Olivia
Late on a Tuesday night in July 2020, a hacker sends a message on Discord. "Yoo bro. I work at Twitter. Don't show this to anyone. Seriously."
Sean
And did he? Work at Twitter?
Olivia
He was seventeen, and he lived in Tampa, Florida.
Sean
So that's a no.
Olivia
That's a no. But by the next evening, he was tweeting as Barack Obama.
Sean
This is Aprendos English, level B2. I'm Sean.
Olivia
And I'm Olivia.
Sean
I remember this one. Obama, Elon Musk and Bill Gates all offered to double your bitcoin on the same afternoon.
Olivia
And Apple, and Uber, and Joe Biden, who was running for president at the time.
Sean
I always assumed it was some big criminal gang, possibly paid by a government. Russia, maybe?
Olivia
That's what a lot of people thought that evening. In fact, it was a small group of young guys who mostly knew each other from online forums.
Sean
So how does a teenager get inside one of the biggest tech companies in the world?
Olivia
With a phone. The New York State financial the whole thing afterwards, and their report says there was no malware at all.
Sean
Just a phone call?
Olivia
Several phone calls, actually. On the afternoon of July the fourteenth, one or more of the hackers started ringing Twitter employees at home.
Sean
At home, because of the pandemic.
Olivia
Exactly. Twitter had sent everybody home in March, so the whole company was connecting through a VPN, a kind of secure tunnel…
Sean
…which I imagine kept breaking.
Olivia
All the time, according to the report. So the hackers claimed to be the IT help desk, calling about a reported problem with the employee's VPN.
Sean
Which was probably true.
Olivia
Very likely! Then they sent the employee to a fake website that looked exactly like Twitter's real VPN login page.
Sean
But surely Twitter had two-factor authentication. You type your password, and then your phone asks you to confirm it's really you.
Olivia
They did. But while the employee was typing their password into the fake page, the hackers were typing it into the real one.
Sean
Oh, that's clever. So the employee's phone buzzes…
Olivia
…and they tap "yes, it's me," because they think they're just logging in.
Sean
So they've opened the door themselves.
Olivia
The callers also knew personal details about the employees, which made them sound . Some employees reported the calls as , but at least one didn't.
Sean
My mum would have that in about four seconds. She keeps all her passwords in a notebook next to the kettle, with a label on the front that says "Passwords."
Olivia
Sean, that's the first place a burglar would look.
Sean
I've told her that. She says burglars don't read.
Olivia
Okay, so they're inside, but the first employee they fooled couldn't actually take over accounts.
Sean
So it was a ?
Olivia
Not quite. They used that access to explore Twitter's internal websites, which explained how the other tools worked. So on July the fifteenth, they went after the people who had the powerful tools.
Sean
How many people had those tools?
Olivia
Guess.
Sean
Ten? Maybe twenty senior…
Olivia
…over a thousand, according to the regulator.
Sean
A thousand people could take over any account on Twitter?
Olivia
More or less. With those tools you could change the email address linked to an account, and then reset the password.
Sean
That's rather a lot of spare keys for one house.
Olivia
And the company didn't even have a head of security at the time, because the last one had left seven months earlier.
Sean
Right. So, a teenager with the keys to Twitter. He goes straight for Elon Musk, surely.
Olivia
You'd think so, but he actually went shopping for usernames first.
Sean
Usernames?
Olivia
Have you heard of OG handles? OG stands for "original gangster." They're very short Twitter names, just one letter or one number, like the letter y or the number six.
Sean
And people pay money for those?
Olivia
Thousands of dollars. Early users grabbed them in Twitter's first years, and people who arrived later want them as a . There's even a forum called OGUsers, where people buy and sell them.
Sean
I'm sorry, but I don't understand that at all.
Olivia
You're the man who owns a cricket bat signed by people you've never met.
Sean
That's history, Olivia. A single letter on the internet is hardly the same thing.
Olivia
It is to them. So Kirk, the name our teenager used on Discord, needed people who could sell the handles for him…
Sean
….
Olivia
Middlemen. Two guys who called themselves "lol" and "ever so anxious."
Sean
Brilliant names. Very .
Olivia
Extremely. According to the New York Times, one of the first deals was the handle y. It went for fifteen hundred dollars in bitcoin.
Sean
For the letter y.
Olivia
For the letter y. And "ever so anxious" took the handle "anxious" for himself, because he'd wanted it for years.
Sean
So these two actually believed that Kirk worked at Twitter?
Olivia
Not for long. Within about a day, "lol" decided Kirk couldn't possibly be an employee, because he was far too happy to damage the company.
Sean
Fair point, actually. A real employee would at least worry about his pension.
Olivia
By the afternoon, though, Kirk seemed bored of selling letters. Just before two o'clock, some of the stolen accounts started tweeting screenshots of Twitter's secret internal tools.
