At $6.3 billion, it is officially the largest crypto theft on record. ## Key points - Tether CEO Paolo Ardoino confirmed that his firm successfully froze over $1.57 billion in affected USDT tokens. - Circle CEO Jeremy Allaire reported that his company froze over $800 million in USDC assets following the breach. - Intelligence firms TRM Labs and Chainalysis linked the massive cryptocurrency theft to a North Korean hacking unit named TraderTraitor. - Binance co-CEO Yi He and founder CZ confirmed that the platform will cover all losses using corporate capital and the SAFU fund. The scale of the breach that hit Binance on Thursday is difficult to wrap your head around. At $6.3 billion, it is officially the largest crypto theft on record [1]. To put that in perspective, the exchange held roughly $144 billion in assets before the attack, meaning about 4% of its total holdings vanished in a single afternoon [1]. While the numbers are massive, the method was surprisingly surgical. Early investigation points to a single compromised laptop belonging to a DevOps engineer [1]. This breach likely allowed an attacker to gain access to an internal service container. From there, they didn't need to steal private keys. Instead, they submitted unauthorized withdrawal transactions that the system viewed as legitimate [2]. It is a distinction that matters in security circles because it suggests the signing infrastructure itself was tricked into authorizing the drain [2]. ## The infrastructure breach The technical details coming out of the investigation show a high level of sophistication. Security firm Blockaid noted that the attacker bundled 50 EIP-7702 authorizations into a single transaction [2]. This specific maneuver allowed the attacker to delegate execution to a smart contract, essentially turning a standard account into a "sweeper" contract that could drain tokens and Ether [2]. _Photo: Tibe De Kort, Pexels._ Because the attacker had access to the internal service container, the withdrawals looked like ordinary business. In the case of the Bitcoin transfers, 11 separate transactions were sent from a Binance hot wallet, each carrying a valid signature from Binance-controlled addresses [4]. The system functioned exactly as it was designed to, processing what it believed were verified requests. Binance has since stated there is no evidence that any wallet private keys were actually leaked or exposed [1]. The vulnerability sat in the bridge between the human engineers and the automated signing systems. ## Global freeze As the assets began moving, a massive industry-wide coordination effort kicked off to claw back what was possible. This is where the centralized nature of stablecoins became a defensive tool. Within hours, Tether and Circle began blacklisting the affected blockchain addresses [1]. Tether CEO Paolo Ardoino confirmed his firm froze over $1.57 billion in $USDT, while Circle CEO Jeremy Allaire reported freezing over $800 million in $USDC [1]. In total, about $3 billion of the stolen assets have been frozen on-chain [2]. This prevents the attacker from cashing out nearly half of the haul. However, the remaining assets are more difficult to touch. The attacker has been moving funds through decentralized platforms like Uniswap and Aave, borrowing 20,000 wrapped ether worth about $44 million to further obfuscate the trail [1]. _Binancecoin price, last 30 days.

Seventeen of these wallets hold exactly 1,000 BTC each [4]. Unlike stablecoins, Bitcoin has no central issuer who can flip a switch to freeze these addresses. These coins can only be stopped if they hit a centralized exchange or a swap service that cooperates with law enforcement [4]. ## North Korean fingerprints Multiple intelligence firms, including TRM Labs and Chainalysis, have linked the attack to a North Korean hacking unit known as "TraderTraitor" [3]. TRM Labs stated it has "high confidence" in this attribution based on on-chain evidence and intelligence sources [1]. This group, often associated with the Lazarus Group, has a history of targeting crypto infrastructure through social engineering [3]. The tactics used here mirror a February 2025 attack on Bybit, where attackers compromised a developer's credentials to manipulate signing infrastructure [2]. In another case involving the wallet provider Ginco, investigators found that an attacker posing as a recruiter sent a malicious coding test to an employee to gain internal access [3]. Investigator ZachXBT also noted that funds from this Binance breach converged at the same addresses used in a recent $352 million exploit of the Bitget exchange [3]. ## Recovery and SAFU Despite the $6.3 billion figure, the exchange has maintained that user funds are safe. Co-CEO Yi He and founder CZ both confirmed that the platform would cover all losses [1]. The primary mechanism for this is the Secure Asset Fund for Users (SAFU), which was established in 2018 for exactly this type of scenario. The SAFU fund currently holds roughly $1 billion in Bitcoin [1]. Binance has stated it will use a combination of the SAFU fund and its own corporate capital to ensure no users lose money [1]. While withdrawals and deposits were temporarily suspended to resolve the security issue, the exchange has pledged to publish an updated Proof of Reserves once the technical post-mortem is complete [2]. The market reacted sharply to the news, with Bitcoin falling back to $77,000 and $BNB dropping 7% shortly after the breach became public [1, 2]. As of early Friday, the 18,270 stolen Bitcoin remain sitting in the 19 attacker-controlled wallets, having seen no movement since the initial split [4]. ## Sources - CoinDesk, Potential Multi-Billion Binance Hack Hitting Crypto Markets, https://www.coindesk.com/business/2026/10/29/potential-multi-billion-binance-hack-hitting-crypto-markets - Cointelegraph, Binance hack may involve private key misuse, not theft, https://cointelegraph.com/news/binance-hack-may-involve-private-key-misuse-not-theft-blockaid-ceo - Cointelegraph, North Korea’s TraderTraitor linked to $6.3B Binance hack, https://cointelegraph.com/news/north-korea-linked-to-63b-binance-hack-by-crypto-investigators - CoinDesk, Binance hacker splits $1.4 billion of bitcoin into 19 wallets, https://www.coindesk.com/markets/2026/10/30/binance-hacker-splits-usd1-4-billion-of-bitcoin-into-19-wallets-that-no-one-can-freeze Cover: panumas nikhomkhai, Pexels. --- Source: AMK News (https://amk.news).
