Andy Greenberg reports via Wired: More than two months after the start of a ransomware debacle whose impact ranks among the worst in the history of cybersecurity, the medical firm Change Healthcare finally confirmed what cybercriminals, security researchers, and Bitcoin's blockchain had already made all too clear: that it did indeed pay a ransom to the hackers who targeted the company in February. And yet, it still faces the risk of losing vast amounts of customers' sensitive medical data. In a statement sent to WIRED and other news outlets on Monday evening, Change Healthcare wrote that it paid a ransom to a cybercriminal group extorting the company, a hacker gang known as AlphV or BlackCat. "A ransom was paid as part of the company's commitment to do all it could to protect patient data from disclosure," the statement reads. The company's belated admission of that payment accompanied a new post on its website where it warns that the hackers may have stolen health-related data that would "cover a substantial proportion of people in America."

Cybersecurity and cryptocurrency researchers told WIRED last month that Change Healthcare appeared to have paid that ransom on March 1, pointing to a transaction of 350 bitcoins or roughly $22 million sent into a crypto wallet associated with the AlphV hackers. That transaction was first highlighted in a message on a Russian cybercriminal forum known as RAMP, where one of AlphV's allegedly jilted partners complained that they hadn't received their cut of Change Healthcare's payment. However, for weeks following that transaction, which was publicly visible on Bitcoin's blockchain and which both security firm Recorded Future and blockchain analysis firm TRM Labs told WIRED had been received by AlphV, Change Healthcare repeatedly declined to confirm that it had paid the ransom.

Change Healthcare's confirmation of that extortion payment puts new weight behind the cybersecurity industry's fears that the attack -- and the profit AlphV extracted from it -- will lead ransomware gangs to further target health care companies. "It 100 percent encourages other actors to target health care organizations," Jon DiMaggio, a researcher with cybersecurity firm Analyst1 who focuses on ransomware, told WIRED at the time the transaction was first spotted in March. "And it's one of the industries we don't want ransomware actors to target -- especially when it affects hospitals." Compounding the situation, a conflict between hackers in the ransomware ecosystem has led to a second ransomware group claiming to possess Change Healthcare's stolen data and threatening to sell it to the highest bidder on the dark web. Earlier this month that second group, known as RansomHub, sent WIRED alleged samples of the stolen data that appeared to come from Change Healthcare's network, including patient records and a contract with another health care company.

CNBC visited a small group of bitcoin miners who "set up shop at the site of an extinct volcano" near Kenya's Hell's Gate National Park.

Their mine "consists of a single 500-kilowatt mobile container that, from the outside, looks like a small residential trailer." But what's more interesting is it's operated by a startup called Gridless. (According to its web site Gridless "designs, builds, and operates bitcoin mining sites alongside small-scale renewable energy producers in rural Africa where excess energy is not utilized...") Backed by Jack Dorsey's Block, Gridless electrifies its machines with a mix of solar power and the stranded, wasted energy from a nearby geothermal site. It's one of six mines run by the company in Kenya, Malawi and Zambia, powered by a mix of renewable inputs and working toward a broader mission of securing and decentralizing the bitcoin network... In early 2022, [the three Gridless co-founders] began brainstorming creative solutions for the divide between power generation and capacity, and the lack of access to electricity in Africa. They landed on the idea of bitcoin mining, which could potentially solve a big problem for renewable energy developers by taking their stranded power and spreading it to other parts of the continent.

In Africa, 43% of the population, or roughly 600 million people, lack access to electricity.... Africa is home to an estimated 10 terawatts of solar capacity, 350 gigawatts of hydro and another 110 gigawatts of wind. Some of this renewable energy is being harnessed already, but a lot isn't because building the specialized infrastructure to capture it is expensive. Even with 60% of the best solar resources globally, Africa only has 1% of installed solar PV capacity.

Enter bitcoin miners.

