess, you need to first meet Arkady Volozh, Yandex founder turned Nebius' CEO.

1989, working at a Soviet pipeline institute, he starts building search algorithms. Launches Yandex in 1997.

By 2021 he'd built something that made Google nervous... Image

Pentagon can't operate without it.
Netflix can't stream without it.
And banks can't trade without it.

Yet most people have never heard of Akamai.

How a $11 billion company operating on a 25-year-old mathematical equation secures 2 trillion of your interactions 🧵 Image
In 2024 alone, Akamai blocked 311 billion web attacks (that's 850 million attacks per day)

But the irony is that the Israeli commando who co-founded Akamai was the first victim to be stabbed on the 9/11 flight.

While Danny Lewin was dying, his algorithm was being tested... Image
After the 9/11 attacks, news sites started crashing.

Billions of people wanted to know what was happening and flooded these websites.

However, few websites which worked on Akamai's math stayed online.

But how does the math running 30% of the internet actually work? Image