Sean
He was .
Olivia
He was totally showing off, and then at around quarter past two the bitcoin began.
Sean
I bet it was Musk first, because he's the obvious one.
Olivia
Wrong again. They started with a cryptocurrency trader, then moved on to big crypto companies like Binance and Coinbase.
Sean
Why start with the smaller accounts?
Olivia
Nobody knows for sure. Maybe it was a test, or maybe they thought crypto fans would be the easiest people to convince. One message from Kirk that afternoon just says, "we just hit cb."
Sean
CB for Coinbase, I assume.
Olivia
Yep. And a little after four o'clock, the famous names started falling. Musk, Gates, Kanye West and Warren Buffett all went within about two hours…
Sean
…and Obama.
Olivia
And Obama. Biden's tweet said, "I am giving back to the community. All Bitcoin sent to the address below will be sent back doubled!"
Sean
That's it?
Olivia
Then, "If you send a thousand dollars, I will send back two thousand. Only doing this for thirty minutes."
Sean
Only thirty minutes, so you don't have time to think.
Olivia
Which is the oldest trick in the book. Apple's account said something similar, that the company supported Bitcoin and would double everything people sent.
Sean
Apple, of all companies. They won't even give you a phone charger in the box these days.
Olivia
Doubling your money is apparently easier.
Sean
Hang on. What was Twitter doing while all this was happening?
Olivia
Their security team had been looking into strange phone calls since that morning. Once the crypto accounts started falling, however, it took them hours to throw the hackers out.
Sean
Hours? For a company that size?
Olivia
Their first public statement didn't come until about quarter to six in the evening. And then they did something quite dramatic…
Sean
…oh, I remember this, actually. They stopped verified accounts from tweeting, didn't they?
Olivia
That's right, and loads of blue tick accounts suddenly couldn't post anything at all.
Sean
Which caused its own problems. The National Weather Service in the US couldn't tweet a tornado warning that evening.
Olivia
Wait, seriously?
Sean
Seriously. And there's another detail I love about Twitter's own staff. According to the report, every employee had to change their password on a video call while a supervisor watched them.
Olivia
Every single employee?
Sean
Starting with the boss, Jack Dorsey. Imagine being the CEO while your supervisor watches you type "password one two three."
Olivia
I refuse to believe Jack Dorsey's password was password one two three.
Sean
We'll never know. So, the big question. How much money did Kirk make?
Olivia
You tell me.
Sean
Millions, surely. Obama alone had over a hundred million followers.
Olivia
About a hundred and eighteen thousand dollars, according to the regulator. Prosecutors in Florida said a hundred and seventeen thousand, and one early report put it at over a hundred and eighty.
Sean
That's all? With access to half the famous people on the planet?
Olivia
The crypto exchanges blocked the scam addresses very quickly. Coinbase alone stopped more than five thousand transfers, worth about one point three million dollars.
Sean
So they stopped more than ten times what was actually stolen.
Olivia
Exactly. Although plenty of people still paid. The Justice Department said the scam wallet received more than four hundred transfers.
Sean
Four hundred payments from people who believed Bill Gates was giving away money on a Wednesday afternoon.
Olivia
My grandmother nearly fell for something like that. A man rang her pretending to be her bank, and he was so polite that she nearly read him her card number. She only stopped because she couldn't find her glasses.
Sean
Saved by bad eyesight.
Olivia
She's very proud of it. Okay, so a hundred and thirty accounts were attacked in total, and forty-five were used to send tweets. The hackers also got into the private messages of up to thirty-six accounts.
Sean
Whose messages? Please don't say Obama's.
Olivia
Twitter said only one elected politician had their private messages read, a Dutch MP called Geert Wilders.
Sean
And the American president? Trump was in the White House at the time.
Olivia
His account wasn't touched. The Verge suggested his account had extra protection, but that's never been fully explained.
Sean
So, how did they catch them? Because I thought bitcoin was completely anonymous.
Olivia
Everyone thinks that. Can you guess?
Sean
Somebody about it online. It's always the bragging with these people.
Olivia
Partly right, because some of the hackers actually gave interviews to the New York Times two days later…
Sean
…you're joking.
Olivia
I'm not. But the real problem for them was the money itself.
Sean
Oh, this is where I come in, actually. I read the Justice Department's press release about this.
Olivia
Be my guest.
Sean
Every bitcoin payment is recorded on a public list called the blockchain, so anyone can follow the money from wallet to wallet. Tax investigators from the IRS did exactly that, with help from a company called Chainalysis. Eventually the money reached ordinary crypto exchanges, like Coinbase and Binance…
Olivia
…and those exchanges want to know who you are.
Sean
They certainly do. According to the charges, the British member of the group had verified his accounts using his own driving licence. The man in Orlando did the same thing with his Coinbase account.