Bitcoin gets a bad rap for the amount of energy it consumes, but it can also help unlock these trapped renewable sources of power. Miners are essentially energy buyers, and co-locating with renewables creates a financial incentive to bolster production. "As often happens, you'll have an overage of power during the day or even at night, and there's nobody to soak that power up," said Hersman. He said his company's 50-kilowatt mining container can "take up whatever is extra throughout the day...." Demand from bitcoin miners on these semi-stranded assets is making renewables in Africa economically viable. The power supplier benefits from selling energy that previously had been discarded, while the energy plants will sometimes lower costs for the customer. At one of the Gridless pilot sites in Kenya, the hydro plant dropped the price of power from 35 cents per kilowatt hour to 25 cents per kWh.

The buildout of capacity is also electrifying households. Gridless says its sites have powered 1,200 houses in Zambia, 1,800 in Malawi and 5,000 in Kenya. The company's mines also have delivered power for containerized cold storage for local farmers, battery charging stations for electric motorcycles and public WiFi points.

An anonymous reader quotes a report from Ars Technica: Federal prosecutors indicted a Nebraska man on charges he perpetrated a cryptojacking scheme that defrauded two cloud providers -- one based in Seattle and the other in Redmond, Washington -- out of $3.5 million. The indictment, filed in US District Court for the Eastern District of New York and unsealed on Monday, charges Charles O. Parks III -- 45 of Omaha, Nebraska -- with wire fraud, money laundering, and engaging in unlawful monetary transactions in connection with the scheme. Parks has yet to enter a plea and is scheduled to make an initial appearance in federal court in Omaha on Tuesday. Parks was arrested last Friday. Prosecutors allege that Parks defrauded "two well-known providers of cloud computing services" of more than $3.5 million in computing resources to mine cryptocurrency. The indictment says the activity was in furtherance of a cryptojacking scheme, a term for crimes that generate digital coin through the acquisition of computing resources and electricity of others through fraud, hacking, or other illegal means.

Details laid out in the indictment underscore the failed economics involved in the mining of most cryptocurrencies. The $3.5 million of computing resources yielded roughly $1 million worth of cryptocurrency. In the process, massive amounts of energy were consumed. [...] Prosecutors didn't say precisely how Parks was able to trick the providers into giving him elevated services, deferring unpaid payments, or failing to discover the allegedly fraudulent behavior. They also didn't identify either of the cloud providers by name. Based on the details, however, they are almost certainly Amazon Web Services and Microsoft Azure. If convicted on all charges, Parks faces as much as 30 years in prison.

Terraform Labs and its founder Do Kwon have been found liable on civil fraud charges on Friday by a jury in Manhattan. The jury agreed with the SEC that the two misled investors before their stablecoin's 2022 collapse shocked crypto markets around the world. Reuters reports: The SEC accused the company and Kwon of misleading investors in 2021 about the stability of TerraUSD, a stablecoin designed to maintain a value of $1. The regulator also accused them of falsely claiming Terraform's blockchain was used in a popular Korean mobile payment app. SEC attorney Laura Meehan said during closing arguments that the platform's success story was "built on lies." "If you swing big and you miss, and you don't tell people that you came up short, that is fraud," Meehan said.

Louis Pellegrino, an attorney for Terraform, told the jury on Friday the SEC's case relied on statements taken out of context and that Terraform and Kwon had been truthful about their products and how they worked, even when they failed. "Terraform is still out there, trying to rebuild and make purchasers whole," he said. The regulator is seeking civil financial penalties and orders barring Kwon and Terraform from the securities industry. Kwon, who was arrested in Montenegro in March 2023, did not attend the trial, which began March 25. Both the U.S. and South Korea, where Kwon is a citizen, have sought his extradition on criminal charges.

