Cybersecurity researchers from TRM Labs and Chainalysis, alongside onchain investigator ZachXBT, have attributed the $6.3 billion Binance hack to North Korea’s TraderTraitor group. TRM Labs stated it holds "high confidence" in this assessment, citing both onchain and offchain intelligence. The attribution aligns with earlier observations by Blockaid CEO Ido Ben-Natan, who noted that the attack's sophistication and preparation methods resembled known North Korean operational patterns.

ZachXBT provided critical forensic evidence linking the incidents, revealing that funds stolen from Binance were commingled at a single address with assets from an earlier Bitget exploit after moving through THORChain. This overlap suggests the same actor is likely responsible for both breaches, particularly since the Bitget attack had already been attributed to TraderTraitor. Chainalysis co-founder Jonathan Levin corroborated the link, assessing that the group stole approximately $6.4 billion, a figure slightly higher than Binance’s estimated $6.3 billion impact.

This development extends a pattern of US authorities linking TraderTraitor to major cryptocurrency thefts, including the February 2025 Bybit hack and the May 2024 theft of over $300 million from DMM Bitcoin. In the DMM case, investigators determined that attackers used social engineering, posing as recruiters to send malicious coding tests to employees of wallet provider Ginco. This access was then exploited to manipulate legitimate transaction requests, diverting funds to attacker-controlled wallets.
