A seasoned Bitcoiner has fallen victim to a ZachXBT social engineering scam investigation. This is one of the largest individual thefts of its kind. On August 19, 2025, attackers posing as crypto exchange and wallet support staff convinced the victim to hand over critical wallet credentials. In a single transaction, 783 BTC worth over $91 million was drained. Unlike brute-force hacks, this crime leaned on human trust. This proves again that in crypto, people are the weakest link.
How The Bitcoin Trail Was Scrambled
According to reports from ZachXBT, the stolen funds went through advanced money laundering techniques. The attacker put the Bitcoin into what he called a “clean” wallet first. The wallet then scattered the coin across Wasabi Wallet’s CoinJoin protocol. In this ZachXBT social scam, multiple mixing rounds, peel chains, and test transfers. These actions disguised the movement of the funds, a play very much in the large scale past heists. Also of note is that ZachXBT ruled out state actors like North Korea’s Lazarus Group. Instead, he puts forward the idea that they were highly skilled independent scammers.
It is exactly one year since the 2024 Genesis creditor hack which went off with $243M. Whether a coincidence or a deliberate message, the date which saw such a large scale crypto heist also played out at the same time. It appears to be an elaborate psychological play by the criminals, as much a technical skill.
The Rising Tide Of Social Engineering In Crypto
This issue is a larger scale trend. Social engineering in the form of scams is on the rise. In early 2025, we saw almost 39% of crypto breaches which in fact were a result of some identity theft or phishing. We had fake support teams, fake CAPTCHA “ClickFix” campaigns and remote access. These made personal wallets the main target.
Verify support reports that also means don’t share private keys. By default, treat all unsolicited messages as a scam. As ZachXBT reports, even very experienced investors can fall for scams that use ZachXBT’s social engineering techniques. This happens when scammers combine technical know-how with psychological tactics.
This report of a $91 million loss is more than just a tragic story. It is a note of caution that while we may have break-proof blockchains, humans’ issue with trust is still at large. This is a risk in our digital wealth space.