Bitcoin fell more than 4.76% on Tuesday to $66,134 amid rising Treasury yields and strength in the U.S. dollar. CNBC reports: On Monday morning, it was trading at about $70,000 before data came out showing growth in the manufacturing sector for the first time since September 2022 and investor bets on June rate cuts began to cool. Bitcoin is now off its all-time high, reached on March 14, by about 11%. Ether went down with it, losing 5.6% to trade at $3,240.27. Meanwhile, the 10-year U.S. Treasury yield hit its highest level of the year and the dollar, which has an inverse relationship with bitcoin, hit a five-month high.

Bitcoin's move may have been exacerbated by a large bitcoin holder, or "whale," who transferred more than 4,000 bitcoin to the Bitfinex exchange late Monday night. Data from CryptoQuant shows a spike in that exchange's reserves -- which typically signals a boost in selling activity -- that coincides with the sudden drop in bitcoin price late Monday night. Stocks tied to the performance of bitcoin were dragged down but traded off their lows to end the day.

According to Bloomberg, the U.S. and U.K. are investigating more than $20 billion worth of USDT transactions that have passed through Garantex, a Russia-based crypto exchange. Milk Road reports: If confirmed, the $20 billion in transactions would represent one of the most significant breaches of the sanctions imposed on Russia since the conflict began. However, the sources cautioned that the inquiries are ongoing and that it is too early to draw conclusions given the complexity of crypto transactions. They also noted that there was no immediate suggestion of wrongdoing by Tether.

Key points:

- The transactions under scrutiny were conducted using Tether (USDT).
- The US and UK sanctioned Garantex on suspicion of facilitating financial crimes and illicit transactions in Russia.
- The $20 billion USDT transactions would represent one of the biggest breaches of sanctions imposed on Russia since the start of the war.
- Tether froze assets of entities on the U.S. sanctions list.

Two Texas-based bitcoin miners have turned to the foothills of the Andes mountains in Argentina to mine bitcoin using flared natural gas. CNBC reports: Brent Whitehead and Matt Lohstroh, both graduates of Texas A&M University, have been mining bitcoin on the oil fields of East Texas since 2019. That's when they founded Giga Energy with the goal of taking flared natural gas and turning it into electricity to run bitcoin mines, which are notoriously power-thirsty. On Tuesday, Giga announced its first foray into Argentina, following expansion across the U.S. and into Shanghai. The company is partnering with Phoenix Global Resources, an oil and gas company with operations in Mendoza, and with IT services company Exa Tech to launch a two megawatt bitcoin mine on top of Vaca Muerta.

Giga's system involves placing a shipping container full of thousands of bitcoin miners on an oil well, then diverting the natural gas into generators, which convert the gas into electricity that's used to power the miners. The process reduces CO2-equivalent emissions by about 63% compared to continued flaring -- or burning -- of unused gas, according to research from Denver-based Crusoe Energy Systems. It also turns wasted energy into a valuable asset for oil producers.

On the small pilot site in Argentina, Exa Tech is handling operations on the ground, Phoenix Global is providing the gas and Giga is supplying the equipment. [...] Lohstroh told CNBC that Giga has generated over $10 million in revenue so far this quarter. It's not the only miner that sees opportunity in Argentina, which ranks 12th on the list of the top global emitters of methane, according to World Bank data. Giga's mine is intentionally small to start and isn't intended to be profitable yet. The company first wants to make sure it can successfully import all the necessary equipment before scaling the operation. The mine has been running a test since December, and Lohstroh estimates the site has mined in the range of $200,000 to $250,000 worth of bitcoin. Giga projects the mine is set to reduce CO2 emissions by approximately 30,000 tons per year at the upstream facility. The site is also designed to sell any excess power to the Argentina grid as a way to both generate revenue and curb operational redundancies.

Global bank messaging network SWIFT is planning a new platform in the next one to two years to connect the wave of central bank digital currencies now in development to the existing finance system, it has told Reuters. From the report: The move, which would be one of the most significant yet for the nascent CBDC ecosystem given SWIFT's key role in global banking, is likely to be fine-tuned to when the first major ones are launched. Around 90% of the world's central banks are now exploring digital versions of their currencies. Most don't want to be left behind by bitcoin and other cryptocurrencies, but are grappling with technological complexities.

