OpenSea staffer charged with insider-trading of NFTs

From Non-Fungible Tokens to No Freedom, Twit, if convicted


A now-former product boss at a top NFT marketplace was arrested and charged with wire fraud and money laundering in the first-ever insider-trading case involving the digital tokens.

Nathaniel Chastain, 31, was employed at OpenSea, the largest online bazaar of its kind, from January to September 2021. OpenSea is essentially a place where people buy and sell NFTs of things; NFTs being not much more than an electronic receipt on a blockchain in practice but that's another story.

Chastain resigned from his position as head of product after his employers learned he was secretly purchasing, using anonymous accounts, numerous NFTs of cartoon images and artwork knowing the content was about to be featured on OpenSea's marketplace, it is claimed.

When the material was highlighted on the site and the tokens rocket in value, Chastain would then sell the NFTs at much higher prices than he had bought them for, pocketing the profits, it is alleged. As an employee, Chastain knew in advance when stuff was going to be spotlighted.

"NFTs might be new, but this type of criminal scheme is not," Damian Williams, an attorney for the Southern District of New York, said this week. "As alleged, Nathaniel Chastain betrayed OpenSea by using its confidential business information to make money for himself. [The] charges demonstrate the commitment of this office to stamping out insider trading – whether it occurs on the stock market or the blockchain."

OpenSea's co-founder and CEO Devin Finzer commissioned a third party to investigate incidents of insider trades last year.

"As the world's leading web3 marketplace for NFTs, trust and integrity are core to everything we do," a company spokesperson told The Register in a statement.

"When we learned of Nate's behavior," they further claimed, "we initiated an investigation and ultimately asked him to leave the company. His behavior was in violation of our employee policies and in direct conflict with our core values and principles."

Chastain was accused of setting up various secret cryptocurrency wallets to buy the NFTs before they were featured on OpenSea, and was apparently spotted when they were sold and profits were transferred into his own account:

He had a good idea ahead of time which images could be sold at higher prices because he was responsible for choosing which ones to go up on OpenSea's homepage. When the NFTs went live, traders could then bid for them. Chastain often resold the assets for two-to five-times their initial purchase price, it's claimed. 

"In this case, as alleged, Chastain launched an age-old scheme to commit insider trading by using his knowledge of confidential information to purchase dozens of NFTs in advance of them being featured on OpenSea's homepage," FBI assistant director-in-charge Michael Driscoll involved in the Department of Justice's investigation, said.

"With the emergence of any new investment tool, such as blockchain supported non-fungible tokens, there are those who will exploit vulnerabilities for their own gain. The FBI will continue to aggressively pursue actors who choose to manipulate the market in this way."

Chastain was charged with one count of wire fraud and one count of money laundering; each charge carries a maximum sentence of 20 years in prison. ®

    Miscreants exploited a now-fixed design flaw in the Rarible NFT marketplace to steal a non-fungible token from Taiwanese singer and actor Jay Chou and sell it for about $500,000.

    That's according to folks at Check Point, who on Thursday said the vulnerability could have been abused by crooks to gain full control of victims' marketplace accounts and the funds in them. Earlier this month, Chou said his NFT was stolen in what looked like a phishing attack.

    When researchers Roman Zaikin, Dikla Barda and Oded Vanunu investigated the security shortcoming they found that fraudsters could lure users to click on a link to malicious NFT, enabling them to take control of their marks' Rarible accounts using a standard called EIP-721.

  • SEC nearly doubles cryptocurrency cop roles in special cyber unit
    Policing digital assets sounds more Mission Impossible than NCIS

    The US Securities and Exchange Commission intends to fill an additional 20 positions in a special unit that polices cryptocurrency fraud and other cybercrimes.

    This brings the newly renamed Crypto Assets and Cyber Unit's total to 50 roles as the SEC hopes to crack down on miscreants trying to profit from growing interest in digital assets and marketplaces.

    "As more investors access the crypto markets, it is increasingly important to dedicate more resources to protecting them," SEC Chair Gary Gensler said in a canned statement. "By nearly doubling the size of this key unit, the SEC will be better equipped to police wrongdoing in the crypto markets while continuing to identify disclosure and controls issues with respect to cybersecurity."

  • Flaw could have granted criminals control over Ever Surf crypto wallets
    Check Point uncovers web vulnerability that could have led to cryptocurrency theft

    A flaw detected in the browser version of the Ever Surf cryptocurrency wallet could have given hackers who exploited it full control over a targeted user's wallet, say threat hunters at Check Point Research.

    The security vulnerability made it possible for threat actors to decrypt the private keys and seed phrases found in the browser's local storage, opening the door to cracking the victim's wallet and accessing the cryptocurrency stored there, the researchers wrote in a blog post Monday.

    "As the browser's local storage is unprotected, the data stored there must be securely encrypted," they wrote. "Despite the fact that Surf uses reliable cryptographic libraries for the key derivation and the encryption, the sensitive data in the web version of Surf doesn't appear to have adequate protection."

    Activision Blizzard is under investigation for possible insider trading including claims CEO Bobby Kotick tipped off some investors to buy more shares before the $68.7bn Microsoft acquisition deal was announced.

    The American games maker, known for top series such as World of Warcraft and Call of Duty, said it was cooperating with the Securities Exchange Commission and the Department of Justice, according to a securities filing.

    "Activision Blizzard received a voluntary request for information from the SEC and a grand jury subpoena from the DOJ, both of which appear to relate to their respective investigations into trading by third parties – including persons known to Activision Blizzard's CEO – in securities prior to the announcement of the proposed transaction," the company stated on Friday in an 8-K submission.
