Chainalysis Restores Tools After User Data Leak

Blockchain analytics firm Chainalysis has restored its Reactor, KYT, and Address Screening tools. The return follows a cyberattack that exposed login data for all platform users.

Transaction monitoring and wallet risk assessment services have resumed operations gradually. The company has begun sending instructions to clients for secure system reconnection. The process requires a mandatory password reset and the renewal of API keys before new transactions can be recorded.

Some investigation tools remain offline. The Investigations API and Rapid Lookup are still under maintenance according to the company's latest updates. No specific timeline was provided for the full restoration of these functions.

The company emphasized that operational status does not guarantee immediate access for all clients. Restoration is occurring in distinct phases for each platform component. Data security remains the central focus following the exposure of access information.