SWIFT's head of innovation, Nick Kerigan, said its latest trial, which took 6 months and involved a 38-member group of central banks, commercial banks and settlement platforms, had been one of the largest global collaborations on CBDCs and "tokenised" assets to date. It focused on ensuring different countries' CBDCs can all be used together even if built on different underlying technologies, or "protocols", thereby reducing payment system fragmentation risks.

An anonymous reader quotes a report from Reuters: An environmental community group on Tuesday sued Stronghold Digital Mining claiming the company's bitcoin mine in northeastern Pennsylvania that burns waste coal and old tires for energy is polluting nearby communities with dangerous chemicals. The lawsuit by Save Carbon County filed in state court in Philadelphia, also names Pennsylvania as a defendant. The group, a nonprofit whose members live near the bitcoin mine, is seeking compensatory and punitive damages from the company, and an order directing the state to stop allowing the pollution to continue. The group said Stronghold has created a public and private nuisance by releasing mercury into waterways and spewing harmful chemicals like sulfur dioxide into the air from an aging power plant it bought to power its energy-thirsty operations. The state has issued permits allowing the pollution and subsidized the crypto-mine through tax incentives despite having an affirmative duty in the state constitution to protect the environment for its citizens, according to the lawsuit. A Stronghold spokesperson said in a statement that its operations actually clean up land and water in the area by using waste coal left behind by historic coal production in the region. "Stronghold's facilities have cleaned up millions of tons of waste coal and reclaimed over 1,050 acres of once-blighted land, now sports fields, parks, and fishing spots for local communities," the spokesperson said.

An anonymous reader quotes a report from The Register: It's sanctions central at the US Treasury this week as a further 15 are slapped on organizations and individuals in Russia. The Treasury's Office of Foreign Assets Control (OFAC) designated 13 organizations and two individuals -- all concerning financial services organizations, including cryptocurrency exchanges that offered services to already-sanctioned dark web marketplaces in Russia, and those who helped run them. Five of the 13 freshly designated entities were also controlled by individuals who were already sanctioned. The latest round of trade restrictions were placed on those who are believed to have helped evade existing US sanctions.

"Many of the individuals and entities designated today facilitated transactions or offered other services that helped OFAC-designated entities evade sanctions," an OFAC statement read. "These designations build upon OFAC's February 23, 2024 action to target companies servicing Russia's core financial infrastructure and curtail Russia's use of the international financial system to further its war against Ukraine." They follow the initial seven sanctions announced on Monday, all relating to Chinese nationals and members of Beijing's APT31 offensive cyber outfit.

A top executive from the crypto exchange Binance has escaped custody in Nigeria after being arrested for allegedly destabilizing the country's national currency. The Associated Press reports: Nadeem Anjarwalla, the regional manager for Binance in Africa, "fled Nigeria using a smuggled passport," the office of Nigeria's National Security Adviser said in a statement, calling for "whatever information that can assist law enforcement agencies to apprehend the suspect." Anjarwalla, who holds dual British and Kenyan citizenship, had been detained in Nigeria along with another colleague since Feb. 26 when they arrived in the country following a crackdown on the crypto platform. Tigran Gambaryan, the colleague who is an American citizen, remains in captivity.

Nigeria is Africa's largest crypto economy in terms of trade volume with many citizens using crypto to hedge their finances against surging inflation and the declining local currency. Binance stopped all trading with the Nigerian naira currency on its platform in early March after authorities accused it of being used for money laundering and terrorism financing -- without providing evidence publicly. It was not clear how Anjarwalla fled custody. The Abuja-based Premium Times newspaper, which broke the news of his escape, reported that he fled from a guest house in the capital city after guards led him to a nearby mosque for prayers. "The personnel responsible for the custody of the suspect have been arrested, and a thorough investigation is ongoing to unravel the circumstances that led to his escape from lawful detention," Zakari Mijinyawa, spokesman for the office of Nigeria's National Security Adviser said in a statement.

