ZachXBT’s investigation: Unraveling the $282 million crypto heist

A Record Digital Heist: How Did the Hackers Operate?

In the ruthless world of cryptocurrency, security is the name of the game. Yet, even holders of massive capital, often referred to as Whales, are not immune. The investigation revealed by ZachXBT details how two individuals, known by the pseudonyms “Greavys” (Malone Lam) and “Box” (Jeandiel Serrano), managed to steal over 4,000 BTC from a Genesis creditor last August.

Far from smart contract vulnerabilities or brute force attacks, it was a social engineering attack of surgical precision that enabled this theft. The attackers impersonated Google support to gain the victim’s trust. By manipulating security settings and accessing a screen share, they managed to extract the private keys, draining the wallet in mere moments. This type of attack is a brutal reminder that the weakest link in DeFi often remains the human element.

Once the funds were secured, the hackers’ priority was to cover their tracks. This is where ZachXBT’s on-chain analysis becomes crucial. Unlike an immediate dump on the market that would have crashed the price and alerted exchanges, the criminals opted for a massive fragmentation strategy.

The Laundering Circuit: From Bitcoin to Tornado Cash

Tracing the funds reveals a complex route designed to evade the vigilance of authorities and traditional analysis tools. The stolen Bitcoins were not simply transferred; they underwent a “Peel Chain” process. This technique involves splitting amounts into a multitude of small transactions, making visual tracking extremely difficult for the uninitiated.

The funds then transited through various bridges like ThorChain to move from the Bitcoin blockchain to Ethereum. Once on the Ethereum network, the hackers extensively used mixers, notably the infamous Tornado Cash, as well as platforms like eXch. The objective? To break the on-chain link between the victim’s address and the final funds.

However, greed leaves traces. A significant portion of the funds was used to maintain a lavish lifestyle: purchasing sports cars, luxury watches, and extravagant parties in Los Angeles and Miami. These real-world expenditures, coupled with OpSec (operational security) errors identified by ZachXBT, made it possible to link the crypto addresses to the physical identities of the suspects.

Is Crypto Wallet Security Threatened by Social Engineering?

This case raises a critical question for all investors, from small holders to institutional funds: are our assets truly secure? For several years, attack vectors have been evolving. Hackers sometimes abandon code to target user psychology instead.

The collaboration between ZachXBT, forensic investigators, and authorities (FBI, Miami police) enabled the freezing of approximately $9 million and led to arrests. This sends a strong signal to the industry: the blockchain is pseudonymous, but not anonymous. For investors, the lesson is clear: using Cold Wallets and maintaining absolute skepticism toward any external solicitation remain the best barriers against total capital loss.

As Bitcoin continues to test key resistance levels and the market remains volatile, this investigation reminds us that protecting one’s capital is as important as seeking returns. The transparency of the blockchain, often criticized by regulators, has proven here to be the ultimate weapon for justice.
