Chainalysis Begins Restoring Screening Services After Disclosing Exposed Password Hashes
Summary
Chainalysis began phased restoration of its KYT and address-screening services on November 6 after a cyberattack disrupted products. The company disclosed that names, usernames, password hashes and live tokens had been exposed, and advised customers to prepare password resets, rotate API keys and provide trusted IP addresses for allowlisting. Chainalysis said it had no evidence that investigation content was accessed or attribution data manipulated, but had not confirmed full restoration of all affected products. The incident highlights the operational risks crypto businesses face when compliance tools are unavailable.
