What immediate steps did Crypto.com take after the breach?

Question

Accepted Answer

Crypto.com Implemented Immediate Security Measures Following Breach

Crypto.com promptly suspended all token withdrawals and revoked all customer two-factor authentication tokens upon detecting unauthorized transactions on Monday. These actions were taken to allow for an investigation into the security breach, which involved transactions being approved without user two-factor authentication. Following these initial steps, the company required all customers to re-login and re-establish their two-factor authentication.
Suspension of Withdrawals and Token Revocation

On Monday, Crypto.com's risk monitoring systems identified unauthorized withdrawals occurring without the required two-factor authentication. In response to this security incident, the firm immediately halted all token withdrawals to thoroughly investigate the matter. Simultaneously, all existing customer two-factor authentication tokens were revoked to prevent further unauthorized access.
Mandatory Re-authentication for All Users

As part of the enhanced security protocol, Crypto.com mandated that all customers log back into their accounts. This process required users to set up a new two-factor authentication token. This measure ensured that only authorized activity could proceed on the platform after the breach.
Resumption of Services and Additional Safeguards

After a 14-hour suspension, withdrawals were resumed in the early hours of Wednesday. Beyond the immediate corrective actions, Crypto.com revamped its two-factor authentication infrastructure and introduced an additional security layer. This new layer includes a 24-hour delay for the first withdrawal request to a newly whitelisted address, accompanied by user notifications to allow for timely reaction to any unauthorized additions.
