Chainalysis attributed last month's $387 million Bitget exchange hack to actors tied to North Korea. Chainalysis said its in-house AI reduced more than 20 hours of estimated manual tracing work to under 10 minutes. Chainalysis said the September 24 breach pushed crypto stolen by North Korea-linked groups in 2026 past $1 billion. Bitget CEO Gracy Chen previously said the attack's patterns matched North Korean hackers, while Elliptic called a North Korea link highly likely.
