Crypto scam money launderers charged for laundering more than $73 million through Deltec

Two people were charged in California for laundering money obtained from cryptocurrency and fiat "pig butchering" scams. After receiving the money from the investment scammers, the launderers then allegedly helped to obfuscate at least $73 million in transactions by moving the money through Deltec Bank in The Bahamas and converting it into the Tether stablecoin.

Deltec is a well-known bank in the cryptocurrency world, mostly for its ties to Tether and to FTX. In July 2023, US authorities seized tens of millions from Deltec accounts in connection to a cryptocurrency money laundering investigation. It's not clear if that was the same investigation.

Aiden Pleterski, a 25-year-old who goes by "Crypto King", has finally been arrested and charged with fraud and money laundering. In 2022, he was sued by a group of investors who have lost at least CA$41.5 million (~US$30.5 million) they entrusted to him to invest on their behalf. He had promised massive profits, and told them that any losses on their initial investments would be repaid in full. A judge froze his assets in July 2022, and the court ordered him and his company into bankruptcy the following month. The bankruptcy proceedings have so far recovered around CA$3 million (US$2.2 million).

Investigators for the bankruptcy proceedings found that Pleterski had invested less than 2% of customer funds. Around $16 million instead went to personal expenses, including luxury cars, a $45,000-a-month lakefront mansion, private jets, and vacations.

Even after being sued, filing for bankruptcy, and being kidnapped and beaten by angry investors, Pleterski flaunted his supposed wealth online. Much to the indignation of the creditors in his bankruptcy, he has continued to regularly livestream himself gambling for hours, spending $150,000 on Legos, and driving luxury cars.

Pleterski was released the same day he was arrested, thanks to a CA$100,000 (~US$75,000) surety bond posted by his parents.

Pump.fun suffers $2 million loss to former employee who claims he wanted to "kill" the project for "inadvertently hurt[ing] people"

Pump.fun is a Solana-based memecoin generator that soared to popularity recently amid a resurgence in memecoin trading. On May 16, the project suffered a $2 million exploit by an attacker who then began airdropping the money to somewhat random wallets.

A former employee — whose real identity is known — brazenly took credit for the theft on Twitter. They wrote: "everybody be cool, this is a r o b b e r y. ... I'm about to change the course of history. n then rot in jail. am I sane? nah. am I well? v much not. do I want for anything? my mom raised from the dead n barring that: life without parole."

In a Twitter Spaces chat, the attacker stated that he had worked for the company briefly, and that he had grievances against its management. "I just kind of wanted to kill Pump.fun because it's something to do... It's inadvertently hurt people for a long time," he said.

Pump.fun paused trading shortly after the attack, and stated that they were "cooperating with relevant parties, including law enforcement, to minimize the damage." The attacker responded to the post: "Neener neener neener".

Brothers indicted for $25 million MEV bot exploit

Two brothers, Anton and James Peraire-Bueno, were indicted for a theft involving MEV — maximal extractable value. MEV involves previewing upcoming transactions on a blockchain and taking actions to extract additional profits — which can sometimes be substantial — based on that information.

According to the Justice Department, the Peraire-Buenos exploited a flaw in popular MEV software called "MEV-boost", which is used by most Ethereum validators. By creating their own validators and "bait transactions", they were able to trick MEV bots into proposing transactions involving illiquid cryptocurrencies, which the brothers then frontran. They were able to create false signatures that tricked a MEV-boost relay into releasing information about upcoming blocks that they were able to tamper with.

The brothers were charged with conspiracy to commit wire fraud, wire fraud, and conspiracy to commit money laundering, and face up to 20 years in prison for each charge.

The Justice Department is describing the case as a "first-of-its-kind manipulation of the Ethereum blockchain". The case is an interesting one, as some believe the practice of MEV itself exploits Ethereum users. Others believe anything you can do with code should be allowed — "code is law". However, by signing false transactions and tricking the relay into releasing private information, the brothers' actions do seem to go beyond simply making profits in a "code is law" Wild West, and into the realm of actual fraud.

$2 million stolen from ALEX's XLink bridge by bumbling exploiter

An attacker tried to pull off what could have been a ~$12 million heist from ALEX Lab's XLink bridge after a private key was compromised. However, the sloppy work by the attacker enabled an apparent whitehat hacker to step in.

