Following a major exploit involving 150 million FLOW tokens, Flow Foundation cites AML/KYC concerns while working with exchanges and law enforcement to address security issues.
Upbit continues to classify FLOW as an investment warning until Jan 14, 2026 after halting deposits and withdrawals on Dec 27, 2025 due to a large-scale exploit. Flow Foundation reported AML/KYC deficiencies linked to a 150 million FLOW deposit (~10% of token supply), with over $5 million withdrawn and most funds converted to BTC before the network halt. Kraken, Coinbase and Upbit cooperated in related security measures, Kraken has since restored service, and Flow Foundation is engaging with law enforcement and seeking leadership discussions on the incident.