The FTX bankruptcy estate has raised $884 million by selling the majority of its Anthropic shares to two dozen institutional investors. "The sale of the Anthropic shares is a big win for the FTX estate, which pledged in January to pay back the defunct exchange's customers 100% of the value of their holdings at the time of the exchange's collapse," reports CoinDesk. "FTX's FTT token climbed 10% on the news." From the report: According to Friday court filings, the top buyer is ATIC Third International Investment Company, a tech investment company wholly owned by the government of Abu Dhabi's sovereign wealth fund, Mubadala. ATIC has agreed to purchase 16,664,167 shares of Anthropic from FTX for $500 million. Other buyers include Jane Street Global Trading -- an affiliate of the erstwhile employer of former FTX CEO Sam Bankman-Fried -- "certain funds" tied to Fidelity Investments and The Ford Foundation.

An anonymous reader shares a report: About 6,000 older Bitcoin mining machines in the US will soon be idled and sent to a warehouse in Colorado Springs where they'll be refreshed and resold to buyers overseas looking to profit from mining in lower-cost environs. Wholesaler SunnySide Digital operates the 35,000 square-foot facility taking in the equipment from a mining client. The outdated machines are among several hundred-thousand it expects to receive and refurbish around a major quadrennial update in the Bitcoin blockchain.

Known as the halving, the late April event will slash the reward that's the main revenue stream for miners, who will try to lessen the impact by upgrading to the latest and most efficient technology. With electricity the biggest expense, mining companies including publicly traded giants Marathon Digital Holdings and Riot Platforms need to lower usage costs to maintain a positive margin. Their older computers may still bring a profit, just not likely in the US.

Some 600,000 S19 series computers, which account for a majority of machines currently in use, are moving out of the US mostly to Africa and South America, according to an estimate by Ethan Vera, chief operating officer at crypto-mining services and logistics provider Luxor Technology in Seattle. In Bitcoin mining, specialized machines are used to validate transactions on the blockchain and earn operators a fixed token reward. Anonymous Bitcoin creator Satoshi Nakamoto baked in the once-every-four-years halving to maintain the hard cap of 21 million tokens. Next month's event is the fourth since 2012 and the reward will drop to 3.125 Bitcoin from 6.25 now.

"If you've ever jokingly wondered if your search or viewing history is going to 'put you on some kind of list,' your concern may be more than warranted," writes Mashable : In now unsealed court documents reviewed by Forbes, Google was ordered to hand over the names, addresses, telephone numbers, and user activity of Youtube accounts and IP addresses that watched select YouTube videos, part of a larger criminal investigation by federal investigators.

The videos were sent by undercover police to a suspected cryptocurrency launderer... In conversations with the bitcoin trader, investigators sent links to public YouTube tutorials on mapping via drones and augmented reality software, Forbes details. The videos were watched more than 30,000 times, presumably by thousands of users unrelated to the case. YouTube's parent company Google was ordered by federal investigators to quietly hand over all such viewer data for the period of Jan. 1 to Jan. 8, 2023...
"According to documents viewed by Forbes, a court granted the government's request for the information," writes PC Magazine, adding that Google was asked "to not publicize the request." The requests are raising alarms for privacy experts who say the requests are unconstitutional and are "transforming search warrants into digital dragnets" by potentially targeting individuals who are not associated with a crime based simply on what they may have watched online.
That quote came from Albert Fox-Cahn, executive director at the Surveillance Technology Oversight Project, who elaborates in Forbes' article. "No one should fear a knock at the door from police simply because of what the YouTube algorithm serves up. I'm horrified that the courts are allowing this."

mrspoonsi shares a report from the BBC: A former takeaway worker found with Bitcoin worth more than $2.5 billion has been convicted at Southwark Crown Court of a crime linked to money laundering. Jian Wen, 42, from Hendon in north London, was involved in converting the currency into assets including multi-million-pound houses and jewelry. On Monday she was convicted of entering into or becoming concerned in a money laundering arrangement. The Met said the seizure is the largest of its kind in the UK.