The attacker was successfully able to transfer around 13.8 million STX (~$2 million) on the Stack BTC layer-2 chain. However, their attempts to steal assets notionally worth around $4.3 million from the project's BNB Chain implementation failed when they upgraded the project contract to a malicious version, but failed to prevent other people from calling the withdraw function. The attacker's first transactions to withdraw the funds themself failed, and an apparent whitehat hacker was able to step in and complete the withdrawal ahead of the exploiter. They later negotiated a deal for the funds' return, after offering a 10% "bounty".

The exploiter had also tried, and failed, to steal assets notionally worth around $5 million on the Ethereum blockchain, but failed to do so. ALEX Lab later announced they were able to recover or secure around $4.5 million of those assets.

Tornado Cash developer sentenced to more than five years imprisonment in the Netherlands

Alexey Pertsev, one of the developers of the Tornado Cash mixing service, was found guilty of money laundering and sentenced to 64 months imprisonment in the Netherlands. Prosecutors claimed that Pertsev knew the service was being used to launder money, but "chose not to intervene". They argued that, although the developers could not necessarily prevent bad actors from laundering money through the service directly, they could have done more to prevent people from using the web interface to wash funds from known criminal wallets.

The case is a concerning one, as sanctioning software developers for how the code they write is used — particularly when it comes to software intended to protect privacy — has frightening implications. Although there is some precedent in the United States that "code is speech", and merely writing and publishing code is protected by the First Amendment, that obviously does not apply to the Netherlands. A collaborator to Pertsev, Roman Storm, is set to be tried on charges of money laundering and sanctions violations in the United States in September, and that case is likely to grapple with this exact issue.

Sonne Finance hacked for at least $20 million

The Sonne Finance lending protocol was exploited for at least $20 million as an attacker was able to exploit a vulnerability in some of their smart contracts. Sonne is a fork of the Compound Finance project, which has known vulnerabilities that are sometimes not properly addressed by people who reuse the code — as has happened with Radiant Capital and Rari.

After being alerted to the theft by several security companies, Sonne announced they had paused the contract on the Optimism Ethereum layer-2 chain.

Cypher contributor admits to stealing over $300,000 due to "crippling gambling addiction"

After the founder of the Solana-based Cypher futures trading protocol publicly accused a core contributor of stealing funds, the contributor — publicly known only as "hoak" — has confessed to the thefts.

Cypher was hacked for $1 million in August 2023, but was able to recover around $600,000 of the stolen funds, which they promised to distribute to impact users via a redemption fund. However, over a period of months and unbeknownst to the rest of the team, hoak had been dipping into the recovered funds — taking around half of what was in the fund for himself.

After he was accused, hoak fessed up in a public statement where he wrote that his actions were a "culmination of what snowballed into a crippling gambling addiction and probably multiple other psychological factors that went by unchecked for too long." He continued: "I know likely nothing I say or do will make things better - perhaps other than rotting in jail. To address the elephant in the room, the allegations are true, I took the funds and gambled them away. I didn’t run away with it, nor did anyone else."

SEC sends Wells notice to Robinhood Crypto

Robinhood has disclosed that they received a Wells notice from the US Securities and Exchange Commission in relation to their "Robinhood Crypto" product. This indicates that the SEC believes that some of the assets that can be traded via Robinhood Crypto are securities.

In the past, Robinhood has removed cryptocurrencies from trading after they were alleged to be securities by the SEC, such as Solana (SOL), Cardano (ADA), and Polygon (MATIC) in the wake of the lawsuits against Binance and Coinbase. However, given the SEC's stance that most cryptocurrencies are securities, it seems likely that the SEC believes one or more of the 14 non-bitcoin cryptocurrencies Robinhood offers may also be a security.

Robinhood's Chief Legal Officer issued a statement that "We firmly believe that the assets listed on our platform are not securities and we look forward to engaging with the SEC to make clear just how weak any case against Robinhood Crypto would be."

GNUS.ai exploited for $1.27 million

An exploiter was able to create a fake version of the $GNUS token on the Fantom blockchain, then bridge the tokens to Ethereum and Polygon where they were then sold as though they were authentic. They were able to drain $1.27 million from the project's liquidity pools.

GNUS.ai (short for "Genius", not a reference to the animal) is one of many AI-related blockchain projects that has sprung out of the recent AI hype. This particular one promises to allow people to "utiliz[e] unused cycles" on various computing devices for computation-intensive AI systems, using cryptocurrency for payments.

Cred executives indicted

The former CEO, CFO, and CCO of the cryptocurrency lending service Cred have been indicted on multiple charges involving wire fraud and money laundering. They were charged in connection with their operation of the Cred platform, which went bankrupt in November 2020 after hiding its insolvency for several months.

