Chainalysis says Reactor, KYT and Address Screening are back online with enhanced security; customers must reconnect per emailed instructions
- Follow the Nov 7 reconnect email; if you have not already, submit trusted IPs for the allowlist and reset passwords / rotate API keys before registering transactions.
- Go to the Chainalysis login page directly; ignore reset links in unexpected email while phishing volume is high.
- Reset the same password anywhere it was reused; review your own logs for unexpected KYT API activity since late October.
See our earlier Nov 4/6 impact item and the Oct 30 disclosure.
