$330M Bitcoin social engineering theft victim is elderly US citizen
Update May 1, 2025, 5:10 am UTC: This article has been up to date to incorporate feedback from a Binance spokesperson.
An elderly US particular person is reportedly the victim of a devastating $330 million Bitcoin heist, now ranked because the fifth-largest crypto hack in historical past.
The attacker used superior social engineering techniques to achieve entry to the victim’s pockets, onchain investigator ZachXBT mentioned in an April 30 replace on X.
The hack happened on April 28, 2025, when ZachXBT flagged a suspicious switch involving 3,520 Bitcoin (BTC), valued at $330.7 million.
Following the switch, the stolen stash was rapidly laundered by way of over six prompt exchanges and swapped into privacy-focused cryptocurrency Monero (XMR).
Onchain information reveals that the victim had held over 3,000 BTC since 2017, with no prior historical past of large-scale transactions.
Once stolen, the attacker wasted no time laundering the Bitcoin utilizing a peel chain technique — a typical obfuscation method wherein giant sums are damaged into smaller, harder-to-trace chunks.
“$330M in BTC was received in two transactions, then immediately distributed via peel chains,” Yehor Rudytsia, onchain researcher at Hacken, defined to Cointelegraph.
“Funds started to flow into multiple instant exchanges / mixers with small amounts, then mixers were distributing funds across multiple new wallets. The biggest funnelling chain is now consists of 40+ wallets.”

Over 300 wallets and 20 exchanges had been concerned
Hacken’s inside software, Extractor, an onchain safety monitoring system that gives real-time monitoring of addresses, tracked $284 million value of BTC funneled by way of these chains, which now quantities to round $60 million after repeated “peeling” and redistribution throughout low-credibility exchanges.
Rudytsia mentioned over 300 hacker wallets and 20+ exchanges or fee companies had been concerned, together with Binance.
“We are aware of the incident and are working with law enforcement and industry partners to assist where we can,” a Binance spokesperson instructed Cointelegraph.
“Major problem in cases like this (similar to Genesis creditor’s 4064 BTC theft back in Aug 2024) is that freezing centralized exchange accounts used in the laundering process is hardened due to particularly slow legal process of police reporting and investigations,” Rudytsia added.
Adding to the complexity, the attacker quickly transformed a good portion of the BTC into XMR. The transfer triggered a 50% surge in Monero’s value, with the token briefly reaching $339.
“Once funds are swapped into Monero, tracing becomes virtually impossible due to its privacy-preserving architecture. The chance of recovery drops significantly after this step,” Cyvers Alerts senior safety operations lead Hakan Unal mentioned.
Unal mentioned that the attacker possible had pre-established accounts throughout a number of exchanges and OTC desks, suggesting a excessive diploma of premeditation.
A small portion of the stolen BTC was additionally bridged to Ethereum and deposited into varied platforms, additional complicating monitoring efforts. Investigators have since alerted exchanges for potential freezing of funds.

No acquainted laundering techniques
ZachXBT had beforehand dismissed the speculation that North Korea’s Lazarus Group may have been behind the assault, suggesting unbiased hackers had been accountable.
While attribution stays unsure, specialists agree the laundering techniques present uncommon automation and coordination for a heist of this magnitude.
“So far, we haven’t been able to confidently link this activity to any known hacker group, as the laundering methods used — while sophisticated — don’t clearly match the signature patterns of previously identified actors,” Unal famous.
He really helpful utilizing multisignature (multisig) wallets to eradicate single factors of failure, minimizing publicity to sizzling wallets linked to the web, frequently rotating personal keys, and counting on hardware-based chilly storage to safeguard giant Bitcoin holdings.
In the primary quarter of 2025, hackers stole greater than $1.6 billion value of crypto from exchanges and onchain sensible contracts, blockchain safety agency PeckShield mentioned in an April report.
More than 90% of these losses are attributable to a $1.5 billion assault on Bybit, a centralized cryptocurrency change, by North Korean hacking outfit Lazarus Group.