Cred had claimed to customers that they engaged in only "collateralized or guaranteed lending", hedged their investments, and "comprehensive insurance", but hid that "virtually all the assets to pay the yield were generated by a single company whose business was to make unsecured micro-loans to Chinese gamers." Furthermore, they did engage in uncollateralized lending, did not hedge their investments, and did not hold insurance as they had claimed.

Around $150 million in customer funds were lost in the collapse based on prices at the time, though those crypto assets would have been priced substantially higher at various times since.

Wallet loses over $72 million to address poisoning

An Ethereum wallet was apparently drained of 1,155 wrapped bitcoin (~$72.7 million) when they transferred it to a malicious address that had been operating an address poisoning scheme.

Address poisoning is a scam tactic that takes advantage of crypto traders' tendencies to copy and paste wallet addresses from their transaction histories, since the addresses are long strings of characters that are not practical to type from memory. By creating a new wallet address with identical start and/or ending character strings to addresses used by the victim, and spamming the victim with transactions from that similar address, scammers are sometimes able to get victims to erroneously copy the spoofed address for future transfers.

That's what appears to have happened in this case, when a victim transferred 1,155 wrapped bitcoin — tokens pegged to the bitcoin price meant for use on the Ethereum blockchain — to the malicious address.

The victim and the exploiter later reached an agreement for the return of most of the funds, with the exploiter keeping $7.2 million as a "bounty".

Pike Finance exploited for $2 million in two separate attacks

Pike Finance, a cross-chain lending protocol, was exploited twice in four days as attackers discovered vulnerabilities in the project's smart contracts.

The first attack, on April 26, was enabled by a flaw in the security measures related to transfers of the USDC stablecoin. An attacker was able to change the recipient address and amount, ultimately making off with almost $300,000 in the stablecoin. Pike released a postmortem two days later, acknowledging that the bug had been identified by a third-party auditor but had not been rectified by their team.

When the Pike team went to patch the smart contracts to thwart this attack, they introduced new, even worse vulnerabilities. As a result, on April 30, an attacker was able to upgrade the project's smart contracts to malicious ones, then withdraw $1.68 million in ETH, ARB, and OP tokens.

Pike Finance has offered a 20% reward for the return of the funds or information pertaining to the attacker, and has promised "a plan to make users whole". Pike, which launched in early 2024, is backed by Circle and Wormhole.

Roger Ver arrested for $50 million tax fraud

Portrait of Roger VerRoger Ver (attribution)
Roger Ver, an early bitcoin investor who later became an outspoken evangelist for the fork Bitcoin Cash, has been arrested on tax fraud charges. According to the Department of Justice, Ver evaded almost $50 million in owed taxes by concealing income and lying to tax preparers about his bitcoin assets as he attempted to renounce his US citizenship and become a citizen of the tax haven St. Kitts and Nevis.

Ver was arrested in Spain, and the United States will seek his extradition.

Besides his tax woes, Ver has also been caught up in accusations by CoinFLEX that he owed the platform around $84 million after failing to meet a margin call. Ver has in turn claimed that CoinFLEX owed him money. CoinFLEX filed for restructuring in August 2022.

Changpeng Zhao sentenced to four months imprisonment

Former Binance CEO Changpeng "CZ" Zhao has been sentenced to four months in prison after pleading guilty to money laundering-related charges. The charges were filed in November, and Zhao entered a guilty plea, resigned from the company, and agreed to pay a $50 million fine.

Prosecutors sought a three year sentence for Zhao, while Zhao requested to serve no time. The judge ultimately decided on a sentence closer to the five-month sentence that was being recommended by the Probation Office.

Rain cryptocurrency exchange hacked for $14.8 million

Bahrain-based cryptocurrency exchange Rain was exploited for around $14.8 million dollars on April 29. The exchange did not publicly disclose the hack until the suspicious outflows across wallets on multiple blockchains were noticed by blockchain investigator zachxbt.

After zachxbt sounded the alarm on May 13, Rain admitted that they had had a "security incident", but stressed that customer funds were safe, and stated that the Rain Group had "covered any potential losses resulting from this incident".

ZKasino scam suspect arrested by Dutch police

In the wake of the $33 million ZKasino rug pull, Dutch police have arrested an as yet unnamed 26-year-old who is likely "Derivatives_Ape", the creator of the project. The police also seized assets estimated at more than €11.4 million (~US$12.3 million) including real estate, a luxury car, and crypto. According to police, they began investigating the project only days earlier, after hearing reports of the rug pull on Twitter.

