Binance Hack Surpasses $6B, Experts Warn of AI-Driven Attacks
The record hack at Binance, involving approximately $6.3 billion in cryptocurrencies, is seen by security experts as a preview of AI-era attacks. The breach, attributed to North Korean state hackers, exploited a compromised laptop of a DevOps engineer, bypassing blockchain security. Experts from Check Point, AMLBot, EXANTE, Teroxx, and The Vault warn that AI makes social engineering cheaper and more convincing, leading to faster, automated attacks. They stress the need for independent transaction rule enforcement, improved custody solutions, and better protection of developer machines. About $3 billion in stablecoins (Tether and Circle) have been frozen. Binance has allocated over $6.34 billion in corporate funds to cover losses, including $5 billion already held in the stolen tokens. The incident highlights systemic vulnerabilities in crypto exchanges and beyond.
Binance Hack: Hackers Used Fake Job Interviews, AI Tool
Binance revealed details of the largest crypto theft in history, which occurred on October 29, 2026, when hackers stole approximately $6.3 billion in digital assets within four hours. The FBI attributed the attack to North Korean group 'TraderTraitor', though Binance has not explicitly confirmed this. The attackers spent months infiltrating Binance's systems using social engineering, including fake job interviews, compromised internal AI tools, and malware. Binance has restored 98% of the $6.34 billion in affected assets and frozen $2.85 billion with industry partners, though over $3 billion remains unrecovered. The exchange is collaborating with law enforcement and an independent expert, and is implementing enhanced security measures, including device controls and AI-based anomaly detection. North Korea denies involvement, calling the FBI's accusation a political provocation.
Bitget Loses $352 Million in Hack, CEO Suspects North Korea
Cryptocurrency exchange Bitget reported a hack involving unauthorized transfers from its hot and warm wallets, initially totaling approximately $351.6 million, later reported as $388 million. CEO Gracy Chen suspects North Korean hackers based on IP address analysis, but attribution remains unconfirmed. The attackers breached a central backend system, forged transfer details, and initiated authorized signature processes without compromising private keys. Investigations by Mandiant and SlowMist revealed zero-day exploits in two third-party security products. Bitget suspended withdrawals but has since resumed them for major cryptocurrencies, with trading continuing. Its Protection Fund, replenished to over $300 million using company capital, and over $1 billion in equity cover the loss. Approximately $1.1 million of stolen funds has been frozen, though recovery expectations are low. This incident echoes the February 2025 Bybit hack, also attributed to North Korea, where $1.5 billion was stolen via a compromised Safe{Wallet}.
