An exchange’s abnormal trading during a FLOW incident increased risk for users. After depositing 150 million FLOW tokens, the account converted a large portion to BTC, withdrawing over $5 million, highlighting AML/KYC flaws and causing a significant FLOW price drop.
Flow Foundation reported on December 27, 2025, a vulnerability affected the FLOW token, with suspect trading activity at an unnamed exchange leading to a user risk shift.
A massive deposit of 150 million FLOW tokens to a compromised exchange occurred soon after the vulnerability was identified. This led to significant conversion to BTC, resulting in a withdrawal of over $5 million before suspending network activities.
South Korean exchanges suspended transactions, seeking to secure user assets and stabilize operations.
The event impacted the cryptocurrency market, spotlighting AML/KYC flaws at the implicated exchange. FLOW’s price dropped sharply to $0.079, reflecting a sudden lack of confidence and significant market impact.
Financial implications of the incident are profound, with sharp FLOW price drops and affected user trust. Many tokens were fraudulently converted to BTC, exacerbating concerns.
The breach raises concerns about regulatory compliance in cryptocurrency exchanges. It highlights the urgent need for improved security protocols and more robust user protection measures to avoid fraud and illicit activity.