Instagram influencer Jay Mazini sentenced to seven years in prison for crypto fraud

Jay MaziniJay Mazini (attribution)
Jay Mazini, an influencer who often boasted of his wealth on Instagram by doing cash giveaways to random strangers, has been sentenced to seven years in prison after running "overlapping fraud schemes" that scammed victims out of at least $8 million. One of them involved a multi-million dollar cryptocurrency scam in which he would promise to pay higher prices for crypto, and would convince those who were interested to transfer their funds to him by providing doctored images of wire transfer confirmations to suggest that he'd fulfilled his end of the deal.

Mazini also ran a scam targeting the Muslim community in New York, via a company called Halal Capital. In reality, this was a Ponzi scheme, and payouts to his investors were funded in part by the crypto scam he was also running.

Mazini was arrested in March 2021 on kidnapping charges, after he kidnapped and beat someone who might have witnessed his frauds. He was sentenced to five years in prison for that charge, to which he pled guilty. His new fraud sentence will be served concurrently with the kidnapping sentence.

In addition to seven years in prison, Mazini has been ordered to forfeit $10 million. Restitution has not yet been determined.

Samourai Wallet operators charged over crypto mixer operations

Keonne Rodriguez and William Lonergan Hill, founders of the Samourai Wallet, were arrested and charged with conspiracy to commit money laundering and conspiracy to operate an unlicensed money transmitting business. The charges relate to their operation of a cryptocurrency mixer that the DOJ says helped to launder over $2 billion in unlawful transactions. $100 million of that, they say, was connected to dark web markets including Silk Road and Hydra Market. Indeed, Samourai had actively marketed its products to "Dark/Grey Market participants".

Rodriguez was arrested in the United States; the United States will seek extradition for Hill, who was arrested in Portugal.

Samourai Wallet advertised itself as "a bitcoin wallet made for the streets", which would "keep your transactions private, your identity masked, and your funds secure". It touted features including "remote self-destruct", and would hide itself from a phone's applications list. As charges were filed in the United States, the wallet's website began displaying a seizure notice that informed visitors of a coordinated law enforcement action by the US Attorney's Office in the Southern District of New York, FBI, IRS, Europol, and Portuguese and Icelandic police. The app was also removed from the Google Play Store.

ZKasino rug pulls after raising $33 million

A project promising to build a decentralized casino managed to raise $33 million, despite an anonymous team that had exhibited several instances of shady behavior throughout ZKasino's development. The project promised that everyone who bridged ETH to their layer-2 chain would be able to receive their ETH back 1:1 in thirty days.

Instead, the project's creators transferred those more than 10,500 ETH ($33 million) to Lido, an Ethereum staking service. As for the "return" of funds, the project team indeed followed through with their promises to return the crypto... except instead of ETH, depositors received the project's native token, ZKAS, which would vest over a period of 15 months. The project announced that they had calculated the ZKAS distribution based on a discounted rate, "as a favour to our users who have bridged to participate in the ecosystem". Gee, thanks!

One investor in the project wrote, "We made a mistake investing in Zkasino early. ... [I]t sounds like a scam, but 95% of crypto consists of such crap. With memecoins pumping every day, people believe this could be the next one."

It seems that ZKasino's creators have links to other crypto scams, including a failed "ZigZagExchange", which raised around $15 million that was allegedly misallocated to work on the ZKasino project. Crypto sleuth zachxbt had also described the team as "proven bad actors" in December, listing multiple instances in which they had avoided making promised payments.

After the rug pull, the project's planned IDO on Ape Terminal and AIT Launchpad were canceled, and MEXC (which had invested in the project's seed round) canceled the token listing.

Hedgey Finance hacked for almost $45 million

Hedgey Finance, a platform used to manage token claims, lockups, and vesting, was hit with a flash loan attack that drained $44.7 million of customer funds from the platform.

The majority of assets were stolen from Hedgey on the Arbitrum layer-2 network, although around $2.1 million of them were stolen from the version deployed on the Ethereum mainnet.

Hedgey Finance confirmed the exploit, and sent an optimistic and congratulatory message on-chain: "Well done for finding it! We're assuming you executed this exploit as a white hat, so we'd like to get in touch with you to discuss next steps." No on-chain response thus far.