Although Wen was living in a flat above a Chinese restaurant in Leeds when she became involved in the criminal activity, her new lifestyle saw her move into a six-bedroom house in north London in 2017 which was rented for more than $21,000 per month. She posed as an employee of an international jewelry business and moved her son to the UK to attend private school, the Crown Prosecution Service (CPS) said. That same year, Wen tried to buy a string of expensive houses in London, but struggled to pass money-laundering checks and her claims she had earned millions legitimately mining Bitcoin were not believed. She later travelled abroad, buying jewelry worth tens of thousands of pounds in Zurich, and purchasing properties in Dubai in 2019.

Another suspect is thought to be behind the fraud but they remain at large. The Met said it carried out a large scale investigation as part of the case - searching several addresses, reviewing 48 electronic devices, and examining thousands of digital files including many which were translated from Mandarin. The CPS has obtained a freezing order from the High Court, while it carries out a civil recovery investigation that could lead to the forfeiture of the Bitcoin. The value of the Bitcoin was worth around $2.5 billion at the time of initial estimates -- but due to the fluctuation in the currency's value, it has since increased to around $4.3 billion.

CoinDesk: The Ethereum Foundation -- the Swiss non-profit organization at the heart of the Ethereum ecosystem -- is under investigation by an unnamed "state authority," according to the group's website's GitHub repository. The scope of the investigation and its focus was unknown at press time. According to the GitHub commit dated Feb. 26, 2024, "we have received a voluntary enquiry from a state authority that included a requirement for confidentiality."

The investigation comes during a time of change for Ethereum's technology. Ethereum is the second-largest blockchain by market cap after Bitcoin, launching in 2015 following an initial coin offering for the chain's native ETH token. Earlier this month, the chain underwent a major technical upgrade, dubbed Dencun, designed to bring down transaction costs for users of Ethereum-based layer-2 platforms.

Refund fraud groups are exploiting lenient refund policies, resulting in significant losses for retailers like Amazon and prompting civil lawsuits and arrests. The scheme has become so pervasive that groups now market their services on Reddit, TikTok and Telegram. CNBC reports: Fraud groups are taking advantage of retailers' lenient return policies, experts told CNBC, which often include unlimited free returns and sometimes even a preference that customers keep the items. It's ballooned into a massive problem for retailers, costing them more than $101 billion last year, according to a survey by the National Retail Federation and Appriss Retail. The figure includes multiple forms of fraud, such as sending back clothing after it's been worn, known as "wardrobing," and returning shoplifted merchandise, the survey said.

In December, Amazon filed a lawsuit against Page and 47 other people across the globe with alleged ties to Rekk, accusing them of conspiring to steal millions of dollars worth of products in a refund fraud operation. Amazon described these services as "illegitimate 'businesses'" that look to "exploit the refund process for their own financial gain to the detriment of honest consumers and retailers who must bear the brunt of increased costs, decreased inventory, and service disruption that impacts genuine customers." An Amazon spokesperson said the company is addressing the issue "head on" through specialized teams and machine learning tools that detect and prevent refund fraud.

Here's how it works: A shopper buys a product online and sends the order information to a group such as Rekk, which then poses as the customer in requesting a refund. Amazon refunds the money to the customer, who then pays the fraud group usually between 15% and 30% of the refund amount, often via PayPal or with bitcoin. That means the customer ends up buying the product for what amounts to a huge discount. The fraud group then pays the conspiring employee at the retailer, typically a certain amount for a batch of packages the employee scans as returned.

