@bitcoin, @ripple, @coindesk, @coinbase and @binance were among the accounts hacked with the same message: "We have partnered with CryptoForHealth and are giving back 5000 BTC to the community," followed by a link to a website, which we are not linking to.
Some of the accounts were quickly back under their owners' control and tweets were quickly deleted. At the time of writing, both Binance and Bitcoin still had a tweet promoting the scam. @Apple also had its account hacked to push the same scam, as well as Amazon co-founder @jeffbezos.
The scammer's website was quickly pulled offline. Kristaps Ronka, chief executive of Namesilo, the domain registrar used by the scammers, told TechCrunch that the company suspended the domain "on the first report" it received.
Many other accounts were quickly hijacked, including @elonmusk. The tweet posted to the Tesla and SpaceX founder's account simply directed users to send bitcoin to a certain address under the guise that he will "double any payment" — a known cryptocurrency scam technique.
@billgates' account was also briefly hacked with the same message, though the tweet was quickly deleted.
These kinds of scams are common. Scammers take over high-profile Twitter accounts using breached or leaked passwords and post messages that encourage users to post their cryptocurrency funds to a particular address under the guise that they'll double their "investment." In reality, it's simple theft, but it's a scam that works. By the time of writing, the blockchain address used on the scam site had already collected 2.8 bitcoin — some $25,700 in today's currency — and it's going up by the minute.
A spokesperson for Binance told TechCrunch: "The security team is actively investigating the situation of this coordinated attack on the crypto industry." Several other companies affected by the account hacks did not immediately respond to a request for comment.
It's not immediately known how the account hacks took place. Security researchers, however, found that the attackers had fully taken over the victims' accounts, and also changed the email address associated with the account to make it harder for the real user to regain access.
Scammers frequently reply to high-profile accounts, like celebrities and public figures, to hijack the conversation and hoodwink unsuspecting victims. Twitter typically shuts these accounts down pretty fast.
A Twitter spokesperson, when reached, said the company was "looking into" the matter but didn't immediately comment. Twitter CEO Jack Dorsey’s Twitter account was also hacked.
