Contact-Center.su

A data breach occurred at Contact-Center.su in 2019 which is a Russian service provider for business communications and outsourced call centers. The incident resulted in the exposure of approximately 80000 records. The compromised data included user email addresses and names along with passwords stored as SHA-256 hashes. This leak is significant for B2B services as it exposes corporate contact information and credentials that could be used for credential stuffing or targeted phishing attacks against business clients.
