The Twitter accounts of major companies and individuals have been compromised in one of the most widespread and confounding hacks the platform has ever seen, all in service of promoting a bitcoin scam that appears to be earning its creator quite a bit of money.

We don’t know how the hack happened or even to what extent Twitter’s own systems may have been compromised — but following the unprecedented hacks of accounts including President Barack Obama, Joe Biden, Elon Musk, Bill Gates, Kanye West, Michael Bloomberg, and Apple, Twitter has confirmed it took the drastic step of blocking new tweets from every verified user, compromised or no, as well as locking all compromised accounts.

Twitter says it won’t restore access to their owners “until we are certain we can do so securely.”

On Wednesday evening, the company revealed that its own internal employee tools were compromised and used in the hack, which may explain why even accounts that claimed to have two-factor authentication were still attempting to fool followers with the Bitcoin scam.

The account takeovers appear to have subsided, but new scam tweets were posting to verified accounts on a regular basis starting shortly after 4PM ET and lasting more than two hours. Twitter acknowledged the situation after more than an hour of silence, writing on its support account at 5:45PM ET, “We are aware of a security incident impacting accounts on Twitter. We are investigating and taking steps to fix it. We will update everyone shortly.”

The company took the unprecedented measure of preventing verified accounts from tweeting at all starting sometime around 6PM ET. This would seem to be the first time Twitter has ever done this in the company’s history. Twitter updated its stance on limiting tweets at 7:18PM ET, writing, “We’re continuing to limit the ability to Tweet, reset your password, and some other account functionalities while we look into this. Thanks for your patience.” At 8:41PM ET, Twitter said “most” verified accounts should be able to tweet, adding, “As we continue working on a fix, this functionality may come and go.”

Late in the evening, Twitter CEO Jack Dorsey wrote, “Tough day for us at Twitter. We all feel terrible this happened. We’re diagnosing and will share everything we can when we have a more complete understanding of exactly what happened.” Product chief Kayvon Beykpour also released a public statement on his personal account, writing, “Our investigation into the security incident is still ongoing but we’ll be posting updates from @TwitterSupport with more detail soon. In the meantime I just wanted to say that I’m really sorry for the disruption and frustration this incident has caused our customers.”

The chaos began when Tesla CEO Elon Musk’s Twitter account was seemingly compromised by a hacker intent on using it to run a bitcoin scam. Microsoft co-founder Bill Gates’ account was also seemingly accessed by the same scammer, who posted a similar message with an identical bitcoin wallet address. Both accounts continued to post new tweets promoting the scam almost as fast as they were deleted, and Musk’s account in particular was still be under the control of the hacker as late as 5:56PM ET.

A spokesperson for Gates tells Recode’s Teddy Schleifer, “We can confirm that this tweet was not sent by Bill Gates. This appears to be part of a larger issue that Twitter is facing. Twitter is aware and working to restore the account.”

Shortly after the initial wave of tweets from Gates and Musk’s accounts, the accounts of Apple, Uber, former President Barack Obama, Amazon CEO Jeff Bezos, Democratic presidential candidate Joe Biden, hip-hop mogul Kanye West, and former New York City mayor and billionaire Mike Bloomberg, among others, were also compromised and began promoting the scam.

It’s unclear how widespread the operation is, but it appears to have affected numerous major companies and extremely high-profile individuals. That suggests someone, or a group, has either found a severe security loophole in Twitter’s login or account recovery process or those of third-party app — or that the perpetrator has somehow gained access to a Twitter employee’s admin privileges. According to Motherboard, numerous underground hacking circles have been sharing screenshots of an internal Twitter administration tool allegedly used to take over the high-profile verified accounts. Twitter is now removing images of the screenshot from its platform and in some cases suspending users who continue to share it.

So far, Twitter has confirmed that employee tools were used in the hack, but not which ones or more than a theory as to how hackers might have gotten access.

The origin of the scam can be traced to the moment when Musk’s account issued a mysterious tweet at 4:17PM ET reading, “I‘m feeling generous because of Covid-19. I’ll double any BTC payment sent to my BTC address for the next hour. Good luck, and stay safe out there!” The tweet also contained a bitcoin address, presumably one associated with the hacker’s crypto wallet.

The tweet was then deleted and replaced by another one more plainly laying out the fake promotion. “Feeling grateful doubling all payments sent to my BTC address! You send $1,000, I send back $2,000! Only doing this for the next 30 minutes,” it read before also getting deleted. The tweet posted to Gates’ account echoed the Musk tweets, with an identical BTC address attached. It was also deleted shortly after posting, only for a similar message to take its place a few minutes later.

Square’s Cash App appears to be one of the other rare company accounts compromised. However, it’s not clear if the culprit is the same or if this is some form of a coordinated scam on behalf of a group, as the tweet contained a different BTC address than the ones posted to the other accounts.

In addition to the Cash App, popular crypto Twitter accounts, including those of Cameron and Tyler Winklevoss’ Gemini cryptocurrency exchange and widely used wallet app Coinbase, were also compromised. Cameron Winklevoss claims the Gemini account was protected by two-factor authentication and used a strong password, and the company is now investigating how it was hit.

Some people apparently fell for the scam and sent money to the associated BTC address, as records of the transactions are public due to the nature of the blockchain-based cryptocurrency. So far, the scammer have amassed nearly $120,000, although it seems as if the account owner is indeed sending money back out as the daily final balance has fluctuated up and down throughout the afternoon.

Musk has long been the target of bitcoin scammers on Twitter, many of whom create fake accounts designed to look like the entrepreneur and respond to his tweets promoting the scams so that they appear legitimate. Twitter even went so far as to start locking some accounts that change their name to “Elon Musk,” and the company singled out cryptocurrency scammers in spring 2018 as a source of known manipulation and deception that it was aiming to root out through bans and other moderation strategies.