A judge in the UK High Court has declared that Australian computer scientist Craig Wright is not Satoshi Nakamoto, the creator of Bitcoin, marking the end of a years-long debate. From a report: "The evidence is overwhelming," said Honourable Mr. Justice James Mellor, delivering a surprise ruling at the close of the trial. "Dr. Wright is not the author of the Bitcoin white paper. Dr. Wright is not the person that operated under the pseudonym Satoshi Nakamoto. Dr. Wright is not the person that created the Bitcoin system. Nor is Dr. Wright the author of the Bitcoin software," he said.

The ruling brings to a close a six-week trial, in which the Crypto Open Patent Alliance, a nonprofit consortium of crypto companies, asked the court to declare that Wright is not Satoshi on the basis that he had allegedly fabricated his evidence and contorted his story repeatedly as new inconsistencies came to light. "After all the evidence in this remarkable trial, it is clear beyond doubt that Craig Wright is not Satoshi Nakamoto," claimed Jonathan Hough, legal counsel for COPA, as he began his closing submissions on Tuesday. "Wright has lied, and lied, and lied."

Roman Sterlingov, the founder of a $400 million crypto-mixing service called Bitcoin Fog, has been convicted of money laundering in a United State District Court on Tuesday. Other charges include money laundering conspiracy, operating an unlicensed money-transmitting business, and violations of the D.C. Money Transmitters Act. CoinTelegraph reports: Sterlingov, however, had argued throughout the trial that he was only a user of the service, and not its operator. His attorney, Tok Ekeland said in a March 12 X post that his team will appeal the verdict. According to evidence presented at the trial, Sterlingov operated Bitcoin Fog from October 2011 to April 2021, which acted as a money laundering service for "criminals seeking to hide their illicit proceeds from law enforcement."

The service moved over 1.2 million Bitcoin over the decade-long operation -- worth $400 million at the time of the transactions -- with the bulk of cryptocurrency coming from darknet marketplaces tied to narcotics, computer fraud abuse and identity theft, the government said. Bitcoin Fog also served distributors of child sexual abuse material. Evidence used to convict Sterlingov found that the "vast majority" of crypto deposited to his crypto exchange accounts came from "Bitcoin clusters" associated with Bitcoin Fog. "Evidence presented at trial clearly showed that the defendant laundered hundreds of millions of illicit funds from the dark web through Bitcoin Fog in an attempt to conceal the origin of those funds," said Internal Revenue Service (IRS) Criminal Investigation Chief Jim Lee.

Two top executives from the crypto exchange Binance have been arrested in Nigeria for allegedly destabilizing the national currency. Quartz reports: According to a Wall Street Journal report, Tigran Gambaryan, head of financial-crime compliance at Binance who previously worked at the U.S. Internal Revenue Service (IRS), and Nadeem Anjarwalla, a British-Kenyan national and Binance's regional manager for Africa, have been held against their will for the past two weeks in the country. As per reports, Nigerian government officials invited Binance executives to discuss an ongoing dispute about the world's largest crypto exchange allegedly driving down the value of their national currency. Gambaryan and Anjarwalla arrived in Nigeria on February 25th; after their meeting with government officials, both were taken to their hotels. Later, they were instructed to pack their belongings and move to a guesthouse run by Nigeria's National Security Agency, as stated by their families, per reports.

The Nigerian government has accused Binance of exacerbating the country's foreign exchange challenges through rate manipulation for profit. The authorities have also accused the crypto exchange of illegal operations and have restricted access to the company's website. There are also reports that Nigeria sought a $10 billion penalty from Binance for processing around $26 billion in untraceable funds in the country. [...] The reason why and how Nigeria's economic crisis is linked with Binance is yet to be found out. Binance is hoping to resolve the matter soon, according to CoinDesk. The report notes that Nigeria is experiencing its worst economic crisis in recent years due to inflation and the devaluation of their currency, the naira.