Hong Kong police arrest 72 people, freeze $29 million in connection to JPEX

Police in Hong Kong have arrested 72 people and frozen HK$228 million (~US$29 million) in connection to the collapse of the JPEX cryptocurrency exchange in September 2023. The South China Morning Post has described the collapse as the largest alleged fraud of its kind in Hong Kong.

According to Hong Kong police, they have received more than 2,600 complaints about JPEX, involving HK$1.6 billion (~US$204 million) in assets.

Avi Eisenberg convicted of $110 million Mango Markets heist

A jury found Avi Eisenberg guilty of fraud and market manipulation after he stole $110 million from the Mango Markets defi protocol in October 2022. Although he tried to argue that "code is law", and that his actions were legal as they were allowed by the project's smart contracts, jurors ultimately agreed with prosecutors that his manipulation of token prices constituted fraud.

Shortly after he was identified as the person behind the attack, Eisenberg tweeted that he "was involved with a team that operated a highly profitable trading strategy last week. I believe all of our actions were legal open market actions". Sadly for him, jurors didn't share this belief.

Eisenberg faces up to 20 years in prison.

Roger Stone endorses $TRUMP memecoin with misleading posts

Roger StoneRoger Stone (attribution)
Amid tweets alleging corruption among jurors in his 2019 criminal case, far-right activist and Trumpworld figure Roger Stone has posted several tweets endorsing "MAGA Memecoin", one of the many memecoins with the $TRUMP ticker. In several posts, he's suggested the token enjoys support from Trump himself, mentioning that the token is "the largest holding in Donald Trump's crypto wallet". "Donald Trump has at least $2M in @MAGAMemecoin in his crypto wallet - get yours- this cryptocurrency is going UP!", he wrote in another.

What he failed to mention is that the tokens in Trump's wallet were airdropped to him, likely without Trump even realizing it. Several of Trump's crypto wallets are publicly known, and people send coins and NFTs to them all the time. Trump has no more endorsed Stone's "MAGA Memecoin" than he has the "HarryPotterTrumpHomerSimpson777Inu" tokens that also sit in his crypto wallet.

Elsewhere, Stone disclosed, "My promotion of MAGAMemecoin is, of course, sponsored." I haven't been able to find where he has disclosed the amount he was paid for these promotions, as he is required to do.

$2 million emptied from Grand Base real world asset platform

Grand Base, a real world assets platform built on the Base layer-2 blockchain, has seen $2 million exit the platform in a hack or rug pull.

The team behind the project claimed that the deployer wallet had been compromised, allowing an attacker to drain the project's liquidity pool. Altogether, 615 ETH (~$2 million) was taken from the project.

Grand Base is a platform where users can trade "gAssets", which are crypto tokens that represent stocks in tech companies including Amazon, Apple, Google, Meta, and Microsoft.

tea.xyz causes open source software spam problems, again

The tea.xyz protocol first earned an entry on Web3 is Going Just Great in late February, when their plan to reward open source software contributors resulted in crypto enthusiasts with no intention of participating in OSS opening endless pull requests to claim ownership of prominent OSS projects. This spam was disruptive to said projects, whose (usually volunteer) maintainers had to figure out what was going on and then try to stop the spammy PRs.

Max Howell, the creator of tea.xyz (and creator of homebrew, though he's no longer involved), seemed apologetic, and promised to make changes to the protocol to stop this spammy behavior.

Now, deprived of that avenue, people are just creating massive waves of empty software packages, with nothing other than a "teafile" with their crypto wallet address for rewards, and submitting them to package managers like NPM and RubyGems.

This spam prompted a blog post from RubyGems, who wrote that they had to devote time to strengthening limits on package publishing and "ensuring [accounts] didn't disrupt the community further."

Security researchers at Phylum also wrote up the protocol's impact on the JavaScript world, which has seen as many as 7x as many packages published on NPM as previous daily averages. "Automated sustained spamming of this volume for months on end is rare and does nothing but cause heavy strain on the ecosystem itself, degrading the performance of the ecosystem for genuine users and straining open source security researchers," they wrote.

$26 million liquidated in surprise Pac Finance smart contract change

Pac Finance, a fork of the Aave lending protocol deployed on the Blast blockchain, surprised some of its users as an unannounced and unexpected code change lowered the liquidation threshold. Pac Finance said that they had asked an engineer to make changes to the smart contract, and that that person had unexpectedly decreased the threshold at which positions could be forcibly liquidated. This change resulted in $26 million being liquidated across the project.

Pac Finance has said they are "actively developing a plan with [impacted users] to mitigate the issue."
