Dust Attacks and Address Poisoning: Crypto's Hidden Threats

As reported in August 2026, Kraken froze several customer accounts after they received tiny, unsolicited transfers linked to HTX, an exchange sanctioned by the EU and UK. The activity was identified as a deliberate dust attack designed to trigger automated compliance systems and disrupt exchange operations.

Dust attacks involve unwanted transactions that target wallet privacy and transaction tracking. In a typical scenario, attackers send microscopic amounts of crypto, known as 'dust,' to identify wallet owners, track transaction networks, or potentially trigger restrictions on regulated exchanges.

However, it's not just dust attacks that pose a threat. Address poisoning attacks directly exploit user behavior by tricking victims into sending crypto to an attacker's address. These attacks can result in the loss of funds and create compliance risks for exchange users.
