Nearly all of the $600 million stolen in a huge crypto heist has been returned — but there’s a catch
Nearly all of the $600 million stolen in one of the biggest cryptocurrency heists ever has now been returned by hackers.
Poly Network, the crypto platform targeted in the attack, said Thursday that all of the funds bar $33 million worth of the digital coin tether had been transferred.
The issuer of tether, a so-called stablecoin pegged to the U.S. dollar, used a built-in failsafe to freeze the assets soon after the theft.
In an unusual turn of events Wednesday, an anonymous person claiming to be the hacker said they were “ready to return” the funds. The identity of the hacker, or hackers, is not yet known.
Poly Network requested they send the money to three digital currency wallets. And, sure enough, the hacker had returned more than $342 million of the funds to those wallets by Thursday.
But there’s a catch. While almost all of the haul has been sent back to Poly Network, the last $268 million of assets is currently locked in an account that requires passwords from both Poly Network and the hacker to gain access.
“It’s likely that keys held by both Poly Network and the hacker would be required to move the funds — so the hacker could still make these funds inaccessible if they chose to,” Tom Robinson, chief scientist of blockchain analytics firm Elliptic, said in a blogpost Friday.
In a message embedded in a digital currency transaction, the suspected hacker said they would “provide the final key when _everyone_ is ready.”
Record ‘DeFi’ hack
Poly Network is what’s known as a “decentralized finance,” or DeFi, system. DeFi projects aim to use blockchain — the technology which underpins most cryptocurrencies — to replicate traditional financial services like loans and trading.
In Poly Network’s case, the DeFi system allows users to transfer tokens from one blockchain to another.
Someone exploited a vulnerability in Poly Network’s code which allowed them to transfer tokens to their own crypto wallets. The platform lost more than $610 million in the attack, according to researchers at security firm SlowMist.
Poly Network called it “the biggest in defi history.”
The self-proclaimed hacker claims they carried out the theft “for fun” and that it was “always the plan” to eventually return the funds.
CNBC could not independently verify the authenticity of the messages.
In a further message, the hacker claimed Poly Network offered them a $500,000 bounty to send all of the money back, and that they turned it down. The hacker shared what appears to be a statement from Poly Network promising that they would “not be held accountable for this incident,” effectively granting them immunity.
Poly Network did not return a request for comment from CNBC by the time of publication.
“Offering immunity may have sounded like a smart move from Poly Network to dangle a carrot, but it is unlikely that the authorities would agree with this decision nor even allow it,” said Jake Moore, a specialist at cybersecurity firm ESET.
“This attack is likely to have been watched closely by cybercriminals and law enforcement alike, potentially opening up the possibility of copycat attacks.”
Identifying the hacker
Robinson said the hacker “might well still find themselves being pursued by the authorities.”
“Their activities have left numerous digital breadcrumbs on the blockchain for law enforcement to follow.”
Cryptocurrencies are often the go-to for cybercriminals, particularly in ransomware attacks which lock down organizations’ systems or steal data while demanding a ransom payment to recover access.
That’s because the people sending and receiving digital currencies aren’t revealing their identities. However, it has become possible to trace the location of the funds by analyzing the blockchain, which contains a public record of all historical crypto transactions.

Nintendo on Friday announced that retail preorder for its Nintendo Switch 2 gaming system will begin on April 24 starting at $449.99.
Preorders for the hotly anticipated console were initially slated for April 9, but Nintendo delayed the date to assess the impact of the far-reaching, aggressive “reciprocal” tariffs that President Donald Trump announced earlier this month.
Most electronics companies, including Nintendo, manufacture their products in Asia. Nintendo’s Switch 1 consoles were made in China and Vietnam, Reuters reported in 2019. Trump has imposed a 145% tariff rate on China and a 10% rate on Vietnam. The latter is down from 46%, after he instituted a 90-day pause to allow for negotiations.
Nintendo said Friday that the Switch 2 will cost $449.99 in the U.S., which is the same price the company first announced on April 2.
“We apologize for the retail pre-order delay, and hope this reduces some of the uncertainty our consumers may be experiencing,” Nintendo said in a statement. “We thank our customers for their patience, and we share their excitement to experience Nintendo Switch 2 starting June 5, 2025.”
The Nintendo Switch 2 and “Mario Kart World“ bundle will cost $499.99, the digital version “Mario Kart World” will cost $79.99 and the digital version of “Donkey Kong Bananza” will cost $69.99, Nintendo said. All of those prices remain unchanged from the company’s initial announcement.
However, accessories for the Nintendo Switch 2 will “experience price adjustments,” the company said, and other future changes in costs are possible for “any Nintendo product.”
It will cost gamers $10 more to by the dock set, $1 more to buy the controller strap and $5 more to buy most other accessories, for instance.

Etsy is trying to make it easier for shoppers to purchase products from local merchants and avoid the extra cost of imports as President Donald Trump’s sweeping tariffs raise concerns about soaring prices.
In a post to Etsy’s website on Thursday, CEO Josh Silverman said the company is “surfacing new ways for buyers to discover businesses in their countries” via shopping pages and by featuring local sellers on its website and app.
“While we continue to nurture and enable cross-border trade on Etsy, we understand that people are increasingly interested in shopping domestically,” Silverman said.
Etsy operates an online marketplace that connects buyers and sellers with mostly artisanal and handcrafted goods. The site, which had 5.6 million active sellers as of the end of December, competes with e-commerce juggernaut Amazon, as well as newer entrants that have ties to China like Temu, Shein and TikTok Shop.
By highlighting local sellers, Etsy could relieve some shoppers from having to pay higher prices induced by President Trump’s widespread tariffs on trade partners. Trump has imposed tariffs on most foreign countries, with China facing a rate of 145%, and other nations facing 10% rates after he instituted a 90-day pause to allow for negotiations. Trump also signed an executive order that will end the de minimis provision, a loophole for low-value shipments often used by online businesses, on May 2.
Temu and Shein have already announced they plan to raise prices late next week in response to the tariffs. Sellers on Amazon’s third-party marketplace, many of whom source their products from China, have said they’re considering raising prices.
Silverman said Etsy has provided guidance for its sellers to help them “run their businesses with as little disruption as possible” in the wake of tariffs and changes to the de minimis exemption.
Before Trump’s “Liberation Day” tariffs took effect, Silverman said on the company’s fourth-quarter earnings call in late February that he expects Etsy to benefit from the tariffs and de minimis restrictions because it “has much less dependence on products coming in from China.”
“We’re doing whatever work we can do to anticipate and prepare for come what may,” Silverman said at the time. “In general, though, I think Etsy will be more resilient than many of our competitors in these situations.”
Still, American shoppers may face higher prices on Etsy as U.S. businesses that source their products or components from China pass some of those costs on to consumers.
Etsy shares are down 17% this year, slightly more than the Nasdaq.
