Early Friday saw the return of the majority of the money that had been taken from a U.S. government cryptocurrency wallet in what seemed to be an assault on Thursday.
The majority of the money in a government-controlled wallet that had been depleted of $20 million on Thursday was returned on Friday, which added even more mystery to transactions that blockchain researchers had identified as most likely related to a well-publicized heist.
ZachXBT, a pseudonymous blockchain expert, said in a tweet on Thursday that the transactions mirrored a malicious actor’s methodology. Following a sequence of payments that “looked nefarious,” the wallet had also accessed so-called instant exchanges and interacted with a number of decentralized financial protocols.
According to on-chain data gathered by Arkham Intelligence, which includes Ethereum and the stablecoin USDC, around $19.3 million had been returned to the wallet by early Friday. Nevertheless, ZachXBT stated in his Telegram group that money sent to exchanges has not yet been reimbursed.
According to Arkham’s analytics platform, as of this writing, the government-controlled wallet was still missing almost $1.2 million of the total amount it had lost. The U.S. Department of Justice first confiscated the money two years ago in connection with the 2016 Bitfinex attack.
Within an hour of the government-controlled wallet receiving its money back, money began to move to a wallet with an address that started with “0x0Ca.” A transfer of $6.1 million followed a modest quantity of Ethereum. Then, $11.6 million of aUSDC, an interest-bearing stablecoin based on Aave, came after a modest amount of aUSDC.
Not to mention, $7,180 of the stablecoin and $10 of USDC were sent to “0x0Ca.” After another $170 in ETH was sent, the wallet was left in a similar form to how it was on Thursday, with little over $130 of a Trump-themed joke coin. Earlier this year, the wallet received the TRUMP token from an unidentified source.
Before moving digital assets in large quantities, governments have already transmitted modest amounts of cryptocurrency, which resemble test transfers. For instance, in July, the German government sold millions of euros’ worth of Bitcoin via test transactions.
What first sparked concern on Crypto Twitter on Thursday was the government-controlled wallet’s usage of the decentralized lending platform Aave. Approximately $5.4 million worth of USDC and $1.1 million worth of Tether, a stablecoin, have been removed.
The threat actor used the decentralized exchange (DEX) Uniswap and the exchange aggregator 1inch, which sources deals across several venues, to exchange stablecoins for Ethereum, according to a study published on Friday by blockchain analytics company Global Ledger.
Additionally, nine distinct deposit addresses for Binance, the top cryptocurrency exchange, and a business named n.exchange received Ethereum. These are exchanges that use Binance as a source of liquidity, like ZachXBT said.
Binance said in a 2021 blog post that nested exchanges are frequently utilized by fraudsters and “offer less security and fewer guarantees” than the majority of trading platforms. Nestled exchanges frequently have several accounts on several exchanges.
According to the blog post, Binance has previously taken action against nested exchanges, such as Suex, a Russian exchange that was sanctioned by the Office of Foreign Assets Control (OFAC) of the U.S. Treasury Department in 2021. According to the exchange, it proactively closed a number of accounts connected to Suex’s offerings.
