Kraken temporarily restricted some customer accounts after nearly 12,000 tiny crypto transfers triggered compliance reviews across its platform. The transfers occurred between August 17 and 24, with most transactions worth only cents or a few dollars. Kraken said the activity appeared designed to distribute sanctioned funds across unrelated accounts and trigger compliance checks.
The exchange later restored customer access after reviewing the transactions and determining the circumstances surrounding each account. However, Kraken continues holding the disputed funds separately because they may involve sanctioned entities under applicable requirements. The exchange described the incident as a “dust attack”, although the campaign differs from traditional dusting tactics. Instead of primarily targeting wallet privacy, the activity appears designed to exploit cryptocurrency compliance procedures.
Blockchain analytics firm Arkham Intelligence identified the sending wallet as connected to HTX, formerly known as Huobi. HTX denied initiating the transactions and said it was investigating possible address misattribution or malicious third-party activity. The identity and motive of the sender remain unresolved. The incident carries additional significance because sanctions involving HTX-related entities recently intensified. The European Union’s restrictions concerning Huobi Global S.A. took effect on August 23, shortly before the transfer campaign ended, while the United Kingdom had also designated Huobi Global S.A. under its Russia sanctions regime earlier this year.
The episode underscores a difficult balance for crypto exchanges: platforms must enforce sanctions while distinguishing between deliberate transactions and unwanted blockchain transfers that customers cannot prevent. As investigations continue, attribution remains unresolved.