Olivia
So they basically signed their names on it.
Sean
With a photo. Their real names came out on the thirty-first of July. Mason Sheppard, nineteen, from Bognor Regis in England, was "Chaewon." Nima Fazeli, twenty-two, from Orlando, was "Rolex."
Olivia
So which of them was "ever so anxious"?
Sean
Honestly, I couldn't find a clear answer, because the official papers use different nicknames.
Olivia
Fine. And the teenager in Tampa?
Sean
He was arrested early that same morning, at an apartment where he lived by himself.
Olivia
By himself? At seventeen?
Sean
Apparently so. His name is Graham Ivan Clark.
Olivia
Now, he was a minor at the time, so the federal authorities didn't name him. Because he was a juvenile, they passed his case to prosecutors in Florida.
Sean
So why do we know his name?
Olivia
Florida allows minors to be charged as adults in some financial fraud cases, and prosecutors decided to do exactly that. The State Attorney announced his full name, and every major newspaper has used it since.
Sean
How many charges?
Olivia
Thirty felonies, including organised fraud and fraudulent use of personal information. The prosecutor, Andrew Warren, told reporters, "This was not an ordinary seventeen-year-old."
Sean
I suppose not. Most seventeen-year-olds are just trying to pass their driving test.
Olivia
And his was set at seven hundred and twenty-five thousand dollars…
Sean
…which, for a teenager, is…
Olivia
…no problem at all, according to his lawyer. He said Clark already owned more than three million dollars in bitcoin.
Sean
Three million? From where?
Olivia
Hold that thought.
Sean
Fine. So he goes to trial?
Olivia
He never did. In March 2021 he , by video from the county jail where he'd been since his arrest. He was eighteen by then.
Sean
And the sentence?
Olivia
Three years in prison, followed by three years of .
Sean
Three years? For hacking Obama? I expected at least…
Olivia
…ten, and that was the minimum for an ordinary adult. But the deal let him be sentenced as a "youthful offender," which is a Florida rule for people under twenty-one.
Sean
That seems rather generous to me, if I'm honest.
Olivia
I think it's fair. He was a kid…
Sean
…a kid who fooled a billion-dollar company and took money from hundreds of strangers.
Olivia
Seventeen, Sean. The prosecutor said the goal was to teach him a lesson without destroying his future. He'd already spent over seven months in jail, and he might even serve part of it in a military-style boot camp.
Sean
Boot camp. Well, I hope they make him run a lot.
Olivia
There were other conditions as well. He couldn't use computers without permission and supervision from the police. He also had to hand over his passwords.
Sean
I hope he kept them in a notebook next to the kettle.
Olivia
Your mum should work for the police.
Sean
So what about Twitter afterwards? Did anything actually change?
Olivia
Quite a lot, in the end. In September 2020 they finally hired a new head of security. They also started replacing phone notifications with physical security keys, which you plug into your computer.
Sean
And a phone call can't trick a USB stick.
Olivia
True. The regulator argued that big social media companies are now so important for news and elections that they need their own regulator.
Sean
And imagine if the next hackers are cleverer, because one fake tweet from a president could move markets.
Olivia
The prosecutor made exactly that point. And remember PlugwalkJoe?
Sean
No, you haven't mentioned him.
Olivia
Oh, sorry, I skipped him! He was a British hacker who got the handle six that day. He told the New York Times he'd been getting a massage in Spain while it all happened. About the police, he said, "They can come arrest me. I would laugh at them."
Sean
Oh dear. I can see where this is going.
Olivia
In 2023 he was extradited from Spain to the US and pleaded guilty in New York. That June he got five years, for the Twitter hack and several other cybercrimes.
Sean
Five years. That's two more than Clark, although Clark was sentenced as a youthful offender.
Olivia
I don't think he's laughing anymore.
Sean
No, probably not.
Olivia
Okay, folks, your verdict. Would three years have been fair for a grown adult who did exactly the same thing? Put it in the comment section.
Sean
Before anyone goes, though, you told me to hold a thought. Where did the three million come from?
Olivia
In 2019, hackers took over a Seattle investor's phone number and stole a hundred and sixty-four bitcoins. One of the extortion notes was signed "Scrim," which several of his online friends said was one of Clark's online names.
Sean
Wait. So the police knew about him before Twitter?
Olivia
In April 2020, three months before the hack, the Secret Service took a hundred bitcoins from Clark that matched the stolen coins. According to his own lawyer, investigators also gave him back three hundred more, because they'd decided not to charge him.
Sean
So they handed him three hundred bitcoins, and three months later he hacked Twitter.
Olivia
Seriously. Every twist is in a PDF you can download for free, linked below. Stay safe online, everyone.
Sean
Yes, and mind who you give your password to.
